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

953 * doc/as.texinfo: First pass at using new texinfo features --
954 variables, conditional tests. Far from complete.

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

1045 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.

1047 to see a segment offset here.
1049 * app.c (do_scrub_next_char): Added new state, 10, modifying state
1050 9 to only keep a space in between identifier characters.
1052 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
1054 * Makefile.in: add dvi target; as-$(config).texinfo might live in

1081 lines; I don't think that can be done portably.
1082 * config/tc-mips.c (macro): Use $AT if target register is zero in
1083 load instruction, which it can be for a floating point load.
1087 * write.c (write_contents): Compute the relocs before writing out
1088 the section contents.
1089 * config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get

1157 prototypes for all static functions. Moved existing minimal
1158 debugging format support info #ifndef OBJ_ECOFF blocks.

1209 * read.c (s_ignore): Don't declare is_end_of_line. It's
1210 redundant, and triggers a VMS gcc compiler bug.
1212 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
1213 current segment as an argument. (Ignored in all cases but VMS.)
1214 All callers and definitions changed.

1223 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,

1234 Call elf_xstabs for .stabs and .xstabs operators.
1236 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
1238 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
1241 * configure.in: mips-bsd configuration was missing format spec.
1244 * Makefile.in (Makefile): Depends on configure.in.
1246 * config/tc-mips.c (append_insn): Don't check for alignment of
1247 frag in memory; alignment of instructions in section is a separate

1365 not SEG_UNKNOWN. Use S_SET_TYPE, S_GET_TYPE, S_GET_DESC instead
1366 of referencing fields directly.
1368 * write.c (cvt_frag_to_fill): New function; extracted from
1370 (write_object_file) [! BFD_ASSEMBLER]: Call it.

1517 * configure.in: recognise all sparclite variants
1521 * read.c (s_data) [!BFD_ASSEMBLER]: Fix typo in 4 Jan change --
1522 accidentally changed to use subseg_change where it should have
1527 * expr.c (operand): If character other than comma or newline is a
1528 logical end-of-line character, use the newline case.
1529 From Eric Youngdale:
1530 (operand): Set X_add_number field for floating-point numbers.
1531 (operand): Treat zero byte as end-of-operand.
1533 * configure.in (per-target): Look for with_bfd_assembler option.
1534 For now, only accept "no", until the merge is done.
1537 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
1538 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.

1547 (which will be declared in obj-vms.h).
1548 * write.c: Add "const" modifier to md_[long,short]_jump_size.
1549 Fix arguments to VMS_write_object_file.
1550 * config-gas.com: New file. Script for VMS systems to set up the

1559 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
1560 types of malformed stabs. Change parsing algorithm so that we are
1561 more certain of having all of the information that we need on hand.
1562 * obj-vms.c (final_forward_reference): New function, used to help
1563 resolve the data types of as many struct elements as possible
1564 when some part of the struct is not fully defined by the compiler.
1565 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
1567 * obj-vms.c (VMS_write_object_file): Define all vtable psects
1568 as symbols as well in the object file. Look for external functions

1570 g++ compiler is incapable of doing this.
1571 * tc-vax.c: Add '1' option for backward compatibility with older GCC
1573 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
1574 * input-scrub.c (as_where): Fix bug where as would crash if we did not
1575 have the name of the source file yet.
1576 * config/ho-vms.h: define HO_VMS, not HO_VAX.
1580 * read.c (s_data): Always use "data_section", since it'll map to

1612 if these are used or defined, if BFD_ASSEMBLER.
1613 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old

1615 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
1617 * as.h (volatile): Don't define if already defined.
1618 (had_errors, had_warnings): Provide prototypes for ANSI C even if
1620 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
1621 declare with format attribute for -Wformat checking.
1625 * app.c, config/tc-*.c: Don't include read.h, since it is already
1628 * These are based on patches from Minh Tran-le
1630 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
1631 obj_format coffbfd and gas_target i386coff for target.

