* mini.c (mono_method_to_ir): It turns out that some of the

[mono-project.git] / mono / mini / ChangeLog

2004-12-21  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (mono_method_to_ir): It turns out that some of the
        x-appdomain wrappers are lax with types, so just ignore this for
        all wrappers.

        * inssel.brg (OP_CHECK_ARRAY_TYPE): Optimize this by only looking
        at the vtable->klass. If it is non-shared code we can just use the
        vtable.

Tue Dec 21 17:43:06 CET 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c: access MonoDomain from tls, too.

2004-12-21  Sebastien Pouliot  <sebastien@ximian.com>

        * declsec.c: Removed unused variable (and related warning ;-)

2004-12-21  Ben Maurer  <bmaurer@ximian.com>

        * iltests.il: New test for LDELEMA on an array of ref types.

        * mini.c (CEE_LDELEMA): We need to emit OP_CHECK_ARRAY_TYPE for
        all ldelema's on reftypes.
        (check_call_signature): Remove the OP_CHECK_ARRAY_TYPE from here,
        it was the wrong place to put it.

        * mini-x86.c (mono_arch_output_basic_block): Just use ecx as the
        register to pop to make this cleaner, at the request of Paolo.

2004-12-20  Ben Maurer  <bmaurer@ximian.com>

        * mini-ops.h (OP_GETHASHCODE): New op.

        * inssel.brg (OP_GETHASHCODE): Emit code for the new opcode

        * mini.c (mini_get_inst_for_method): Create the intrinsic hash
        operation.

        For a microbenchmark, this reduces the cost of Hashtable.get_Item
        by 25%.
        
        * mini-x86.c (mono_arch_output_basic_block): Rather than

        add ebp, 4

        Emit

        pop edx

        The first is 3 bytes while the second is 1. This saves 36 kb on
        mscorlib, quite a big saving. When bootstraping mcs, I was able to
        see a small boost because of icache locality.

        * cfold.c (FOLD_BINOPCOMM): Kill add foo, 0

Mon Dec 20 12:19:40 EST 2004 Paolo Molaro <lupus@ximian.com>

        * Makefile.am, mini-ppc.h, mini-exceptions.c, exceptions-ppc.c:
        started code sharing with the generic code.

Mon Dec 20 11:08:06 EST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: added code for direct access to
        tls data slots.

Mon Dec 20 10:58:28 EST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ops.h, inssel-x86.brg, cpu-amd64.md, inssel.brg, inssel-amd64.brg,
         mini-amd64.c, mini-x86.c, cpu-pentium.md: renamed OP_X86_TLS_GET
        to OP_TLS_GET.

2004-12-20  Sebastien Pouliot  <sebastien@ximian.com>

        * declsec.c|h: Added functions to cache the declarative stack modifiers
        in MonoJitInfo and to create a security frame from a MonoJitInfo 
        structure.
        * mini.c: Initialize jinfo->cas_inited to FALSE when MonoJitInfo is
        created. Register internal calls for System.Security.SecurityFrame::
        _GetSecurityFrame and _GetSecurityStack.
        * mini.h: Added definition for new icalls (in mini-exceptions.c) and
        the definitions for the new stack walk/callback mechanism.
        * mini-exceptions.c: Added internal call GetSecurityFrame (to get the 
        first security frame for LinkDemands and InheritanceDemands) and
        GetSecurityStack for Demands. Both use the new mono_walk_stack code
        from lupus.
        * mini-x86.h, mini-amd64.h, mini-sparc.h: Architecture specific stack
        walk initialization (lupus).

2004-12-20  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_DUP, handle the dup / stloc
        idiom.
        (handle_loaded_temps): Do not create a temporary variable for
        things that we know are temps. They will never be modified.
        (mono_spill_call): Set MONO_INST_IS_TEMP
        (mono_emulate_opcode): ditto
        (emit_tree): ditto
        (mono_method_to_ir.CEE_DUP): ditto

2004-12-19  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (type_to_eval_stack_type): Make this handle the void type
        (mono_emit_call_args): set the call->type with type_to_eval_stack_type
        (emit_tree): use ip_in_bb to special case some common idioms
        Update all callers to pass in the IP.
        (mono_method_to_ir): Make CEE_CALL* do the above as well.

