        * applied copyright patch from Josh Wilmes

2003-06-14 13:50 dan
        * Moved the registers out of the context structure, since they
          really aren't context
        * Changed the register stack frames to hold only 16 registers
          rather than 32, added half-set push and pop ops, and reworked
          the full set push/pops to do two half-set push/pops. Should
          speed up saving register data on calls, since we usually only
          care about the top half of the registers anyway.
        * Started committing some of the new class/object framework
        * Remembered to finally start updating the Changelog

2003-03-18 03:50  ask

        * Various files

        * memory.c, resources.c: Partial fix for GC's memory trouncing. At
        least we consider the PMC and Buffer free pools worth collecting,
        and initialize the Buffer pool stuff.  Still not 100% correct,
        though.

        * types/: bignum.c, bignum_atest.pl: Added a couple of quick routes
        through addition and subtraction.  Also added the ability to run
        all the tests, including the ones which deal with overflow and
        underflow.  These fail, but that's expected.  Soon they'll pass.
        Then I'll show them.  Yesssssss.  Tessssssssts my precioussssss,
        passsssssssings tesssstsssss.

2002-03-17 20:06  ajgough

        * types/: bignum.c, bignum.h, bignum_test.pl: Modified
        check_(under|over)flow to test bignumbers, rather than values.
        context now carries E_limit, from which max and min exp are found.

        Added a default-context-creating function (although this isn't the
        same as either of the default contexts defined in the eda).

2002-03-17 13:31  ajgough

        * types/: bignum.c, bignum.h: Made BN_round and BN_iround so that
        exported version matches prototypes of other public functions.

        readiness for nicely telling your caller about any oddness you've
        caused in the persuit of flow.

        * interpreter.c, resources.c, docs/pdds/pdd09_gc.pod,

        * resources.c, vtable.tbl, classes/default.pmc,

2002-03-16 16:57  ajgough

        * types/bignum.c: Ok, I worked out how to not have lots of tabs.  I
        feel a little more virtuous now.  Really I do.  You might not
        believe me, but you should.  perl -pne 's/\t/        /g', if you're
        curious.

2002-03-16 16:57  josh

        * packfile.c, packout.c: M-x untabify is my new friend.

        * trace.c, resources.c: Minor whitespace tweak for the benefit of
        check_source_standards.pl

2002-03-16 16:50  ajgough

        * types/: bignum.c, bignum.h: More documentation, separate
        functions into public and private sorts, some initial stuff to cope
        with over and underflow correctly.

2002-03-16 16:49  josh

        * resources.c: Re-indented (sorry bout the big diff)

        silly people (such as me) running Configure with
        /usr/local/bin/perl (which is 5.004_05) and not realising their
        mistake until the pmc subdirectory, where the first qr// is
        encountered.

        Syntax error messages don't tell you what you did wrong. This does:

        /usr/local/bin/perl Configure.pl Perl 5.00503 required--this is
        only version 5.00405, stopped at Configure.pl line 10.

        argument to the init() vtable method so PMCs have the option to
        know how to size themselves at creation. size could be N elements
        or a byte count, depending on the PMC or it may simply be ignored.
        Overloaded 'new' opcode for optional arg.

2002-03-10 21:15  mrjoltcola

        * lib/Parrot/Assembler.pm: Minor patch to the assembler for the
        new_p_ic_ic opcode to work same as new_p_ic (looks up a named
        class).

        Also added small hack for .sub directive (which simply translates
        to a label, however we might eventually want to collect these to
        validate bsr calls.

2002-03-10 15:09  ajgough

        * types/: bignum.c, bignum.h, bignum_atest.pl, bignum_test.pl:

        BN_comp to take a context, so that an is_zero check doesn't clobber
        negative zeros.

2002-03-09 22:19  ajgough

        * types/: bignum.c, bignum.h, bignum_atest.pl, bignum_test.pl:

        traps and flags are now enabled and tested for all the standard

        * types/: bignum.c, bignum.h, bignum_test.pl: Added handling of
        special values to the string conversion functions, some other
        functions now need context (to let -0 pass through really_zero)
        which have also been added.

2002-03-09 01:47  josh

        Introduced exception handlers and exception flags to context, will
        allow support of extended standard.  Unified exception checking
        mechanism (sort of) and made minimal changes to bulk of code to use
        this.  Tests pass, I'm happy, and further changes will happen more
        gradually.

        we've come to *any* sort of agreement with these, although we
        really, really, need to.  3) I forget the third thing.  4) But I
        thought of a fourth.  5) I've now remembered the third thing: IIRC,
        ANSI C states that enums will fit within the smallest type (int or
        greater) that can hold the values. Is that actually correct, and
        does it state whether unsigned is preferred to signed for
        non-negative enums? 6) Since I'm no longer constrained by "three"
        or "quick", I'm going size_t happy for a lot of memory-related
        storage.  (That's good.  No sense wasting the size or performance
        of an UINTVAL for strange values of UINTVAL.)  I'm also using it in
        a couple other internal things (like the GC stat counters, seen
        here).  Size and performance, again, and unpromotable to a bigint,
        so we know that we (theoretically) will wrap.  However, size_t
        isn't the best choice for the type.  (Not that there's anything
        wrong with size_t, just that it shouldn't be called size_t.)  Any
        thoughts?  I was thinking of just doing unsigned int, because,
        IIRC, int is usually the natural word size, and will be most
        efficient.  Thoughts? 7) I forgot what the fourth thing I thought
        of was while writing down the others.  Sorry.

        * docs/pdds/: pdd0.pod, pdd00_pdd.pod: The pod version of PDD 0 in
        CVS seems to have several chunks missing out of it, too.  This
        patch is simply an administrative patch, with the differences
        between my last version, and the one currently in there.  There
        will be a forthcoming patch for some minor tweaking to the PDD, but
        I wanted a common baseline before I make any (potential) semantic
        changes.

        There's only one semi-major change, which noone needs to worry
        about just yet.  That's a change from PDD Format 1 to PDD Format
        6.0 - rationale can be found under 'Standard (Version #)' of the
        STANDARDS TRACK infomation.  Don't worry about this yet, because it
        should be 6.0.0, and we need to discuss Perl versus Parrot with
        PDDs.

        no PMCs yet)

        This patch now implements a real copying collector. We trace from
        our root set and compact the contents of Buffer structs.

        Todo:

        *) It's very STRING-centric and doesn't handle memory stuffed in
        Buffers.  But, then, we don't have pool allocation for Buffers
        either, and we need to have that soonish for this to work.

        *) Doesn't trace PMCs, so if you trigger a collection and there's
        memory or STRING structs only accessible from PMCs, you'll fail
        horribly. That needs fixing too

        *) Better algorithms for when to trace or collect vs when to just
        go allocate more memory from the system. Should probably be more
        cache friendly too.

        include/parrot/parrot.h: this patch adds support for the freely
        available borland c++ 5.5.1 compiler

        depends on: - josh's patch to remove ssize_t from CPrederef.pm -
        working borland compiler (compiler must know where to find headers
        and libs) - Perl's Config.pm modified to use cc='bcc32.exe' not of
        cc='cl.exe' - a working make utility (borland make doesn't work,
        nmake does)

        changes: - add bcc in hints/mswin32.pl - clean up for msvc++ in
        hints/mswin32.pl - remove a space from Configure.pl (very very
        important for bcc) - add a O_BINARY flag to open() in pdump.c,
        embed.c (required by bcc) - define O_BINARY 0 when it's not defined
        (win32 knows it, linux not)

        and the why: - parrot is MUCH faster when compiled with borland c
        (make test on p2-450, 320MB):   * msvc++: 313 seconds   * bcc: 251
        seconds

        CPrederef.pm to make to generated code compile with the MS
        compiler.

        fixes: - ms compiler allows inline only for c++, for c there's
        __inline - ms header files knows nothing about ssize_t

        work for Windows yet. The libparrot.a target might need to be
        modified to at least prevent it from confusing make on Windows; I
        don't know.

        segfaults in build_asm in jit.c when using -j. It also breaks the
        bounds checking on opcode address in runops_slow_core.

        calculations.

        This is what keyed set ops look like. Remember, however, that for
        keyed functions, all operands must be PMCs. set(PMC, PMC, INT)
        means $1 = $2[$3], not $1[$2] = $3. set(PMC,PMC,PMC) is so
        obviously ambiguous that you ought to use the 4-arg version
        instead.

2002-02-10 23:12  jgoff

        * classes/: array.pmc, perlarray.pmc: Properly allocate
        SELF->data's array of PMC* data in array and perlarray.pmc.  This
        isn't tested yet, but should be fairly straightforward.  PerlHash
        needs to be finished before the system will compile again, and that
        should be done in the next few days.

        yet.

        members, and deleted the _index members from the perlscalar
        classes.  Basic cleanup, and getting ready for _keyed functions.