1644 * symbols.c, symbols.h (local_bss_counter): Removed.
1645 * write.c (write_object_file): bss no longer uses
1646 local_bss_counter. Pass correct data and bss size to
1647 VMS_write_object_file.
1648 * config/obj-vms.c (VMS_write_object_file): Accept bss size as
1649 argument, rather than using local_bss_counter.

1653 (size_section): Restored sanity check.
1654 (do_relocs_for): Base section address on s_paddr rather than
1655 computing it. Adjust a29k R_IHIHALF special case to account for
1656 section paddr (used to require paddr to be zero). If there are no
1657 reclos, set s_relptr to 0. Set relocation size in object_headers.
1658 (fill_section): Always set s_vaddr here, removing
1659 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

1661 Set STYP_INFO for .comment.
1662 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
1663 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

1667 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
1668 set s_vaddr here. If string_byte_count remains 4, set it back to
1669 0, and only write strings out if there are some. Call
1670 fill_section before do_relocs_for and do_linenos_for.
1671 (obj_coff_section): Handle optional quoted second argument giving
1672 section characteristics.
1673 (obj_coff_bss): Added to handle .bss.
1674 (obj_coff_ident): Added to handle .ident (puts string in .comment

1700 * config/obj-coff.h: Don't use #elif.
1702 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
1707 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is
1712 * app.c (do_scrub_begin): allow single quote strings if so
1715 * config/*z8k*: checkpoint
1719 * read.c (read_a_source_file): avoid calling xmalloc (0).
1723 * listing.c: Call xmalloc, not malloc; don't declare malloc.
1725 * Changes to support SCO 3.2v4:

1729 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
1730 using ZERO_BASED_SEGMENTS.
1731 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
1732 never set segment address for SEG_E2 (.bss) and don't write out
1733 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
1734 (obj_coff_endef): Don't merge labels or symbols awaiting forward
1735 definitions, and don't merge tags with non-tags. Check for .bf
1736 rather than just checking whether the second character is b and
1737 the third character is f.
1738 (obj_coff_val): gcc can generate values which we don't handle
1739 correctly; discard information for now, since it only affects the
1740 debugging information.
1741 (tag_find_or_name): Don't insert tags in the symbol table.
1742 (yank_symbols): Don't merge labels.
1743 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

1745 set segment address if ZERO_BASED_SEGMENTS.
1746 (obj_coff_section): Accept and ignore a trailing quoted string, as
1747 used in AT&T i386 syntax.

1886 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
1888 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;

1947 so widening works consistently.
1951 * version.c: Put conditional "const" before version_string, not
1952 before dummy function for VMS. Now version 1.91.03.
1954 * app.c (do_scrub_next_char): Need double-\ before `000' to show
1955 printed rep of null character.
1959 * obj-coffbfd.c (write_object_file): check return value of
1964 * Support for i386-sysv.
1965 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

1984 fix i960+non-bfd coff bit rot.
1985 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
1986 support for C source listings. (obj_coff_endef): look in the right
1987 part of the symbol for the symbol name
1989 * tc-m68k.c (get_num): make it work for all segments, not just the
1992 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)
1994 * configure.in: recognize i386-*-bsd emulation.
1996 Thu Oct 1 23:05:12 1992 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
1998 * configure.in: use the cpu-vendor-os triple for host and target
2002 * obj-coffbfd.c (write_object_file): don't fixup for the z8k
2003 * tc-z8k.c: lots of bug fixes
2007 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
2008 #elif, since it is not supported by old compilers.
2009 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
2010 couple of expressions in tc-m68k.c.
2014 * read.c (cons): If NO_RELOC is defined, use it.
2016 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
2020 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
2021 local labels to start with a .) and set REGISTER_PREFIX to %.
2022 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
2026 * messages.c: Comment changes.
2030 * as.h: Test if __STDC__ is defined only, don't test its value.
2031 * messages.c: If __STDC__ is not defined, define NO_STDARG.
2035 * listing.c (debugging_pseudo): Add stabs and stabn as things to
2040 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
2041 sections starting from zero, rather than making them consecutive.
2042 This makes subsequent reloc calculations easier, esp if the object
2043 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
2044 allocate lcomm in .data rather than in .bss. It seems that some
2045 tools can't cope with a non-zero sized bss before linkage.
2049 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
2050 throughout. That enum no longer means what we thought it meant.