        This gives us a nice 2% speedup in mcs bootstrap.

        * mini-x86.c (peephole_pass): Peephole pass to make
        mov  [foo], eax
        push [foo]

        into

        mov [foo], eax
        push eax

        * mini.c (ip_in_bb): new method.
        (mono_method_to_ir): use this method rather than doing the hash
        lookup ourselves.

        * linear-scan.c (mono_linear_scan): When expiring actives, you
        don't need to keep around variables that expire on this
        instruction. This makes it so that:
             a = b + 1
        will turn into:
             store (ebx add (ebx, 1))
        which will become
             add ebx, 1

2004-12-19  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Optimize the common ldobj+stloc

        changes from the x86 code.

        * mini.h: Add prototype for mono_arch_get_throw_corlib_exception ().

2004-12-16  Zoltan Varga  <vargaz@freemail.hu>

        * mini-x86.c (mono_arch_emit_epilog): Optimize the corlib exception
        throwing code to reduce its size, unify the AOT and non-aot code and 
        get rid of relocations in the AOT case.

        * mini-x86.h mini.c exceptions-x86.c 
        (mono_arch_get_throw_corlib_exception): New arch specific function to 
        raise corlib exceptions which doesn't require relocations in the 
        caller.

        * aot.c (emit_method): Handle PATCH_INFO_NONE as well.

2004-12-15  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_emit_method_call): Only allocate the got var when it is
        needed.

        * mini-x86.c (mono_arch_patch_code): Add missing PATCH_INFO_METHOD_REL
        in the AOT case.

2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c, cpu-pentium.md, inssel-x86.brg: Fixed bug
        with add function when used from Inc/dec atomic 
        functions. Re-enabled optimization on x86.
        * mini-ops.h: renamed atomic_add functions to
        allow _add to match the Interlocked::Add and
        _add_next to match Interlocked::Inc/Dec.

2004-12-15  Massimiliano Mantione  <massi@ximian.com>

        * mini.c: Fixed a subtle bug in mono_method_to_ir, about the
        linking of BBs to the end BB, and enabled SSAPRE also with
        consprop and copyprop (which was prevented by that bug).

2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c: disabling the Interlocked optimizing code.

        file version check.
        
2004-12-14  Patrik Torstensson  <patrik.torstensson@gmail.com>

        * mini-x86.c, inssel-x86.brg, cpu-pentium.md: removed _imm 
        interlocked optimization due lack of support on x86, rewrote 
        exchange to take into account that base may be in eax.
        
        xsp works again; activated Interlocked optimizing code.
        
2004-12-14  Zoltan Varga  <vargaz@freemail.hu>

        * mini.h (MONO_AOT_FILE_VERSION): Bump AOT file version.

        make it work with all kinds of patchable code.

        * inssel.brg inssel-x86.brg: Add new rules dealing with computing the
        address of the GOT, and referencing entries in the GOT.

        * mini-ppc.c (mono_arch_patch_code): Hopefully made this build
        again. `patch_info->table_size' is no longer valid after Zoltan's
        commit #37636.

2004-12-12  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): Only call mono_debug_init_method()
        if we are the "real" method, ie. not an inlined method inside it.

2004-12-11  Ben Maurer  <bmaurer@ximian.com>

        * mini.c (CEE_LDSFLD): Make sure that the vtable has been init'd
        before we look in the special fields table. This fixes
        ../tests/thread-static-init.cs.

2004-12-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * mini.c: return immediately after setting OP_ARRAY_RANK or CEE_LDLEN
        for Array get_Rank and get_Length. Fixes bug #70465.