        * vtable.tbl, lib/Parrot/Vtable.pm: vtable.tbl got some minor
        changes in order to give the whitespace rules a little workout, and
        do a little bit more testing. No actual structural changes were
        made.  lib/Parrot/Vtable.pm got an interface change, and more
        importantly should be ready to support the new '_keyed' attribute,
        which will work roughly thus: PMC* src_value gets remapped to 'PMC*
        src_value' followed by 'KEY* src_key'.  This will be how the new
        _keyed operators will function, and those should be written within
        a few days.

        * vtable.tbl, lib/Parrot/Vtable.pm, t/pmc/perlstring.t: Changed the
        format of vtable.tbl to get rid of the tab-dependence.  The format
        now looks roughly like this:

        init() # 'void' and 'unique' are assumed INTVAL type ( ) # 'unique'
        is assumed str void concatenate (PMC* value, PMC* dest) # Nothing
        assumed here, but note the C-like prototyping.  Also had to disable
        one test that depended upon 'concat_p_p_s', which isn't necessary
        anyway.

        Vtable.pm will change again when the type '_keyed' is added,
        because that requires remapping parameters slightly differently
        again.  Also, note that it assumes 'value' is the first parameter
        in the list. This assumption will go away at the same time.

        Moving the internal KEY structure from the cache.struct_val member,
        where it doesn't really belong, to the internal SELF->data member.
        This frees up the cache/type members for other usage.

        This is the first step in moving PMCs to the point where we can do
        multidimensional PMC handles. The next step is to change the
        assembler to accept the syntax of 'set P0["foo"],7'.

        jit_struct.h is jit.c, so I feel that the Makefile dependencies
        should reflect this, and not cause a gratuitous recompile of
        everything.  There are probably other auto-generated header files
        that world+dog should not depend on.

        * Makefile.in, lib/Parrot/Test.pm, t/harness:
        Added two new make targets:

          * testp: Like 'make test', but passes -P to t/harness, so you get
        to
            see how broken predereferencing is.

          * testj: Like 'make test', but passes -j to t/harness, so you get
        to
            see how broken JIT is.

        Now, anyone who wants to see how good all three ways of running are
        can do so, at the cost of about 3x the time.

        * Configure.pl, MANIFEST, testparrotfuncptr.c: This patch allows
        parrot to mostly-build with tcc.  It allows one to skip compiling
        the JIT stuff (by specifying --define jitcapable=0), and it
        introduces a test program which gives a friendlier error in this
        case for compilers which are as picky as tcc is about function
        pointer conversion.

        If anyone figures out the proper way to cast these function
        pointers this may not be necessary.

            output_* now returns whether the test passes or fails

            Parrot::Test no longer exports Test::More's functions.  Instead
        they
            can simply be used together.  The few tests which used
        Test::More
            features (ie. skip) have 'use Test::More' added.

            I ditched the export_to_level() crutch.  Do we expect parrot to

        lib/Parrot/OpTrans/CPrederef.pm, chartypes/unicode.c,
        chartypes/usascii.c: This patch adds a few more macros for .ops
        files to use. In addition to the existing

         goto OFFSET(...)
         goto ADDRESS(...)
         goto POP()
         goto NEXT()

        it adds

         expr OFFSET(...)
         expr ADDRESS(...)
         expr POP()
         expr NEXT()

        This is intended mainly for use in helper functions in .ops files,
        but also for ops that need to eg push the address of the next
        opcode onto a stack. The only place this currently happens (outside
        of my private code) is in the bsr opcode, which previously
        hardcoded the computation.

        This patch also makes ops2c.pl move the CUR_OPCODE #define a bit
        higher in the generated file so that it can be used by static
        functions in the preamble.

        Finally, I ran into a parentheses matching problem -- should goto
        OFFSET(...) rewrite    \bgoto\s+OFFSET\((.*)\) or
        \bgoto\s+OFFSET\((.*?)\)

        It was done inconsistently for the different calculations, and of
        course neither are correct because you really want matching
        parentheses. But that seems like too much bother. (Currently,
        there's only one place that uses anything other than $n in the
        parentheses, and that's the enternative() op.) So I made them all
        .*? but emulated recent POD by also allowing (( ... )) (that's two
        parenthesis with a space padding the body.)

        The generated core_ops.c and core_ops_prederef.c files after this
        patch are identical except for the CUR_OPCODE and REL_PC macros
        getting moved a little higher, and the bsr in the regular path (not
        prederef) uses 'CUR_OPCODE' instead of the hardcoded 'cur_opcode'.

        In summary, this is a big wad of meaningless changes for the
        current code. But it will make adding some opcodes easier in the
        future, and cleans up a small nit in the current bsr.

        4 (the highest, one above the default level 3). It turns off two
        level-4 warnings for 'unreferenced formal parameter' and 'named
        type definition in parentheses', the latter of which was turning up
        warnings in MS VC headers.  Level 4 warnings also helped me find a
        couple of other lurking bugs in the parrot code.

        Replaces the various fprintf/exit combos with calls to
        internal_exception, which uses var_args to emulate printf. Various
        exception types were added as well. These are probably temporary
        until a real exception system arrives.

        Fixed some places in the IO code where wrong functions were being
        called, or put into the vtable.

        It creates a new opcode 'enternative', and uses this to support a
        mixed model of interpretation and execution of compiled C code.

        available except for obscure.ops.

        In addition, it makes it so that if your answer to a question
        starts with '+', it will concatenate it to the default.  For
        example:

        What C compiler do you want to use? [cl] +HAHAHA!!!

        will result in $PConfig{cc} eq "cl HAHAHA!!!".  While that example
        is not terribly useful, it is quite useful with things like
        command-line flags and the like.

        Finally, it contains a couple tweaks so that my syntax-highlighting
        editor recognizes some heredocs correctly.  :^)

        and so
         writes a load of junk in core_ops.pod. Applied patch fixes.

        * classes/: perlint.pmc, perlnum.pmc, perlstring.pmc: The PerlInt
        logical-or is using get_integer instead of get_bool for logical
        operations. This patch corrects that.

        Perlnum and perlstring have working get_bool's, so the default
        logical_or and logical_and should be sufficient. The empty methods
        are pointed to the default logical_or.

         set_* create appropriate Perl* result.
         get_* simply grabs needed bit of cache.*_val

         Other methods do the rightest thing I can think of, at the moment.

         None yet cope with overflow, the modulus operation needs to be
        checked as
        I don't know quite which semantics we really want.

              * Added header comment with CVS Id variable, and a few other
                block header comments.

              * Uses new Parrot::BuildUtil module to determine the Parrot
                version.

        messages
                to 79 columns.

              * Added 2002 to the Copyright statement.

              * Added new configure variables: VERSION, MAJOR, MINOR and
        PATCH

              NOTE: Please see the 'Alas perl5.7.2' comment. 5.7.2 is
        greater
              than 5.6.0, but the comment implies it isn't.

          * Makefile.in:

              * Added $(SO), $(A) and $(AR_CRS) defines for library
        building.

              * Added $(RM_RF) define for removing directory trees

              * Grouped generated files into two classes: "sticky" (made by
        configure,
                persisting across 'make clean') and 'fluid' (made during
        the build
                process, deleted by 'make clean').

              * Added header comments.

              * Added target for test_prog linked with shared library.

              * Added rules to build shared libraries in blib/lib. The
        libraries are
                built with trailing version numbers in their file names,
        and then
                symbolic links are created for shorter and no version tag
        variants.

              * Added some missing dependencies

              * Added some missing 'make clean' targets.

              * Added 'make realclean' target that deletes files created by
                Configure.pl (including Makefile), forcing a re-configure.

              * Added a 'status' CVS target.

          * VERSION: New file, contains only the version. This version
        number is
            propagated to a few places, such as the core oplib version
        number. This
            reduces the amount of coordination that has to happen to get
        version
            number stuff throughout the tree in sync and updated prior to
        cutting
            a new release. Feel free to grep for '0.0.3' to see the other
        files
            that contain the version number (but, do that in a fresh CVS
        copy, or
            after doing 'make realclean').

          * config_h.in: Renamed PARROT_CORE_OPLIB_*_VERSION to
        PARROT_*_VERSION,
            since the oplib and Parrot itself share a version number now.
        Added
            PARROT_PATCH_VERSION (the third component) and PARROT_VERSION
        (a
            string).

          * core.ops: Uses new notation "VERSION = PARROT_VERSION" instead
        of
            specifying the version by hand. Non-core oplibs will set this
        to
            a quoted dot-string with three natural number components
        without
            leading zeros.

          * interpreter.c: Make use of PARROT_VERSION to simplify some
        sprintf()s, and
            to get the complete version number in the resulting strings
        (including the
            new PATCH portion).

          * make_vtable_ops.pl: Put the "VERSION = PARROT_VERSION" line int
        the
            generated file.

          * obscure.ops: Use the new "VERSION = PARROT_VERSION" technique.

          * ops2c.pl: Account for the PATCH version, too. This affects the
        name of the
            oplib init function, and the oplib info struct initializer.

          * Parrot/BuildUtil.pm: New file for reading in and validating the
        contents of
            the new VERSION file. Other build utilities could go here in
        futuer.

