        (libgcc2.a): Add missing semicolon in commented code that could cause

        them out (this reduces memory usage in some pathalogical cases by a
        significant amount without resorting to sparse matrices).
        (propagate_block): Make code a bit more efficient (for example,
        no need to test `loop_depth' for each insn, just notes).

        for TARGET_MILLICODE_LONG_CALLS.  Emit an inline long-call if
        needed.  If emitting an inline long-call, perform argument relocations
        before the call if they are needed, unfill the delay slot of the
        call if necessary.
        * pa.md (define_delay for millicode): Disable the delay slot if
        TARGET_MILLICODE_LONG_CALLS.
        (millicode insns and indirect calls): Properly compute length for 
        both TARGET_PORTABLE_RUNTIME and TARGET_MILLICODE_LONG_CALLS.
        (call_internal_symref): Properly compute the length when more
        than 240000 bytes of code have already been output.  Take 
        TARGET_MILLICODE_LONG_CALLS into account in the length
        computation.

        * pa.h (DBX_OUTPUT_MAIN_SOURCE_FILE_END): Define.
        (ASM_FILE_END): Delete unneeded definition.

        * Fast indirect call support.
        * pa.h (TARGET_FAST_INDIRECT_CALLS): New target switch.

        * PA PIC support.
        * pa.c (secondary_reload_class): Refine.  Readonly data needs a
        secondary reload only during PIC generation.  Loading a floating
        point register with a constant requires a register from R1_REGS
        during -fPIC code generation.
        (read_only_operand): Constant pool entries are no longer read only
        during PIC code generation.
        (hppa_legitimize_address): If flag_pic is nonzero, then
        immediately call legitimize_pic_address.
        (emit_move_sequence): Call legitimize_pic_address to handle
        constant data.  Handle secondary reloads for PIC.  Use
        pic_label_operand rather than open coding the test.  Handle
        loading a LABEL_REF when generating PIC.
        (legitimzie_pic_address): Handle constant data addressing for PIC
        here.   Fix loading of symbolic addresses for -fPIC generation.
        (pic_label_operand): Renamed from pic_operand.  Handle any read
        only operand (such as constant data).  Reject function addresses,
        Accept SYMBOL_REF with the read-only bit set.  Generalize to
        handle (const (plus (reg) (int))).
        (finalize_pic): Delete unused function.
        (check_pic): Delete function.
        (pic_pc_rtx): Delete variable definition.

        PIC code.
        (finalize_pic): Don't emit code for initialization of

        pic_offset_table_rtx at function end.
        * pa.h (SELECT_RTX_SECTION): Define.  During PIC generation
        everything (in the constant pool) goes into the data space.
        (PRINT_OPERAND_ADDRESS): Handle CONST_INTs during PIC
        generation.  Handle LO_SUM address during -fPIC generation.
        (LEGITIMATE_CONSTANT_P): Reject function labels when generating
        PIC code.
        (GO_IF_LEGITIMATE_ADDRESS): Only accept pic_reg + SYMBOL_REF for
        -fpic.
        (EXTRA_SECTION_FUNCTIONS): For -fpic, use the TEXT section for
        constants to avoid GAS lossage.
        (OVERRIDE_OPTIONS): Delete.
        (PIC_OFFSET_TABLE_REG_CALL_CLOBBERED): Define.
        (FINALIZE_PIC): Delete definition.
        (INIT_EXPANDERS): Define.  Clear hppa_save_pic_table_rtx here.
        * pa.md: Use !flag_pic rather than calling check_pic.
        (HImode high and lo_sum): Only accept const_int_operands.
        (pic_load_label): Force output to be in %r1. 
        (pic_highpart): New pattern.  Output must go into %r1.  More
        linker trickery.
        (symbolic high and lo_sum): Disallow during PIC generation if
        source is a symbolic operand.  Handle CONST_INT LO_SUM during PIC
        generation.  Simplify.
        (define_split for symbolic_operand load): Do not accept a symbolic
        operand that is a pic_label_operand.
        (pic_load_label): Name this pattern.  Mask least significant bits
        and optimize when a simple label is within reach of an ldo.
        (call, call_value): Emit new-style USE information for
        pic_offset_table_rtx.  Emit code for initialization of
        hppa_save_pic_table_rtx and wrap it into push_topmost_sequence()
        and pop_topmost_sequence() calls. 