2004-12-11  Zoltan Varga  <vargaz@freemail.hu>

        * mini.h mini.c aot.c: Put the bblock table for a SWITCH patch into a

        to return a MonoInst instead of opcode 
        (renamed mini_get_opcode_for_method to better reflect the new functionality)
        
        * mini-[x86|s390|s390x|ppc|sparc].c (mono_arch_get_inst_for_method): 
        Allow ports to return a created MonoInst instead of op-code, will enable
        new optimizations.

        Fixes #69985.

2004-12-08  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_CALLVIRT, use `fsig->signature'
        if we're a CEE_CONSTRAINED call.  Fixes gen-118.cs.

2004-12-08  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_output_basic_block): Implement OP_FCONV_TO_<X>
        correctly.

        * exceptions.cs: Disable some tests which depend on properties of x86 fp
        arithmetic.

2004-12-08  Raja R Harinath  <rharinath@novell.com>

        * mini-s390.c : Implement vararg and TYPEDEBYREF support.

2004-11-30  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_CALLVIRT, added support for
        virtual generic methods.  We call a special helper_compile_generic_method()
        icall to retrieve the method from the vtable, inflate and compile
        it and then do a CEE_CALLI.  Thanks a lot to Paolo for this idea.

        * jit-icalls.c (helper_compile_generic_method): New JIT icall.

2004-11-30  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c: Fix up vararg corner cases. Fixes #70019.

        platforms with PIC aot.

2004-11-28  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_DUP, added handle_stobj().
        Fixes gen-112.cs.

2004-11-28  Martin Baulig  <martin@ximian.com>

        * mini-x86.c (mono_arch_call_opcode): Use the original type, not
        the result of mono_type_get_underlying_type() to check whether
        we're byref.

2004-11-26  Martin Baulig  <martin@ximian.com>

        * mini.c
        (mono_method_to_ir): Use `!method->signature->has_type_parameters'
        in the g_assert().

2004-11-26  Zoltan Varga  <vargaz@freemail.hu>

        * mini-amd64.c (mono_arch_emit_this_vret_args): Handle this and vret
        the same way as the other arguments so they won't get clobbered.

        * mini-amd64.c (mono_arch_output_basic_block): Avoid doing virtual 
        calls through R11 since it is clobbered by the trampoline code.

2004-11-26  Raja R Harinath  <rharinath@novell.com>

        * Makefile.am: Consistently use $(RUNTIME) rather than ./mono to
        pick up in-tree mscorlib.dll.

2004-11-25  Zoltan Varga  <vargaz@freemail.hu>

        * aot.c: Rename MonoAOTModule->cleanup to out_of_date.

        * mini-amd64.c aot.c: Switch to PIC relative AOT code. References to 
        runtime data/code are now stored in a table similar to the GOT in ELF. 
        This allows the code itself to be position independent.

        * aot.c: Fix loading of referenced assemblies after the lazy assembly
        loading changes.

        * aot.c: Attach ELF type (object/function) directives to all global
        symbols.

        * tramp-amd64.c (amd64_magic_trampoline): Patch RIP relative calls too.

        * inssel.brg (SWITCH): Emit an AOT_CONST in the aot case.

        * mini-amd64.h: Turn on PIC AOT code.

        * mini.h (mono_arch_get_aot_patch_offset): New arch specific function
        returning the offset within an OP_AOTCONST instruction where the GOT
        offset needs to be added.

        * mini.h: Bump AOT file format version.

2004-11-25  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): In CEE_CALL, don't allow calling any
        uninflated generic methods.

2004-11-25  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): Don't allow any uninflated generic methods.

2004-11-24  Martin Baulig  <martin@ximian.com>

        original klass (this only applies for generic instances).

2004-11-24  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): Use `STACK_OBJ' instead of
        `ldind_type [CEE_LDIND_REF]' (which would be beyond the end of
        that array).

2004-11-24  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Disable inlining for methods containing
        localloc. Fixes #69678.

2004-11-23  Zoltan Varga  <vargaz@freemail.hu>

        * mini-amd64.c (mono_arch_output_basic_block): Set %al to the number of
        used SSE registers on pinvoke calls. Fixes #69774.

