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

727 conditional code -- try to group conditional code together
728 into a few places. Make all functions and variables which
729 are only used within tc-hppa.c static. PARAMize all functions.
730 Add comments to functions. Delete unused functions, variables,
731 #defines, etc. Delete unused members within structures. Delete
732 ldil;ble hacks -- it is believed they were installed to work
733 around old gas bugs. Avoid using mixed case for local
734 functions, variables, and structures. Fix formatting problems
735 not found by GNU-indent. Add FIXME notices for things which
736 should be worked on the near future. Delete lots of old
737 useless (1.36 PA-SOM) code.

766 a multiple of the section alignment rather than always a
769 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation

810 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
812 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
813 ELF, since the ELF object format does not have these type of
814 relocations. Change the abort into as as_bad and return
815 BFD_RELOC_NONE to silence compiler warnings.
816 (md_assemble): Keep track of the instruction size. Allow white
817 space between the $ and the constant for compatibility with older
818 gases and other assemblers.
819 (i386_operand): Skip spaces between $ and expression.

1880 * Extensive changes to permit symbols to contain any expression
1881 type and to delay the computation of the expression until the
1882 value is actually needed. This permits setting symbols to values
1883 calculated based on object code size. Expressions were changed to
1884 no longer be in a section, to stop the overloading of segment and
1885 expression type that previously occurred.

2089 sy_resolved and sy_resolving single bit fields.
2090 * symbols.c (symbol_new): Don't initialize sy_forward field.

3218 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

3225 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3227 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3252 dropping a space immediately following an identifier.

3255 * config/tc-mips.c (macro): Use $AT if target register is zero in
3256 load instruction, which it can be for a floating point load.

3279 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3281 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition

3330 prototypes for all static functions. Moved existing minimal
3331 debugging format support info #ifndef OBJ_ECOFF blocks.

3380 * make-gas.com: Find obstack.obj if it's not in the current
3382 * read.c (s_ignore): Don't declare is_end_of_line. It's
3383 redundant, and triggers a VMS gcc compiler bug.
3385 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3386 current segment as an argument. (Ignored in all cases but VMS.)
3387 All callers and definitions changed.

3704 (operand): Treat zero byte as end-of-operand.
3706 * configure.in (per-target): Look for with_bfd_assembler option.
3707 For now, only accept "no", until the merge is done.
3709 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3710 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3711 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3712 * read.c: Finish conversion to S_* macros in the VMS only
3713 parts of the program. Add "const" modifier to hex_value.
3714 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3716 * expr.c: Add "const" modifier to hex_value.
3717 * symbols.c: Finish conversion to S_* macros in the VMS only
3718 parts of the program. Add "const" modifier to
3719 md_[long,short]_jump_size. Remove declaration of const_flag
3720 (which will be declared in obj-vms.h).
3721 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3722 Fix arguments to VMS_write_object_file.
3723 * config-gas.com: New file. Script for VMS systems to set up the

3740 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3741 as symbols as well in the object file. Look for external functions

3782 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3783 mapping to segT enum values.
3784 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3785 if these are used or defined, if BFD_ASSEMBLER.
3786 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3787 subseg_new split into two functions.
3788 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3790 * as.h (volatile): Don't define if already defined.
3791 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3793 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3794 declare with format attribute for -Wformat checking.
3796 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3798 * app.c, config/tc-*.c: Don't include read.h, since it is already
3801 * These are based on patches from Minh Tran-le
3802 <mtranle@paris.intellicorp.com>.
3803 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3804 obj_format coffbfd and gas_target i386coff for target.
3805 (i[34]86-*-isc*): New host (uses sysv).
3806 * config/i386aix.mt: Removed (no longer used).
3807 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3809 (LDFLAGS): Added, defined as -shlib.
3810 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3811 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3812 (DOT_LABEL_PREFIX): Define.
3813 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3814 name rather than L0\001.
3815 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3817 * symbols.c, symbols.h (local_bss_counter): Removed.
3818 * write.c (write_object_file): bss no longer uses
3819 local_bss_counter. Pass correct data and bss size to
3820 VMS_write_object_file.
3821 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
3822 argument, rather than using local_bss_counter.

3824 * config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
3825 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
3826 (size_section): Restored sanity check.
3827 (do_relocs_for): Base section address on s_paddr rather than
3828 computing it. Adjust a29k R_IHIHALF special case to account for
3829 section paddr (used to require paddr to be zero). If there are no
3830 reclos, set s_relptr to 0. Set relocation size in object_headers.
3831 (fill_section): Always set s_vaddr here, removing
3832 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3833 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3834 Set STYP_INFO for .comment.
3835 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3836 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3838 H_{SET,GET}_* macros.
3839 (do_linenos_for): Set lineno size in object_headers.
3840 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3841 set s_vaddr here. If string_byte_count remains 4, set it back to
3842 0, and only write strings out if there are some. Call
3843 fill_section before do_relocs_for and do_linenos_for.
3844 (obj_coff_section): Handle optional quoted second argument giving
3845 section characteristics.
3846 (obj_coff_bss): Added to handle .bss.
3847 (obj_coff_ident): Added to handle .ident (puts string in .comment
3849 (obj_coff_lcomm): Put common symbols in .bss, not .data.
3850 (fixup_mdeps): Change to segment. Call frag_wane after
3852 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3853 adjustment (already happened only for common symbols, but this is
3855 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3866 * app.c (app_push): Use memcpy, not bcopy.
3867 (do_scrub_next_char): For \", return " not '.
3868 (symbol_chars): Now const.
3870 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3871 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
3873 * config/obj-coff.h: Don't use #elif.
3875 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
3876 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
3878 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