          * Parrot/OpsFile.pm:

              * Allow three components in version number, and require that
        the value
                be in double quotes.

              * Allow "VERSION = PARROT_VERSION", substituting the shared
        Parrot
                VERSION in that case.

          * include/parrot/oplib.h: Add the patch_version member.

        vtables appropriately.  Also tests for same, new pmc_perlstring.t
        to hold tests specific to PerlStrings, as the pmc.t file is taking
        too long to run and slowing down my thought processes.

        Changes to strings.c etc to take string functions.

        Some changes to the strings docs, but not yet complete.

        Also, PerlString was copying pointers to strings, rather than
        strings themselves, so some action-at-a-distance bugs were creeping
        in, I think I've fixed this so everything works nicely.

        platforms/win32.c, platforms/win32.h:
        Initial code for dynamic loading of oplibs, applied for now to the
        loading of the core_prederef oplib when the -P flag is passed to
        test_parrot.

          * MANIFEST: Added entry for the new file include/parrot/oplib.h.

          * Makefile.in:

              * Added libcore_prederef_0_3.so to the shared target.
              * Added build rule for libcore_prederef_0_3.so.
              * Added dependencies on Parrot/OpsFile.pm and Parrot/Op.pm
                to Parrot/OpLib/core.pm, core_ops.c and
                core_ops_prederef.c.

          * config_h.in: Added defines for constants used to locate the
            core oplib's init function, and the core_prederef oplib for
            dynaloading.

          * core.ops: Added a VERSION = 0.3 line near the top. This is now
            required by Parrot/OpsFile.pm.

          * interpreter.c:

              * Added init_prederef() and stop_prederef() functions to load
                and unload the core_prederef oplib when we are in prederef
                mode.

                NOTE: In all likelihood, the prederef stuff has a rapidly
                dwindling time-to-live. The JIT should provide vastly
        superior
                performance, and loading an alternate set of core_ops isn't
                the real direction for the dynaloading stuff. Loading
                *additional* ops is. It does provide a handy test case for
        the
                general idea for now, though.

              * Gets the core copcode table, etc. via the core oplibs oplib
                info pointer, as returned by the core oplib's init
        function.

          * ops2c.pl

              * Make use of the version, major version and minor version
                stuff parsed by Parrot/OpsFile.pm

              * The only exported symbol in the generated files is the init
                function now, since that returns an oplib info struct
                pointer, and all the important stuff can be found there.

          * ops2pm.pl: Put the oplib version in the generated .pm file.

          * test_main.c: Small changes necessitated by changes in the names
            of some members of the interpreter struct.

          * trace.c: Small changes necessitated by changes in the names
            of some members of the interpreter struct.

          * Parrot/OpsFile.pm: Require a "VERSION = x.y" line before any
            ops are found.

          * include/parrot/interp_guts.h: Small changes necessitated by
            changes in the names of some members of the interpreter struct.

          * include/parrot/interpreter.h: Include the new
            include/parrot/oplib.h header. Small changes to the oplib-
            related members.

          * include/parrot/oplib.h: Define the type of the oplib init
            function, and the struct type for the oplib info.

          * platforms/*.[hc]: Remove the second argument to Parrot_dlopen()
            since not all platforms have it. For those that do, a default
            second argument is provided.

          * Ops added set_s_s, set_s_sc, bsr_i and eq_s_sc but using calls
        to C
            functions.

          * Added JUMP(END) to place the number of bytes to the end of the
        current
            op.

          * The *.jit files syntax changed.

          * Added jit/i386/lib.jit to place handly functions as jump that
        take as
            argument the address where is the opcode number to jump to.

          * There is a bug at some point, but I will start writing
            jit/i386/string.jit and jit/i386/stacks.jit so that we don't
        have use
            calls, which make the jit as slow as the interpreter.

        Changes to syntax of .ops files and refactoring of ops2c*.pl and
        pbc2c.pl.

          * Removed ops2c-prederef.pl

          * (unrelated) Removed vestigial Parrot/Opcode.pm file.

          * Added Parrot/OpTrans.pm, Parrot/OpTrans/C.pm (needed for old
            functionality of ops2c.pl), Parrot/OpTrans/CPrederef.pm (needed
            for old functionality of ops2c-prederef.pl), and
            Parrot/OpTrans/CGoto.pm (needed for functionality of pbc2c.pl).

            "OpTrans" == "Op Transformation"

          * Makefile.in modifications to call "ops2c.pl C" where it used
            to be just "ops2c.pl", and "ops2c.pl CPrederef" where it used
            to be "ops2c-prederef.pl".

          * core.ops and obscure.ops changes to syntax. Semantics are
            identical with previous version:

              return HALT         -->  HALT()
              return AUTO         -->  goto NEXT()
              return RETREL(...)  -->  goto OFFSET(...)
              return RESTART(*)   -->  restart NEXT()

            Also, pop_generic_entry() stuff (local var + 5 lines of code)
            for dest-less branch ops replaced with new notation "goto
        POP()",
            which uses the new pop_dest() function in stacks.c. This also
            allowed these ops to become 'inline' ops, since they no longer
            have local variables.

            The 'ret' op also became simplified to just "goto POP()", and
            also became an inline op.

          * interpreter.c reflects the change in type name:

              prederef_op_func_t   -->  op_func_prederef_t

            that occurred in include/parrot/op.h

          * make_vtable_ops.pl uses "goto NEXT()" where it used to use
            "return AUTO".

          * ops2c.pl is now generic. Its first argument is the last
            package name component of a subclass of Parrot::OpTrans. These
            subclasses all have full names of the form Parrot::OpTrans::*.
            An instance of the class is created and later consulted for
            various bits of information needed to generate the C code.

          * pbc2c.pl now uses an instance of Parrot::OpTrans::CGoto to
            contain its transformation rules.

          * stacks.c has a new function pop_dest() that pops a destination
            off the control stack. include/parrot/stacks.h has the
        prototype.

          * Parrot/Op.pm now supports the syntax generated by
        Parrot::OpsFile
            for the "goto POP" case.

            Also, the source() method now expects its second argument to be
            an object that ISA Parrot::OpTrans. Methods of this object are
            called to perform the substitutions.

          * Parrot/OpsFile.pm supports the change in notation mentioned
            above.

          * docs/intro.pod reflects these changes.

          * include/parrot/op.h: Renamed type prederef_op_func_t to
            op_func_prederef_t because it made the implementation of the
            shared ops2c.pl easier.

2001-12-21 13:47  gregor

        * Configure.pl, config_h.in, interpreter.c, test_main.c:
        Both test_parrot (via test_main.c) and the intepreter itself (via
        interpreter.c) use the JIT_CAPABLE config to decide whether to
        actually attempt JIT operation, or to complain.

        Changes to the format of *.ops files. An attempt to provide hints
        for future opfunc processing logic that wants to know if an opfunc
        is simple enough to JIT (e.g.) inline, or not.

          * A fix to Gregor's last Configure.pl update.

          * Remove the need for hardcoded "\n" at the end of the "%f"
            format for printing floating-point numbers.

          * New, improved *.jit syntax for references to registers,
            e.g. INT_REG[n].

          * Support for C() improved.

        * jit2h.pl:
        Off-by-one error fixed.

2001-12-20 14:18  simon

        * jit/i386/core.jit:
        Just a noop. It's the only machine code I know.

        * Configure.pl, Makefile.in, jit2h.pl:
        Attempt to fix Win32 builds.

          * No more empty braces in include/parrot/jit_struct.h

        Also:

          * ${jitarchname} has the *bsd -> bsd substitution on it, but
        ${archname}
            does not.

        * MANIFEST, core.ops, t/op/key.t: MANIFEST - Removed t/op/key.t
        core.ops - Removed key operators, they should be hidden from the
        assembler.  t/op/key.t - No need to test the nonexistent key
        operators.

2001-12-20 00:13  ajgough

        * core.ops, t/op/stacks.t: Added tests for entrytype op, noticed
        that asking for type of entry at depth causes segfault as stack is
        zero based, fixed cmp in core.ops to reflect this.  Last test is
        skipped as we don't do exceptions right yet.

2001-12-19 19:11  ajgough

        addition of the clone operator.

2001-12-18 20:06  gregor

        * interpreter.c, include/parrot/interp_guts.h:
        Performance improvements to the predereferencing code path
        suggested to me over lunch yesterday by my friend John Kennedy.
        The goal is to remove the additional test in the inner loop that
        was checking for NULL to decide whether or not to call the
        prederef() function. Also moved pc & pc_prederef syncing outside
        the inner loop.

          * Changed the prototype of the prederef() function in
            interpreter.c to match that of an opfunc.

          * Instead of initializing the prederef void * array with NULL,
            we initialize it with pointers to prederef().

          * prederef() now returns the prederef_pc passed in, so that
            after predereferencing, the same location is executed, but now
            with the real code being called.

        Thanks to: John Kennedy

        Welcome to the Just-in-Time Predereferencing Patch!

