1 Wed Sep 28 14:56:39 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
3 * expr.c (make_expr_symbol): No longer static. Use symbol_create,
4 not symbol_new, for symbols holding expression values.
5 * expr.h (make_expr_symbol): Move declaration here.
6 * write.c (fix_new_exp): Handle O_add by creating an
7 expression-valued symbol, and calling fix_new_exp recursively.
8 (adjust_reloc_syms): If a fixup's symbol value is a sum of an
9 undefined symbol and a constant, fold the constant into the fixup,
10 and refer to the undefined symbol directly. Then process the
11 fixup again from scratch.
12 (write_object_file): Before calling adjust_reloc_syms, make a pass
13 through the symbol list trying to resolve values.
15 * write.c (print_fixup): New routine, for debugging.

21 Wed Sep 28 11:50:40 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
23 * Makefile.in (gasp.o): Depends upon config.h.
25 * config/tc-mips.c: Include subsegs.h.
26 (md_apply_fix): If an unconditional b or bal overflows, and we are
27 not assembling PIC code, replace it with a j or jal.
29 * config/tc-mips.c (md_apply_fix): Correct branch overflow test.
30 Use as_bad_where and as_warn_where rather than as_bad and as_warn.
32 Mon Sep 26 17:15:59 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
34 * write.c (write_relocs): Add file name and line number to
35 as_fatal calls. Handle bfd_reloc_overflow case specifically when
36 RELOC_EXPANSION_POSSIBLE.
38 Fri Sep 23 16:11:28 1994 Ken Raeburn <raeburn@cujo.cygnus.com>
40 * as.h (USE_STDARG, USE_VARARGS): Define one or neither of these

45 default definitions matching what we were doing before.
46 (as_tsktsk): Remove the non-stdarg, non-varargs version, and
47 always use the varargs form if not using stdarg. It's safe to
48 always use vfprintf, because libiberty will provide it if the
49 native system doesn't. Also, always make format be const.
50 (as_warn, as_warn_where, as_bad, as_bad_where, as_fatal): Ditto.
52 Fri Sep 23 14:42:34 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
54 * config/tc-mips.c (load_register): Always use addiu when adding a
55 constant to $zero--no need to use daddiu.
56 (macro): Hack the -mips3 overflow tests to not fail when offsetT
59 * symbols.h (copy_symbol_attributes): Declare.
61 Thu Sep 22 21:58:24 1994 Ken Raeburn <raeburn@cujo.cygnus.com>

65 (listing_newline): Check filename as well as line number when
66 deciding whether to record it.
67 (list_symbol_table) [S_IS_REGISTER]: Check that S_IS_REGISTER is
68 false (if defined) as well as checking for reg_section.
69 (listing_listing): Iterate fetching lines while line number is too
70 low, and we haven't run off the end of the input file.
72 * config/vms-conf.h: Changed HAVE_DELETE to HAVE_REMOVE.
74 Thu Sep 22 13:39:10 1994 Kung Hsu (kung@x1.cygnus.com)

83 * config/ho-*.h: Now-unused files deleted.
85 * symbols.c (copy_symbol_attributes): New function. Copies BFD
86 symbol flags and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
87 (resolve_symbol_value, case O_symbol): Call it, if X_add_number is
88 zero. Don't call obj_frob_forward_symbol.

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

113 (ppc_es): Clear ppc_current_block.
114 (ppc_frob_symbol): Set the value of a C_STSYM symbol to the offset
115 from the csect of the enclosing block.
117 * config/tc-mips.c (insns_since_cache_access): Remove.
118 (append_insn): Remove setting of insns_since_cache_access, and
119 special 4600 handling; it turns out not to be required.
121 Tue Sep 20 16:13:18 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
123 * config/tc-mips.c (md_shortopts): Remove E.
124 (md_longopts): Add EB and EL.
125 (md_parse_option): Handle -EB and -EL as separate options, rather
126 than as a single -E option with an argument.
128 Mon Sep 19 12:42:05 1994 Jeff Law (law@snake.cs.utah.edu)
130 * config/tc-hppa.c (hppa_fix_adjustable): Reject reductions
131 involving global symbols too.
133 Mon Sep 19 12:12:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
135 * as.h: Test NEED_DECLARATION_*, not NEED_*_DECLARATION.
137 * configure.in: Test for remove, not delete. Fix cross-assembler
139 * as.h: Test HAVE_REMOVE, not HAVE_DELETE; define unlink to
142 * read.c (pseudo_set, case O_symbol): If
143 OBJ_COPY_SYMBOL_ATTRIBUTES is defined, invoke it.
144 [BFD_ASSEMBLER]: Copy BSF_FUNCTION setting too.