2053 "-mno-688[58]1" options.
2055 * tc-m68k.c: Added CPU32 support.

2073 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
2074 .word is < -32768 or > 32767. The -J flag causes the error to be
2075 ignored. This is to catch over-sized switches generated by gcc on
2076 systems which don't support the broken .word hack.
2077 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
2078 write.c (fixup_segment): check for signed .word overflow if
2079 WARN_SIGNED_OVERFLOW_WORD.
2081 * write.c (fixup_segment): fixed missing parens in expression
2082 checking for byte or word overflow.
2084 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
2085 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
2086 WARN_SIGNED_OVERFLOW_WORD.
2088 * obj-coffbfd.c (fixup_segment): fixed missing parens in
2089 expression checking for byte or word overflow.

2096 * tc-i386.h : new coff defines
2100 * input-scrub.c (input_scrub_push): call input_file_begin, not
2102 messages.c (as_perror): print ": " between the passed in error and
2103 the strerror, like perror does.
2107 * Makefile.in: use gas_target instead of modifying target_cpu.
2108 From Steve Chamberlain:
2109 Makefile.in: Handle m68*-*-coff*.

2112 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
2113 Motorola and MIT syntax; gas can now assemble either type of
2115 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
2116 From Steve Chamberlain:
2117 m68kcoff.mt: for m68k COFF.
2118 obj-coffbfd.c: (fixup_mdeps) added
2119 (size_section) removed bad sanity check
2120 (fill_section) added rs_machine_dependent case
2121 (write_object_file) call fixup_mdeps
2122 (fixup_segment) set fx_subsy to 0.
2123 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
2125 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala

2134 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
2135 including zero are accepted, pass +0.0.
2139 * Makefile.in: map "as" through program_transform_name when
2142 * doc/Makefile.in: map "as" through program_transform_name when
2147 * Makefile.in (as.new): Depend on LOCAL_LOADLIBES.
2151 * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars),
2152 tc-i960.c (md_ri_to_chars): Always output bout object file in
2153 little endian byte order (used to use endianness of host).
2157 * config/tc-m68k.c (init_table): Now const. Always include 68851
2158 data, so that "bc" is available to 68040 cache instructions.

2167 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
2168 than install_operand.
2172 * listing.c (buffer_line): rewind to the start of include
2173 files, they might be included twice.
2175 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
2179 * Makefile.in: defined TARGET_CPU for C code so that it can choose
2180 one element of a family.
2182 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
2184 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
2185 so that we can assemble hand-written libgcc code.
2189 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
2190 has already been formatted (but may still contain %-characters).
2195 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
2196 written with indirection on the last two operands, which can be
2197 either data or address registers. Added a new operand type 'r'
2198 which accepts either register type. Added '(' to notend stuff in
2199 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.
2203 * as.h (enum _relax_state): Start off at one, not zero, to better
2204 catch uninitialized-variable errors.
2205 (linkrelax): Declare new variable.
2207 * messages.c (warning_count, error_count): Default initializer is
2210 * write.c: Merged some declarations, using PARMS macro.
2211 (text_frag_root, data_frag_root, bss_frag_root, text_last_frag,
2212 data_last_frag): No longer static.
2213 (write_object_file, case rs_align or rs_org): If HANDLE_ALIGN is
2214 defined, call it. Change segments before calling fixup_segment.

2225 (i960_handle_align): New function.
2226 * tc-i960.h (linkrelax): Delete declaration.

