794 through inclusion of tc-hppa.h. Delete all forward declarations
795 for functions only used within tc-hppa.c, likewise for structures,
796 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
797 conditional code in a few small places.
799 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
800 structures, global variables, forward declarations together.

803 into a few places. Make all functions and variables which
804 are only used within tc-hppa.c static. PARAMize all functions.
805 Add comments to functions. Delete unused functions, variables,
806 #defines, etc. Delete unused members within structures. Delete
807 ldil;ble hacks -- it is believed they were installed to work
808 around old gas bugs. Avoid using mixed case for local
809 functions, variables, and structures. Fix formatting problems
810 not found by GNU-indent. Add FIXME notices for things which
811 should be worked on the near future. Delete lots of old

885 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
887 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
888 ELF, since the ELF object format does not have these type of
889 relocations. Change the abort into as as_bad and return
890 BFD_RELOC_NONE to silence compiler warnings.

892 space between the $ and the constant for compatibility with older
893 gases and other assemblers.
894 (i386_operand): Skip spaces between $ and expression.

1880 prev_prev_insn_unreordered): New static variables.
1881 (append_insn): Don't swap branch instruction if
1882 prev_prev_insn_unreordered (see comment).
1883 (mips_no_prev_insn): Clear the unreordered variables.
1884 (s_mipsset): When turning on reordering, set the unreordered
1887 Fri Jul 23 13:09:44 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
1889 * config/obj-elf.c (obj_elf_section): Sections ".init" and ".fini"
1890 are also magic, and have special default flag settings.
1891 (obj_elf_frob_symbol): Since the return value from this function
1892 isn't used, don't bother calling obj_elf_write_symbol_p, since it
1893 doesn't accomplish anything else.
1895 * config/tc-sparc.c (md_section_align): Round up section size only
1898 * symbols.c: Don't define DEBUG by default.

1904 * expr.c (expr): Don't let absolute_section override
1905 undefined_section for the return value.
1907 * read.c (read_a_source_file): In NO_PSEUDO_DOT case, if we find a
1908 pseudo-op with a poc_handler field of NULL, ignore it and treat it
1909 as an instruction instead.
1910 * config/tc-m88k.c (md_pseudo_table): Add "set" with a NULL
1913 * config/tc-h8500.c (md_begin): Use a local variable when

1925 * configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
1926 case to set obj_format=elf. Must go before i386-*-sysv* case that
1927 sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
1928 *-*-solaris case, and move to before *-sysv* case that wants to
1929 set obj_format to coff.

1955 * Extensive changes to permit symbols to contain any expression
1956 type and to delay the computation of the expression until the
1957 value is actually needed. This permits setting symbols to values
1958 calculated based on object code size. Expressions were changed to
1959 no longer be in a section, to stop the overloading of segment and
1960 expression type that previously occurred.
1962 * as.c (big_section, pass1_section, diff_section, absent_section):
1964 (expr_section): Added (used for dummy symbols which hold

2048 (previous_section, previous_subsection): New vars.
2049 (obj_elf_section): Save current place in case DWARF code wants us
2050 to pop back to it. Handle unquoted section name as well as quoted
2051 section name. Don't crash on invalid strings.
2052 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2164 sy_resolved and sy_resolving single bit fields.
2165 * symbols.c (symbol_new): Don't initialize sy_forward field.

3327 dropping a space immediately following an identifier.
3328 * expr.c, write.c: Rewrote assert expressions to not use multiple
3329 lines; I don't think that can be done portably.
3330 * config/tc-mips.c (macro): Use $AT if target register is zero in
3331 load instruction, which it can be for a floating point load.

3405 prototypes for all static functions. Moved existing minimal
3406 debugging format support info #ifndef OBJ_ECOFF blocks.

3455 * make-gas.com: Find obstack.obj if it's not in the current
3457 * read.c (s_ignore): Don't declare is_end_of_line. It's
3458 redundant, and triggers a VMS gcc compiler bug.
3460 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3461 current segment as an argument. (Ignored in all cases but VMS.)
3462 All callers and definitions changed.

3791 * expr.c: Add "const" modifier to hex_value.
3792 * symbols.c: Finish conversion to S_* macros in the VMS only
3793 parts of the program. Add "const" modifier to
3794 md_[long,short]_jump_size. Remove declaration of const_flag
3795 (which will be declared in obj-vms.h).
3796 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3797 Fix arguments to VMS_write_object_file.
3798 * config-gas.com: New file. Script for VMS systems to set up the
3799 configuration to build gas for VMS, and create config.status.
3800 * make-gas.com: Redone to work with new scheme.
3801 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3803 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3804 will swap bytes if needed on a big endian system. Use throughout
3806 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3807 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3808 types of malformed stabs. Change parsing algorithm so that we are
3809 more certain of having all of the information that we need on hand.
3810 * obj-vms.c (final_forward_reference): New function, used to help
3811 resolve the data types of as many struct elements as possible
3812 when some part of the struct is not fully defined by the compiler.

