1 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
3 * config/tc-mips.c: Include subsegs.h.
4 (md_apply_fix): If an unconditional b or bal overflows, and we are
5 not assembling PIC code, replace it with a j or jal.
7 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
8 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
10 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
12 * write.c (write_relocs): Add file name and line number to
13 as_fatal calls. Handle bfd_reloc_overflow case specifically when
14 RELOC_EXPANSION_POSSIBLE.

22 [!USE_STDARG && !USE_VARARGS] (va_alist, va_dcl, ...): Provide
23 default definitions matching what we were doing before.
24 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
25 always use the varargs form if not using stdarg. It's safe to
26 always use vfprintf, because libiberty will provide it if the
27 native system doesn't. Also, always make format be const.
28 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
30 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
32 * config/tc-mips.c (load_register): Always use addiu when adding a
33 constant to $zero--no need to use daddiu.
34 (macro): Hack the -mips3 overflow tests to not fail when offsetT
37 * symbols.h (copy_symbol_attributes): Declare.
39 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
41 * listing.c: Bugfixes based in part on patches from Paul
43 (listing_newline): Check filename as well as line number when
44 deciding whether to record it.
45 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
46 false (if defined) as well as checking for reg_section.
47 (listing_listing): Iterate fetching lines while line number is too
48 low, and we haven't run off the end of the input file.
50 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
52 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

75 md_estimate_size_before_relax, md_ri_to_chars,
76 md_create_short_jump, md_create_long_jump.
77 (brtab_emit): Use data_section, not SEG_DATA.
79 Mon Sep 19 17:14:44 1994 Pat Rankin (rankin@eql.caltech.edu)
81 * config/vms-conf.h: new file, manually derived from conf.in.
82 * config-gas.com: use it, and eliminate obsolete "host.h".
84 Wed Sep 21 11:11:30 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
86 * config/tc-ppc.c (ppc_current_block): New static variable.
87 (ppc_stabx): Set sy_tc.within of a C_STSYM symbol to

91 (ppc_es): Clear ppc_current_block.
92 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
93 from the csect of the enclosing block.
95 * config/tc-mips.c (insns_since_cache_access): Remove.
96 (append_insn): Remove setting of insns_since_cache_access, and
97 special 4600 handling; it turns out not to be required.
99 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
101 * config/tc-mips.c (md_shortopts): Remove E.
102 (md_longopts): Add EB and EL.
103 (md_parse_option): Handle -EB and -EL as separate options, rather
104 than as a single -E option with an argument.
106 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
108 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
109 involving global symbols too.
111 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
113 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
115 * configure.in: Test for remove, not delete. Fix cross-assembler
117 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
120 * read.c (pseudo_set, case O_symbol): If
121 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
122 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.
123 * config/obj-elf.h (OBJ_COPY_SYMBOL_ATTRIBUTES): Define.
125 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
127 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
128 many others): new macros; values obtained from "DSTRECRDS.SDL".
129 * config/obj-vms.h (various): use them.
130 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
131 representation (only enum bitfields can avoid being bitstrings).
132 (bitfield_suffix, setup_basic_type): new routines.
133 (VMS_typedef_parse): use them. Now recognize bitfields of all
134 integral types, not just type `int'. Caveat: the representation
135 used for bitfields still does not work for objects placed in
136 registers, and gcc's optimizer sometimes puts small structs there.
138 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
140 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
142 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
143 (tc_frob_label): define this to call vms_check_for_special_label,
144 and declare the latter.
145 * config/obj-vms.c (vax_g_doubles): declare this file-scope
147 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
148 (vms_check_for_special_label): new routine (tc_frob_label).
149 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
150 and `gcc2_compiled.' labels; they won't reach here any more.
151 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
152 double', use `vax_g_doubles' flag to select type of double.
153 (VMS_write_object_file) [traceback setup]: don't pass symbols
154 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
155 and TBT_Routine_End functions.
157 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
159 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
160 S_GET_VALUE() to avoid many repeated function calls.
161 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
162 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
163 gets requested. [All the HACK_DEC_C_STARTUP code appears to
164 be obsolete; gcc does it automatically for vms target. It's
165 also misnamed, because it is for the "VAX C" run-time library,
166 not the newer "DEC C" one which has much different startup code.]
167 {various}: use `S_SET_xxx(symbol,new_value)' rather than
168 `S_GET_xxx(symbol) = new_value'.

