1386 of interest to the linker. ENTRY/EXIT relocations for SOM are
1387 an example of marker relocations.
1388 * write.c (write_relocs): Instead of assuming size of a relocation
1389 is 4 bytes, pick up the size from relocation itself.

1417 BFD_RELOC_MIPS_GPREL. Added new case a.
1418 (set_at, load_register, macro): Changed calls to macro_build to
1419 pass new argument for i, j and o cases.
1420 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require
1421 special handling when generating SVR4 PIC code.
1422 (mips_ip, tc_get_register, s_frame): Use macros FP, SP, GP and AT
1423 rather than hard coded constants.
1424 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

1754 for keeping or rejecting configurations still under development;
1755 default is to assume production environment, and reject configs
1756 still being worked on. Mark Elf configurations (except sparc and
1757 i386) as developmental. Deleted cases matching some generic names
1758 in favor of more specific names. (E.g., when we get Alpha

1775 through inclusion of tc-hppa.h. Delete all forward declarations
1776 for functions only used within tc-hppa.c, likewise for structures,
1777 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1778 conditional code in a few small places.
1780 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1781 structures, global variables, forward declarations together.

1783 conditional code -- try to group conditional code together
1784 into a few places. Make all functions and variables which
1785 are only used within tc-hppa.c static. PARAMize all functions.
1786 Add comments to functions. Delete unused functions, variables,
1787 #defines, etc. Delete unused members within structures. Delete
1788 ldil;ble hacks -- it is believed they were installed to work
1789 around old gas bugs. Avoid using mixed case for local
1790 functions, variables, and structures. Fix formatting problems
1791 not found by GNU-indent. Add FIXME notices for things which
1792 should be worked on the near future. Delete lots of old
1793 useless (1.36 PA-SOM) code.

1866 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
1868 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
1869 ELF, since the ELF object format does not have these type of
1870 relocations. Change the abort into as as_bad and return
1871 BFD_RELOC_NONE to silence compiler warnings.
1872 (md_assemble): Keep track of the instruction size. Allow white
1873 space between the $ and the constant for compatibility with older
1874 gases and other assemblers.
1875 (i386_operand): Skip spaces between $ and expression.

2822 Thu Jul 29 18:38:37 1993 david d `zoo' zuhn (zoo@rtl.cygnus.com)
2824 * config/ho-sunos.h: remove some old function decls that conflict
2825 w/ ANSI, and which weren't needed anyway
2827 Wed Jul 28 16:34:55 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
2829 * config/obj-elf.h (obj_frob_symbol): Renamed from tc_frob_symbol,

2871 are also magic, and have special default flag settings.
2872 (obj_elf_frob_symbol): Since the return value from this function

2936 * Extensive changes to permit symbols to contain any expression
2937 type and to delay the computation of the expression until the
2938 value is actually needed. This permits setting symbols to values
2939 calculated based on object code size. Expressions were changed to
2940 no longer be in a section, to stop the overloading of segment and
2941 expression type that previously occurred.
2943 * as.c (big_section, pass1_section, diff_section, absent_section):
2945 (expr_section): Added (used for dummy symbols which hold

3031 to pop back to it. Handle unquoted section name as well as quoted
3032 section name. Don't crash on invalid strings.

4259 process relocs if there aren't any relocs to process. Avoids
4260 malloc/free bug on SCO too.
4262 * as.h: Move local include files below system include files, to
4263 avoid some redefinition complaints on some systems.
4264 (const, volatile): Don't need these conditionally defined if we
4265 use CONST and VOLATILE from ansidecl.h.

4308 dropping a space immediately following an identifier.
4309 * expr.c, write.c: Rewrote assert expressions to not use multiple
4310 lines; I don't think that can be done portably.
4311 * config/tc-mips.c (macro): Use $AT if target register is zero in
4312 load instruction, which it can be for a floating point load.
4314 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

4386 prototypes for all static functions. Moved existing minimal
4387 debugging format support info #ifndef OBJ_ECOFF blocks.

