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

854 conditional code -- try to group conditional code together
855 into a few places. Make all functions and variables which
856 are only used within tc-hppa.c static. PARAMize all functions.
857 Add comments to functions. Delete unused functions, variables,
858 #defines, etc. Delete unused members within structures. Delete
859 ldil;ble hacks -- it is believed they were installed to work
860 around old gas bugs. Avoid using mixed case for local
861 functions, variables, and structures. Fix formatting problems
862 not found by GNU-indent. Add FIXME notices for things which
863 should be worked on the near future. Delete lots of old

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

937 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
939 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
940 ELF, since the ELF object format does not have these type of
941 relocations. Change the abort into as as_bad and return
942 BFD_RELOC_NONE to silence compiler warnings.
943 (md_assemble): Keep track of the instruction size. Allow white
944 space between the $ and the constant for compatibility with older
945 gases and other assemblers.
946 (i386_operand): Skip spaces between $ and expression.
947 (tc_gen_reloc): Don't allow anything but 32 bit relocations on

1942 are also magic, and have special default flag settings.
1943 (obj_elf_frob_symbol): Since the return value from this function

2007 * Extensive changes to permit symbols to contain any expression
2008 type and to delay the computation of the expression until the
2009 value is actually needed. This permits setting symbols to values
2010 calculated based on object code size. Expressions were changed to
2011 no longer be in a section, to stop the overloading of segment and
2012 expression type that previously occurred.
2014 * as.c (big_section, pass1_section, diff_section, absent_section):
2016 (expr_section): Added (used for dummy symbols which hold

2100 (previous_section, previous_subsection): New vars.
2101 (obj_elf_section): Save current place in case DWARF code wants us

3334 avoid some redefinition complaints on some systems.
3335 (const, volatile): Don't need these conditionally defined if we
3336 use CONST and VOLATILE from ansidecl.h.

3379 dropping a space immediately following an identifier.
3380 * expr.c, write.c: Rewrote assert expressions to not use multiple
3381 lines; I don't think that can be done portably.
3382 * config/tc-mips.c (macro): Use $AT if target register is zero in
3383 load instruction, which it can be for a floating point load.
3385 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3457 prototypes for all static functions. Moved existing minimal
3458 debugging format support info #ifndef OBJ_ECOFF blocks.

3509 * read.c (s_ignore): Don't declare is_end_of_line. It's
3510 redundant, and triggers a VMS gcc compiler bug.
3512 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
3513 current segment as an argument. (Ignored in all cases but VMS.)
3514 All callers and definitions changed.

3796 Wed Jan 20 17:11:53 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3798 * config/obj-coff.c (obj_emit_relocations): Don't use #elif.
3799 (obj_emit_lineno): Don't need return at end of void function.
3800 (obj_symbol_new_hook): Ditto.
3802 * config/tc-m68k.c: Removed some unused code.
3803 (tc_aout_fix_to_chars): Array nbytes_r_length is now const.

3808 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3810 * config/tc-sparc.c (architecture_requested, warn_on_bump,
3811 md_relax_table): Use default zero initialization.
3812 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
3813 latter, instead of selecting with preprocessor conditionals.
3815 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
3817 * configure.in: recognise all sparclite variants
3819 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3821 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
3822 accidentally changed to use subseg_change where it should have
3825 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
3827 * expr.c (operand): If character other than comma or newline is a
3828 logical end-of-line character, use the newline case.
3829 From Eric Youngdale:
3830 (operand): Set X_add_number field for floating-point numbers.
3831 (operand): Treat zero byte as end-of-operand.
3833 * configure.in (per-target): Look for with_bfd_assembler option.
3834 For now, only accept "no", until the merge is done.
3836 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
3837 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
3838 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
3839 * read.c: Finish conversion to S_* macros in the VMS only
3840 parts of the program. Add "const" modifier to hex_value.
3841 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
3843 * expr.c: Add "const" modifier to hex_value.
3844 * symbols.c: Finish conversion to S_* macros in the VMS only
3845 parts of the program. Add "const" modifier to
3846 md_[long,short]_jump_size. Remove declaration of const_flag
3847 (which will be declared in obj-vms.h).
3848 * write.c: Add "const" modifier to md_[long,short]_jump_size.
3849 Fix arguments to VMS_write_object_file.
3850 * config-gas.com: New file. Script for VMS systems to set up the
3851 configuration to build gas for VMS, and create config.status.
3852 * make-gas.com: Redone to work with new scheme.
3853 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
3855 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
3856 will swap bytes if needed on a big endian system. Use throughout
3858 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
3859 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
3860 types of malformed stabs. Change parsing algorithm so that we are
3861 more certain of having all of the information that we need on hand.
3862 * obj-vms.c (final_forward_reference): New function, used to help
3863 resolve the data types of as many struct elements as possible
3864 when some part of the struct is not fully defined by the compiler.
3865 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
3867 * obj-vms.c (VMS_write_object_file): Define all vtable psects
3868 as symbols as well in the object file. Look for external functions
3869 that start with "__vt.", and turn them into variables, since the
3870 g++ compiler is incapable of doing this.
3871 * tc-vax.c: Add '1' option for backward compatibility with older GCC
3873 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
3874 * input-scrub.c (as_where): Fix bug where as would crash if we did not
3875 have the name of the source file yet.
3876 * config/ho-vms.h: define HO_VMS, not HO_VAX.
3878 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
3880 * read.c (s_data): Always use "data_section", since it'll map to
3881 SEG_DATA or SEG_E1 if needed.
3882 (s_lcomm): Likewise with bss_section.
3883 (s_fill): Use memset, not bzero.
3885 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
3887 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