172 * config/obj-coff.c (c_dot_file_symbol): Use bfd_abs_section_ptr,

177 * expr.c (clean_up_expression): Use addressT, not bfd_vma.
179 Tue Sep 13 20:05:47 1994 Jeff Law (law@snake.cs.utah.edu)
181 * expr.c (expr): Don't reduce the difference of two symbols in the
182 same frag if the symbols are not in normal sections.
184 * config/obj-som.h (S_SET_OTHER, S_SET_TYPE): Delete a.out crud.
185 (S_SET_DESC, S_GET_OTHER, S_GET_TYPE, S_GET_DESC): Likewise.
186 (obj_attach_unwind_info): Do not define. Not needed anymore.
187 * config/tc-hppa.c: Delete whitespace at EOL.
188 (struct hppa_fix_struct): Delete fx_unwind field and all references.
189 (fix_new_hppa): Last arg is now a pointer to an int. Do not
190 call obj_attach_unwind_info anymore. For SOM R_ENTRY and R_EXIT
191 fixups, store 32bits of unwind information in the fx_addnumber
193 (md_assemble, pa_entry, process_exit, pa_procend): For SOM R_ENTRY
194 and R_EXIT fixups, pass a NULL pointer to fix_new_hppa, and a
195 pointer to 32 bits of unwind info.
196 (tc_gen_reloc): For SOM R_ENTRY and R_EXIT fixups, set the symbol
197 pointer to the dummy symbol; set the addend field to fx_addnumber.
198 (pa_comm, pa_equ, pa_type_args, pa_import): Use bfd_XXX_section_ptr
199 rather than &bfd_XXX_section.
201 Tue Sep 13 21:15:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
203 * config/tc-i386.c (md_apply_fix_1): For GOTPC relocs, decrement
204 value by one; discard adjustments previously being made. From
207 VMS- and Vax-related changes from Pat Rankin:
208 * Makefile.in (VMS_OTHER_OBJS): add concat, getopt, and getopt1.
209 * vmsconf.sh: no longer have make-gas.com echo text about needing
210 to modify the gcc-vms driver when intending to use with gcc 1.x.
211 * as.c (parse_options): suppress 'v' from std_short_options and
212 eliminate VMS-specific conditional initialization;
213 [default case]: check for '-v' if md_parse_options doesn't recognize
215 [default case, #if VMS]: check for filename argument when '-v' seen;
217 * config/tc-vax.c (md_assemble): don't rely on `this_add_number'
218 for O_big literal operands (double floats and long long ints);
219 [VMS, md_shortopts]: add second colon after 'v';
220 (md_parse_options) [VMS, case 'v']: check for argument, so
221 caller can handle `-v' w/o arg.

273 * gdbinit.in: New file, created from old .gdbinit.
275 * aclocal.m4 (GAS_GDBINIT): Deleted.
276 * configure.in: Don't use it. Instead, generate .gdbinit from
277 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
278 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
279 to ensure that older versions of autoconf aren't used.
280 * Makefile.in: Added @configure_input@ line.

371 * read.c (read_a_source_file): The second argument to as_where is
372 unsigned int *, not int *.

419 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
420 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
421 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
422 message to try to ease confusion about autoconf's
423 "cross-compiling" message.
424 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
425 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

1561 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
1562 also before setting STYP_NOLOAD for .bss section.

1638 * config/tc-mips.c (append_insn): Permit branches to be switched
1639 with the preceding instruction even if .set nobopt has been seen.
1640 .set nobopt actually controls whether to bring up an instruction
1641 from the branch target, which gas does not currently support.

1781 elf_tc_make_sections stuff. It was there to support PA braindamage
1782 which has been fixed, and in the case of elf_tc_make_sections is
1783 redundant with elf_tc_final_processing.

1916 (macro): Handle EMBEDDED_PIC in all PIC cases.
1917 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1918 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1919 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1920 works). Do not permit -G with SVR4_PIC.
1921 (s_abicalls): Warn if -G was used, and force -G 0.
1922 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for

1928 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1930 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1931 parameters to avoid losing when compiling with HP CC.