        This patch implements a "predereferencing" mode for parrot. That
        means that a lot of the dereferencing you see in DO_OP and in the
        opfuncs is done up front (really, JIT) rather than as and each time
        we execute each op in the byte code stream.

        This works by creating an array of void pointers with the same
        number of elements as the byte code array. This array starts out
        life zero-initialized.  Each time we go to execute an op, we check
        first to see if we have a NULL pointer at *cur_opcode. If so, we
        know we haven't done our predereferencing yet (this is the JIT
        part), so we call the prederef() function with sufficient args that
        it can go look up opfunc pointers and op arg types and put the
        opfunc and arg pointers at cur_opcode[0] .. cur_opcode[N - 1],
        where N is the number of args (counting the op itself as one arg).

        We assume that sizeof(INTVAL) <= sizeof(void *), so we can continue
        to have inline INTVAL constants.

        I've been getting about a 22% speed increase over vanilla code path
        when I compile with -O0. Advantage decreases at -O9 here. I tested
        with mops.pbc, and also by temporarily putting the -P flag in
        Parrot/Test.pm and running all the tests. So, this code is as
        correct as the test suite can detect.

        Here's how it plays out in the code:

          * New script ops2c-prederef.pl

            Copy-paste code reuse from ops2c.pl. Modified to expect the
        args to give
            a void ** cur_opcode and to return a void **.

          * Modified ops2c.pl

              * opfuncs are now static. Who needs to call them by name from
        outside,
                anyway? They are accessed via the opfunc table.

              * Some MACRO stuff to make things work whether we prederef or
        not. It
                may be possible to get rid of these some day if other folks
        agree
                that we should be using CODE object pointers + offsets as
        our PC
                rather than raw pointers to either opcode_t's or (void *)'s
                (depending on prederef mode or no).

          * core.ops modified to be usable to build both kinds of opfuncs.
        For now,
            this means:

              * calls to push_generic_entry(... cur_opcode ...) were
        changed to
                push_generic_entry(... CUR_OPCODE ...), where CUR_OPCODE is
        a
                macro that does the right thing in both kinds of ops.c
        files.

                This is applicable to the bsr op. If we treated
        destinations as
                (Code PMC + local offset) rather than as
        pointer-to-memory-somewhere,
                this wouldn't be a big deal. We may need to do that at some
        point
                anyway, so that when you jump around and return not only do
        you have
                the right PC (pointer, today), but you also have the
        thread/interpreter
                knowing what chunk of bytecode it is in at all times
        (assuming we'll
                allow reflection, as in ops that query or affect the
        current CODE PMC).

              * runinterp was modified. Instead of copying the top-level
        PackFile struct
                and blasting its byte_code pointer, we simply call runops
        on the new
                interp, passing in the pointer to the current interp's code
        and the
                offset into that code at which to start (this last arg used
        to be a
                pointer PC, now its an offset PC).

          * include/parrot/op.h

              * new typedef for prederef opfuncs (they return void **)

          * include/parrot/interp_guts.h

              * New DO_OP_PREDEREF() macro described above.

          * include/parrot/interpreter.h

              * New prototype of runops() -- see below.

              * resume_addr field changed to resume_flag and resume_offset
        pair of fields.
                We might be resuming from interp using prederef to one not
        or vice-versa,
                so pointers between the two don't play nice together.
        Offsets are beautiful.

              * New PARROT_PREDEREF_FLAG constant

          * interpreter.c

              * include "parrot/oplib/core_ops_prederef.h"

              * prederef() function described above.

              * runops_prederef() runops variant. Uses DO_OP_PREDEREF()
        macro as its core.

              * runops() modified to take size_t CODE-relative offset PC
        rather than
                pointer PC. This made other things workable and doesn't
        seem to have lost
                anything important (IMO).

          * test_main.c

              * New flag '-P' to enable predereferencing.

          * Makefile modified to build core_ops_prederef.c from core.ops
        via
            ops2c-prederef.pl.

            BTW, also added missing $(INC)/interp_guts.h to H_FILES.

            Added core_ops_prederef$(O) to O_FILES

        * languages/miniperl/t/001_basic/basic1.scheme: Bogus entry

2001-12-12 16:22  jgoff

        * MANIFEST: Manifest additions for languages/miniperl

2001-12-12 16:19  jgoff

        * languages/miniperl/t/001_basic/: basic.t, basic1.scheme: Basic
        tests. These are left over from the Scheme suite and shouldn't be
        used yet.

2001-12-12 16:18  jgoff

        * languages/miniperl/: Miniperl/Generator.pm, Miniperl/Parser.pm,
        Miniperl/Test.pm, Miniperl/Tokenizer.pm, t/harness: Miniperl base
        modules. Miniperl/ is where the real work gets done.  t/ is largely
        vacant because it isn't ready to survive real tests yet.

2001-12-12 16:17  jgoff

        * languages/miniperl/: Makefile, Miniperl.pm, foo.mpl, miniperlc,
        mpc: Final go-round, hopefully.

        languages/miniperl/Makefile - Used basically to run tests, as there
        is nothing                               here that needs to be
        dynamically built.  languages/miniperl/Miniperl.pm - Stub module
        that calls the real Miniperl/ mods languages/miniperl/foo.mpl -
        Sample miniperl file.  languages/miniperl/miniperlc - Miniperl
        compiler stub

2001-12-12 16:09  dan

        * Configure.pl: Setting a variable with the make command name is
        useful.

2001-12-12 15:07  simon

        * Makefile.in, languages/jako/Makefile, languages/scheme/Makefile:
        Recursive make considered "ow, don't do that".

2001-12-12 14:45  dan

        * Makefile.in: Makefile had some non-portable code. (Okay, a lot of
        non-portable code) Killing builds on Win32 native. Small patch
        applied which hopefully fixes it.

2001-12-12 06:12  ajgough

        * classes/Makefile.in: perl is $(PERL), you know it makes sense.

2001-12-12 06:08  ajgough

        * Makefile.in: perl is $(PERL).

2001-12-12 06:00  ajgough

        * t/op/integer.t: Added tests to integer.t so that all permutations
        of arguments are actually called at some point.

2001-12-12 05:18  ajgough

        * t/op/time.t: I can't sleep, but I don't see why parrot shouldn't.
         Tests for sleep i|ic

2001-12-12 05:09  ajgough

        * t/op/stacks.t: Added pushp and popp register stack tests.

2001-12-12 04:51  ajgough

        * t/op/stacks.t: Added tests for save and restore, for all register
        types.  Let there be Haiku.

2001-12-12 04:27  ajgough

        * t/op/basic.t: bsr_i test.  You know you want it.

2001-12-12 02:55  ajgough

        * MANIFEST: Added hints/os2.pl to MANIFEST.

2001-12-12 02:52  jgoff

        * core.ops, key.c: Final checkin... These are actually the correct
        copies.

2001-12-12 02:12  jgoff

        * include/parrot/key.h: key.c - Removed a few functions,
        generalized set_element_value and element_value         to accept
        KEY_PAIRs from core.ops include/parrot/key.h - Modified header.
        core.ops - Modified to accept the new return style.

        This is a prelude to adding virtual-table methods to allow hashing
        &c. Expect at least one or two more redesigns before this settles
        down. However, it still passes the original tests.

2001-12-11 13:35  gregor

        * runops_cores.c:
        Fixed a typo.

2001-12-11 12:03  gregor

        * .cvsignore:
        Don't ignore test_prog, but do ignore parrot.

2001-12-11 12:03  gregor

        * classes/.cvsignore:
        Ignore the generated file default.h

2001-12-11 04:07  jgoff

        * key.c: Key source

2001-12-11 04:05  jgoff

        * include/parrot/key.h, t/op/key.t: Needed header file, new test

2001-12-11 04:00  jgoff

        * core.ops: Added new key aggregate operations to core ops.

2001-12-11 04:00  jgoff

        * include/parrot/parrot.h: Added key.h to header list

2001-12-11 03:59  jgoff

        * MANIFEST: Added key.c, include/parrot/key.h, t/op/key.t

2001-12-11 03:58  jgoff

        * Makefile.in: Added implementation of key aggregates.

2001-12-08 23:07  simon

        * README:
        README good to go.

2001-12-08 23:05  simon

        * Configure.pl, Makefile.in, README, Parrot/Test.pm,
        docs/intro.pod, languages/jako/Makefile, languages/scheme/Makefile,
        languages/scheme/Scheme/Test.pm, lib/Parrot/Test.pm:
        test_prog? What is test_prog?

2001-12-08 22:57  simon

        * ChangeLog:

        Oops, the changelog commit was on *this* machine.

2001-12-08 22:56  simon

        * NEWS:
        Updates to NEWS and ChangeLog pre-release.

2001-12-08 22:07  simon

        * MANIFEST, Makefile.in, classes/Makefile.in, classes/default.pmc,
        classes/perlnum.pmc, classes/pmc2c.pl:
        Add "default" PMC vtable so you can inherit implied stuff.