4438 * read.c (s_ignore): Don't declare is_end_of_line. It's
4439 redundant, and triggers a VMS gcc compiler bug.
4441 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4442 current segment as an argument. (Ignored in all cases but VMS.)
4443 All callers and definitions changed.

4725 Wed Jan 20 17:11:53 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4727 * config/obj-coff.c (obj_emit_relocations): Don't use #elif.
4728 (obj_emit_lineno): Don't need return at end of void function.
4729 (obj_symbol_new_hook): Ditto.
4731 * config/tc-m68k.c: Removed some unused code.

4737 Fri Jan 8 05:44:49 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4739 * config/tc-sparc.c (architecture_requested, warn_on_bump,
4740 md_relax_table): Use default zero initialization.
4741 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4742 latter, instead of selecting with preprocessor conditionals.
4744 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4746 * configure.in: recognise all sparclite variants
4748 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4754 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4756 * expr.c (operand): If character other than comma or newline is a
4757 logical end-of-line character, use the newline case.
4758 From Eric Youngdale:
4759 (operand): Set X_add_number field for floating-point numbers.
4760 (operand): Treat zero byte as end-of-operand.
4762 * configure.in (per-target): Look for with_bfd_assembler option.
4763 For now, only accept "no", until the merge is done.
4765 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4766 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4767 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4768 * read.c: Finish conversion to S_* macros in the VMS only
4769 parts of the program. Add "const" modifier to hex_value.
4770 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4772 * expr.c: Add "const" modifier to hex_value.
4773 * symbols.c: Finish conversion to S_* macros in the VMS only
4774 parts of the program. Add "const" modifier to
4775 md_[long,short]_jump_size. Remove declaration of const_flag
4776 (which will be declared in obj-vms.h).
4777 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4778 Fix arguments to VMS_write_object_file.
4779 * config-gas.com: New file. Script for VMS systems to set up the
4780 configuration to build gas for VMS, and create config.status.
4781 * make-gas.com: Redone to work with new scheme.
4782 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4784 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4785 will swap bytes if needed on a big endian system. Use throughout
4787 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4788 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4789 types of malformed stabs. Change parsing algorithm so that we are
4790 more certain of having all of the information that we need on hand.
4791 * obj-vms.c (final_forward_reference): New function, used to help
4792 resolve the data types of as many struct elements as possible
4793 when some part of the struct is not fully defined by the compiler.
4794 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4796 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4797 as symbols as well in the object file. Look for external functions
4798 that start with "__vt.", and turn them into variables, since the
4799 g++ compiler is incapable of doing this.
4800 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4802 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4803 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4804 have the name of the source file yet.
4805 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4807 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4809 * read.c (s_data): Always use "data_section", since it'll map to
4810 SEG_DATA or SEG_E1 if needed.
4811 (s_lcomm): Likewise with bss_section.
4812 (s_fill): Use memset, not bzero.
4814 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)
4816 * read.c: Deleted some code under "#ifdef DONTDEF" that was for

4830 * as.h (stdoutput): New var, defined only if BFD_ASSEMBLER.
4831 (segT) [BFD_ASSEMBLER]: New typedef for "asection *".
4832 (segment_name) If BFD_ASSEMBLER, look up BFD section name;
4833 otherwise, use seg_name array.

4835 (section_alignment): Declare only if not BFD_ASSEMBLER.
4836 (big_section, reg_section, pass1_section, diff_section,
4837 absent_section, text_section, data_section, bss_section): If
4838 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4839 mapping to segT enum values.
4840 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4841 if these are used or defined, if BFD_ASSEMBLER.
4842 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4843 subseg_new split into two functions.
4844 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4846 * as.h (volatile): Don't define if already defined.
4847 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4849 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4850 declare with format attribute for -Wformat checking.
4852 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4854 * app.c, config/tc-*.c: Don't include read.h, since it is already
4857 * These are based on patches from Minh Tran-le
4858 <mtranle@paris.intellicorp.com>.
4859 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4860 obj_format coffbfd and gas_target i386coff for target.
4861 (i[34]86-*-isc*): New host (uses sysv).
4862 * config/i386aix.mt: Removed (no longer used).
4863 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4865 (LDFLAGS): Added, defined as -shlib.
4866 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4867 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4868 (DOT_LABEL_PREFIX): Define.
4869 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4870 name rather than L0\001.
4871 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4873 * symbols.c, symbols.h (local_bss_counter): Removed.
4874 * write.c (write_object_file): bss no longer uses
4875 local_bss_counter. Pass correct data and bss size to
4876 VMS_write_object_file.