2004-11-23  Geoff Norton  <gnorton@customerdna.com>

2004-11-07  Ben Maurer  <bmaurer@ximian.com>

        * tramp-*.c: we no longer support icalls without wrappers, so
        a bit of code can be removed here

2004-11-07  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions-sparc.c (get_throw_exception): Fix more bugs in previous
        patch.

        * cpu-sparc.md: Add op_rethrow.

        * helpers.c: Change otool arguments from -V -v -t to -v -t on Darwin
        Makes the output much easier to read

2004-11-05  Ben Maurer  <bmaurer@ximian.com>

        * ssa.c: allocate MonoMethodVar.uses from the mempool. First, this
        prevents another huge leak when compiling with ssa. Secondly, the
        performance of doing this rather than freeing the lists is much
        better. GList does a lock every time you allocate a list link,
        so that it can use a memory pool. So, it is better to just use
        a memory pool of our own.
        
        * ssa.c, linear-scan.c: replace g_list_remove_link with
        g_list_delete.  The remove one does not free the GList, so we were
        leaking memory. On -O=all --compile-all with corlib, this cut down
        3 MB of allocations.

        * trace.c (get_spec): Allow tracing of classes without a namespace.

2004-11-02  Sebastien Pouliot  <sebastien@ximian.com>

        * mini.c: Fix pointer overwrite in mini_method_compile.

2004-11-2  Geoff Norton  <gnorton@customerdna.com>

        * inssel-ppc.brg (OP_OUTARG_VT (CEE_LDOBJ (base))):
        The darwin ABI needs some special handling for 1 and 2 byte structs
        Lets use lbz/lhz instead of lwz everywhere.
        * mini-ppc.c (calculate_sizes):  The Darwin ABI needs from special handling
        for 1 and 2 byte structs and struct which are size >= 3 || size % 4 != 0.
        Use stb/sth for the former, and put the latter always on stack instead of in
        argument registers.

2004-10-30  Zoltan Varga  <vargaz@freemail.hu>

2004-10-26  Miguel de Icaza  <miguel@ximian.com>

        * mini.c (mono_jit_free_method): Provide extra information for
        this error.  Currently this leaks, but will be turned into a

        methods as their native size, fixed bug #57543, #57545.
        * mini-ppc.c (mono_arch_output_basic_block): Use mulli for imm16 types
        This saves a temporary register and mullw call down into 1 (minor perf
        increase for cases like sum = sum * 5;  This use to translate into:
            li r11,5
            mullw r28,r28,r11
        It now translates to
            mulli r28,r28,5

        code.

2004-09-06  Martin Baulig  <martin@ximian.com>

        * mini.c (mono_method_to_ir): When initializing locals, handle a

        constrained calls.

2004-07-12  Ben Maurer  <bmaurer@ximian.com>

        * mini-x86.c (OP_CHECK_THIS): cmp DWORD PTR [eax], eax
        is one byte shorter than cmp DWORD PTR [eax], 0.

Mon Jul 12 17:47:00 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * inssel-ppc.brg: arguments on the stack are always
        relative to the stack pointer (spotted by Neale Ferguson).

2004-07-11 Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * exceptions-x86.c: delay appending the method name to the trace until
        after mono_jit_info_table_find is called, as this gets the real
        MonoMethod.

2004-07-09  Ben Maurer  <bmaurer@ximian.com>

        * aot.c: register roots

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : I could just use PLATFORM_WIN32 flag.

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : Reverting the previous fix. This time it broke linux build.

2004-07-09  Atsushi Enomoto  <atsushi@ximian.com>

        * aot.c : quick cygwin build fix. mkdir() with two args does not exist.

2004-07-08  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (handle_stack_args): Remove some more debugging code.
        
        * mini.c (handle_stack_args): Remove debug output left in by mistake.

        * driver.c mini.h aot.c: Allow additional options to be specified with
        --aot and pass them to mono_compile_assembly.