2001-12-08 21:24  simon

        * Parrot/PackFile.pm, docs/parrot.pod, docs/parrotbyte.pod,
        docs/vtables.pod, lib/Parrot/PackFile.pm:
        Getting the documentation up to scratch.

2001-12-08 21:21  simon

        * classes/pmc2c.pl:
        Allow inheriting from default class.

2001-12-07 20:43  gregor

        * examples/assembly/queens.pasm:
        Regenerated the file with the latest jakoc.

2001-12-07 20:29  simon

        * core.ops, t/op/stacks.t:
        Rename "rotate" to "rotate_up".

2001-12-07 20:15  simon

        * t/op/stacks.t:
        Some tests for rotate.

2001-12-07 00:55  gregor

        * core.ops:
        Cast the result of the pointer arithmetic, since without the cast
        there are warnings with some compilers, and without the parens
        around the pointer arithmetic, precedence breaks the meaning and
        causes crashes.

2001-12-06 23:37  simon

        * core.ops:
        Temporary. I prefer compiler warnings to segfaults, thanks.

2001-12-06 23:34  simon

        * runops_cores.c:
        Make "trace" work again.

2001-12-06 21:23  dan

        * Parrot/Test.pm, lib/Parrot/Test.pm: Undo twiddles to test.pm

2001-12-06 21:22  dan

        * core.ops, packfile.c, Parrot/Test.pm, include/parrot/stacks.h,
        lib/Parrot/Test.pm: Fix up source issues that made Dec C unhappy

2001-12-06 19:22  simon

        * core.ops:
        Yet another "How the *%$! did that compile?" moment.

2001-12-06 18:28  dan

        * hints/vms.pl: Fix to build, with a HERE logical required

2001-12-06 17:48  dan

        * core.ops, interpreter.c, pbc2c.pl, pdump.c, test_main.c,
        docs/parrot_assembly.pod, include/parrot/interpreter.h: Sensible
        changes to the interpreter--flags are now part of the interp
        structure.

        * docs/intro.pod:
        s/little_languages/languages/ in Jako section.

2001-12-06 13:15  simon

        * Makefile.in:
        Ensure the documentation gets made.

2001-12-06 13:12  simon

        * MANIFEST, docs/intro.pod:
        Documentation! Added the "Some Assembly Required" article with
        minor updates.

2001-12-06 00:39  simon

        * core.ops:
        More "eq" support.

        Courtesy of: Nguon Hao Ching <hao@netaxs.com>

2001-12-06 00:37  simon

        * test_main.c:
        Add the "-d" debug flag. Doesn't actually *do* anything yet.

        Courtesy of: Melvin <mrjoltcola@mindspring.com>

2001-12-06 00:11  tom

        * string.c, chartypes/unicode.c, chartypes/usascii.c,
        encodings/singlebyte.c, encodings/utf16.c, encodings/utf8.c,
        include/parrot/chartype.h, include/parrot/encoding.h,
        include/parrot/parrot.h: Moved string to number conversion code out
        of the encoding layer and into the main string layer as neither the
        encoding layer nor the character type layer knows enough on it's
        own to do the conversion correctly.

2001-12-05 23:12  tom

        * Makefile.in: Rebuild the classes directory if any of the object
        files for the classes are missing rather than only when perlint.o
        is missing.

2001-12-05 19:43  gregor

        * Parrot/Assembler.pm, lib/Parrot/Assembler.pm:
          * Reworked the constantize_string() stuff a little bit because it
        was
            puking on things like "\033[H\033[2J\0" (which occurs in the
            languages/jako/mandelzoom.jako example).

2001-12-05 19:39  gregor

        * languages/jako/: Makefile, mandelzoom.jako:
        Added 'mandelzoom' example.

2001-12-05 19:38  gregor

        * languages/jako/jakoc:
          * Added sleep()

          * Changed some instances of die() to confess()

2001-12-05 18:34  gregor

        * t/: op/pmc.t, pmc/pmc.t:
        s/sting->int/string->int/

2001-12-05 18:08  gregor

        * Parrot/.cvsignore:
        Ignore PMC.pm

2001-12-05 18:05  gregor

        * classes/.cvsignore:
        Ignore the generated files.

2001-12-05 17:19  gregor

        * pbc2c.pl:
          * Reverted recent changes, since they broke the script. Real fix
        coming
            later.

2001-12-05 17:03  simon

        * classes/Makefile.in:
        Remember: change Makefile.in, not Makefile. D'oh.

2001-12-05 17:02  simon

        * Makefile.in:
        Ensure PMC.pm gets remade.

2001-12-05 16:58  simon

        * MANIFEST, Makefile.in, classes/Makefile.in,
        classes/perlundef.pmc, include/parrot/pmc.h:
        Add perlundef class.

2001-12-05 16:45  simon

        * core.ops:
        Document "new P0, foo"

2001-12-05 16:43  simon

        * MANIFEST, Makefile.in, pbc2c.pl, pmc_pm.pl, Parrot/Assembler.pm,
        lib/Parrot/Assembler.pm, t/op/pmc.t, t/pmc/pmc.t:
        Allow assembler to know about PMC class names.

2001-12-04 13:39  ajgough

        * MANIFEST: Added t/op/pmc.t to MANIFEST.

2001-12-04 05:02  ajgough

        * classes/perlnum.pmc: Picky compiler pointed out probable thinko
        in perlnum.c

2001-12-04 04:24  ajgough

        * encodings/singlebyte.c, t/op/pmc.t, t/pmc/pmc.t: A much less
        broken form of strtod and appropriate tests.  Does not yet check
        for overflow.

2001-12-04 01:31  ajgough

        * string.c, encodings/singlebyte.c, encodings/utf16.c,
        encodings/utf8.c, include/parrot/encoding.h: Added length parameter
        to extract_num and extract_int string vtables, without this it
        would be impossible to have strings with nulls in while still
        knowing where they ended.

2001-12-03 18:40  ajgough

        * string.c, classes/perlstring.pmc, encodings/singlebyte.c,
        encodings/utf16.c, encodings/utf8.c, include/parrot/encoding.h,
        include/parrot/string.h: Moved pmc string to number conversion into
        the string encoding tables.

2001-12-03 00:21  ajgough

        * core.ops, t/op/pmc.t, t/pmc/pmc.t: Added set i, p and some tests
        for p-> integer.

2001-12-02 23:09  jgoff

        * classes/Makefile.in: Removed some redundant targets.

2001-12-02 19:02  ajgough

        * t/: op/pmc.t, pmc/pmc.t: Modified all pmc tests to make use of fp
        equality macro rather than using perl to generate expected output,
        all tests now have <<OUTPUT.

2001-12-02 17:44  ajgough

        * t/op/trans.t: Upgraded fp_eq and fp_ne macros to be more useful
        for pmc.t as well.  Will probably move macros into another file at
        some point, although this might be best left until the tests are
        unperled.

2001-12-02 06:16  jgoff

        * classes/pmc2c.pl: It wasn't properly setting the vtable index
        within Parrot_Perl{Class}_init.

2001-12-02 06:09  jgoff

        * classes/Makefile.in: I seem to have removed *$(O) twice..

2001-12-02 05:06  jgoff

        * Configure.pl, MANIFEST, Makefile.in: (Hopefully the last time...)
        Configure.pl - Removed '-I./include', added classes/Makefile
        generation MANIFEST     - Added classes/Makefile.in Makefile.in  -
        Removed old classes/* make stuff                Added target for
        classes/Makefile

2001-12-02 04:48  jgoff

        * classes/Makefile.in: Going to be used shortly...

2001-12-02 04:40  jgoff

        * docs/Makefile: Configure.pl - Added automatic makefile creation
        for docs/ and classes/                Removed '-I./include' because
        it was getting incorrectly                passed to classes/
        MANIFEST - added docs/Makefile.in, classes/Makefile.in Makefile.in
        - Removed classes/ build stuff, replaced with classes/Makefile.in
                    Added '-I./include' locally docs/Makefile - Should no
        longer be used, but I'm not brave enough to do a
        cvs delete.

2001-12-02 01:21  ajgough

        * t/op/trans.t: Refactored trans math tests to have hard coded
        expected return values and be more ready to be unperled at some
        point in the future.  Added $fp_equality_macro which is a
        "nearly-equal-to" function.

2001-12-02 01:18  ajgough

        * Makefile.in: Humph.  People really ought to use Makefile
        variables, s/perl/$(PERL)/ throughout.

2001-12-01 18:15  jgoff

        * classes/: perlint.pmc, perlnum.pmc: Temporary patch until we
        figure out what to do vis-a-vis the lack of snprintf.

2001-11-30 13:14  ajgough

        * t/op/: integer.t, number.t: Added tests for abs ops to number.t
        and integer.t

2001-11-30 13:14  ajgough

        * core.ops: Added abs(i|n, i|ic|n|nc) ops to core.ops, using if <0
        -, else ... form.

2001-11-30 10:36  simon

        * core.ops:
        Rewrite print_p to do the right thing.

