986 messages and only print them when "print_errors" is true. Handle
987 empty string case like the HP assembler -- assume a value of
990 * config/ho-hpux.h: Do not include ho-sysv.h. Instead include
991 standard hpux include files to pick up various function decls.

1059 pass new argument for i, j and o cases.
1060 (macro): Handle M_JAL_1, M_JAL_2 and M_JAL_A. These require

1063 rather than hard coded constants.
1064 (md_apply_fix): Handle BFD_RELOC_MIPS_LITERAL and

1281 * config/tc-a29k.c (md_begin): When opcodes are mashed together in
1282 the table, require that the one without bit 0x1000000 set come

1394 for keeping or rejecting configurations still under development;
1395 default is to assume production environment, and reject configs
1396 still being worked on. Mark Elf configurations (except sparc and
1397 i386) as developmental. Deleted cases matching some generic names
1398 in favor of more specific names. (E.g., when we get Alpha
1399 support, we'll still only support VMS for Vax.)

1402 * config/tc-sparc.c (md_end): Function deleted.
1403 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

1413 against placing additional object-file dependent code here. Warn
1414 against contaminating all of GAS with the internals of tc-hppa.c
1415 through inclusion of tc-hppa.h. Delete all forward declarations
1416 for functions only used within tc-hppa.c, likewise for structures,
1417 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1418 conditional code in a few small places.
1420 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
1421 structures, global variables, forward declarations together.

1423 conditional code -- try to group conditional code together
1424 into a few places. Make all functions and variables which
1425 are only used within tc-hppa.c static. PARAMize all functions.
1426 Add comments to functions. Delete unused functions, variables,
1427 #defines, etc. Delete unused members within structures. Delete
1428 ldil;ble hacks -- it is believed they were installed to work
1429 around old gas bugs. Avoid using mixed case for local
1430 functions, variables, and structures. Fix formatting problems
1431 not found by GNU-indent. Add FIXME notices for things which
1432 should be worked on the near future. Delete lots of old
1433 useless (1.36 PA-SOM) code.
1435 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
1436 field of the fixS structure. Needed to build unwind
1437 descriptors correctly.

1445 which do not involve function symbols.
1447 * config/tc-hppa.h: Reindent with GNU-indent. Delete references
1448 to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused

2576 * Extensive changes to permit symbols to contain any expression
2577 type and to delay the computation of the expression until the
2578 value is actually needed. This permits setting symbols to values
2579 calculated based on object code size. Expressions were changed to
2580 no longer be in a section, to stop the overloading of segment and
2581 expression type that previously occurred.
2583 * as.c (big_section, pass1_section, diff_section, absent_section):

3789 than ECOFF line number information.
3790 (obj_ecoff_stab): Accept non-zero values for stabs line number.

3851 dependencies are read, not when they are used).
3853 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3854 a29k .bss section; the mondfe program doesn't like it.

3899 process relocs if there aren't any relocs to process. Avoids
3900 malloc/free bug on SCO too.
3902 * as.h: Move local include files below system include files, to
3903 avoid some redefinition complaints on some systems.
3904 (const, volatile): Don't need these conditionally defined if we
3905 use CONST and VOLATILE from ansidecl.h.
3906 (seg_name): Use CONST, not const.
3908 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3910 * config/tc-mips.c: Reindented to GNU standards.

3914 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3915 (fixup_segment): Add a29k special case; the linker is not prepared
3916 to see a segment offset here.
3918 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3921 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3923 * Makefile.in: add dvi target; as-$(config).texinfo might live in
3924 srcdir, might be in objdir.

3943 * Makefile.in (targ-cpu.o): Depend on config.h.
3945 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3947 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3948 dropping a space immediately following an identifier.
3949 * expr.c, write.c: Rewrote assert expressions to not use multiple
3950 lines; I don't think that can be done portably.
3951 * config/tc-mips.c (macro): Use $AT if target register is zero in
3952 load instruction, which it can be for a floating point load.
3954 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3975 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3977 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3978 to be on a single line.
3980 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4026 prototypes for all static functions. Moved existing minimal
4027 debugging format support info #ifndef OBJ_ECOFF blocks.

4030 all callers accordingly.
4031 (tc_get_register): Renamed from get_register, and made non-static.
4033 * config/mips-big.mt, config/mips-lit.mt: New files. Define

4076 * make-gas.com: Find obstack.obj if it's not in the current
4078 * read.c (s_ignore): Don't declare is_end_of_line. It's
4079 redundant, and triggers a VMS gcc compiler bug.
4081 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4082 current segment as an argument. (Ignored in all cases but VMS.)
4083 All callers and definitions changed.

