21 * Extensive changes to permit symbols to contain any expression
22 type and to delay the computation of the expression until the
23 value is actually needed. This permits setting symbols to values
24 calculated based on object code size. Expressions were changed to
25 no longer be in a section, to stop the overloading of segment and
26 expression type that previously occurred.

178 (macro): Call mips_emit_delays before setting mips_noreorder.
179 Increment and decrement mips_noreorder rather than using
180 save_reorder_condition. Don't bother to use noreorder in

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

1393 dropping a space immediately following an identifier.

1396 * config/tc-mips.c (macro): Use $AT if target register is zero in
1397 load instruction, which it can be for a floating point load.

1471 prototypes for all static functions. Moved existing minimal
1472 debugging format support info #ifndef OBJ_ECOFF blocks.

1523 * read.c (s_ignore): Don't declare is_end_of_line. It's
1524 redundant, and triggers a VMS gcc compiler bug.

1845 (operand): Treat zero byte as end-of-operand.
1847 * configure.in (per-target): Look for with_bfd_assembler option.
1848 For now, only accept "no", until the merge is done.
1850 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
1851 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

1857 * expr.c: Add "const" modifier to hex_value.
1858 * symbols.c: Finish conversion to S_* macros in the VMS only
1859 parts of the program. Add "const" modifier to
1860 md_[long,short]_jump_size. Remove declaration of const_flag
1861 (which will be declared in obj-vms.h).
1862 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1863 Fix arguments to VMS_write_object_file.
1864 * config-gas.com: New file. Script for VMS systems to set up the
1865 configuration to build gas for VMS, and create config.status.

1924 mapping to segT enum values.
1925 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
1926 if these are used or defined, if BFD_ASSEMBLER.
1927 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
1928 subseg_new split into two functions.
1929 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1931 * as.h (volatile): Don't define if already defined.

1951 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
1952 * config/te-sco386.h (LOCAL_LABEL): Don't define.
1953 (DOT_LABEL_PREFIX): Define.
1954 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
1955 name rather than L0\001.
1956 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
1958 * symbols.c, symbols.h (local_bss_counter): Removed.
1959 * write.c (write_object_file): bss no longer uses
1960 local_bss_counter. Pass correct data and bss size to
1961 VMS_write_object_file.

1967 (size_section): Restored sanity check.
1968 (do_relocs_for): Base section address on s_paddr rather than
1969 computing it. Adjust a29k R_IHIHALF special case to account for
1970 section paddr (used to require paddr to be zero). If there are no
1971 reclos, set s_relptr to 0. Set relocation size in object_headers.
1972 (fill_section): Always set s_vaddr here, removing
1973 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
1974 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
1975 Set STYP_INFO for .comment.

1980 (do_linenos_for): Set lineno size in object_headers.
1981 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1982 set s_vaddr here. If string_byte_count remains 4, set it back to
1983 0, and only write strings out if there are some. Call
1984 fill_section before do_relocs_for and do_linenos_for.
1985 (obj_coff_section): Handle optional quoted second argument giving
1986 section characteristics.
1987 (obj_coff_bss): Added to handle .bss.
1988 (obj_coff_ident): Added to handle .ident (puts string in .comment
1990 (obj_coff_lcomm): Put common symbols in .bss, not .data.
1991 (fixup_mdeps): Change to segment. Call frag_wane after
1993 (fixup_segment): Explicitly check S_IS_COMMON before making 386
1994 adjustment (already happened only for common symbols, but this is
1996 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.

2008 (do_scrub_next_char): For \", return " not '.
2009 (symbol_chars): Now const.
2011 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
2012 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
2014 * config/obj-coff.h: Don't use #elif.
2016 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
2017 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

2046 never set segment address for SEG_E2 (.bss) and don't write out
2047 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
2048 (obj_coff_endef): Don't merge labels or symbols awaiting forward
2049 definitions, and don't merge tags with non-tags. Check for .bf
2050 rather than just checking whether the second character is b and
2051 the third character is f.
2052 (obj_coff_val): gcc can generate values which we don't handle
2053 correctly; discard information for now, since it only affects the
2054 debugging information.

2056 (yank_symbols): Don't merge labels.
2057 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

2203 could be doing emulation.
2205 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
2208 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

2239 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
2240 constant will not fit in an immediate field.
2241 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

2276 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
2278 * Support for i386-sysv.
2279 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

2303 * tc-m68k.c (get_num): make it work for all segments, not just the
2306 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

2317 * tc-z8k.c: lots of bug fixes
2319 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
2321 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2322 #elif, since it is not supported by old compilers.
2323 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2324 couple of expressions in tc-m68k.c.
2326 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2328 * read.c (cons): If NO_RELOC is defined, use it.

2332 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
2334 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2335 local labels to start with a .) and set REGISTER_PREFIX to %.
2336 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2338 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

2349 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2352 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
2354 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2355 sections starting from zero, rather than making them consecutive.
2356 This makes subsequent reloc calculations easier, esp if the object
2357 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2358 allocate lcomm in .data rather than in .bss. It seems that some
2359 tools can't cope with a non-zero sized bss before linkage.
2361 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
2363 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2364 throughout. That enum no longer means what we thought it meant.