147 Wed Aug 10 19:15:30 1994 Pat Rankin (rankin@eql.caltech.edu)
149 * config/obj-vms.h (DSG_S_C_UBITU, DST_K_VFLAGS_DSC, DST_K_TS_ATOM,
150 many others): new macros; values obtained from "DSTRECRDS.SDL".
151 * config/obj-vms.h (various): use them.
152 (USE_BITSTRING_DESCRIPTOR): new macro, for selecting bitfield
153 representation (only enum bitfields can avoid being bitstrings).
154 (bitfield_suffix, setup_basic_type): new routines.
155 (VMS_typedef_parse): use them. Now recognize bitfields of all
156 integral types, not just type `int'. Caveat: the representation
157 used for bitfields still does not work for objects placed in
158 registers, and gcc's optimizer sometimes puts small structs there.
160 Tue Jun 14 17:31:44 1994 Pat Rankin (rankin@eql.caltech.edu)
162 * read.c (s_text) [#if OBJ_VMS]: clear the IN_DEFAULT_SECTION
164 * config/obj-vms.h (IN_DEFAULT_SECTION): define this macro.
165 (tc_frob_label): define this to call vms_check_for_special_label,
166 and declare the latter.
167 * config/obj-vms.c (vax_g_doubles): declare this file-scope
169 (const_flag): initialize to IN_DEFAULT_SECTION instead of 0.
170 (vms_check_for_special_label): new routine (tc_frob_label).
171 (VMS_TBT_Routine_End): don't bother checking for `gcc_compiled.'
172 and `gcc2_compiled.' labels; they won't reach here any more.
173 (VMS_typedef_parse) [case 'r']: for types `double' and `complex
174 double', use `vax_g_doubles' flag to select type of double.
175 (VMS_write_object_file) [traceback setup]: don't pass symbols
176 with the IN_DEFAULT_SECTION attribute to the TBT_Routine_Begin
177 and TBT_Routine_End functions.
179 Mon Jun 6 20:52:20 1994 Pat Rankin (rankin@eql.caltech.edu)
181 * config/obj-vms.c (VMS_TBT_Routine_End): cache the result of
182 S_GET_VALUE() to avoid many repeated function calls.
183 (VMS_Check_For_Main) [#if HACK_DEC_C_STARTUP]: capitalize
184 _C$MAIN_ARGS in advance, in case -h3 (leave symbol name as-is)
185 gets requested. [All the HACK_DEC_C_STARTUP code appears to
186 be obsolete; gcc does it automatically for vms target. It's
187 also misnamed, because it is for the "VAX C" run-time library,
188 not the newer "DEC C" one which has much different startup code.]
189 {various}: use `S_SET_xxx(symbol,new_value)' rather than
190 `S_GET_xxx(symbol) = new_value'.

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

295 * gdbinit.in: New file, created from old .gdbinit.
297 * aclocal.m4 (GAS_GDBINIT): Deleted.
298 * configure.in: Don't use it. Instead, generate .gdbinit from
299 gdbinit.in. Don't substitute cpu_type, obj_format, emulation,
300 atof. Switched order of AC_LINK_FILES arguments. Use AC_PREREQ
301 to ensure that older versions of autoconf aren't used.
302 * Makefile.in: Added @configure_input@ line.

393 * read.c (read_a_source_file): The second argument to as_where is
394 unsigned int *, not int *.
396 Thu Sep 8 17:18:24 1994 Kung Hsu (kung@mexican.cygnus.com)
398 * config/obj-ecoff.h : Change names to OBJ_GENERATE_ASM_LINENO,
399 and generate_asm_lineno.

434 * Makefile.in (CC_FOR_TARGET, NM_FOR_TARGET, OBJDUMP_FOR_TARGET,
435 install, uninstall): Don't use "brokensed" hack any more, the new

441 * configure.in: Use them. Use AC_ARG_PROGRAM (now provided by
442 autoconf) instead of my hacked-up AC_PROGRAM_TRANSFORM_NAME. Move
443 test for CROSS_COMPILE just before AC_FUNC_ALLOCA, and emit a
444 message to try to ease confusion about autoconf's
445 "cross-compiling" message.
446 * acconfig.h (NEED_DECLARATION_MALLOC, NEED_DECLARATION_FREE,
447 NEED_DECLARATION_ERRNO): Renamed from NEED_*_DECLARATION.