        * aot.c: Add experimental code to AOT compile all loaded assemblies
        on demand and save the code into a cache in the filesystem.

        * aot.c: Add support for more wrapper methods.
        
        * mini.c (handle_stack_args): Handle some corner cases. Fixes 
        58863.

        * cpu-*.md: Remove removed opcodes.

        * mini.h mini.c: Move JIT icall handling to icall.c. Replace usage of
        CEE_MONO_PROC<x> with CEE_MONO_ICALL. Move registration of marshalling
        related icalls to marshal.c.

2004-07-06  Zoltan Varga  <vargaz@freemail.hu>

        * mini-ops.h: Add OP_SAVE_LMF and OP_RESTORE_LMF.

        * Makefile.am (EXTRA_DIST): Add inssel-long[32].brg.

        * inssel.brg: Fix warning. Add rules for SAVE_LMF and RESTORE_LMF.

2004-07-06  Ben Maurer  <bmaurer@ximian.com>
        * liveness.c: If liveness is recomputated we need to reset the information
        for each variable. This way, if the liveness range has been narrowed
        by optimizations that happened after the last computation, we can return
        a smaller range.
        
        For example, if you have
        
        {
                int i = 0;
                
                // Tons of code that does not affect i
                
                i = foo ();
                ...
        }
        
        i = 0 is dead code and will be removed by SSA. However, when
        linear scan gets to the code, i will still appear to be live
        throughout the entire block. This prevents good register allocation.

2004-07-06  Martin Baulig  <martin@ximian.com>

        * debug-mini.c (mono_debug_init_method): Allow
        MONO_WRAPPER_MANAGED_TO_NATIVE wrappers.
        (mono_debug_add_icall_wrapper): New method.

        * mini.c (mono_icall_get_wrapper): Call mono_debug_add_icall_wrapper().

Mon Jun 28 18:05:09 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: reinstated mono_compile_get_interface_var()
        on x86, too, since the change breaks the Gtk# build there as well.

Fri Jun 25 17:36:28 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * driver.c: remove loop from the default optimizations: it seems to
        interact badly with some of the other options (see bug #60613).

2004-06-25  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c mini-x86.h mini-x86.c: Applied patch from Guenter Feldmann 
        (fld@informatik.uni-bremen.de): Add Solaris x86 support.

Tue Jun 22 21:29:11 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: small updates to be able to compile
        vararg-using methods.

2004-06-21  Martin Baulig  <martin@ximian.com>

        * mini/mini-exceptions.c
        (mono_handle_exception): Added `gpointer original_ip' argument.
        After calling mono_unhandled_exception(), call
        mono_debugger_unhandled_exception() and if that returns true,
        restore the context and return.

Mon Jun 21 19:26:40 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c: prefer the use of relative branches so
        they won't need to be patched in aot code (patch from Patrick Beard).

Mon Jun 21 19:03:18 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * aot.c: patch from Patrick Beard to make the output assembly
        more correct for the MacOSX assembler. Small tweak to
        generate sane images on Linux/PPC, too.

Fri Jun 18 18:24:28 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c, mini.h, mini-ppc.c: handle varargs methods with a special
        case until bug #59509 is fixed (shows up in #60332).

Tue Jun 15 16:36:51 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: make sure the needed wrappers are compiled, too, with
        precomp.

Mon Jun 14 18:36:08 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * driver.c: remove NPTL reference in --version output.

        generate valid assembly for the Mach-O assembler.

Sun Jun 13 15:59:38 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * driver.c: don't include abcrem in the all optimization specifier
        since it slows down jit compilation too much for now.

2004-06-12 Ben Maurer  <bmaurer@users.sourceforge.net>

        * mini.c: use BIGMUL only if both operands have the same signage.
        * iltests.il: Test for bug 60056. (errors related to signage in
        BIGMUL).

        r=lupus.

Tue Jun 8 15:36:30 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * Makefile.am: remove the -static hack completely, it links in
        statically glib as well.