2367 "-mno-688[58]1" options.
2369 * tc-m68k.c: Added CPU32 support.

2377 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
2378 Change LIBDEPS dependence to LIBS.
2380 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
2382 * Makefile.in (install): if $(tooldir) exists, install as in
2385 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
2387 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2388 .word is < -32768 or > 32767. The -J flag causes the error to be
2389 ignored. This is to catch over-sized switches generated by gcc on
2390 systems which don't support the broken .word hack.
2391 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2392 write.c (fixup_segment): check for signed .word overflow if
2393 WARN_SIGNED_OVERFLOW_WORD.
2395 * write.c (fixup_segment): fixed missing parens in expression
2396 checking for byte or word overflow.
2398 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.

2410 * tc-i386.h : new coff defines
2412 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
2414 * input-scrub.c (input_scrub_push): call input_file_begin, not
2416 messages.c (as_perror): print ": " between the passed in error and
2417 the strerror, like perror does.
2419 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
2421 * Makefile.in: use gas_target instead of modifying target_cpu.
2422 From Steve Chamberlain:
2423 Makefile.in: Handle m68*-*-coff*.
2424 read.c, read.h: add mult argument to s_space
2426 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2427 Motorola and MIT syntax; gas can now assemble either type of
2429 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
2430 From Steve Chamberlain:
2431 m68kcoff.mt: for m68k COFF.
2432 obj-coffbfd.c: (fixup_mdeps) added
2433 (size_section) removed bad sanity check
2434 (fill_section) added rs_machine_dependent case

2509 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2510 written with indirection on the last two operands, which can be
2511 either data or address registers. Added a new operand type 'r'
2512 which accepts either register type. Added '(' to notend stuff in
2513 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

2852 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2854 * expr.c: If an expression is single comma, then return with
2855 SEG_ABSENT rather than an error - since the sparc front end does
2856 really strange things with things like fbge,a
2858 * as.h: include bfd.h if using many sections
2859 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2860 local labels didn't work.
2861 * listing.c (list_symbol_table): don't core dump when there's no
2863 * write.c, write.h: call fix_new with the right number of args on

2868 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2870 * app.c: MRI compatibility - allow single quote to start a string.
2871 * as.c: fix typo recently introduced.
2872 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2873 * expr.c: Much rewriting, to accomodate MRI syntax for
2874 expressions. Also easier to read now.
2875 * listing.c: Put back defuns
2876 * read.c: modified to accept MRI syntax, put back listing pseudo
2877 ops so that an assembler built with NO_LISTING ignores list ops
2879 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2880 machine is a SPARC or a 29K.
2881 * config/obj-aout.c: added s_sect pseudo op
2882 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2883 fill in the timestamp.
2884 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2885 anymore, define all the relocs which the tc-<x> bit will use so we
2886 can translate from them to the coff types.
2887 * config/tc-a29k.c: reloc_type isn't ane enum any more
2888 * config/tc-m68k.c: Added NO_RELOC definition.
2890 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
2892 * Makefile.in: put header files before C source for TAGS; remove
2893 references to non-existent syscalls.h.
2895 * read.c, write.c subsegs.c: back out the .bss changes.
2897 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2899 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2903 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
2905 * symbols.c (local_label_name): symbols now start with ^A.
2907 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2908 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2909 generate these sections. .align: will use NOP_OPCODE or 0
2910 for padding. This is just for being nice to the
2913 * expr.c (operand): changed to generate local label "\001L0"
2914 starting with a ^A so that it is recognized as a local label.
2916 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2918 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2919 i/o opcodes - inb, inw, outb and outw. string manipulation with
2920 att syntax - scmp, slod, smov, ssca, ssto.
2922 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2923 to just after .file .
2925 In obj_crawl_symbol_chain() where it tries to put the external
2926 symbols apart, with the condition:
2927 (!S_IS_DEFINED(symbolP) &&
2928 !S_IS_DEBUG(symbolP) &&
2929 !SF_GET_STATICS(symbolP))
2930 it was moving too many symbols out. So I switch it back to the
2932 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2934 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2935 so that we don't use the F_RELFLG which make the linker complain
2936 that somebody has stripped the relocation info.
2938 Also, the AIX ld program require that the relocation table
2939 is sorted by r_vaddr like the standard ATT assembler does.
2941 [he also changed the sizeof(struct ...)'s into the coff
2942 style FOOSZ macros. I'm not sure this is right, but I can't
2943 remember why. xoxorich.]

2947 * Makefile.in, configure.in, doc: use the doc. Build it, install
2950 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2952 * read.c: white space and comments only.
2954 * configure.in: use the new atof-ns32.c for ns32k.
2956 * write.c: comment change only.
2958 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2959 aren't yet integrated.
2961 * tc-i860.[hc]: blew off the dust. Something must still be done
2962 about conflicting relocation types.
2964 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2967 * tc-i960.c, tc-sparc.c: white space and comments only.
2969 * tc-a29k.h: delete duplicate macro definition.
2971 * new file atof-ns32k.c copied from hack's last unreleased gas.
2973 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2975 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2978 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2979 ChangeLog's prior to this are sketchy at best. I have logs.
2980 They just aren't ChangeLogs.