1934 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1936 * Makefile.in (config-stamp): If `defs' is defined, emit a
1937 preprocessor directive to create a macro named by this value into
1938 config.new; don't explicitly go for BFD_ASSEMBLER.
1939 * configure.in: Define `defs', not `BFDDEF'. Set it to
1940 MANY_SEGMENTS for any obj-coffbfd target.
1941 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1942 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,

1975 (adjust_reloc_syms): For now, always supply an absolute symbol for
1976 fixups without symbols but not yet `done'. Use section_symbol to
1977 get the symbol, instead of going directly for abs_symbol.
1978 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
1979 reloc is not a section symbol and is not in the symbol table.
1980 (set_symtab): New function, broken out from write_object_file.
1981 Counts symbol table instead of relying on an earlier count.
1982 (write_object_file): Call set_symtab, but do it after potentially
1983 invoking the *_frob_file macros. Don't bother counting symbols.
1984 Call symbol_remove, instead of expanding it in place. Moved the
1985 conditionalized `object_file_size' declaration down to
1986 conditionalized block where it's used. When using the absolute
1987 symbol for a fixup without a symbol, set sy_used_in_reloc.
1988 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
1989 the correct symbol for the absolute section.
1991 * subsegs.c (section_symbol): Use symbol_new instead of
1992 symbol_make, since we may want it to go into the symbol table.
1993 Make the new symbol have internal linkage. If
1994 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
1995 symbol with the newly created GAS symbol.
1996 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
1997 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2004 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2005 (sparc_ip, label "immediate"): Reject constants for pcrel
2006 instructions only if the relocation type indicates a "call"
2007 instruction and the offset is within range of a "jmpl %g0". If
2008 it's not in range, use the absolute section symbol plus an offset.
2009 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2011 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2013 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2016 * configure.in: Eliminated all targets using obj-coff but not
2017 defining BFD_ASSEMBLER; I think all such targets that are
2018 supported will be matched by real CPU-OS combinations earlier in
2020 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2021 some comments about the dpx2 configuration, but left it disabled,
2022 since it couldn't be reached before.
2023 (target a29k-amd-ebmonold): Deleted.

2033 the 'j' operand if there are no further alternatives for this
2036 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2037 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2038 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2040 * config/tc-mips.c (mips_align): Take new argument, label, and use
2041 it instead of global insn_label.
2042 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2043 call to mips_emit_delay and pass it to mips_align.
2045 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2047 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.

2065 values to reduce number of lookups with S_GET_VALUE. Skip debug
2066 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2067 holger@botbso.rhein-main.de.)
2068 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2069 field. (Also from Holger Teutsch.) Watch for a would-be register
2070 mask that spans frags.
2072 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2073 this_base, not line_base. (Patch from Andreas Arens,

2077 look local if they're exported or undefined. Used to be done for
2080 * read.c (s_lcomm, s_comm): Print symbol name being redefined.

2084 (lex_type): Use it for `%'.
2086 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

4212 still being worked on. Mark Elf configurations (except sparc and
4213 i386) as developmental. Deleted cases matching some generic names
4214 in favor of more specific names. (E.g., when we get Alpha
4215 support, we'll still only support VMS for Vax.)
4217 * config/tc-sparc.h (md_end): New macro.
4218 * config/tc-sparc.c (md_end): Function deleted.
4219 (BFD_RELOC_*): Delete macros that used to help keep the non-bfd

4229 against placing additional object-file dependent code here. Warn
4230 against contaminating all of GAS with the internals of tc-hppa.c
4231 through inclusion of tc-hppa.h. Delete all forward declarations
4232 for functions only used within tc-hppa.c, likewise for structures,
4233 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4234 conditional code in a few small places.
4236 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4237 structures, global variables, forward declarations together.
4238 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
4239 conditional code -- try to group conditional code together
4240 into a few places. Make all functions and variables which
4241 are only used within tc-hppa.c static. PARAMize all functions.
4242 Add comments to functions. Delete unused functions, variables,
4243 #defines, etc. Delete unused members within structures. Delete
4244 ldil;ble hacks -- it is believed they were installed to work
4245 around old gas bugs. Avoid using mixed case for local
4246 functions, variables, and structures. Fix formatting problems
4247 not found by GNU-indent. Add FIXME notices for things which
4248 should be worked on the near future. Delete lots of old
4249 useless (1.36 PA-SOM) code.
4251 * config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
4252 field of the fixS structure. Needed to build unwind

4269 of elf32_symbol_type.
4270 (pa_export_args): Likewise.
4271 (elf_hppa_final_processing): Likewise.

4278 a multiple of the section alignment rather than always a
4281 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4282 bits are zero (eg they specify no relocations), then do not even
4283 bother adding their entries to thesymextn section.