3815 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3816 as symbols as well in the object file. Look for external functions

3818 g++ compiler is incapable of doing this.
3819 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3821 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3822 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3823 have the name of the source file yet.

3829 SEG_DATA or SEG_E1 if needed.
3830 (s_lcomm): Likewise with bss_section.
3831 (s_fill): Use memset, not bzero.
3833 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

3858 mapping to segT enum values.
3859 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3860 if these are used or defined, if BFD_ASSEMBLER.
3861 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3862 subseg_new split into two functions.
3863 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3865 * as.h (volatile): Don't define if already defined.
3866 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3868 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3869 declare with format attribute for -Wformat checking.
3871 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3873 * app.c, config/tc-*.c: Don't include read.h, since it is already
3876 * These are based on patches from Minh Tran-le
3877 <mtranle@paris.intellicorp.com>.
3878 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3879 obj_format coffbfd and gas_target i386coff for target.
3880 (i[34]86-*-isc*): New host (uses sysv).
3881 * config/i386aix.mt: Removed (no longer used).
3882 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3884 (LDFLAGS): Added, defined as -shlib.
3885 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3886 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3887 (DOT_LABEL_PREFIX): Define.

3889 name rather than L0\001.
3890 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3892 * symbols.c, symbols.h (local_bss_counter): Removed.

3901 (size_section): Restored sanity check.
3902 (do_relocs_for): Base section address on s_paddr rather than
3903 computing it. Adjust a29k R_IHIHALF special case to account for
3904 section paddr (used to require paddr to be zero). If there are no
3905 reclos, set s_relptr to 0. Set relocation size in object_headers.
3906 (fill_section): Always set s_vaddr here, removing
3907 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3908 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3909 Set STYP_INFO for .comment.

3913 H_{SET,GET}_* macros.
3914 (do_linenos_for): Set lineno size in object_headers.
3915 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3916 set s_vaddr here. If string_byte_count remains 4, set it back to
3917 0, and only write strings out if there are some. Call
3918 fill_section before do_relocs_for and do_linenos_for.
3919 (obj_coff_section): Handle optional quoted second argument giving
3920 section characteristics.
3921 (obj_coff_bss): Added to handle .bss.

3942 (do_scrub_next_char): For \", return " not '.
3943 (symbol_chars): Now const.
3945 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3946 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3948 * config/obj-coff.h: Don't use #elif.
3950 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3951 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

3980 never set segment address for SEG_E2 (.bss) and don't write out
3981 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3982 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3983 definitions, and don't merge tags with non-tags. Check for .bf
3984 rather than just checking whether the second character is b and
3985 the third character is f.
3986 (obj_coff_val): gcc can generate values which we don't handle
3987 correctly; discard information for now, since it only affects the
3988 debugging information.

3990 (yank_symbols): Don't merge labels.
3991 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4262 * read.c (cons): If NO_RELOC is defined, use it.
4264 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4266 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4268 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4269 local labels to start with a .) and set REGISTER_PREFIX to %.
4270 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4288 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4289 sections starting from zero, rather than making them consecutive.
4290 This makes subsequent reloc calculations easier, esp if the object
4291 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4292 allocate lcomm in .data rather than in .bss. It seems that some
4293 tools can't cope with a non-zero sized bss before linkage.

4297 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4298 throughout. That enum no longer means what we thought it meant.

4321 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4322 .word is < -32768 or > 32767. The -J flag causes the error to be
4323 ignored. This is to catch over-sized switches generated by gcc on
4324 systems which don't support the broken .word hack.
4325 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4326 write.c (fixup_segment): check for signed .word overflow if
4327 WARN_SIGNED_OVERFLOW_WORD.
4329 * write.c (fixup_segment): fixed missing parens in expression
4330 checking for byte or word overflow.

4356 From Steve Chamberlain:
4357 Makefile.in: Handle m68*-*-coff*.

4371 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4373 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4376 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)

4405 * config/tc-m68k.c (init_table): Now const. Always include 68851
4406 data, so that "bc" is available to 68040 cache instructions.
4407 Added "tt0", "tt1", and 68ec030 variants.
4408 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4409 (enum _register): Added TT0, TT1.
4410 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4411 line number correctly in "internal error" messages. Don't print
4412 architecture-mismatch message for operand errors.