4212 * read.c: Don't include ctype.h.
4213 (cons) [BFD_ASSEMBLER]: For undefined symbols, use BFD_RELOC_32
4214 for now; should be machine-dependent.
4216 * configure.in: Accept *-*-elf and *-*-solaris* as ELF format
4217 targets, forcing BFD use.

4221 * config/tc-sparc.c: Use PARAMS macro for static function
4222 declarations. Use BFD_RELOC_ macros everywhere, with
4223 compatibility macros declared for non-BFD mode.

4380 md_relax_table): Use default zero initialization.
4381 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4382 latter, instead of selecting with preprocessor conditionals.
4384 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

4396 * expr.c (operand): If character other than comma or newline is a
4397 logical end-of-line character, use the newline case.
4398 From Eric Youngdale:
4399 (operand): Set X_add_number field for floating-point numbers.
4400 (operand): Treat zero byte as end-of-operand.
4402 * configure.in (per-target): Look for with_bfd_assembler option.
4403 For now, only accept "no", until the merge is done.
4405 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4406 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

4412 * expr.c: Add "const" modifier to hex_value.
4413 * symbols.c: Finish conversion to S_* macros in the VMS only
4414 parts of the program. Add "const" modifier to
4415 md_[long,short]_jump_size. Remove declaration of const_flag
4416 (which will be declared in obj-vms.h).
4417 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4418 Fix arguments to VMS_write_object_file.
4419 * config-gas.com: New file. Script for VMS systems to set up the
4420 configuration to build gas for VMS, and create config.status.
4421 * make-gas.com: Redone to work with new scheme.
4422 * obj-vms.c: Patch to fix bug where we were not correctly parsing the

4427 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4428 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4429 types of malformed stabs. Change parsing algorithm so that we are
4430 more certain of having all of the information that we need on hand.
4431 * obj-vms.c (final_forward_reference): New function, used to help
4432 resolve the data types of as many struct elements as possible
4433 when some part of the struct is not fully defined by the compiler.

4436 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4437 as symbols as well in the object file. Look for external functions

4439 g++ compiler is incapable of doing this.
4440 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4442 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4443 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4444 have the name of the source file yet.
4445 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4447 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4449 * read.c (s_data): Always use "data_section", since it'll map to
4450 SEG_DATA or SEG_E1 if needed.
4451 (s_lcomm): Likewise with bss_section.
4452 (s_fill): Use memset, not bzero.
4454 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4475 (section_alignment): Declare only if not BFD_ASSEMBLER.
4476 (big_section, reg_section, pass1_section, diff_section,
4477 absent_section, text_section, data_section, bss_section): If
4478 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4479 mapping to segT enum values.
4480 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4481 if these are used or defined, if BFD_ASSEMBLER.
4482 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4483 subseg_new split into two functions.
4484 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4486 * as.h (volatile): Don't define if already defined.
4487 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4489 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4490 declare with format attribute for -Wformat checking.
4492 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4494 * app.c, config/tc-*.c: Don't include read.h, since it is already
4497 * These are based on patches from Minh Tran-le
4498 <mtranle@paris.intellicorp.com>.
4499 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4500 obj_format coffbfd and gas_target i386coff for target.
4501 (i[34]86-*-isc*): New host (uses sysv).
4502 * config/i386aix.mt: Removed (no longer used).
4503 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4505 (LDFLAGS): Added, defined as -shlib.
4506 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4507 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4508 (DOT_LABEL_PREFIX): Define.
4509 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4510 name rather than L0\001.

4513 * symbols.c, symbols.h (local_bss_counter): Removed.
4514 * write.c (write_object_file): bss no longer uses

4522 (size_section): Restored sanity check.
4523 (do_relocs_for): Base section address on s_paddr rather than
4524 computing it. Adjust a29k R_IHIHALF special case to account for
4525 section paddr (used to require paddr to be zero). If there are no
4526 reclos, set s_relptr to 0. Set relocation size in object_headers.
4527 (fill_section): Always set s_vaddr here, removing
4528 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4529 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4530 Set STYP_INFO for .comment.
4531 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4532 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4534 H_{SET,GET}_* macros.
4535 (do_linenos_for): Set lineno size in object_headers.
4536 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4537 set s_vaddr here. If string_byte_count remains 4, set it back to
4538 0, and only write strings out if there are some. Call
4539 fill_section before do_relocs_for and do_linenos_for.
4540 (obj_coff_section): Handle optional quoted second argument giving
4541 section characteristics.
4542 (obj_coff_bss): Added to handle .bss.
4543 (obj_coff_ident): Added to handle .ident (puts string in .comment