4328 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4330 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4331 ELF, since the ELF object format does not have these type of
4332 relocations. Change the abort into as as_bad and return
4333 BFD_RELOC_NONE to silence compiler warnings.
4334 (md_assemble): Keep track of the instruction size. Allow white
4335 space between the $ and the constant for compatibility with older

6720 a29k .bss section; the mondfe program doesn't like it.

6741 source directory, if that's not the current directory.
6743 * configure.in (per-host): Accept MIPS host with BSD version

6765 process relocs if there aren't any relocs to process. Avoids
6766 malloc/free bug on SCO too.

6769 avoid some redefinition complaints on some systems.
6770 (const, volatile): Don't need these conditionally defined if we
6771 use CONST and VOLATILE from ansidecl.h.
6772 (seg_name): Use CONST, not const.
6774 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6776 * config/tc-mips.c: Reindented to GNU standards.
6778 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6780 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6781 (fixup_segment): Add a29k special case; the linker is not prepared
6782 to see a segment offset here.
6784 * app.c (do_scrub_next_char): Added new state, 10, modifying state
6785 9 to only keep a space in between identifier characters.
6787 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6789 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6790 srcdir, might be in objdir.
6792 * doc/Makefile.in: dvi depends on as.dvi

6810 * config/tc-m68k.c (m68k_ip): For operand type 'M', reject
6811 bignums, but don't emit error message.
6813 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
6815 * Makefile.in (targ-cpu.o): Depend on config.h.
6817 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
6819 * app.c (do_scrub_next_char): Added new state, 9, to avoid
6820 dropping a space immediately following an identifier.
6821 * expr.c, write.c: Rewrote assert expressions to not use multiple
6822 lines; I don't think that can be done portably.
6823 * config/tc-mips.c (macro): Use $AT if target register is zero in
6824 load instruction, which it can be for a floating point load.
6826 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

6837 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6838 z8k-opc.h, not z8k.h.
6840 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6843 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6894 OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.

6898 prototypes for all static functions. Moved existing minimal
6899 debugging format support info #ifndef OBJ_ECOFF blocks.

6902 all callers accordingly.
6903 (tc_get_register): Renamed from get_register, and made non-static.

6945 Wed Mar 3 10:41:46 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
6947 Patches from Eric Youngdale:
6948 * make-gas.com: Find obstack.obj if it's not in the current
6950 * read.c (s_ignore): Don't declare is_end_of_line. It's
6951 redundant, and triggers a VMS gcc compiler bug.
6953 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6954 current segment as an argument. (Ignored in all cases but VMS.)
6955 All callers and definitions changed.
6957 Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
6959 * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
6962 Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
6964 * config/tc-m68k.c (isbyte): Accept all values from -255 to +255,

6971 (obj_elf_xstab): New routine.
6972 (obj_elf_set_size): Call as_warn, not fprintf. Pass desired
6973 argument to s_ignore. Put "#if 0" around unused code.
6974 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6975 Call elf_xstabs for .stabs and .xstabs operators.
6977 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
6979 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
6982 * configure.in: mips-bsd configuration was missing format spec.
6985 * Makefile.in (Makefile): Depends on configure.in.
6987 * config/tc-mips.c (append_insn): Don't check for alignment of
6988 frag in memory; alignment of instructions in section is a separate
6991 * config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI

6997 Tue Mar 2 00:50:43 1993 John Gilmore (gnu@cygnus.com)

7008 * config/tc-sparc.c (s_xword): Now call big_cons, so large
7009 constants are accepted, but symbolic values are not. GCC will not
7010 generate the latter currently.
7012 * frags.c (frag_init): New function.
7013 (zero_address_frag, bss_address_frag): Now initialized at run

7282 * expr.c (operand): If character other than comma or newline is a
7283 logical end-of-line character, use the newline case.