4437 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4438 has already been formatted (but may still contain %-characters).
4441 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4443 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4444 written with indirection on the last two operands, which can be
4445 either data or address registers. Added a new operand type 'r'
4446 which accepts either register type. Added '(' to notend stuff in
4447 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4758 * Makefile.in: added tooldir and program_prefix.
4760 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
4762 * write.{c,h} (fix_new): Make these declarations consistent.
4764 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4766 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4769 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4771 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4773 * expr.c (operand): if can't work out what sort of operand it is,
4774 then look through FLT_CHARS for a hint.
4776 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4778 * Makefile.in, configure.in: removed traces of namesubdir,
4779 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4780 copyrights to '92, changed some from Cygnus to FSF.
4782 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4783 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4784 copyrights to '92, changed some from Cygnus to FSF.
4786 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4788 * expr.c: If an expression is single comma, then return with
4789 SEG_ABSENT rather than an error - since the sparc front end does
4790 really strange things with things like fbge,a
4792 * as.h: include bfd.h if using many sections
4793 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4794 local labels didn't work.
4795 * listing.c (list_symbol_table): don't core dump when there's no
4797 * write.c, write.h: call fix_new with the right number of args on
4799 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4802 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4804 * app.c: MRI compatibility - allow single quote to start a string.
4805 * as.c: fix typo recently introduced.
4806 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4807 * expr.c: Much rewriting, to accomodate MRI syntax for
4808 expressions. Also easier to read now.
4809 * listing.c: Put back defuns
4810 * read.c: modified to accept MRI syntax, put back listing pseudo
4811 ops so that an assembler built with NO_LISTING ignores list ops
4813 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4814 machine is a SPARC or a 29K.
4815 * config/obj-aout.c: added s_sect pseudo op
4816 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4817 fill in the timestamp.
4818 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4819 anymore, define all the relocs which the tc-<x> bit will use so we
4820 can translate from them to the coff types.
4821 * config/tc-a29k.c: reloc_type isn't ane enum any more
4822 * config/tc-m68k.c: Added NO_RELOC definition.
4824 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4826 * Makefile.in: put header files before C source for TAGS; remove
4827 references to non-existent syscalls.h.
4829 * read.c, write.c subsegs.c: back out the .bss changes.
4831 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4833 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4837 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4839 * symbols.c (local_label_name): symbols now start with ^A.
4841 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4842 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4843 generate these sections. .align: will use NOP_OPCODE or 0
4844 for padding. This is just for being nice to the
4847 * expr.c (operand): changed to generate local label "\001L0"
4848 starting with a ^A so that it is recognized as a local label.
4850 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4852 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4853 i/o opcodes - inb, inw, outb and outw. string manipulation with
4854 att syntax - scmp, slod, smov, ssca, ssto.
4856 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4857 to just after .file .
4859 In obj_crawl_symbol_chain() where it tries to put the external
4860 symbols apart, with the condition:
4861 (!S_IS_DEFINED(symbolP) &&
4862 !S_IS_DEBUG(symbolP) &&
4863 !SF_GET_STATICS(symbolP))
4864 it was moving too many symbols out. So I switch it back to the
4866 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4868 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4869 so that we don't use the F_RELFLG which make the linker complain
4870 that somebody has stripped the relocation info.
4872 Also, the AIX ld program require that the relocation table
4873 is sorted by r_vaddr like the standard ATT assembler does.
4875 [he also changed the sizeof(struct ...)'s into the coff
4876 style FOOSZ macros. I'm not sure this is right, but I can't
4877 remember why. xoxorich.]
4879 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4881 * Makefile.in, configure.in, doc: use the doc. Build it, install
4884 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4886 * read.c: white space and comments only.
4888 * configure.in: use the new atof-ns32.c for ns32k.
4890 * write.c: comment change only.
4892 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4893 aren't yet integrated.
4895 * tc-i860.[hc]: blew off the dust. Something must still be done
4896 about conflicting relocation types.
4898 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4901 * tc-i960.c, tc-sparc.c: white space and comments only.
4903 * tc-a29k.h: delete duplicate macro definition.
4905 * new file atof-ns32k.c copied from hack's last unreleased gas.
4907 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4909 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4912 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4913 ChangeLog's prior to this are sketchy at best. I have logs.
4914 They just aren't ChangeLogs.