2001-11-30 06:21  jgoff

        * t/: op/pmc.t, pmc/pmc.t: New tests for integer/number/string
        concat,               integer/number/string math

2001-11-30 06:20  jgoff

        * classes/: perlint.pmc, perlnum.pmc, perlstring.pmc:
        classes/perlint.pmc - Fixes and expanding for concat and math with
        strings classes/perlnum.pmc - Fixes and expanding for concat and
        math with strings classes/perlstring.pmc - Fixes and expanding for
        concat and math with strings

2001-11-29 15:21  ajgough

        * hints/os2.pl: This is a hints file for os/2, I've set $c{perl} as
        $^X lies, which confused bash which make uses to run things when
        doing its stuff.

2001-11-29 04:58  jgoff

        * classes/perlstring.pmc: Removed C++-style comments for good
        measure

2001-11-29 04:51  jgoff

        * t/: op/pmc.t, pmc/pmc.t: New tests for PMC integers

        * global_setup.c: Initialize PMC strings

2001-11-29 04:25  jgoff

        * core.ops: Added set_p_s and set_p_sc, modified print_p to handle
        string PMCs.

2001-11-29 04:24  jgoff

        * classes/: perlint.pmc, perlnum.pmc, perlstring.pmc: Changed PMC
        files to properly upgrade int to num, do calculations.  Also added
        basic string operations. Currently errors out on anything but set
        operations, but this will be fixed soon.

2001-11-29 04:22  jgoff

        * Makefile.in: PMC .c files weren't getting cleaned out.

2001-11-28 14:27  ajgough

        * t/op/string.t: test "null onto null" incorrectly passing as it
        produced no output.  Output provided.

2001-11-28 11:14  simon

        * include/parrot/pmc.h:

        * classes/perlint.pmc, classes/perlnum.pmc, t/op/pmc.t,

        assuming a single byte encoding.

        platforms/win32.c, platforms/win32.h:
        Patch from Jason Diamond to make win32 platform stuff work:

        * Modified Configure.pl, mswin32.pl, and Makefile.in so that the
        platform specific files in the platforms directory gets copied to
        the correct directories. The Makefile will re-copy the platform.h
        and .c files if the original is modified.

        * #include platform.h in parrot.h instead of time.h.

        * Removed time.h and time.obj from the Makefile. time.h and time.c
        aren't being used anymore since that code was moved to linux.c and
        win32.c.

        * Renamed the BOOL typedef in parrot.h to BOOLVAL (inspired by
        INTVAL and FLOATVAL). This was conflicting with the BOOL typedef in
        windows.h. This required updating several files besides parrot.h.

        * Added a DEFAULT_OPEN_MODE to linux.h and win32.h and used that
        instead of the missing identifiers (on Windows) in core.ops in the
        calls to open.

        * Added Parrot_sleep and Parrot_setenv to both the linux and win32
        platform files and called those from core.ops. The Linux code for
        these functions came from core.ops so they should hopefully work.

        * MANIFEST, Makefile.in, core.ops, obscure.ops, time.c,

        Initial "fix" of time(n) op for Win32:

          * Initial Win32 code Courtesy of Richard J Cox <rjcox@cix.co.uk>

          * time.c and include/parrot/time.h

            First attempt at getting this working across platforms. The
            macro WIN32 being tested might not be right.

          * New functions Parrot_intval_time() and Parrot_floatval_time()
            wrap the appropriate functionality depending upon platform.
            Changed core.ops to call these.

        Added obscure.ops with obscure transcendental ops.

        Added simple file I/O ops (close, open, read, write):

          * Initial versions Courtesy of Jeff <jgoff@speakeasy.net>

          * I changed some arg ordering stuff.

          * I added read/write of INTVALs and FLOATVALs.

        Added environment variable ops (getenv, setenv)

        Added system error ops (err(i) and err(s) for accessing errno and
        strerr().

        Moved print ops in with other "temporary" developer ops, since
        they'll move to a devel.ops or temp.ops oplib once we have oplibs.

2001-10-29 14:37  gregor

        * core.ops, languages/jako/jakoc:
          * New variants of the save ops to save constants on the stack.
        This is
            useful for saving zero arg and result counts on the stack, for
        example.

          * Modified jakoc to to adapt to the newly announced calling
        conventions.
            Even though Jako source code appears to show subroutines with
        fixed
            numbers of arguments and results, they are implemented with the
            variable count calling convention. Future modifications will be
        needed
            to ensure that an exception is raised if the stack frame is of
        the
            wrong size (or, at least that we pop the complete frame off).
        We'll
            also have to make more changes to support the true
        fixed-arg-count
            and fixed-result-count parts of the calling convention spec.

        deallocators in resources.c.

        Unfortunately we lost standalone string-test mode, but I can cope
        with that.

        Please note that until we have a real allocation/deallocation/GC
        system, this'll leak. A *lot*.

2001-10-21 15:20  gregor

        * examples/assembly/queens.pasm:
          * Modernize the calling conventions in queens.pasm. It was using
        swap,
            which now must be rotate. Also, changed to use return values on
        the
            stack instead of in I0.

2001-10-19 18:14  gregor

        * core.ops, stacks.c, include/parrot/stacks.h,
        languages/jako/jakoc:
        Per Dan's request, replacing 'swap' op by 'rotate'.

          * core.ops: Replaced 'swap()' by 'rotate(i|ic)'.

          * stacks.c and stacks.h: Removed swap-related functions from my
            prior commit, replacing them with stack_depth(), stack_entry()
            and rotate_entries().

            NOTE: The stack_depth() and rotate_entries() routines could
            be made more efficient through the caching of the sum of chunk
            'used' members from lower chunks in a field in the upper
            chunks. Also, if the interpreter's stack_base was changed to
            hold the pointer to the *top* chunk (since we usually come
            at the stack from the top down) instead of the *bottom*
            chunk. The code here at least works, and we can decide about
            bigger changes separately.

            For now, rotate only handles rotates in one direction and
            of magnituded one. A fully general rotate would do handle
            rotates in both directions and of arbitrary amounts. Again,
            this implementation is sufficient for current applications,
            and a feature-complete version can be developed if this turns
            out to be otherwise the right type of implementation.

            This change includes a new exception for ERROR_STACK_SHALLOW,
            meaning "not-empty-yet-not-deep-enough-for-what-you-asked".

          * jakoc: Changed the calling convention to use rotate instead
            of swap (of course). Also changed the convention for return
            value passing to use the stack as well.

        languages/jako/primes.jako, languages/jako/queens.jako,
        languages/jako/sub.jako:
          * New stack functions push_entry(), pop_entry() and swap_entry().
            The first two exist for the support of the last one. These
            functions don't care what is in the stack entries. These exist
            to support the new 'swap' op (see next bullet).

          * New op 'swap' for swapping the top two elements on the stack.
            This is necessary for passing arguments to functions, since
            the return address will be on top of any arguments that have
            been pushed on the stack. This way, you can use a (swap, pop)
            pair to retrieve each argument (for subroutine linkage).

          * Disassembler now prints numbers in decimal by default, with
            a new '-x' flag to turn on hexadecimal display. Since other
            members of the Parrot Tool Set use decimal by default, this
            makes it easier to compare output from the various tools.

          * Jako compiler has more explanatory comments and the following
            new features:

              * Lexically scoped variables.

              * Subroutines that take arguments and return values:

                  sub int foo(int bar) {
                    if (bar == 1) {
                      return 42;
                    } else {
                      return 13;
                    }
                  }
              * ... if (...) and ... unless (...) statement modifiers
                can be used on next, last and redo.

              * Bitwise and (&, &=) and or (|, |=) ops.

              * Type names are just 'int', 'num', 'str', and 'poly' now.
                The old long names 'integer', 'number', 'string', and
                'polytype' are no longer valid.

              * Integer variable assignments can now use 0b (binary),
                0 (octal) and 0x (hexadecimal) radix prefixes on literals.

          * New Jako and Parrot assembly examples queens.{jako,pasm} for
            solving the eight-queens problem. The assembly example is a
            hand-modified version of the assembly code produced by the
            Jako compiler from queens.jako. A few unnecessary ops have
            been removed, lots of unnecessary labels have been removed,
            and all the Jako source code comments have been removed.

          * Makefile and .cvsignore in languages/jako modified so that
            the assembler produces listings when assembling the programs,
            yet the *.list files are ignored by CVS.

          * Made the default target in languages/jako/Makefile 'all'.

          * Modified some of the Jako examples to use some of the new
            features of Jako, such as subroutines and lexical variable
            scoping.

        without also generating this unwanted version:

        one expanded argument and all the expanded arguments are constants.

        Moby Patch:

          * basic_opcodes.ops and opcode_table replaced by core.ops

          * process_opfunc.pl replaced by Parrot/OpsFile.pm, Parrot/Op.pm,
            and ops2c.pl. These convert *.ops to *_ops.c and
            include/parrot/oplib/*_ops.h

          * New ops2pm.pl converts *.ops to Parrot/OpLib/*.pm

          * disassemble.pl modified to use

          * interpreter.c modified to use structures in core_ops.c instead
            of the old op_info and op_func stuff. We're not yet to the
            point of handling multiple oplibs at a time, but we are getting
            there...