Sat Jun 5 16:32:33 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * iltests.il, mini.c: fixed bug#59580 in branch optimization.
        * exceptions.cs: make it compile with new mcs/csc.

2004-06-03 Massimiliano Mantione <massi@ximian.com>
        * cpu-pentium.md basic-float.cs Fixed bug on fpu spills (see bug 54467),
        and added relevant test case.

Mon May 31 19:41:46 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c revert Zoltan's fix to bug#58863 on ppc, since it causes
        regressions in gtk-sharp.

2004-05-29  Zoltan Varga  <vargaz@freemail.hu>

        * exceptions.cs: New regression tests.

        * mini-sparc.h (MONO_ARCH_NEED_DIV_CHECK): Define this.

        * cpu-sparc.md mini-sparc.c: Add overflow detection to div opcodes.

2004-05-28      Patrik Torstensson <totte@hiddenpeaks.com>

        * mini.c (mono_jit_runtime_invoke): Init class in this
        method instead of trusting mono_jit_compile_method to
        do the work (because wrappers can be in object class)

2004-05-27  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_output_basic_block): Fix sub.imm.

        libmono (track build dependencies).

2004-05-26  Zoltan Varga  <vargaz@freemail.hu>

        * cfold.c: Some glib versions do not have G_MININT32.

        * mini-x86.c cpu-pentium.md Makefile.am basic-math.cs: Fixed problem
        with precision of tan, atan, sin and cos, and implemented related
        regressions tests (fixes bug 54467, but one new problem appeared and
        is not fixed yet).

2004-05-26  Zoltan Varga  <vargaz@freemail.hu>

        * cfold.c (FOLD_BINOPZ): Avoid division by zero.

        * exceptions.cs: Add test for constant folding && division by zero.

        * driver.c mini.h mini.c mini-x86.c: Revert most of the previous patch
        since driver.c is in libmono too, so the optimization was useless.

        * driver.c mini.h mini.c mini-x86.c: Moved the mono_lmf_addr TLS 
        variable to driver.c so the compiler can emit more efficient code to
        access them.

2004-05-26  Gonzalo Paniagua Javier <gonzalo@ximian.com>

        * Makefile.am: don't distribute generated inssel.[ch] files.

2004-05-25  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_jit_compile_method_with_opt): Really emit icall wrappers
        into the default appdomain. Fixes #58707.

        * jit-icalls.c: Remove the broken approximation for truncl, doing
        no conversion is better.

        * mini.c (handle_stack_args): Avoid reusing variables for stack slots.
        Fixes #58863.

Tue May 25 14:33:56 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ops.h, mini-ppc.c, cpu-g4.md, inssel-ppc.brg: eliminate the use
        of the mcrxr instruction which is not available on some processors
        even if it's documented to be. Implement add and sub overflow correctly
        (still not complete for long unsigned). Speed up icalls a bit.

2004-05-25 13:01 CET Patrik Torstenson <totte@hiddenpeaks.com>

        * mini.c (mono_jit_compile_method_with_opt): Make sure that
        we run .cctor in the current domain instead of target_domain.
        
        Fixes bug #58558, .cctor not being called in -O=shared.

Tue May 25 12:46:50 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.h, jit-icalls.c: added explicit checks for divide by zero.

2004-05-24 Ben Maurer  <bmaurer@users.sourceforge.net>

        * mini-x86.c (EMIT_COND_BRANCH): If an OP_LABEL has an offset
        which can be done with an imm8, do it that way.
        (mono_arch_output_basic_block): ditto for a jmp
        (mono_arch_emit_prolog): Computate maximum offset of a label.

2004-05-24 18:18 CET Patrik Torstenson <totte@hiddenpeaks.com>

        * mini-x86.c (mono_arch_local_regalloc): the reg allocator
        now tries to allocate prefered physical reg's for virtual
        regs. This reduces the number of emited spills/loads with
        20-30% on our core assemblies.