1583 * config/obj-coffbfd.c (fill_section): Check COFF_NOLOAD_PROBLEM
1584 also before setting STYP_NOLOAD for .bss section.

1650 * as.c (main): If tc_init_after_args is defined, invoke it after
1651 all arguments have been processed.
1653 Some changes to help Apollo support, from troy@cbme.unsw.edu.au:
1654 * as.c (perform_an_assembly_pass) [TE_APOLLO]: Create .wtext

1658 Thu Apr 21 15:50:04 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1660 * config/tc-mips.c (append_insn): Permit branches to be switched
1661 with the preceding instruction even if .set nobopt has been seen.
1662 .set nobopt actually controls whether to bring up an instruction
1663 from the branch target, which gas does not currently support.

1721 Thu Apr 14 15:12:36 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1723 * expr.c (operand): Try to parse "0f" and "0b" sequences as
1724 floating point and binary numbers respectively; if it doesn't
1725 work, treat them as local labels.
1727 * Makefile.in: Make $(OBJS) depend on $(ALL_OBJ_DEPS).
1728 * configure.in: Set ALL_OBJ_DEPS in output Makefile.
1730 Based on suggestions from <BAILEY@hmivax.humgen.upenn.edu>
1732 * vmsconf.sh: In generated file, get ".obj" suffix right, build
1733 source files from other directories into objects in the current
1734 directory, and specify PSECT attributes explicitly to linker.
1735 Also added missing label.
1736 * Makefile.in (stamp-mk.com): Reference new variable

1803 elf_tc_make_sections stuff. It was there to support PA braindamage
1804 which has been fixed, and in the case of elf_tc_make_sections is
1805 redundant with elf_tc_final_processing.
1807 Wed Apr 6 20:48:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1851 * config/tc-sparc.c (tc_gen_reloc): Add a gruesome hack to get
1852 cross section PC relative relocs right for COFF and ELF.
1854 Mon Mar 28 14:38:23 1994 Ken Raeburn (raeburn@cujo.cygnus.com)

1883 branch with an instruction that uses $at, in case the branch is
1885 (macro): If EMBEDDED_PIC, case M_JAL_A may use $at.
1886 (md_pcrel_from): If not OBJ_AOUT, return 4 for an undefined symbol
1887 to make it pcrel_offset.
1888 (tc_gen_reloc): If not OBJ_AOUT, set the reloc addend to
1889 reloc->address; another gruesome hack to get gas reloc handling to
1892 Thu Mar 24 21:29:29 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1894 * config/tc-alpha.c (alpha_ip): Only set GP prolog size if using
1897 (emit_insn): New function.
1898 (md_assemble): Call it.
1899 (alpha_force_relocation): Handle BFD_RELOC_26, for call_pal
1901 (lituse_pending): New variable. Set by anything that generates a
1902 LITERAL reloc, cleared by anything that generates a LITUSE reloc,
1903 tested by code that might want to emit a LITUSE reloc.
1904 (emit_unaligned_io): New function. Currently calls md_assemble,
1905 but it should eventually be converted to generate the insn itself
1906 and call emit_insn directly.
1907 (emit_load_unal, emit_store_unal, emit_byte_manip_r,
1908 emit_extract_r, emit_insert_r, emit_mask_r, emit_sign_extend,
1909 emit_bis_r): Likewise.
1910 (alpha_ip, case 'I'): Handle with BFD_RELOC_23.
1911 (alpha_ip, label get_macro): Don't emit the final instruction if
1913 (alpha_ip, case 'B', subcase 'd'): New case, for subword and
1914 unaligned memory access macros.
1915 (md_apply_fix): Handle BFD_RELOC_26. Generate an error message if
1916 the value can't be resolved.
1918 Wed Mar 23 16:06:08 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1920 * config/tc-mips.c (md_parse_option): For -membedded-pic, force
1921 the -G value to 0x7fffffff. For SVR4 PIC options, don't call
1922 bfd_set_gp_size here, it's done in md_begin. Don't permit -G with
1924 (mips_force_relocation): New function.
1925 (md_apply_fix): Set fixP->fx_done appropriately.
1926 (s_change_sec): For EMBEDDED_PIC, change .data and .rdata to