4563 (do_scrub_next_char): For \", return " not '.
4564 (symbol_chars): Now const.
4566 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4567 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4569 * config/obj-coff.h: Don't use #elif.
4571 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4572 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4574 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4576 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4598 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4599 using ZERO_BASED_SEGMENTS.
4600 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4601 never set segment address for SEG_E2 (.bss) and don't write out
4602 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4603 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4604 definitions, and don't merge tags with non-tags. Check for .bf
4605 rather than just checking whether the second character is b and
4606 the third character is f.
4607 (obj_coff_val): gcc can generate values which we don't handle
4608 correctly; discard information for now, since it only affects the
4609 debugging information.

4611 (yank_symbols): Don't merge labels.
4612 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4667 options. Updated options documentation for m68k. Some minor
4668 wording/punctuation changes.

4722 xrealloc from xrealloc.c.
4723 * xrealloc.c: Deleted.
4724 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
4726 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
4729 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
4731 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;
4732 don't initialize it with NULL.

4750 * all files: Whitespace changes for GNU indentation style, done by
4751 GNU `indent'. Some cleanup still needed, especially of comments.
4753 * configure.in: No te-386bsd.h file exists; don't try to use it.
4755 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
4757 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
4758 could be doing emulation.
4760 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
4763 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:

4790 consistently const, and always initialized them. Included read.h.
4792 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4794 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4795 constant will not fit in an immediate field.
4796 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4798 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4800 * obj-coff.c (callj_table): Delete global variable.

4807 * obj-coff.c: Replaced ANSI and non-ANSI function declarations
4808 with a single set using PARAMS macro.
4810 * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length

4815 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4816 so widening works consistently.
4818 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4820 * version.c: Put conditional "const" before version_string, not
4821 before dummy function for VMS. Now version 1.91.03.
4823 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4824 printed rep of null character.
4826 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4828 * obj-coffbfd.c (write_object_file): check return value of
4831 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4833 * Support for i386-sysv.
4834 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4835 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4836 be used to set them all to zero as was done before.
4837 (fill_section): segment addresses now set in write_object_file.
4838 (fill_section): Don't set STYP_NOLOAD for .bss section.
4839 (fixup_segment): 386 uses strange common symbol format.
4840 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4841 compatibility with SVR3.2 linker.
4842 * configure.in: i386-sysv and i386-sco use coffbfd.
4844 * app.c (do_scrub_next_char): discard whitespace after a label.

4858 * tc-m68k.c (get_num): make it work for all segments, not just the
4861 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
4863 * configure.in: recognize i386-*-bsd emulation.

4872 * tc-z8k.c: lots of bug fixes
4874 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4876 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4877 #elif, since it is not supported by old compilers.
4878 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4879 couple of expressions in tc-m68k.c.
4881 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4883 * read.c (cons): If NO_RELOC is defined, use it.
4885 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4887 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4889 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4890 local labels to start with a .) and set REGISTER_PREFIX to %.
4891 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
4893 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)

4904 * listing.c (debugging_pseudo): Add stabs and stabn as things to
4907 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
4909 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4910 sections starting from zero, rather than making them consecutive.
4911 This makes subsequent reloc calculations easier, esp if the object
4912 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4913 allocate lcomm in .data rather than in .bss. It seems that some
4914 tools can't cope with a non-zero sized bss before linkage.
4916 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4918 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4919 throughout. That enum no longer means what we thought it meant.

4922 "-mno-688[58]1" options.
4924 * tc-m68k.c: Added CPU32 support.