7285 (operand): Set X_add_number field for floating-point numbers.
7286 (operand): Treat zero byte as end-of-operand.
7288 * configure.in (per-target): Look for with_bfd_assembler option.
7289 For now, only accept "no", until the merge is done.
7291 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):

7301 md_[long,short]_jump_size. Remove declaration of const_flag
7302 (which will be declared in obj-vms.h).
7303 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7304 Fix arguments to VMS_write_object_file.
7305 * config-gas.com: New file. Script for VMS systems to set up the

7314 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7315 types of malformed stabs. Change parsing algorithm so that we are
7316 more certain of having all of the information that we need on hand.
7317 * obj-vms.c (final_forward_reference): New function, used to help
7318 resolve the data types of as many struct elements as possible

7336 SEG_DATA or SEG_E1 if needed.
7337 (s_lcomm): Likewise with bss_section.
7338 (s_fill): Use memset, not bzero.

7367 if these are used or defined, if BFD_ASSEMBLER.
7368 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7369 subseg_new split into two functions.
7370 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7372 * as.h (volatile): Don't define if already defined.
7373 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7396 name rather than L0\001.
7397 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7399 * symbols.c, symbols.h (local_bss_counter): Removed.
7400 * write.c (write_object_file): bss no longer uses

7408 (size_section): Restored sanity check.
7409 (do_relocs_for): Base section address on s_paddr rather than
7410 computing it. Adjust a29k R_IHIHALF special case to account for

7412 reclos, set s_relptr to 0. Set relocation size in object_headers.
7413 (fill_section): Always set s_vaddr here, removing
7414 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set

7420 H_{SET,GET}_* macros.
7421 (do_linenos_for): Set lineno size in object_headers.
7422 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7423 set s_vaddr here. If string_byte_count remains 4, set it back to
7424 0, and only write strings out if there are some. Call
7425 fill_section before do_relocs_for and do_linenos_for.
7426 (obj_coff_section): Handle optional quoted second argument giving
7427 section characteristics.
7428 (obj_coff_bss): Added to handle .bss.

7455 * config/obj-coff.h: Don't use #elif.
7457 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
7458 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
7460 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)

7472 Sun Dec 13 00:04:38 1992 Ian Lance Taylor (ian@cygnus.com)
7474 * read.c (read_a_source_file): avoid calling xmalloc (0).
7476 Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com)
7478 * listing.c: Call xmalloc, not malloc; don't declare malloc.
7480 * Changes to support SCO 3.2v4:
7481 * read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
7482 SEG_BSS, fill with NOP_OPCODE.
7483 * config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
7484 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
7485 using ZERO_BASED_SEGMENTS.
7486 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
7487 never set segment address for SEG_E2 (.bss) and don't write out
7488 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
7489 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7490 definitions, and don't merge tags with non-tags. Check for .bf
7491 rather than just checking whether the second character is b and
7492 the third character is f.
7493 (obj_coff_val): gcc can generate values which we don't handle
7494 correctly; discard information for now, since it only affects the
7495 debugging information.

7497 (yank_symbols): Don't merge labels.
7498 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
7499 already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
7500 set segment address if ZERO_BASED_SEGMENTS.
7501 (obj_coff_section): Accept and ignore a trailing quoted string, as
7502 used in AT&T i386 syntax.

7504 relative addends by the segment vaddr.
7505 * tc-i386.h: Define SUB_SEGMENT_ALIGN.
7506 * tc-a29k.h: Define ZERO_BASED_SEGMENTS.
7507 * tc-i386.c: (i386_operand): If I386COFF, accept any segment type.

7608 xrealloc from xrealloc.c.
7609 * xrealloc.c: Deleted.
7610 * Makefile.in (REAL_SOURCES, OBJS): Adjusted.
7612 * configure.in: For host CPU a29k, rs6000, vax, consider using bsd
7615 * config/ho-sysv.h (setbuffer, HO_USG): Deleted.
7617 * config/atof-ieee.c (atof_ieee): Exponent field isn't a pointer;

7636 * all files: Whitespace changes for GNU indentation style, done by
7637 GNU `indent'. Some cleanup still needed, especially of comments.
7639 * configure.in: No te-386bsd.h file exists; don't try to use it.
7641 * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
7643 * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881;
7644 could be doing emulation.
7646 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7649 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7652 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)
7654 * Makefile.in (as.o, obj-format.o): added dependency on subsegs.h.

7676 consistently const, and always initialized them. Included read.h.
7678 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7680 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7681 constant will not fit in an immediate field.
7682 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
7684 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
7686 * obj-coff.c (callj_table): Delete global variable.

7704 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
7706 * version.c: Put conditional "const" before version_string, not

7717 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7719 * Support for i386-sysv.
7720 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7724 (fill_section): Don't set STYP_NOLOAD for .bss section.
7725 (fixup_segment): 386 uses strange common symbol format.