Mon May 24 18:21:51 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * jit-icalls.c: truncl() is not needed and trunc() is
        the correct thing to do anyway (bug #58287).

2004-05-24  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_flush_icache): Call sync_instruction_memory

2004-05-23  Zoltan Varga  <vargaz@freemail.hu>

        * ssa.c (mono_ssa_cprop): Allocate carray dynamically instead of on
        the stack.

2004-05-22  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c (mono_arch_output_basic_block): ADD_IMM and SUB_IMM
        should set carry.

        * basic-long.cs: Add tests for add/subtract of immediates with carry.

        * mini.c exceptions-x86.c: Remove MONO_USE_EXC_TABLES stuff.
        
        * mini.c (inline_method): Allways inline some wrappers even if the cost
        is too large. Fixes #58785.

        * mini.c: Add support for MARSHAL_CONV_FTN_DEL.
        
2004-05-21  Zoltan Varga  <vargaz@freemail.hu>

        * mini-sparc.c exceptions-sparc.c: Applied patch from Mark Crichton
        (crichton@gimp.org). Beginning of support for sparc/linux.

2004-05-20  Lluis Sanchez Gual  <lluis@ximian.com>

        * mini.c: Delegate most of the abort signal work to 
          mono_thread_request_interruption, which also handles Stop and Suspend
          states.

2004-05-20  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c mini.h: Allow inlining of icall wrappers if the backend 
        supports the save/restore lmf opcodes.

2004-05-19  Zoltan Varga  <vargaz@freemail.hu>

        * mini-x86.c (mono_arch_setup_jit_tls_data): Handle code generated
        by gcc-3.4 as well.

        * mini-x86.h mini-x86.c tramp-x86.c: Optimize lmf restoring code.

2004-05-18  Zoltan Varga  <vargaz@freemail.hu>

        register too early on the chain.

2004-05-18  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (create_helper_signature): Use a helper function to reduce
        the code which needs to be written. Also set the calling convention of
        icalls on windows. Fixes #57840.

Tue May 18 11:05:18 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.h, exceptions-x86.c, exceptions-sparc.c, exceptions-s390.c,

        * Makefile.am (common_sources): added abcremoval.h so it get
        disted and daily mono packages on go-mono.com will build again

2004-05-17  Massimiliano Mantione  <massi@ximian.com>

        * abcremoval.c: Fixed coding style, added copyright header.

        * abcremoval.h: Fixed style and moved prototype to mini.h, added copyright header.

        * mini.h: Added prototype for abc removal main function.

        * build_relations_propagation_table.pl: Added copyright header.

Thu Apr 29 16:47:15 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini-ppc.c, cpu-g4.md: fixed unisgned -> double conversion.

        Move some parts of the x86 exception handling code to an 
        arch-independent file so it can be shared with other ports.

Tue Apr 27 12:15:59 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * trace.c, cpu-g4.md, inssel-ppc.brg, mini-ppc.c: some fixes for FP code.

2004-04-26  David Waite  <mass@akuma.org>

        * driver.c: remove comma from end of enumeration declaration

2004-04-26  Jackson Harper  <jackson@ximian.com>

        * driver.c: parse config file before loading first assembly. This
        allows the user gac to be enabled/disabled. 
        
2004-04-23  Miguel de Icaza  <miguel@ximian.com>

        * mini-ppc.c (ppc_patch): Replaced the branch code patching with a
        simpler mechanism: we do not care what is encoded initially
        (branch absolute or relative), we care about the code and its
        target.  I kept the old code for reference for now.

        The new code tries first to determine if the jump is anywhere in
        the -/+32 absolute meg range, if it succeeds, it encodes using the
        absolute branch;  If not, it tried to find something in the
        relative range, if not, it uses the handle_thunk code. 

Fri Apr 23 14:20:40 EDT 2004 Paolo Molaro <lupus@ximian.com>

        Raise exception on integer divide by zero by hand since the hw
        doesn't support it. Handle NaNs in FP compares.