3901 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
3902 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
3903 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
3904 otherwise, use seg_name array.
3905 (seg_name): Declare only if not BFD_ASSEMBLER.
3906 (section_alignment): Declare only if not BFD_ASSEMBLER.
3907 (big_section, reg_section, pass1_section, diff_section,
3908 absent_section, text_section, data_section, bss_section): If
3909 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
3910 mapping to segT enum values.
3911 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
3912 if these are used or defined, if BFD_ASSEMBLER.
3913 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
3914 subseg_new split into two functions.
3915 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
3917 * as.h (volatile): Don't define if already defined.
3918 (had_errors, had_warnings): Provide prototypes for ANSI C even if
3920 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
3921 declare with format attribute for -Wformat checking.
3923 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
3925 * app.c, config/tc-*.c: Don't include read.h, since it is already
3928 * These are based on patches from Minh Tran-le
3929 <mtranle@paris.intellicorp.com>.
3930 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
3931 obj_format coffbfd and gas_target i386coff for target.
3932 (i[34]86-*-isc*): New host (uses sysv).
3933 * config/i386aix.mt: Removed (no longer used).
3934 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
3936 (LDFLAGS): Added, defined as -shlib.
3937 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
3938 * config/te-sco386.h (LOCAL_LABEL): Don't define.
3939 (DOT_LABEL_PREFIX): Define.
3940 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
3941 name rather than L0\001.
3942 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
3944 * symbols.c, symbols.h (local_bss_counter): Removed.
3945 * write.c (write_object_file): bss no longer uses
3946 local_bss_counter. Pass correct data and bss size to
3947 VMS_write_object_file.

3952 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
3953 (size_section): Restored sanity check.
3954 (do_relocs_for): Base section address on s_paddr rather than
3955 computing it. Adjust a29k R_IHIHALF special case to account for
3956 section paddr (used to require paddr to be zero). If there are no
3957 reclos, set s_relptr to 0. Set relocation size in object_headers.
3958 (fill_section): Always set s_vaddr here, removing
3959 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
3960 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
3961 Set STYP_INFO for .comment.
3962 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
3963 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

3965 H_{SET,GET}_* macros.
3966 (do_linenos_for): Set lineno size in object_headers.
3967 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
3968 set s_vaddr here. If string_byte_count remains 4, set it back to
3969 0, and only write strings out if there are some. Call
3970 fill_section before do_relocs_for and do_linenos_for.
3971 (obj_coff_section): Handle optional quoted second argument giving
3972 section characteristics.
3973 (obj_coff_bss): Added to handle .bss.
3974 (obj_coff_ident): Added to handle .ident (puts string in .comment

3977 (fixup_mdeps): Change to segment. Call frag_wane after
3979 (fixup_segment): Explicitly check S_IS_COMMON before making 386
3980 adjustment (already happened only for common symbols, but this is
3982 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

3994 (do_scrub_next_char): For \", return " not '.
3995 (symbol_chars): Now const.
3997 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
3998 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4000 * config/obj-coff.h: Don't use #elif.
4002 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4003 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4005 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4029 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4030 using ZERO_BASED_SEGMENTS.
4031 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4032 never set segment address for SEG_E2 (.bss) and don't write out
4033 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4034 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4035 definitions, and don't merge tags with non-tags. Check for .bf
4036 rather than just checking whether the second character is b and
4037 the third character is f.
4038 (obj_coff_val): gcc can generate values which we don't handle
4039 correctly; discard information for now, since it only affects the
4040 debugging information.
4041 (tag_find_or_name): Don't insert tags in the symbol table.
4042 (yank_symbols): Don't merge labels.
4043 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4225 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4226 constant will not fit in an immediate field.
4227 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