3902 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
3903 using ZERO_BASED_SEGMENTS.
3904 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
3905 never set segment address for SEG_E2 (.bss) and don't write out
3906 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
3907 (obj_coff_endef): Don't merge labels or symbols awaiting forward
3908 definitions, and don't merge tags with non-tags. Check for .bf
3909 rather than just checking whether the second character is b and
3910 the third character is f.
3911 (obj_coff_val): gcc can generate values which we don't handle
3912 correctly; discard information for now, since it only affects the
3913 debugging information.
3914 (tag_find_or_name): Don't insert tags in the symbol table.
3915 (yank_symbols): Don't merge labels.
3916 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

3922 relative addends by the segment vaddr.
3923 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
3924 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.

4061 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4062 could be doing emulation.
4064 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4067 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
4070 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

4096 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4098 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4099 constant will not fit in an immediate field.
4100 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4102 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)

4135 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4137 * Support for i386-sysv.
4138 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

4142 (fill_section): Don't set STYP_NOLOAD for .bss section.
4143 (fixup_segment): 386 uses strange common symbol format.

4157 fix i960+non-bfd coff bit rot.
4158 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4159 support for C source listings. (obj_coff_endef): look in the right

4162 * tc-m68k.c (get_num): make it work for all segments, not just the
4165 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4167 * configure.in: recognize i386-*-bsd emulation.

4176 * tc-z8k.c: lots of bug fixes
4178 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4180 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4181 #elif, since it is not supported by old compilers.
4182 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4183 couple of expressions in tc-m68k.c.
4185 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4187 * read.c (cons): If NO_RELOC is defined, use it.
4189 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4191 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4193 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4194 local labels to start with a .) and set REGISTER_PREFIX to %.
4195 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4197 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
4199 * messages.c: Comment changes.
4201 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

4204 * messages.c: If __STDC__ is not defined, define NO_STDARG.
4206 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
4208 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4211 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4213 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4214 sections starting from zero, rather than making them consecutive.
4215 This makes subsequent reloc calculations easier, esp if the object
4216 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4217 allocate lcomm in .data rather than in .bss. It seems that some
4218 tools can't cope with a non-zero sized bss before linkage.
4220 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4222 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4223 throughout. That enum no longer means what we thought it meant.
4225 * tc-m68k.c (md_assemble, md_parse_option): Handle new
4226 "-mno-688[58]1" options.
4228 * tc-m68k.c: Added CPU32 support.
4230 Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4232 * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
4234 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4236 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
4237 Change LIBDEPS dependence to LIBS.
4239 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4241 * Makefile.in (install): if $(tooldir) exists, install as in
4244 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4246 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4247 .word is < -32768 or > 32767. The -J flag causes the error to be
4248 ignored. This is to catch over-sized switches generated by gcc on
4249 systems which don't support the broken .word hack.
4250 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4251 write.c (fixup_segment): check for signed .word overflow if
4252 WARN_SIGNED_OVERFLOW_WORD.
4254 * write.c (fixup_segment): fixed missing parens in expression
4255 checking for byte or word overflow.
4257 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
4258 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
4259 WARN_SIGNED_OVERFLOW_WORD.

4739 machine is a SPARC or a 29K.
4740 * config/obj-aout.c: added s_sect pseudo op
4741 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4742 fill in the timestamp.

4764 * symbols.c (local_label_name): symbols now start with ^A.
4766 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4767 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4768 generate these sections. .align: will use NOP_OPCODE or 0
4769 for padding. This is just for being nice to the
4772 * expr.c (operand): changed to generate local label "\001L0"
4773 starting with a ^A so that it is recognized as a local label.
4775 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4777 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4778 i/o opcodes - inb, inw, outb and outw. string manipulation with
4779 att syntax - scmp, slod, smov, ssca, ssto.
4781 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4782 to just after .file .
4784 In obj_crawl_symbol_chain() where it tries to put the external
4785 symbols apart, with the condition:
4786 (!S_IS_DEFINED(symbolP) &&
4787 !S_IS_DEBUG(symbolP) &&
4788 !SF_GET_STATICS(symbolP))
4789 it was moving too many symbols out. So I switch it back to the
4791 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4793 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4794 so that we don't use the F_RELFLG which make the linker complain
4795 that somebody has stripped the relocation info.
4797 Also, the AIX ld program require that the relocation table
4798 is sorted by r_vaddr like the standard ATT assembler does.
4800 [he also changed the sizeof(struct ...)'s into the coff
4801 style FOOSZ macros. I'm not sure this is right, but I can't
4802 remember why. xoxorich.]

4806 * Makefile.in, configure.in, doc: use the doc. Build it, install
4809 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4811 * read.c: white space and comments only.
4813 * configure.in: use the new atof-ns32.c for ns32k.
4815 * write.c: comment change only.
4817 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4818 aren't yet integrated.
4820 * tc-i860.[hc]: blew off the dust. Something must still be done
4821 about conflicting relocation types.
4823 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4826 * tc-i960.c, tc-sparc.c: white space and comments only.
4828 * tc-a29k.h: delete duplicate macro definition.
4830 * new file atof-ns32k.c copied from hack's last unreleased gas.
4832 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4834 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4837 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4838 ChangeLog's prior to this are sketchy at best. I have logs.
4839 They just aren't ChangeLogs.