1934 * config/tc-mips.c (enum mips_pic_level): New enum.
1935 (mips_pic): Change from int to enum mips_pic_level. Change all
1936 uses (0 becomes NO_PIC, 2 becomes SVR4_PIC).
1937 (load_address): Handle EMBEDDED_PIC.
1938 (macro): Handle EMBEDDED_PIC in all PIC cases.
1939 (md_parse_option): Accept -membedded-pic to use EMBEDDED_PIC. If
1940 OBJ_ELF, accept -KPIC and -call_shared to use SVR4_PIC and accept
1941 -non_shared to use NO_PIC (this is how the Irix 5 assembler
1942 works). Do not permit -G with SVR4_PIC.
1943 (s_abicalls): Warn if -G was used, and force -G 0.
1944 (tc_gen_reloc): Set reloc->addend to 0 for a PC relative reloc for
1945 anything but a.out, not just for ELF. For ECOFF, don't generate a
1946 BFD_RELOC_16_PCREL_S2 reloc unless using EMBEDDED_PIC.
1948 * config/obj-ecoff.h (obj_sec_sym_ok_for_reloc): Define to be 1.
1950 Sun Mar 20 16:31:55 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1952 * config/tc-hppa.c (create_new_space): Use ints, not chars as
1953 parameters to avoid losing when compiling with HP CC.
1954 (create_new_subspace, update_subspace, fix_new_hppa): Likewise.
1956 Sun Mar 20 14:43:14 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
1958 * Makefile.in (config-stamp): If `defs' is defined, emit a
1959 preprocessor directive to create a macro named by this value into
1960 config.new; don't explicitly go for BFD_ASSEMBLER.
1961 * configure.in: Define `defs', not `BFDDEF'. Set it to
1962 MANY_SEGMENTS for any obj-coffbfd target.
1963 * config/obj-coffbfd.h (BFD_HEADERS, BFD): Define.
1964 * config/i386coff.mt (TDEFINES): Don't define BFD, MANY_SEGMENTS,
1966 (LOCAL_LOADLIBES): Deleted.
1967 * config/m68kcoff.mt (TDEFINES): Don't define those macros.
1968 * config/m88kcoff.mt (TDEFINES): Ditto.
1969 * config/ebmon29k.mt: Deleted.

1972 * config/sparc.mt: Deleted.
1973 * config/h8300.mt (LOCAL_LOADLIBES, TDEFINES): Deleted.

1994 bfd_set_symtab is called.
1995 (dump_section_relocs): Note whether a symbol is a section symbol
1997 (adjust_reloc_syms): For now, always supply an absolute symbol for
1998 fixups without symbols but not yet `done'. Use section_symbol to
1999 get the symbol, instead of going directly for abs_symbol.
2000 (write_relocs) [DEBUG4]: Abort if any symbol referred to by a
2001 reloc is not a section symbol and is not in the symbol table.
2002 (set_symtab): New function, broken out from write_object_file.
2003 Counts symbol table instead of relying on an earlier count.
2004 (write_object_file): Call set_symtab, but do it after potentially
2005 invoking the *_frob_file macros. Don't bother counting symbols.
2006 Call symbol_remove, instead of expanding it in place. Moved the
2007 conditionalized `object_file_size' declaration down to
2008 conditionalized block where it's used. When using the absolute
2009 symbol for a fixup without a symbol, set sy_used_in_reloc.
2010 (write_object_file) [BFD_ASSEMBLER]: Call section_symbol to get
2011 the correct symbol for the absolute section.
2013 * subsegs.c (section_symbol): Use symbol_new instead of
2014 symbol_make, since we may want it to go into the symbol table.
2015 Make the new symbol have internal linkage. If
2016 obj_sec_sym_ok_for_reloc says it's okay, use the BFD section
2017 symbol with the newly created GAS symbol.
2018 (obj_sec_sym_ok_for_reloc): Default to always returning 0.
2019 * config/obj-aout.h (obj_sec_sym_ok_for_reloc) [BFD_ASSEMBLER]:

2024 (in_signed_range): New function.
2026 (sparc_ip, case 'i'): Use BFD_RELOC_SPARC13, not _BASE13.
2027 (sparc_ip, label "immediate"): Reject constants for pcrel
2028 instructions only if the relocation type indicates a "call"
2029 instruction and the offset is within range of a "jmpl %g0". If
2030 it's not in range, use the absolute section symbol plus an offset.
2031 (md_apply_fix): Use in_signed_range. Combined _SPARC13 and
2033 (tc_gen_reloc): Permit BFD_RELOC_SPARC13.
2035 * config/ic960coff.mt (TDEFINES): Fixed typo (MANY_SECTIONS, not
2038 * configure.in: Eliminated all targets using obj-coff but not
2039 defining BFD_ASSEMBLER; I think all such targets that are
2040 supported will be matched by real CPU-OS combinations earlier in
2042 (targets *-*-coff*, *-sysv*, *-*-sco*, *-*-sysv32): Deleted. Made
2043 some comments about the dpx2 configuration, but left it disabled,
2044 since it couldn't be reached before.
2045 (target a29k-amd-ebmonold): Deleted.
2047 Thu Mar 17 13:36:09 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2055 the 'j' operand if there are no further alternatives for this
2058 * config/obj-coffbfd.c (adjust_stab_section): Initialize
2059 stabstrseg to SEG_UNKNOWN, not -1. After loop, check whether it
2060 is not SEG_UNKNOWN rather than checking whether it is >= 0.
2062 * config/tc-mips.c (mips_align): Take new argument, label, and use
2063 it instead of global insn_label.
2064 (s_align, s_cons, s_float_cons, s_gpword): Save insn_label before
2065 call to mips_emit_delay and pass it to mips_align.
2067 Wed Mar 16 11:54:12 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2069 * config/tc-hppa.c (pa_equ): Handle both .reg and .equ correctly.
2071 * config/tc-hppa.c (pa_callinfo): Accept "millicode" as an
2072 argument to a .callinfo directive. Don't loop forever on errors.
2074 * config/tc-hppa.c (pa_equ): Use pa_parse_number so that we can
2075 use pre-defined registers as arguments.

2080 S_IS_EXTERNAL when deciding whether to discard a symbol.
2082 * config-gas.com: Scan Makefile.in, not version.c, for current
2083 version number. Delete all versions of temp files when finished
2084 with them. Create config.h.
2086 * config/obj-vms.c (VMS_Initialized_Data_Size): Cache symbol
2087 values to reduce number of lookups with S_GET_VALUE. Skip debug
2088 symbols to avoid "a really nasty bug". (From Holger Teutsch,
2089 holger@botbso.rhein-main.de.)
2090 (VMS_write_object_file): For "__vt.*" symbols, set S_GET_OTHER
2091 field. (Also from Holger Teutsch.) Watch for a would-be register
2092 mask that spans frags.
2094 * config/obj-coffbfd.c (obj_coff_line): Set symbol lnno field with
2095 this_base, not line_base. (Patch from Andreas Arens,
2096 ari@obelix.av.rwth-aachen.de.)
2098 * config/obj-aout.c (obj_crawl_symbol_chain): Retain symbols that
2099 look local if they're exported or undefined. Used to be done for
2102 * read.c (s_lcomm, s_comm): Print symbol name being redefined.
2103 Get it from the looked-up symbol, instead of using the string from
2104 the input stream, which is no longer null-terminated.
2105 (LEX_PCT): New macro, defaults to 0.
2106 (lex_type): Use it for `%'.
2108 * config/tc-vax.c (md_parse_option): Handle `-h#' option for VMS.

2158 * config/tc-mips.c (mips_ip): Accept numbers between 0x8000 and
2159 0xffff for 'j' to be compatible with MIPS assembler. These

4227 OPTIONAL_REGISTER_PREFIX if either is already defined.
4229 * config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
4231 * configure.in: Set bfd_gas for all sparc targets. Added facility
4232 for keeping or rejecting configurations still under development;
4233 default is to assume production environment, and reject configs
4234 still being worked on. Mark Elf configurations (except sparc and
4235 i386) as developmental. Deleted cases matching some generic names
4236 in favor of more specific names. (E.g., when we get Alpha
4237 support, we'll still only support VMS for Vax.)