4881 * config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
4882 (size_section): Restored sanity check.
4883 (do_relocs_for): Base section address on s_paddr rather than
4884 computing it. Adjust a29k R_IHIHALF special case to account for
4885 section paddr (used to require paddr to be zero). If there are no
4886 reclos, set s_relptr to 0. Set relocation size in object_headers.
4887 (fill_section): Always set s_vaddr here, removing
4888 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4889 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4890 Set STYP_INFO for .comment.
4891 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4892 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4894 H_{SET,GET}_* macros.
4895 (do_linenos_for): Set lineno size in object_headers.
4896 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4897 set s_vaddr here. If string_byte_count remains 4, set it back to
4898 0, and only write strings out if there are some. Call
4899 fill_section before do_relocs_for and do_linenos_for.
4900 (obj_coff_section): Handle optional quoted second argument giving
4901 section characteristics.
4902 (obj_coff_bss): Added to handle .bss.
4903 (obj_coff_ident): Added to handle .ident (puts string in .comment
4905 (obj_coff_lcomm): Put common symbols in .bss, not .data.
4906 (fixup_mdeps): Change to segment. Call frag_wane after
4908 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4909 adjustment (already happened only for common symbols, but this is
4911 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4912 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4923 (do_scrub_next_char): For \", return " not '.
4924 (symbol_chars): Now const.
4926 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4927 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4929 * config/obj-coff.h: Don't use #elif.
4931 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4932 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4934 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

4958 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4959 using ZERO_BASED_SEGMENTS.
4960 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4961 never set segment address for SEG_E2 (.bss) and don't write out
4962 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4963 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4964 definitions, and don't merge tags with non-tags. Check for .bf
4965 rather than just checking whether the second character is b and
4966 the third character is f.
4967 (obj_coff_val): gcc can generate values which we don't handle
4968 correctly; discard information for now, since it only affects the
4969 debugging information.
4970 (tag_find_or_name): Don't insert tags in the symbol table.
4971 (yank_symbols): Don't merge labels.
4972 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

5154 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
5155 constant will not fit in an immediate field.
5156 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

5191 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
5193 * Support for i386-sysv.
5194 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
5195 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
5196 be used to set them all to zero as was done before.
5197 (fill_section): segment addresses now set in write_object_file.
5198 (fill_section): Don't set STYP_NOLOAD for .bss section.
5199 (fixup_segment): 386 uses strange common symbol format.
5200 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
5201 compatibility with SVR3.2 linker.
5202 * configure.in: i386-sysv and i386-sco use coffbfd.
5204 * app.c (do_scrub_next_char): discard whitespace after a label.
5206 Sat Oct 10 12:33:45 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

5213 fix i960+non-bfd coff bit rot.
5214 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
5215 support for C source listings. (obj_coff_endef): look in the right
5216 part of the symbol for the symbol name
5218 * tc-m68k.c (get_num): make it work for all segments, not just the
5221 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
5223 * configure.in: recognize i386-*-bsd emulation.