7739 fix i960+non-bfd coff bit rot.
7740 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
7741 support for C source listings. (obj_coff_endef): look in the right

7758 * tc-z8k.c: lots of bug fixes
7760 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7762 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7763 #elif, since it is not supported by old compilers.
7764 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7765 couple of expressions in tc-m68k.c.
7767 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7769 * read.c (cons): If NO_RELOC is defined, use it.
7771 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
7773 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
7775 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
7776 local labels to start with a .) and set REGISTER_PREFIX to %.
7777 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
7779 Fri Sep 25 17:53:43 1992 John Gilmore (gnu@cygnus.com)
7781 * messages.c: Comment changes.
7783 Fri Sep 25 14:12:58 1992 Ken Raeburn (raeburn@kyriath.cygnus.com)

7786 * messages.c: If __STDC__ is not defined, define NO_STDARG.
7788 Thu Sep 24 12:42:32 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
7790 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7793 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7795 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7796 sections starting from zero, rather than making them consecutive.
7797 This makes subsequent reloc calculations easier, esp if the object
7798 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7799 allocate lcomm in .data rather than in .bss. It seems that some
7800 tools can't cope with a non-zero sized bss before linkage.
7802 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7804 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
7805 throughout. That enum no longer means what we thought it meant.

7808 "-mno-688[58]1" options.
7810 * tc-m68k.c: Added CPU32 support.

7816 Tue Sep 15 17:25:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7818 * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.
7819 Change LIBDEPS dependence to LIBS.
7821 Tue Sep 15 15:32:02 1992 Ian Lance Taylor (ian@cygnus.com)
7823 * Makefile.in (install): if $(tooldir) exists, install as in
7826 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7828 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7829 .word is < -32768 or > 32767. The -J flag causes the error to be
7830 ignored. This is to catch over-sized switches generated by gcc on
7831 systems which don't support the broken .word hack.
7832 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7833 write.c (fixup_segment): check for signed .word overflow if
7834 WARN_SIGNED_OVERFLOW_WORD.
7836 * write.c (fixup_segment): fixed missing parens in expression
7837 checking for byte or word overflow.
7839 * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
7840 obj-coffbfd.c (fixup_segment): check for signed .word overflow if
7841 WARN_SIGNED_OVERFLOW_WORD.
7843 * obj-coffbfd.c (fixup_segment): fixed missing parens in
7844 expression checking for byte or word overflow.
7846 Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7848 Support for i386 coff
7849 * obj-coffbfd.h : added stuff
7850 * tc-i386.c (tc_coff_fix2rtype): new function
7851 * tc-i386.h : new coff defines
7853 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7855 * input-scrub.c (input_scrub_push): call input_file_begin, not
7857 messages.c (as_perror): print ": " between the passed in error and
7858 the strerror, like perror does.
7860 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)
7862 * Makefile.in: use gas_target instead of modifying target_cpu.
7863 From Steve Chamberlain:
7864 Makefile.in: Handle m68*-*-coff*.
7865 read.c, read.h: add mult argument to s_space
7867 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
7868 Motorola and MIT syntax; gas can now assemble either type of
7870 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
7871 From Steve Chamberlain:
7872 m68kcoff.mt: for m68k COFF.
7873 obj-coffbfd.c: (fixup_mdeps) added
7874 (size_section) removed bad sanity check
7875 (fill_section) added rs_machine_dependent case
7876 (write_object_file) call fixup_mdeps
7877 (fixup_segment) set fx_subsy to 0.
7878 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7880 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7883 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7885 * Makefile.in (LIBS): Include opcode library.
7887 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)
7889 * config/tc-m68k.c (get_num, case SEG_BIG): If only small integers
7890 including zero are accepted, pass +0.0.

7907 tc-i960.c (md_ri_to_chars): Always output bout object file in
7908 little endian byte order (used to use endianness of host).
7910 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7912 * config/tc-m68k.c (init_table): Now const. Always include 68851
7913 data, so that "bc" is available to 68040 cache instructions.
7914 Added "tt0", "tt1", and 68ec030 variants.
7915 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7916 (enum _register): Added TT0, TT1.
7917 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7918 line number correctly in "internal error" messages. Don't print
7919 architecture-mismatch message for operand errors.
7921 From Colin Smith (colin@wrs.com):
7922 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7923 than install_operand.
7925 Tue Aug 25 15:13:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7927 * listing.c (buffer_line): rewind to the start of include
7928 files, they might be included twice.
7930 * z8k.c, z8k.h, z8k.mt: z8000 support stuff
7932 Mon Aug 24 12:45:43 1992 Ian Lance Taylor (ian@cygnus.com)
7934 * Makefile.in: defined TARGET_CPU for C code so that it can choose
7935 one element of a family.
7937 * tc-m68k.c: use TARGET_CPU to choose default cpu type.
7939 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7940 so that we can assemble hand-written libgcc code.
7942 Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7944 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
7945 has already been formatted (but may still contain %-characters).
7948 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7950 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7951 written with indirection on the last two operands, which can be
7952 either data or address registers. Added a new operand type 'r'
7953 which accepts either register type. Added '(' to notend stuff in