4251 against placing additional object-file dependent code here. Warn
4252 against contaminating all of GAS with the internals of tc-hppa.c
4253 through inclusion of tc-hppa.h. Delete all forward declarations
4254 for functions only used within tc-hppa.c, likewise for structures,
4255 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
4256 conditional code in a few small places.
4258 * config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
4259 structures, global variables, forward declarations together.
4260 Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
4261 conditional code -- try to group conditional code together
4262 into a few places. Make all functions and variables which
4263 are only used within tc-hppa.c static. PARAMize all functions.
4264 Add comments to functions. Delete unused functions, variables,
4265 #defines, etc. Delete unused members within structures. Delete
4266 ldil;ble hacks -- it is believed they were installed to work
4267 around old gas bugs. Avoid using mixed case for local
4268 functions, variables, and structures. Fix formatting problems
4269 not found by GNU-indent. Add FIXME notices for things which
4270 should be worked on the near future. Delete lots of old
4271 useless (1.36 PA-SOM) code.

4288 * config/tc-hppa.c: Likewise.
4290 * config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
4291 of elf32_symbol_type.
4292 (pa_export_args): Likewise.
4293 (elf_hppa_final_processing): Likewise.
4294 (pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed

4299 * config/tc-hppa.c: (md_section_align): Align all sections to
4300 a multiple of the section alignment rather than always a
4303 * config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
4304 bits are zero (eg they specify no relocations), then do not even
4305 bother adding their entries to thesymextn section.

4348 instead add a second loop over special_chars. Set alignment
4349 of text, data and bss sections to 4.
4350 (pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
4352 (reloc): Don't return 8 and 16 bit non-PC relative relocations on
4353 ELF, since the ELF object format does not have these type of
4354 relocations. Change the abort into as as_bad and return
4355 BFD_RELOC_NONE to silence compiler warnings.
4356 (md_assemble): Keep track of the instruction size. Allow white
4357 space between the $ and the constant for compatibility with older

6742 a29k .bss section; the mondfe program doesn't like it.

6763 source directory, if that's not the current directory.
6765 * configure.in (per-host): Accept MIPS host with BSD version

6791 avoid some redefinition complaints on some systems.
6792 (const, volatile): Don't need these conditionally defined if we
6793 use CONST and VOLATILE from ansidecl.h.
6794 (seg_name): Use CONST, not const.
6796 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
6798 * config/tc-mips.c: Reindented to GNU standards.
6800 Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
6802 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
6803 (fixup_segment): Add a29k special case; the linker is not prepared
6804 to see a segment offset here.
6806 * app.c (do_scrub_next_char): Added new state, 10, modifying state
6807 9 to only keep a space in between identifier characters.
6809 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
6811 * Makefile.in: add dvi target; as-$(config).texinfo might live in
6812 srcdir, might be in objdir.
6814 * doc/Makefile.in: dvi depends on as.dvi

6842 dropping a space immediately following an identifier.
6843 * expr.c, write.c: Rewrote assert expressions to not use multiple
6844 lines; I don't think that can be done portably.
6845 * config/tc-mips.c (macro): Use $AT if target register is zero in
6846 load instruction, which it can be for a floating point load.

6859 * config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
6860 z8k-opc.h, not z8k.h.
6862 * config/obj-coffbfd.c (obj_coff_endef): Correct test for .bf
6865 Fri Mar 12 18:33:36 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)

6920 prototypes for all static functions. Moved existing minimal
6921 debugging format support info #ifndef OBJ_ECOFF blocks.

6970 * make-gas.com: Find obstack.obj if it's not in the current
6972 * read.c (s_ignore): Don't declare is_end_of_line. It's
6973 redundant, and triggers a VMS gcc compiler bug.
6975 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
6976 current segment as an argument. (Ignored in all cases but VMS.)
6977 All callers and definitions changed.

6995 argument to s_ignore. Put "#if 0" around unused code.
6996 (obj_pseudo_table): Use s_ignore instead of do-nothing routines.
6997 Call elf_xstabs for .stabs and .xstabs operators.
6999 * config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
7001 * write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
7004 * configure.in: mips-bsd configuration was missing format spec.
7007 * Makefile.in (Makefile): Depends on configure.in.

7304 * expr.c (operand): If character other than comma or newline is a
7305 logical end-of-line character, use the newline case.