5232 * tc-z8k.c: lots of bug fixes
5234 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
5236 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
5237 #elif, since it is not supported by old compilers.
5238 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
5239 couple of expressions in tc-m68k.c.
5241 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5243 * read.c (cons): If NO_RELOC is defined, use it.
5245 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
5247 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
5249 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
5250 local labels to start with a .) and set REGISTER_PREFIX to %.
5251 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

5267 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
5269 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
5270 sections starting from zero, rather than making them consecutive.
5271 This makes subsequent reloc calculations easier, esp if the object
5272 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
5273 allocate lcomm in .data rather than in .bss. It seems that some
5274 tools can't cope with a non-zero sized bss before linkage.
5276 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5278 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

5297 * Makefile.in (install): if $(tooldir) exists, install as in
5300 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
5302 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
5303 .word is < -32768 or > 32767. The -J flag causes the error to be
5304 ignored. This is to catch over-sized switches generated by gcc on
5305 systems which don't support the broken .word hack.
5306 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
5307 write.c (fixup_segment): check for signed .word overflow if
5308 WARN_SIGNED_OVERFLOW_WORD.
5310 * write.c (fixup_segment): fixed missing parens in expression
5311 checking for byte or word overflow.

5327 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
5329 * input-scrub.c (input_scrub_push): call input_file_begin, not
5331 messages.c (as_perror): print ": " between the passed in error and
5332 the strerror, like perror does.
5334 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
5336 * Makefile.in: use gas_target instead of modifying target_cpu.
5337 From Steve Chamberlain:
5338 Makefile.in: Handle m68*-*-coff*.
5339 read.c, read.h: add mult argument to s_space
5341 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
5342 Motorola and MIT syntax; gas can now assemble either type of
5344 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

5351 (fixup_segment) set fx_subsy to 0.
5352 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
5354 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
5357 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5359 * Makefile.in (LIBS): Include opcode library.

5384 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5386 * config/tc-m68k.c (init_table): Now const. Always include 68851
5387 data, so that "bc" is available to 68040 cache instructions.
5388 Added "tt0", "tt1", and 68ec030 variants.
5389 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5390 (enum _register): Added TT0, TT1.
5391 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5392 line number correctly in "internal error" messages. Don't print
5393 architecture-mismatch message for operand errors.
5395 From Colin Smith (colin@wrs.com):
5396 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather

5418 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5419 has already been formatted (but may still contain %-characters).
5422 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5424 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5425 written with indirection on the last two operands, which can be
5426 either data or address registers. Added a new operand type 'r'
5427 which accepts either register type. Added '(' to notend stuff in
5428 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5535 ancient or broken compilers.
5537 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5538 processor/opcode mismatch, so reword the error message.