2239 FLAGS_TO_PASS to recursive makes.
2241 * doc/Makefile.in: always create installation directories.
2245 * input-scrub.c (input_scrub_pop, input_scrub_push): memcpy was
2246 being used with args swapped, causing occasional lossage when
2247 refilling buffers after an include file.
2251 * messages.c (as_tsktsk): Use correct ANSI form for stdarg
2252 version. Discard bogus DONTDEF version.
2253 (as_warn, as_bad, as_fatal): Likewise.
2257 * config/tc-m68k.c (m68k_ip): If instruction is invalid for the
2258 selected architecture, print a message saying so and listing what
2259 processors support it, rather than saying "operands mismatch".
2263 * as.h [BROKEN_ASSERT]: If defined, turn off all assertion checks.
2265 * config/ho-rs6000.h (M_RS6000): Don't define it.
2267 (BROKEN_ASSERT): Define it if not __STDC__.
2271 * sparc.mt: New file.
2275 * tc-m68k.c: ".align N" means align to N-byte boundary *only*
2276 if TN_SUN3; otherwise align to 2**N-byte bounary.
2280 * read.c (s_fill): make the .fill size clamped error a warn and
2281 fix bug where 0's were always placed.
2283 * config/tc-h8300.c: if a :8 is seen after an operand, fill top
2284 two bytes of any constant with 0xff:
2288 * config/tc-m68k.c (md_pseudo_table): fix the .align thing
2289 the right way; for just the 68k. Sun 3 .align is nbytes, not ptwo.

2305 * expr.c (floating_constant): Separate "=-" to avoid confusing
2306 ancient or broken compilers.
2308 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
2309 processor/opcode mismatch, so reword the error message.
2310 (md_assemble): If no CPU has been set (even if FPU/PMMU
2311 characteristics have been), default to 68020. Don't need extra
2312 quotes around error string.
2316 * read.c (potable): Revert sac's incorrect change made Jul 13.
2317 Align really is supposed to be ptwo not nbytes.

2381 * expr.c(expr): allow SEG_REGISTER in expressions.
2382 * read.c(pseudo_set): register expressions can be the source of a

2388 * config/obj-a.out (s_sect): complain if the user tries to use a
2389 subsegment with a value which might interfere with out -R hackery.
2390 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
2391 rather than use ugly if tree. (init_regtable): insert register
2392 names into symbol table.
2396 * write.c (write_object_file): keep the fix_tail clean, which
2397 fixes a bug in -R where relocations were being lost.
2401 * configure.in: recognize m680x0 as having sun3 emulation mode for
2402 vxworks environment.
2406 * configure.in: recognize m680x0 as an m68k
2410 * configure.in: Recognize sparclite as a sparc variant.
2412 * tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new
2417 * config/tc-a29k.c: lint
2418 * listing.c, expr.c: patches from Andrew Smith
2422 * doc/Makefile.in: use m4 rather than gm4.