7307 (operand): Set X_add_number field for floating-point numbers.
7308 (operand): Treat zero byte as end-of-operand.
7310 * configure.in (per-target): Look for with_bfd_assembler option.
7311 For now, only accept "no", until the merge is done.
7313 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
7314 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,

7320 * expr.c: Add "const" modifier to hex_value.
7321 * symbols.c: Finish conversion to S_* macros in the VMS only
7322 parts of the program. Add "const" modifier to
7323 md_[long,short]_jump_size. Remove declaration of const_flag
7324 (which will be declared in obj-vms.h).
7325 * write.c: Add "const" modifier to md_[long,short]_jump_size.
7326 Fix arguments to VMS_write_object_file.
7327 * config-gas.com: New file. Script for VMS systems to set up the
7328 configuration to build gas for VMS, and create config.status.

7335 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
7336 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
7337 types of malformed stabs. Change parsing algorithm so that we are
7338 more certain of having all of the information that we need on hand.
7339 * obj-vms.c (final_forward_reference): New function, used to help
7340 resolve the data types of as many struct elements as possible

7344 * obj-vms.c (VMS_write_object_file): Define all vtable psects
7345 as symbols as well in the object file. Look for external functions

7358 SEG_DATA or SEG_E1 if needed.
7359 (s_lcomm): Likewise with bss_section.
7360 (s_fill): Use memset, not bzero.

7387 mapping to segT enum values.
7388 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
7389 if these are used or defined, if BFD_ASSEMBLER.
7390 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
7391 subseg_new split into two functions.
7392 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
7394 * as.h (volatile): Don't define if already defined.
7395 (had_errors, had_warnings): Provide prototypes for ANSI C even if

7398 declare with format attribute for -Wformat checking.
7400 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
7402 * app.c, config/tc-*.c: Don't include read.h, since it is already

7415 * config/te-sco386.h (LOCAL_LABEL): Don't define.
7416 (DOT_LABEL_PREFIX): Define.

7418 name rather than L0\001.
7419 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
7421 * symbols.c, symbols.h (local_bss_counter): Removed.
7422 * write.c (write_object_file): bss no longer uses
7423 local_bss_counter. Pass correct data and bss size to
7424 VMS_write_object_file.

7430 (size_section): Restored sanity check.
7431 (do_relocs_for): Base section address on s_paddr rather than
7432 computing it. Adjust a29k R_IHIHALF special case to account for

7434 reclos, set s_relptr to 0. Set relocation size in object_headers.
7435 (fill_section): Always set s_vaddr here, removing
7436 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
7437 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
7438 Set STYP_INFO for .comment.
7439 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
7440 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

7442 H_{SET,GET}_* macros.
7443 (do_linenos_for): Set lineno size in object_headers.
7444 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
7445 set s_vaddr here. If string_byte_count remains 4, set it back to
7446 0, and only write strings out if there are some. Call
7447 fill_section before do_relocs_for and do_linenos_for.
7448 (obj_coff_section): Handle optional quoted second argument giving
7449 section characteristics.
7450 (obj_coff_bss): Added to handle .bss.
7451 (obj_coff_ident): Added to handle .ident (puts string in .comment

7471 (do_scrub_next_char): For \", return " not '.
7472 (symbol_chars): Now const.
7474 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
7475 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
7477 * config/obj-coff.h: Don't use #elif.
7479 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't

7511 (obj_coff_endef): Don't merge labels or symbols awaiting forward
7512 definitions, and don't merge tags with non-tags. Check for .bf
7513 rather than just checking whether the second character is b and
7514 the third character is f.
7515 (obj_coff_val): gcc can generate values which we don't handle

7519 (yank_symbols): Don't merge labels.
7520 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

7666 could be doing emulation.
7668 Thu Nov 19 11:47:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
7671 * doc/Makefile.in, doc/all.m4, doc/as-all.texinfo, doc/as.texinfo:
7674 Tue Nov 10 09:49:24 1992 Ian Lance Taylor (ian@cygnus.com)

7700 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
7702 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
7703 constant will not fit in an immediate field.
7704 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.

7739 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
7741 * Support for i386-sysv.
7742 obj-coffbfd.c (do_relocs_for, write_object_file): set segment

7780 * tc-z8k.c: lots of bug fixes
7782 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
7784 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
7785 #elif, since it is not supported by old compilers.
7786 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
7787 couple of expressions in tc-m68k.c.
7789 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7791 * read.c (cons): If NO_RELOC is defined, use it.
7793 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.