            Fingerprinting stuff disabled for now. We used to go off
            opcode_table. We need to rethink this. I have some ideas to
            make it unnecessary, but it remains to be seen whether others
            will like the direction they take us.

            Termination condition for while(){} loop in runops is now
            (pc) instead of (*pc). Any op can cause a HALT by returning
            a NULL pointer. Ops end, bounds and trace all do this. So, now
            the 'end' op body is actually executed, although all it does
            is HALT.

          * Makefile.in modified to perform a test build using pbc2c.pl,
            which is the bytecode --> C compiler I've posted to the
            list before.

          * Op full names are now autogenerated. Op root names must not
            contain underscores, so some op renamings have happened.
            Such as clear_i becoming cleari.

2001-10-08 14:45  gregor

        * basic_opcodes.ops, opcode_table, t/op/integer.t, t/op/number.t:
        Arithmetic enhancements:

          * Renamed existing mod_i as cmod_i and added "corrected" mod_i:

            NOTE: This "uncorrected mod" algorithm uses the C language's
        built-in
            mod operator (x % y), which is

                ... the remainder when x is divided by y, and thus is zero
        when y
                divides x exactly.
                ...
                The direction of truncation for / and teh sign of the
        result for %
                are machine-dependent for negative operands, as is the
        action taken
                on overflow or underflow.
                                                                     --
        [1], page 41

            Also:

                ... if the second operand is 0, the result is undefined.
        Otherwise, it
                is always true that (a/b)*b + a%b is equal to z. I both
        operands are
                non-negative, then teh remainder is non-negative and
        smaller than the
                divisor; if not, it is guaranteed only that the absolute
        value of the
                remainder is smaller than the absolute value of the
        divisor.
                                                                     --
        [1], page 205

            This op is provided for those who need it (such as
        speed-sensitive
            applications with heavy use of mod, but using it only with
        positive
            arguments), but a more mathematically useful numeric mod based
        on
            floor(x/y) and defined with y == 0 is provided by the mod_i op.

              [1] Brian W. Kernighan and Dennis M. Ritchie, *The C
        Programming
                  Language*, Second Edition. Prentice Hall, 1988.

          * Added "corrected" mod_i:

            NOTE: This "corrected mod" algorithm is based on the C code on
        page 70
            of [1]. Assuming correct behavior of C's built-in mod operator
        (%) with
            positive arguments, this algorithm implements a mathematically
        convenient
            version of mod, defined thus:

              x mod y = x - y * floor(x / y)

            For more information on this definition of mod, see section 3.4
        of [2],
            pages 81-85.

          * Added mod_n, using the same formula as above, but with FLOATVAL
            arguments.

          * Added cmod_n, using the C math library's fmod() function:

            NOTE: This "uncorrected mod" algorithm uses the built-in C math
        library's
            fmod() function, which computes

                ... the remainder of dividing x by y. The return value is x
        - n * y,
                where n is the quotient of x / y, rounded towards zero to
        an
                integer.
                                                -- fmod() manpage on RedHat
        Linux 7.0

            In addition, fmod() returns

                the remainder, unless y is zero, when the function fails
        and errno
                is set.

            According to page 251 of [1], the result when y is zero is
        implementation-
            defined.

            This op is provided for those who need it, but a more
        mathematically
            useful numeric mod based on floor(x/y) instead of truncate(x/y)
        and
            defined with y == 0 is provided by the mod_n op.

        * basic_opcodes.ops, interpreter.c, opcode_table,
        process_opfunc.pl, test_main.c, include/parrot/interpreter.h,
        t/trace.pasm:
          * Two new ops, trace_ic and bounds_ic that twiddle bits in
            interpreter->flags and set interpreter->resume_addr.

          * Two new runops core variants, so now we cover the relevant
            flag space over {trace, notrace} x {boundscheck, noboundscheck}

          * Runops core selection that converts the flags into an index
        into
            a core table (runops_cores) to get the core function pointer.

          * A new trace_op variant that doesn't do bounds checking (used by
            the non-bounds-checking-but-tracing runops core).

          * PC is passed into the cores so that they can be used when
            resuming (they used to assume starting at the beginning of the
            code, which would thwart resumption).

          * runops() itself is changed to have a while() loop in it so that
            any time we drop out of the core, we'll resume if we have an
            interpreter->resume_addr set (after reselecting the core,
        though).

          * process_opfunc.pl has a new "macro": RESUME(), that sets up
            interpreter->resume_addr. This is used by the new ops. The new
            ops still return the new PC as the next op (which MUST be an
            'end' op to force the core loop to terminate -- *pc being false
            is the only termination condition we can count on for all
        cores).

          * New interpreter flag: PARROT_BOUNDS_FLAG, used to control
            bounds checking core selection.

          * test_prog now has a '-b' flag in addition to the '-t' flag.
        Now,
            bounds checking is off by default (I saw a performance boost:
            6.3 Mop/s with -b, 7.0 Mop/s without).

          * A new sample/test program: t/trace.pasm that twiddles the trace
            flag while it is running.

        * .cvsignore, Makefile.in, build_interp_starter.pl, interpreter.c,
        include/parrot/.cvsignore, include/parrot/interpreter.h:
        Now that 0.0.2 is released, I can clear out the backlog of approved
        but uncommitted patches. Here's one Dan approved on 2001-09-21
        (Simplified DO_OP):

          * test_prog and pdump are linked with only the files the need,
        not
            al the files.

          * build_interp_starter.pl writes out op_info.[hc], too. These
        files
            contain op name, arg count and arg type information. This will
        be
            useful for multiple things in the future, including better
        trace
            output and the crystalizing loader.

          * The DO_OP macro is now simpler and doesn't require explicit
            temporaries.

          * interpreter.c is modified to use the new op info in tracing
        output.

          * The interpreter just points its opcode_funcs and opcode_info
            members at the default tables rather than allocating memory on
            the fly.

        memory.c, packfile.c, process_opfunc.pl, strnative.c, test_main.c:
        This patch ensures that all bytecode is of type opcode_t except for
        the constant table constants.  That means that almost all of the
        INTVALs in the code were replaced with opcode_t and the i pack type
        was replaced with the op pack type in calls to pack_arg and such.
        Also, since it has been declared that ALL integer constants are to
        be 32 bits, some test cases were changed to ensure that an integer
        constant was no bigger than 2 ** 31.

        process_opfunc.pl was also cleaned up to no longer look at either
        opcode_table or interp_guts.h but gather all of its information
        from Opcode.pm.

        The Assembler.pm module was changed to do late binding of arguments
        so that 0 could be treated like 0.0 without having to be so
        declared.  Also, only strings now use the [sc:N] intermediate form
        as it was unnecessary for integer and float types.

        t/local_label.pasm, t/test.pasm, t/test2.pasm, t/test3.pasm,
        t/op/basic.t:
          * Added new syntax to the assembler to allow square-bracket
            arithmetic expressions involving (global) labels, the current
            instructions base address ('@'), numeric constants (not
        equates)
            and basic arithmetic operators (+, -, *, / -- although + and -
            are likely to be the only ones used in practice).

          * Fixed a bug in Parrot/Assemble.pl that caused macro expansion
        to
            fail (argument passing wasn't working).

          * Enabled t/op/basic.t's last test, which is actually a copy of
        the
            code from t/call.pasm. Now all tests there are enabled and
        working.

          * Added new example/test program t/call.pasm to demonstrate
        working
            macros and poor-man's subroutine calls

          * Added header comments to t/*.pasm

        include/parrot/packfile.h, include/parrot/string.h:
        Move NVs to the constant table.    * Changes to Types_pm.in to make
        life easier for some of the      packing/etc. I'm doing elsewhere.
        Also, we now pack 'n' as      'i'.

          * Moved the guts of assemble.pl to Parrot/Assembler.pm so that
            eventually we can use all these tools together inside scripts
            rather than call out to the shell to run the programs.

          * As I was tracking down problems, I converted the internal
            documentation of the assembler to POD from comments.

          * Changed the numeric regexp in the assembler to detect leading
            signs and trailing exponents.

          * Updated basic_opcodes.ops to fetch numeric constants from the
            constant table.

          * Enhanced the disassembler in a number of ways to make my life
            easier while tracking down bugs (try it out). It now puts in
            labels for ops that are the destinations of flow control ops.

          * packfile.c now has a TRACE_PACKFILE switch that can be set
            to get it to print info as it processes. I needed this while
            debugging, but I can remove it or change it before committing
            if its a problem.

          * Updated pdump.c because it was missing a call to init_world().

          * Updated process_opfunc.pl to deal with numeric constants
            being stored in the constant table instead of inline.

          * Added multiple type support to Parrot/PackFile/Constant.pm

          * Added Parrot/String.pm, to be used for constants.

          * Added packfile.[hc] functions for allocating new constants
            of various types.

          * Made string_copy visible to the world in parrot/string.h.