5672 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5674 * write.c (write_object_file): For b.out format, round up section
5675 start addresses to match required alignment.
5677 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5679 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5680 where gcc looks for it.
5682 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5684 * Makefile.in: Changed some lines to be less confusing for some
5687 * input-file.c: Conditionalize on _IOFBF, not VMS.
5689 * read.c, write.c: Change a series of ifdef/elif to
5690 ifdef/else/ifdef etc.
5692 Fri Mar 27 12:21:16 1992 K. Richard Pixley (rich@cygnus.com)
5694 * symbols.c (fb_label_init): fix sizeof to memset.
5696 Fri Mar 13 15:45:44 1992 K. Richard Pixley (rich@cygnus.com)
5698 * Makefile.in: install the man page.
5700 * Makefile.in: pass down MAKEINFO explicitly on info.
5702 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
5704 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5706 * flonum-const.c: renamed flonum-konst.c to stop dos name
5709 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5711 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5712 tc-m68k.h to te-sun3.h.
5714 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5716 * configure.in: vxworks68 gets te-sun3.h.
5718 * expr.c: remove limitation that local_labels_dollar or
5719 local_labels_fb must be < 10.
5721 * symbols.c: remove local_labels_dollar, replace with a function
5722 interface for a sparse array. All users adjusted.
5724 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5726 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5728 * doc/Makefile.in: commented out line for building as-all.texinfo.
5731 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5733 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)
5735 * Makefile.in: added check target.
5737 Tue Mar 3 15:45:56 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5739 * Makefile.in: added tooldir and program_prefix.
5741 Sun Mar 1 04:43:19 1992 Michael Tiemann (tiemann@cygnus.com)
5743 * write.{c,h} (fix_new): Make these declarations consistent.
5745 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5747 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5750 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5752 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5754 * expr.c (operand): if can't work out what sort of operand it is,
5755 then look through FLT_CHARS for a hint.
5757 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5759 * Makefile.in, configure.in: removed traces of namesubdir,
5760 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5761 copyrights to '92, changed some from Cygnus to FSF.
5763 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5764 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5765 copyrights to '92, changed some from Cygnus to FSF.
5767 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5769 * expr.c: If an expression is single comma, then return with
5770 SEG_ABSENT rather than an error - since the sparc front end does
5771 really strange things with things like fbge,a
5773 * as.h: include bfd.h if using many sections
5774 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5775 local labels didn't work.
5776 * listing.c (list_symbol_table): don't core dump when there's no
5778 * write.c, write.h: call fix_new with the right number of args on
5780 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5783 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5785 * app.c: MRI compatibility - allow single quote to start a string.
5786 * as.c: fix typo recently introduced.
5787 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5788 * expr.c: Much rewriting, to accomodate MRI syntax for
5789 expressions. Also easier to read now.
5790 * listing.c: Put back defuns
5791 * read.c: modified to accept MRI syntax, put back listing pseudo
5792 ops so that an assembler built with NO_LISTING ignores list ops
5794 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5795 machine is a SPARC or a 29K.
5796 * config/obj-aout.c: added s_sect pseudo op
5797 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5798 fill in the timestamp.
5799 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5800 anymore, define all the relocs which the tc-<x> bit will use so we
5801 can translate from them to the coff types.
5802 * config/tc-a29k.c: reloc_type isn't ane enum any more
5803 * config/tc-m68k.c: Added NO_RELOC definition.
5805 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5807 * Makefile.in: put header files before C source for TAGS; remove
5808 references to non-existent syscalls.h.
5810 * read.c, write.c subsegs.c: back out the .bss changes.
5812 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5814 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5818 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5820 * symbols.c (local_label_name): symbols now start with ^A.
5822 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5823 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5824 generate these sections. .align: will use NOP_OPCODE or 0
5825 for padding. This is just for being nice to the
5828 * expr.c (operand): changed to generate local label "\001L0"
5829 starting with a ^A so that it is recognized as a local label.
5831 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5833 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5834 i/o opcodes - inb, inw, outb and outw. string manipulation with
5835 att syntax - scmp, slod, smov, ssca, ssto.
5837 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5838 to just after .file .
5840 In obj_crawl_symbol_chain() where it tries to put the external
5841 symbols apart, with the condition:
5842 (!S_IS_DEFINED(symbolP) &&
5843 !S_IS_DEBUG(symbolP) &&
5844 !SF_GET_STATICS(symbolP))
5845 it was moving too many symbols out. So I switch it back to the
5847 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5849 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5850 so that we don't use the F_RELFLG which make the linker complain
5851 that somebody has stripped the relocation info.
5853 Also, the AIX ld program require that the relocation table
5854 is sorted by r_vaddr like the standard ATT assembler does.
5856 [he also changed the sizeof(struct ...)'s into the coff
5857 style FOOSZ macros. I'm not sure this is right, but I can't
5858 remember why. xoxorich.]
5860 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5862 * Makefile.in, configure.in, doc: use the doc. Build it, install
5865 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5867 * read.c: white space and comments only.
5869 * configure.in: use the new atof-ns32.c for ns32k.
5871 * write.c: comment change only.
5873 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5874 aren't yet integrated.
5876 * tc-i860.[hc]: blew off the dust. Something must still be done
5877 about conflicting relocation types.
5879 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5882 * tc-i960.c, tc-sparc.c: white space and comments only.
5884 * tc-a29k.h: delete duplicate macro definition.
5886 * new file atof-ns32k.c copied from hack's last unreleased gas.
5888 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5890 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5893 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5894 ChangeLog's prior to this are sketchy at best. I have logs.
5895 They just aren't ChangeLogs.