8203 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8205 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8206 where gcc looks for it.
8208 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8210 * Makefile.in: Changed some lines to be less confusing for some

8280 * expr.c (operand): if can't work out what sort of operand it is,
8281 then look through FLT_CHARS for a hint.
8283 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8285 * Makefile.in, configure.in: removed traces of namesubdir,

8289 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8290 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8291 copyrights to '92, changed some from Cygnus to FSF.
8293 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8295 * expr.c: If an expression is single comma, then return with
8296 SEG_ABSENT rather than an error - since the sparc front end does
8297 really strange things with things like fbge,a
8299 * as.h: include bfd.h if using many sections
8300 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8301 local labels didn't work.
8302 * listing.c (list_symbol_table): don't core dump when there's no
8304 * write.c, write.h: call fix_new with the right number of args on

8309 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8311 * app.c: MRI compatibility - allow single quote to start a string.
8312 * as.c: fix typo recently introduced.
8313 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8314 * expr.c: Much rewriting, to accomodate MRI syntax for
8315 expressions. Also easier to read now.
8316 * listing.c: Put back defuns
8317 * read.c: modified to accept MRI syntax, put back listing pseudo
8318 ops so that an assembler built with NO_LISTING ignores list ops
8320 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8321 machine is a SPARC or a 29K.
8322 * config/obj-aout.c: added s_sect pseudo op
8323 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8324 fill in the timestamp.
8325 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8326 anymore, define all the relocs which the tc-<x> bit will use so we
8327 can translate from them to the coff types.
8328 * config/tc-a29k.c: reloc_type isn't ane enum any more
8329 * config/tc-m68k.c: Added NO_RELOC definition.
8331 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8333 * Makefile.in: put header files before C source for TAGS; remove
8334 references to non-existent syscalls.h.
8336 * read.c, write.c subsegs.c: back out the .bss changes.
8338 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8340 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8344 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8346 * symbols.c (local_label_name): symbols now start with ^A.
8348 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8349 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8350 generate these sections. .align: will use NOP_OPCODE or 0
8351 for padding. This is just for being nice to the
8354 * expr.c (operand): changed to generate local label "\001L0"
8355 starting with a ^A so that it is recognized as a local label.
8357 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8359 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8360 i/o opcodes - inb, inw, outb and outw. string manipulation with
8361 att syntax - scmp, slod, smov, ssca, ssto.
8363 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8364 to just after .file .
8366 In obj_crawl_symbol_chain() where it tries to put the external
8367 symbols apart, with the condition:
8368 (!S_IS_DEFINED(symbolP) &&
8369 !S_IS_DEBUG(symbolP) &&
8370 !SF_GET_STATICS(symbolP))
8371 it was moving too many symbols out. So I switch it back to the
8373 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8375 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8376 so that we don't use the F_RELFLG which make the linker complain
8377 that somebody has stripped the relocation info.
8379 Also, the AIX ld program require that the relocation table
8380 is sorted by r_vaddr like the standard ATT assembler does.
8382 [he also changed the sizeof(struct ...)'s into the coff
8383 style FOOSZ macros. I'm not sure this is right, but I can't
8384 remember why. xoxorich.]
8386 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

8395 * configure.in: use the new atof-ns32.c for ns32k.
8397 * write.c: comment change only.
8399 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8400 aren't yet integrated.
8402 * tc-i860.[hc]: blew off the dust. Something must still be done
8403 about conflicting relocation types.
8405 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8408 * tc-i960.c, tc-sparc.c: white space and comments only.
8410 * tc-a29k.h: delete duplicate macro definition.
8412 * new file atof-ns32k.c copied from hack's last unreleased gas.
8414 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8416 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8419 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8420 ChangeLog's prior to this are sketchy at best. I have logs.
8421 They just aren't ChangeLogs.
8428 version-control: never