4266 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4267 be used to set them all to zero as was done before.
4268 (fill_section): segment addresses now set in write_object_file.
4269 (fill_section): Don't set STYP_NOLOAD for .bss section.
4270 (fixup_segment): 386 uses strange common symbol format.
4271 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4272 compatibility with SVR3.2 linker.
4273 * configure.in: i386-sysv and i386-sco use coffbfd.

4285 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4286 support for C source listings. (obj_coff_endef): look in the right
4287 part of the symbol for the symbol name
4289 * tc-m68k.c (get_num): make it work for all segments, not just the
4292 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

4303 * tc-z8k.c: lots of bug fixes
4305 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4307 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4308 #elif, since it is not supported by old compilers.
4309 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4310 couple of expressions in tc-m68k.c.
4312 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4314 * read.c (cons): If NO_RELOC is defined, use it.
4316 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4318 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4320 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4321 local labels to start with a .) and set REGISTER_PREFIX to %.
4322 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4340 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4341 sections starting from zero, rather than making them consecutive.
4342 This makes subsequent reloc calculations easier, esp if the object
4343 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4344 allocate lcomm in .data rather than in .bss. It seems that some
4345 tools can't cope with a non-zero sized bss before linkage.
4347 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4349 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

4371 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4373 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4374 .word is < -32768 or > 32767. The -J flag causes the error to be
4375 ignored. This is to catch over-sized switches generated by gcc on
4376 systems which don't support the broken .word hack.
4377 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4378 write.c (fixup_segment): check for signed .word overflow if
4379 WARN_SIGNED_OVERFLOW_WORD.

4398 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4400 * input-scrub.c (input_scrub_push): call input_file_begin, not
4402 messages.c (as_perror): print ": " between the passed in error and
4403 the strerror, like perror does.
4405 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4408 From Steve Chamberlain:
4409 Makefile.in: Handle m68*-*-coff*.
4410 read.c, read.h: add mult argument to s_space
4412 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4413 Motorola and MIT syntax; gas can now assemble either type of
4415 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4422 (fixup_segment) set fx_subsy to 0.
4423 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4425 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4428 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4430 * Makefile.in (LIBS): Include opcode library.

4455 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4457 * config/tc-m68k.c (init_table): Now const. Always include 68851
4458 data, so that "bc" is available to 68040 cache instructions.
4459 Added "tt0", "tt1", and 68ec030 variants.
4460 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4461 (enum _register): Added TT0, TT1.
4462 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4463 line number correctly in "internal error" messages. Don't print
4464 architecture-mismatch message for operand errors.
4466 From Colin Smith (colin@wrs.com):
4467 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

4489 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
4490 has already been formatted (but may still contain %-characters).
4493 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
4495 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
4496 written with indirection on the last two operands, which can be
4497 either data or address registers. Added a new operand type 'r'
4498 which accepts either register type. Added '(' to notend stuff in
4499 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