        Wow.

        * assemble.pl: This patch makes integer constants of the form
        0b[01]+ work with perl 5.005.  The oct function in versions of perl
        before 5.6 did not handle the 0b numeric prefix; therefore, it was
        returning 0.  To fix this, I added a from_binary function that
        would take a binary string and return its decimal representation.
        Now, instead of blindly calilng oct, it makes a distinction between
        0/0x numbers and 0b numbers.

          * bytecode.[hc] removed. packfile.[hc] are the interface to the
            packfile/bytecode file from C. May be renamed in the future.

          * packfile.[hc] changed to use 'struct PackFile *', etc. instead
            of 'PackFile *', just like the interpreter, etc.

          * Constants are accessed via the interpreter's 'code' member
            (struct PackFile * code). Macros PCONST(i) and PNCONST are
            provided to access constants by index and the number of
            constants, respectively (assumes a variable 'interpreter' of
            the appropriate type is in scope).

          * Byte Code is accessed via the interpreter's 'code' member.

          * Changed PackFile_Constant to point to a STRING instead of
        having
            members for the string_make() arguments. Also has a 'type' IV
            in preparation for allowing multiple types of constants in
            const_table.

          * Removed hardcoded example program from test_main.c. We have
            plenty of test programs elsewhere.

          * test_prog now uses a PackFile to deal with the program before
            sending it on to the interpreter.

          * Added missing 'end' ops to some tests in t/op/integer.t and
            t/op/stacks.t.

        * Parrot/Opcode.pm, Parrot/Test.pm, lib/Parrot/Opcode.pm,
        lib/Parrot/Test.pm:
        This patch does two only somewhat related things.

        Parrot/Opcode.pm:  Change the hard-wired assumption that sizeof(nv)
        = 2*sizeof(iv) to a PConfig-type computed value.

        Parrot/Test.pm:  Change it to run with the perl that was used to
        generate this version of Parrot.  This is useful if, for example,
        you want to use bleadperl to build and test parrot (e.g. to try out
        various 64-bit options) but you still have a 5.6.x (or 5.005_xx)
        installed as the default 'perl' on your system.  Since perl-5.7.x
        is installed 'version-only', a plain 'perl' is quite likely to pick
        up the older perl in such cases. Such an older perl might well not
        understand pack('q') used in the assembler.

        * t/op/integer.t, t/op/number.t, assemble.pl, opcode_table: Fixed
        opcode_table listing of if_i_ic and if_n_ic.  Dan had changed the
        function to only use 2 args, but the opcode_table still had three
        listed.  Fixed integer.t and number.t to use the new comparison
        operators.  Improved assemble.pl ability to grok operators by
        constructing a function set and comparing operator types.

2001-09-19 22:42  dan

        * assemble.pl: Binmodes the output filehandles now. (No more
        bytecode munching...)

        * Configure.pl, basic_opcodes.ops, opcode_table, process_opfunc.pl,
        t/euclid.pasm, t/test.pasm, t/test2.pasm: Changed opcodes so
        conditional branches take a single argument, and fall through
        otherwise.

2001-09-19 20:04  thgibbs

        * assemble.pl: Modifications to run on 64 bit platforms.  To run on
        a 64 bit platform manually change the  setting for 'i' from 'l' to

        the near future.

          * C code for dealing with PackFiles as if they were objects.
        Mostly
            read-only interface for now, but it would not be hard to make
        it
            read-write. [packfile.c, include/parrot/packfile.h]

          * PackFile Dumping program that falls short of disassembling, but
            tests the above code and provides a hex listing of the byte
        code
            contents of the PackFile. [pdump.c]

          * New Makefile target 'pdump' for the above program, and related
            Makefile.in changes.

        lib/Parrot/PackFile/Constant.pm, lib/Parrot/PackFile/FixupTable.pm:

        Functions for reading, writing and manipulating Parrot Pack Files.
        NOTE: This is a proposed term based on the fact that the file
        contains more than just byte code, and another language (Java)
        calls its binary files by a broader notion of what's in them (Class
        Files). Since Perl has packages, and since we use pack() to write
        them, we'll call them PackFiles (at least for now).

        That does, however, beg the question of file extension. Should we
        name the files "foo.pack" instead of "foo.pbc"?

        * build_interp_starter.pl, bytecode.c, bytecode.h, interpreter.c,
        interpreter.h, test_main.c:
          * Provides macros in interp_guts.h for setting up arrays with
            op names and op arg counts (done via build_interp_starter.pl).

            These are used in the op tracing

          * The functions in bytecode.[hc] pass around a pointer to the
        length
            of the bytecode so that later when we get to runops, we know
            how much bytecode we've got and we can detect out-of-bounds
            jumping. The documentation is updated, too.

          * runops in interpreter.c now looks at interpreter->flags to
            decide if the core of runops should be runops_trace_core or
            runops_notrace_core. These new functions contain just the
            while-loop portion of runops. A new function runops_generic
            does any other setup (such as checking the bytecode
            fingerprint) or wrapup (such as complaining if we ended up
            out-of-bounds). NOTE: I didn't know what we should do for
            functions in here that are not part of the api, so I gave
            them docs with 'TODO' marks mentioning they really aren't
            part of the api. Guidance appreciated.

          * test_main.c now checks for '-t' arg and sets the tracing flag
            on its interpreter instance as appropriate.

2001-09-17 17:47  bdwheele

        This will allow the compiler to emit code that works when the
        constant-comparison ops are backed out of Parrot. If the ops ever
        make their way back in, then jakoc can emit more efficient code
        again.

        * languages/jako/Makefile:

        compile.

2001-09-15 21:58  gregor

        * languages/jako/: jako_compiler.pl, jakoc:

        Jako Compiler:   * fix a bug in assignment handling   * add some
        more conditionals to while and if   * revert to using implicit
        opcodes in a few cases that were broken     before the assembler
        patch went in recently.

        From Brian Wheeler:

        This patch gives the assembler support of '\a','\n','\r','\t', and
        '\\' in string constants.

        In addition, it changes (for all registers) "I reg %li is ..." to
        just the value of the register.  Printing constants is also
        supported, but alas, you have to specify the type (print_sc,
        print_ic, print_nc).

        * Makefile, assemble.pl, bytecode.c, disassemble.pl,
        make_op_header.pl, opcode_table, process_opfunc.pl:
        Brian Wheeler's big patch:

        * Changes the opcode_table file to provide additional information
        about the operands.  Case shouldn't be a problem since that data
        never becomes a C symbol [this is pretty much as before]

        * Padding errors solved:  assemble.pl and bytecode.c were padding
        the constants incorrectly.  It should have been 4-(size % 4), not
        just (size % 4).  It is now fixed in both places.

        * assembler has less special cases, and should be easier to hang
        error checking on

        * disassembler dumps constant table and the format is a bit
        prettier, including register names, etc.

2001-09-11 23:21  dan

        * Makefile, assemble.pl, global_setup.h, interpreter.c,
        interpreter.h, opcode_table, parrot.h, test.pasm: (Here's hoping
        this takes) Added global_setup.h to declare init_world function

        Moved variable declarations out of the interpreter loop for small
        speed boost.

        Changed end opcode to now be opcode #0. A function is provided for
        it, but isn't ever executed.

        When the interpreter sees an opcode 0 in the stream it means the
        end of stream. Things were coring on Cygwin otherwise. (I think I
        was dereferencing a zero, which is bad)

2001-09-06 22:07  dan

        test_opcodes.c is now irrelevant--they're all in basic_opcodes.ops.

        basic_opcodes.c is now autogenerated from basic_opcodes.ops, and
        should be nuked. So it is. :)

        * basic_opcodes.ops, build_interp_starter.pl, process_opfunc.pl:
        Scripts to build the header file that holds the function table
        creation code, as well as the script to turn an opcode file to C
        source. (And the basic opcode functions turned into an opcode
        source file)

2001-09-06 03:31  dan

        * Makefile, interpreter.c:
        Changes to support the autogeneration of the opcode function
        pointer table in interpreter.c, along with the changes to the
        Makefile needed.

        * bytecode.c, config.h, docs/opcodes.pod, docs/overview.pod,
        docs/parrotbyte.pod, docs/vtables.pod:
        Added stubs for the documents; working on them this week. (What's
        left of it.) config.h change is just to type VTABLE, and the
        bytecode thing you might want to revoke. It's apidoc for the
        functions in there.

        * docs/strings.pod:
        A start on the string API documentation.

        * opcode_table:
        Since we specify the opcode number, we can rearrange to a more
        human-friendly ordering.

2001-09-03 17:42  simon

        * basic_opcodes.c:
        Coupl'a logic bugs. (I think)

2001-09-03 17:41  simon

        * string.c, string.h, strnative.c:
        Tidying up the string vtables.

2001-09-03 17:38  simon

        * make_op_header.pl:
        Spit out the whole of op.h, not just the bit in the middle.

        * README: it seems like we indeed can commit. What about sending
        commit mails?

         I'm still working on the string stuff, though.