Thu Apr 22 16:10:31 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions-ppc.c, mini-ppc.h, mini.c: simplified some
        code reducing duplication between the platforms and enabled
        signal exception handling (on linux for now).

Wed Apr 21 12:27:48 EDT 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions.cs (test_0_rethow_stacktrace): Make this work with
        inlining.

2004-04-18 Ben Maurer  <bmaurer@users.sourceforge.net>

        * iltests.il, basic.cs: more tests for regalloc.

        * exceptions-*.c (mono_arch_handle_exception): Do not overwrite the
        original stack trace if an exception is rethrown. Fixes #56782. Oh,
        the beauty of fixing the same thing in 5 different files...

2004-04-15  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c (mono_method_to_ir): Do not compute coverage for inlined
        methods.

2004-04-14  Zoltan Varga  <vargaz@freemail.hu>

        * mini.c: Add support for STRWLPARRAY marshalling convention.

Wed Apr 14 18:15:55 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions-ppc.c: missing fixes in mono_jit_walk_stack (need
        to init the context to setup the regs pointer).

Wed Apr 14 17:59:09 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * exceptions-ppc.c: more exceptions work.

Wed Apr 14 17:46:22 CEST 2004 Paolo Molaro <lupus@ximian.com>

        * mini.c: avoid reusing the same MonoInst on multiple trees: this is
        not allowed.

2004-04-13  Miguel de Icaza  <miguel@ximian.com>

        * inssel-x86.brg (reg): Add new rules for add, sub and mul that

        add x86_add_membase, x86_sub_membase, x86_mul_membase

2004-04-13  Miguel de Icaza  <miguel@ximian.com>

        * mini-ppc.c: Remove unused definitions FLOAT_REGS and
        GENERAL_REGS they were also hardcoded for all PPC ports.

        (add_general): Use PPC_NUM_REG_ARGS instead of GENERAL_REGS.

        Remove hard-coded limit for floating point registers, use
        PPC_LAST_FPARG_REG instead in MONO_TYPE_R4 and MONO_TYPE_R8.

        Notice that in MacOS X calling conventions you can fit a lot more
        floating point values in registers, so I should update the PInvoke
        test to excercise the passing of floating point values on the
        stack (currently broken).
        
2004-04-06  Miguel de Icaza  <miguel@ximian.com>

        * tramp-ppc.c (create_trampoline_code): Added
        JUMP_TRAMPOLINE_SIZE. 
        (ppc_magic_trampoline): Follow the pattern from
        x86_magic_trampoline: if code is set to zero, return. 
        (create_trampoline_code): Always pass MonoMethod to the jump
        trampoline, before it was passing a null.
        (mono_arch_create_jump_trampoline): Implement the jump stub, could
        share the code with mono_arch_create_jit_trampoline.

        (mono_method_to_ir): Added `constrained_call' variable.
        (mono_method_to_ir:CEE_CONSTRAINED_): Set it.

        mono_method_get_constrained() to get the method.

2004-04-01  Martin Baulig  <martin@ximian.com>

        * mini.c (TYPE_PARAM_TO_TYPE, TYPE_PARAM_TO_CLASS): Removed.
        (MTYPE_PARAM_TO_TYPE, MTYPE_PARAM_TO_CLASS): Removed.

        * aot.c: set aot_verbose to 0, fixed format string that caused sigsegv,
        use @function (as doesn't accept #function here) and check the return

        * inssel.brg mini-ops.h mini.c: Use OP_REFANYTYPE instead of 
        CEE_REFANYTYPE, since CEE_REFANYTYPE needs a prefix to be unique.

        * inssel.brg: Fix register allocation in OP_ARGLIST.

        * inssel.brg: Fix warnings.

2004-03-25  Martin Baulig  <martin@ximian.com>

        type being casted is marshalbyref it could be a proxy, so instead of
        emitting the type check code, emit a call to a runtime method that will

2003-04-28  Zoltan Varga  <vargaz@freemail.hu>

        * Makefile.am: Link with -export-dynamic so shared libs loaded by