4933 Change LIBDEPS dependence to LIBS.
4935 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
4937 * Makefile.in (install): if $(tooldir) exists, install as in
4940 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4942 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4943 .word is < -32768 or > 32767. The -J flag causes the error to be
4944 ignored. This is to catch over-sized switches generated by gcc on
4945 systems which don't support the broken .word hack.
4946 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4947 write.c (fixup_segment): check for signed .word overflow if
4948 WARN_SIGNED_OVERFLOW_WORD.
4950 * write.c (fixup_segment): fixed missing parens in expression
4951 checking for byte or word overflow.
4953 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
4954 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
4955 WARN_SIGNED_OVERFLOW_WORD.
4957 * obj-coffbfd.c (fixup_segment): fixed missing parens in
4958 expression checking for byte or word overflow.
4960 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)

4963 * obj-coffbfd.h : added stuff
4964 * tc-i386.c (tc_coff_fix2rtype): new function
4965 * tc-i386.h : new coff defines
4967 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4969 * input-scrub.c (input_scrub_push): call input_file_begin, not
4971 messages.c (as_perror): print ": " between the passed in error and
4972 the strerror, like perror does.
4974 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
4976 * Makefile.in: use gas_target instead of modifying target_cpu.
4977 From Steve Chamberlain:
4978 Makefile.in: Handle m68*-*-coff*.
4979 read.c, read.h: add mult argument to s_space
4981 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4982 Motorola and MIT syntax; gas can now assemble either type of
4984 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
4985 From Steve Chamberlain:
4986 m68kcoff.mt: for m68k COFF.
4987 obj-coffbfd.c: (fixup_mdeps) added
4988 (size_section) removed bad sanity check
4989 (fill_section) added rs_machine_dependent case
4990 (write_object_file) call fixup_mdeps
4991 (fixup_segment) set fx_subsy to 0.
4992 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4994 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4997 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4999 * Makefile.in (LIBS): Include opcode library.
5001 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
5003 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
5004 including zero are accepted, pass +0.0.

5021 tc-i960.c (md_ri_to_chars): Always output bout object file in
5022 little endian byte order (used to use endianness of host).
5024 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5026 * config/tc-m68k.c (init_table): Now const. Always include 68851
5027 data, so that "bc" is available to 68040 cache instructions.
5028 Added "tt0", "tt1", and 68ec030 variants.
5029 (md_assemble): Complain if 68000 (only) and 68881 are specified.
5030 (enum _register): Added TT0, TT1.
5031 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
5032 line number correctly in "internal error" messages. Don't print
5033 architecture-mismatch message for operand errors.
5035 From Colin Smith (colin@wrs.com):
5036 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
5037 than install_operand.

5041 * listing.c (buffer_line): rewind to the start of include
5042 files, they might be included twice.

5049 one element of a family.
5051 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
5053 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
5054 so that we can assemble hand-written libgcc code.
5056 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
5058 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5059 has already been formatted (but may still contain %-characters).
5062 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5064 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5065 written with indirection on the last two operands, which can be
5066 either data or address registers. Added a new operand type 'r'
5067 which accepts either register type. Added '(' to notend stuff in
5068 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
5070 Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com)
5072 * as.h (enum _relax_state): Start off at one, not zero, to better

5081 data_last_frag): No longer static.
5082 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
5083 defined, call it. Change segments before calling fixup_segment.
5084 (relax_align): If linkrelax, provide extra padding.
5086 * obj-bout.c (obj_emit_relocations): Emit alignment relocs despite
5087 their not having symbols associated.
5089 * tc-i960.c (norelax, instrument_branches): Default initializer is
5091 (linkrelax): Delete variable definition.

5112 Mon Aug 17 15:09:56 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5114 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
5115 being used with args swapped, causing occasional lossage when
5116 refilling buffers after an include file.
5118 Mon Aug 17 13:18:51 1992 Ken Raeburn (raeburn@cygnus.com)
5120 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
5121 version. Discard bogus DONTDEF version.
5122 (as_warn, as_bad, as_fatal): Likewise.
5124 Fri Aug 14 18:31:14 1992 Ken Raeburn (raeburn@cygnus.com)
5126 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
5127 selected architecture, print a message saying so and listing what
5128 processors support it, rather than saying "operands mismatch".
5130 Thu Aug 13 13:53:19 1992 Ken Raeburn (raeburn@cygnus.com)
5132 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.

5145 if TN_SUN3; otherwise align to 2**N-byte bounary.
5147 Thu Aug 6 12:10:39 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5149 * read.c (s_fill): make the .fill size clamped error a warn and
5150 fix bug where 0's were always placed.
5152 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
5153 two bytes of any constant with 0xff:
5155 Wed Aug 5 12:02:40 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5157 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
5158 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

5168 fx_offset into account.
5170 Fri Jul 31 21:53:28 1992 Ken Raeburn (raeburn@cygnus.com)
5172 * configure.in (mips host): Accept "ultrix" with version number.
5174 * expr.c (floating_constant): Separate "=-" to avoid confusing
5175 ancient or broken compilers.
5177 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5178 processor/opcode mismatch, so reword the error message.
5179 (md_assemble): If no CPU has been set (even if FPU/PMMU
5180 characteristics have been), default to 68020. Don't need extra
5181 quotes around error string.
5183 Fri Jul 31 12:26:34 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
5185 * read.c (potable): Revert sac's incorrect change made Jul 13.
5186 Align really is supposed to be ptwo not nbytes.