4748 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
4750 * Makefile.in (install): Install into $(tooldir)/bin, since that's
4751 where gcc looks for it.
4753 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
4755 * Makefile.in: Changed some lines to be less confusing for some
4758 * input-file.c: Conditionalize on _IOFBF, not VMS.
4760 * read.c, write.c: Change a series of ifdef/elif to
4761 ifdef/else/ifdef etc.
4763 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
4765 * symbols.c (fb_label_init): fix sizeof to memset.
4767 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
4769 * Makefile.in: install the man page.
4771 * Makefile.in: pass down MAKEINFO explicitly on info.
4773 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
4775 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4777 * flonum-const.c: renamed flonum-konst.c to stop dos name
4780 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
4782 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
4783 tc-m68k.h to te-sun3.h.
4785 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
4787 * configure.in: vxworks68 gets te-sun3.h.
4789 * expr.c: remove limitation that local_labels_dollar or
4790 local_labels_fb must be < 10.
4792 * symbols.c: remove local_labels_dollar, replace with a function
4793 interface for a sparse array. All users adjusted.
4795 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
4797 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4799 * doc/Makefile.in: commented out line for building as-all.texinfo.
4802 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
4804 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
4806 * Makefile.in: added check target.
4808 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4810 * Makefile.in: added tooldir and program_prefix.
4812 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
4814 * write.{c,h} (fix_new): Make these declarations consistent.
4816 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
4818 * Makefile.in (strerror.o): Add rule so that broken Sun make can
4821 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
4823 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
4825 * expr.c (operand): if can't work out what sort of operand it is,
4826 then look through FLT_CHARS for a hint.
4828 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
4830 * Makefile.in, configure.in: removed traces of namesubdir,
4831 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4832 copyrights to '92, changed some from Cygnus to FSF.
4834 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
4835 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
4836 copyrights to '92, changed some from Cygnus to FSF.
4838 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4840 * expr.c: If an expression is single comma, then return with
4841 SEG_ABSENT rather than an error - since the sparc front end does
4842 really strange things with things like fbge,a
4844 * as.h: include bfd.h if using many sections
4845 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
4846 local labels didn't work.
4847 * listing.c (list_symbol_table): don't core dump when there's no
4849 * write.c, write.h: call fix_new with the right number of args on
4851 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
4854 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
4856 * app.c: MRI compatibility - allow single quote to start a string.
4857 * as.c: fix typo recently introduced.
4858 * as.h : Don't include aout/reloc.h - it's not right for COFF!
4859 * expr.c: Much rewriting, to accomodate MRI syntax for
4860 expressions. Also easier to read now.
4861 * listing.c: Put back defuns
4862 * read.c: modified to accept MRI syntax, put back listing pseudo
4863 ops so that an assembler built with NO_LISTING ignores list ops
4865 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
4866 machine is a SPARC or a 29K.
4867 * config/obj-aout.c: added s_sect pseudo op
4868 * config/obj-coffbfd.c: lints, set the filehdr flags right and
4869 fill in the timestamp.
4870 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
4871 anymore, define all the relocs which the tc-<x> bit will use so we
4872 can translate from them to the coff types.
4873 * config/tc-a29k.c: reloc_type isn't ane enum any more
4874 * config/tc-m68k.c: Added NO_RELOC definition.
4876 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
4878 * Makefile.in: put header files before C source for TAGS; remove
4879 references to non-existent syscalls.h.
4881 * read.c, write.c subsegs.c: back out the .bss changes.
4883 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
4885 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
4889 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
4891 * symbols.c (local_label_name): symbols now start with ^A.
4893 * read.c, subsegs.c, write.c obj-coff.c: added handling of
4894 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
4895 generate these sections. .align: will use NOP_OPCODE or 0
4896 for padding. This is just for being nice to the
4899 * expr.c (operand): changed to generate local label "\001L0"
4900 starting with a ^A so that it is recognized as a local label.
4902 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
4904 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
4905 i/o opcodes - inb, inw, outb and outw. string manipulation with
4906 att syntax - scmp, slod, smov, ssca, ssto.
4908 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
4909 to just after .file .
4911 In obj_crawl_symbol_chain() where it tries to put the external
4912 symbols apart, with the condition:
4913 (!S_IS_DEFINED(symbolP) &&
4914 !S_IS_DEBUG(symbolP) &&
4915 !SF_GET_STATICS(symbolP))
4916 it was moving too many symbols out. So I switch it back to the
4918 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
4920 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
4921 so that we don't use the F_RELFLG which make the linker complain
4922 that somebody has stripped the relocation info.
4924 Also, the AIX ld program require that the relocation table
4925 is sorted by r_vaddr like the standard ATT assembler does.
4927 [he also changed the sizeof(struct ...)'s into the coff
4928 style FOOSZ macros. I'm not sure this is right, but I can't
4929 remember why. xoxorich.]
4931 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
4933 * Makefile.in, configure.in, doc: use the doc. Build it, install
4936 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
4938 * read.c: white space and comments only.
4940 * configure.in: use the new atof-ns32.c for ns32k.
4942 * write.c: comment change only.
4944 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
4945 aren't yet integrated.
4947 * tc-i860.[hc]: blew off the dust. Something must still be done
4948 about conflicting relocation types.
4950 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
4953 * tc-i960.c, tc-sparc.c: white space and comments only.
4955 * tc-a29k.h: delete duplicate macro definition.
4957 * new file atof-ns32k.c copied from hack's last unreleased gas.
4959 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
4961 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
4964 * nearly everything. flush ChangeLog, package as gas-1.92.1.
4965 ChangeLog's prior to this are sketchy at best. I have logs.
4966 They just aren't ChangeLogs.