        * Various PA configuration cleanups.  
        * configure (hppa*-*-h[pi]ux): Use xm-pahpux.h and x-pa-hpux instead
        of the redundant hiux files.  Likewise for t-pa instead of t-pa-hpux.
        * config/pa/xm-pahiux.h: Delete.  It's identical to xm-pahpux.h.
        * config/pa/x-pa-hiux: Delete.  It's idential to x-pa-hpux.
        * config/pa/x-pa (TAROUTOPTS): Delete.  It was an HPUX host
        conditional, and x-pa is a BSD host target fragment.
        (INSTALL_HEADERS): Define.

        moved across this point.
        (untyped_return): Delete.
        (update_return): Delete.

        flag_cse_follow_jumps and not leaf_function_p to determine whether
        to allocate EDX, and ECX before EAX, use whether or not a DImode
        variable was used in the compilation.  DImode variables seem to
        cause spill failures if EAX is allocated first, while smaller code
        is generated if EAX is allocated first, assuming no spill failure.

        * i386/i386.md (SF, DF, XF, and DI moves and pushes): Eliminate
        special patterns for TARGET_386 that allow direct pushes from
        memory, and instead allow direct pushes from memory as the last
        alternative in case no scratch registers could be allocated.
        (movxf_mem): Remove inadvertent !TARGET_386 condition.
        (addsi3): Allow generation of lea on 486, since the single
        instruction lea is at least as fast as the mov and add it
        replaces.
        (zero extend patterns): Replace !TARGET_486 with TARGET_386.
        (bit extracts): Ditto.

        * expmed.c (store_split_bit_field): Use number of bits in arg not

        * gcc.c: Include <sys/errno.h> in case `errno' is really a macro
        as permitted by ANSI C.  

        * getpwd.c (GUESSPATHLEN): If there is no definition of
        MAXPATHLEN, then set GUESSPATHLEN to be 100.  (It's used
        as a starting point, not a limit, so this is harmless.)

Tue Sep 13 15:02:19 1994  Michael Meissner  <meissner@pasta.osf.org>

        * i386/i386.md (movxf_mem): Fix typo with memory/memory moves
        of XFmode variables, where the store actually did a load, ie, the
        source and destination operands were fixed.
        (fixuns_trunc patterns): Revert to the old code.
        (movdf_push486, movxf_push486, movdi_push486): If an address is

        * i386/i386.h (MASK_*): Add masks for all of the switches.

        -mdebug-addr switch to debug GO_IF_LEGITIMATE_ADDRESS,
        -mno-wide-multiply to turn off widening multiplies, and -mno-move
        to allow integer move insns to generate direct memory to memory
        copies, which reload will fix up.  Add TARGET_386 which is not of
        TARGET_486.
        (REG_ALLOC_ORDER): Go to the order used in 2.5.8, eax, edx, ecx, ...
        Add a comment describing the tradeoffs.
        (REG_OK*): Add strict and non-strict versions of the macros that

        function.
        (LEGITIMIZE_ADDRESS): Move processing to legitimize_address

        here from i386.h.  Combine OSF/rose support from osfrose.h through
        the use of conditional macros.  Only recognize addresses in
        canonical formats, code adapted from the i960 port.  Add tracing
        if -mdebug-addr.
        (legitimize_address): Move LEGITIMIZE_ADDRESS here from i386.h,
        and add adaptations from the i960 port.
        (convert_387_op): Remove unused function.

        * i386/i386.md (various): Remove cast to char * of output
        functions, since i386.h now declares them all properly.  Change

        (movsi, movstricthi, movhi, movstrictqi, movqi, movdi): Add
        define_expand wrappers to prevent memory<->memory moves from being
        generated unless -mno-move is used.  On 486's do not allow push of
        memory insns to be generated unless -mno-move.
        (movdi): For movdi patterns, add 2 (clobber (match_scratch...))
        declarations to allow memory<->memory moves with non-contigous
        registers, so that reload don't abort if it can't make a DI
        register.
        (umulsidi3, mulsidi3): Don't allow pattern if -mno-wide-multiply.
        (smultsi3_highpart, umultsi3_highpart): Add patterns to make
        division by constants generate better code.

        * i386/osfrose.h (MASK_*): Use octal to define bitmasks, not hex,