5265 * write.c (write_object_file): keep the fix_tail clean, which
5266 fixes a bug in -R where relocations were being lost.

5317 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5319 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5320 where gcc looks for it.
5322 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5324 * Makefile.in: Changed some lines to be less confusing for some

5390 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5392 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5394 * expr.c (operand): if can't work out what sort of operand it is,

5397 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5399 * Makefile.in, configure.in: removed traces of namesubdir,

5401 copyrights to '92, changed some from Cygnus to FSF.
5403 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5404 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5405 copyrights to '92, changed some from Cygnus to FSF.
5407 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5409 * expr.c: If an expression is single comma, then return with
5410 SEG_ABSENT rather than an error - since the sparc front end does
5411 really strange things with things like fbge,a
5413 * as.h: include bfd.h if using many sections
5414 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5415 local labels didn't work.
5416 * listing.c (list_symbol_table): don't core dump when there's no
5418 * write.c, write.h: call fix_new with the right number of args on
5420 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5423 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5425 * app.c: MRI compatibility - allow single quote to start a string.
5426 * as.c: fix typo recently introduced.
5427 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5428 * expr.c: Much rewriting, to accomodate MRI syntax for
5429 expressions. Also easier to read now.
5430 * listing.c: Put back defuns
5431 * read.c: modified to accept MRI syntax, put back listing pseudo
5432 ops so that an assembler built with NO_LISTING ignores list ops
5434 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5435 machine is a SPARC or a 29K.
5436 * config/obj-aout.c: added s_sect pseudo op
5437 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5438 fill in the timestamp.
5439 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5440 anymore, define all the relocs which the tc-<x> bit will use so we
5441 can translate from them to the coff types.
5442 * config/tc-a29k.c: reloc_type isn't ane enum any more
5443 * config/tc-m68k.c: Added NO_RELOC definition.
5445 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5447 * Makefile.in: put header files before C source for TAGS; remove
5448 references to non-existent syscalls.h.
5450 * read.c, write.c subsegs.c: back out the .bss changes.
5452 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5454 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5458 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5460 * symbols.c (local_label_name): symbols now start with ^A.
5462 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5463 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5464 generate these sections. .align: will use NOP_OPCODE or 0
5465 for padding. This is just for being nice to the
5468 * expr.c (operand): changed to generate local label "\001L0"
5469 starting with a ^A so that it is recognized as a local label.
5471 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5473 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5474 i/o opcodes - inb, inw, outb and outw. string manipulation with
5475 att syntax - scmp, slod, smov, ssca, ssto.
5477 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5478 to just after .file .
5480 In obj_crawl_symbol_chain() where it tries to put the external
5481 symbols apart, with the condition:
5482 (!S_IS_DEFINED(symbolP) &&
5483 !S_IS_DEBUG(symbolP) &&
5484 !SF_GET_STATICS(symbolP))
5485 it was moving too many symbols out. So I switch it back to the
5487 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5489 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5490 so that we don't use the F_RELFLG which make the linker complain
5491 that somebody has stripped the relocation info.
5493 Also, the AIX ld program require that the relocation table
5494 is sorted by r_vaddr like the standard ATT assembler does.
5496 [he also changed the sizeof(struct ...)'s into the coff
5497 style FOOSZ macros. I'm not sure this is right, but I can't
5498 remember why. xoxorich.]
5500 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5502 * Makefile.in, configure.in, doc: use the doc. Build it, install
5505 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5507 * read.c: white space and comments only.
5509 * configure.in: use the new atof-ns32.c for ns32k.
5511 * write.c: comment change only.
5513 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5514 aren't yet integrated.
5516 * tc-i860.[hc]: blew off the dust. Something must still be done
5517 about conflicting relocation types.
5519 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5522 * tc-i960.c, tc-sparc.c: white space and comments only.
5524 * tc-a29k.h: delete duplicate macro definition.
5526 * new file atof-ns32k.c copied from hack's last unreleased gas.
5528 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5530 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5533 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5534 ChangeLog's prior to this are sketchy at best. I have logs.
5535 They just aren't ChangeLogs.