2437 * Makefile.in: do not print recursion lines.
2441 * Makefile.in: the tooldir copy of gas goes directly in tooldir.
2445 * write.c (write_object_file): For b.out format, round up section
2446 start addresses to match required alignment.
2450 * Makefile.in (install): Install into $(tooldir)/bin, since that's
2451 where gcc looks for it.
2455 * Makefile.in: Changed some lines to be less confusing for some
2458 * input-file.c: Conditionalize on _IOFBF, not VMS.
2460 * read.c, write.c: Change a series of ifdef/elif to
2461 ifdef/else/ifdef etc.
2465 * symbols.c (fb_label_init): fix sizeof to memset.
2469 * Makefile.in: install the man page.
2471 * Makefile.in: pass down MAKEINFO explicitly on info.
2473 * doc/Makefile.in: use $(MAKEINFO) not makeinfo.
2477 * flonum-const.c: renamed flonum-konst.c to stop dos name
2482 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
2483 tc-m68k.h to te-sun3.h.
2487 * configure.in: vxworks68 gets te-sun3.h.
2489 * expr.c: remove limitation that local_labels_dollar or
2490 local_labels_fb must be < 10.
2492 * symbols.c: remove local_labels_dollar, replace with a function
2493 interface for a sparse array. All users adjusted.
2495 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
2499 * doc/Makefile.in: commented out line for building as-all.texinfo.
2502 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
2506 * Makefile.in: added check target.
2510 * Makefile.in: added tooldir and program_prefix.
2514 * write.{c,h} (fix_new): Make these declarations consistent.
2518 * Makefile.in (strerror.o): Add rule so that broken Sun make can
2521 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
2523 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
2525 * expr.c (operand): if can't work out what sort of operand it is,
2526 then look through FLT_CHARS for a hint.
2530 * Makefile.in, configure.in: removed traces of namesubdir,
2531 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2532 copyrights to '92, changed some from Cygnus to FSF.
2534 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
2535 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2536 copyrights to '92, changed some from Cygnus to FSF.
2538 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2540 * expr.c: If an expression is single comma, then return with
2541 SEG_ABSENT rather than an error - since the sparc front end does
2542 really strange things with things like fbge,a
2544 * as.h: include bfd.h if using many sections
2545 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
2546 local labels didn't work.
2547 * listing.c (list_symbol_table): don't core dump when there's no
2549 * write.c, write.h: call fix_new with the right number of args on
2551 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
2554 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2556 * app.c: MRI compatibility - allow single quote to start a string.
2557 * as.c: fix typo recently introduced.
2558 * as.h : Don't include aout/reloc.h - it's not right for COFF!
2559 * expr.c: Much rewriting, to accomodate MRI syntax for
2560 expressions. Also easier to read now.
2561 * listing.c: Put back defuns
2562 * read.c: modified to accept MRI syntax, put back listing pseudo
2563 ops so that an assembler built with NO_LISTING ignores list ops
2565 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
2566 machine is a SPARC or a 29K.
2567 * config/obj-aout.c: added s_sect pseudo op
2568 * config/obj-coffbfd.c: lints, set the filehdr flags right and
2569 fill in the timestamp.
2570 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
2571 anymore, define all the relocs which the tc-<x> bit will use so we
2572 can translate from them to the coff types.
2573 * config/tc-a29k.c: reloc_type isn't ane enum any more
2574 * config/tc-m68k.c: Added NO_RELOC definition.
2578 * Makefile.in: put header files before C source for TAGS; remove
2579 references to non-existent syscalls.h.
2581 * read.c, write.c subsegs.c: back out the .bss changes.
2583 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
2585 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
2591 * symbols.c (local_label_name): symbols now start with ^A.
2593 * read.c, subsegs.c, write.c obj-coff.c: added handling of
2594 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
2595 generate these sections. .align: will use NOP_OPCODE or 0
2596 for padding. This is just for being nice to the
2599 * expr.c (operand): changed to generate local label "\001L0"
2600 starting with a ^A so that it is recognized as a local label.
2602 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
2604 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
2605 i/o opcodes - inb, inw, outb and outw. string manipulation with
2606 att syntax - scmp, slod, smov, ssca, ssto.
2608 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
2609 to just after .file .
2611 In obj_crawl_symbol_chain() where it tries to put the external
2612 symbols apart, with the condition:
2613 (!S_IS_DEFINED(symbolP) &&
2614 !S_IS_DEBUG(symbolP) &&
2615 !SF_GET_STATICS(symbolP))
2616 it was moving too many symbols out. So I switch it back to the
2618 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
2620 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
2621 so that we don't use the F_RELFLG which make the linker complain
2622 that somebody has stripped the relocation info.
2624 Also, the AIX ld program require that the relocation table
2625 is sorted by r_vaddr like the standard ATT assembler does.
2627 [he also changed the sizeof(struct ...)'s into the coff
2628 style FOOSZ macros. I'm not sure this is right, but I can't
2629 remember why. xoxorich.]
2633 * Makefile.in, configure.in, doc: use the doc. Build it, install
2636 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
2638 * read.c: white space and comments only.
2640 * configure.in: use the new atof-ns32.c for ns32k.
2642 * write.c: comment change only.
2644 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
2645 aren't yet integrated.
2647 * tc-i860.[hc]: blew off the dust. Something must still be done
2648 about conflicting relocation types.
2650 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
2653 * tc-i960.c, tc-sparc.c: white space and comments only.
2655 * tc-a29k.h: delete duplicate macro definition.
2657 * new file atof-ns32k.c copied from hack's last unreleased gas.
2659 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
2661 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
2664 * nearly everything. flush ChangeLog, package as gas-1.92.1.
2665 ChangeLog's prior to this are sketchy at best. I have logs.
2666 They just aren't ChangeLogs.