7812 * listing.c (debugging_pseudo): Add stabs and stabn as things to
7815 Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com)
7817 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
7818 sections starting from zero, rather than making them consecutive.
7819 This makes subsequent reloc calculations easier, esp if the object
7820 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
7821 allocate lcomm in .data rather than in .bss. It seems that some
7822 tools can't cope with a non-zero sized bss before linkage.
7824 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7826 * tc-m68k.c: Replace "enum m68k_architecture" with "int"

7830 "-mno-688[58]1" options.
7832 * tc-m68k.c: Added CPU32 support.

7845 * Makefile.in (install): if $(tooldir) exists, install as in
7848 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
7850 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
7851 .word is < -32768 or > 32767. The -J flag causes the error to be
7852 ignored. This is to catch over-sized switches generated by gcc on
7853 systems which don't support the broken .word hack.
7854 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
7855 write.c (fixup_segment): check for signed .word overflow if
7856 WARN_SIGNED_OVERFLOW_WORD.
7858 * write.c (fixup_segment): fixed missing parens in expression
7859 checking for byte or word overflow.

7875 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
7877 * input-scrub.c (input_scrub_push): call input_file_begin, not
7879 messages.c (as_perror): print ": " between the passed in error and
7880 the strerror, like perror does.
7882 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

7899 (fixup_segment) set fx_subsy to 0.
7900 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
7902 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
7905 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7907 * Makefile.in (LIBS): Include opcode library.
7909 Fri Sep 4 18:20:56 1992 Ken Raeburn (raeburn@cygnus.com)

7929 tc-i960.c (md_ri_to_chars): Always output bout object file in
7930 little endian byte order (used to use endianness of host).
7932 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
7934 * config/tc-m68k.c (init_table): Now const. Always include 68851
7935 data, so that "bc" is available to 68040 cache instructions.
7936 Added "tt0", "tt1", and 68ec030 variants.
7937 (md_assemble): Complain if 68000 (only) and 68881 are specified.
7938 (enum _register): Added TT0, TT1.
7939 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
7940 line number correctly in "internal error" messages. Don't print
7941 architecture-mismatch message for operand errors.
7943 From Colin Smith (colin@wrs.com):
7944 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
7945 than install_operand.

7961 * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
7962 so that we can assemble hand-written libgcc code.

7970 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
7972 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
7973 written with indirection on the last two operands, which can be
7974 either data or address registers. Added a new operand type 'r'
7975 which accepts either register type. Added '(' to notend stuff in
7976 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

8088 characteristics have been), default to 68020. Don't need extra
8089 quotes around error string.

8222 * write.c (write_object_file): For b.out format, round up section
8223 start addresses to match required alignment.
8225 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
8227 * Makefile.in (install): Install into $(tooldir)/bin, since that's
8228 where gcc looks for it.
8230 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
8232 * Makefile.in: Changed some lines to be less confusing for some

8302 * expr.c (operand): if can't work out what sort of operand it is,
8303 then look through FLT_CHARS for a hint.
8305 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
8307 * Makefile.in, configure.in: removed traces of namesubdir,

8311 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
8312 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
8313 copyrights to '92, changed some from Cygnus to FSF.
8315 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8317 * expr.c: If an expression is single comma, then return with
8318 SEG_ABSENT rather than an error - since the sparc front end does
8319 really strange things with things like fbge,a
8321 * as.h: include bfd.h if using many sections
8322 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
8323 local labels didn't work.
8324 * listing.c (list_symbol_table): don't core dump when there's no
8326 * write.c, write.h: call fix_new with the right number of args on
8328 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
8331 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
8333 * app.c: MRI compatibility - allow single quote to start a string.
8334 * as.c: fix typo recently introduced.
8335 * as.h : Don't include aout/reloc.h - it's not right for COFF!
8336 * expr.c: Much rewriting, to accomodate MRI syntax for
8337 expressions. Also easier to read now.
8338 * listing.c: Put back defuns
8339 * read.c: modified to accept MRI syntax, put back listing pseudo
8340 ops so that an assembler built with NO_LISTING ignores list ops
8342 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
8343 machine is a SPARC or a 29K.
8344 * config/obj-aout.c: added s_sect pseudo op
8345 * config/obj-coffbfd.c: lints, set the filehdr flags right and
8346 fill in the timestamp.
8347 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
8348 anymore, define all the relocs which the tc-<x> bit will use so we
8349 can translate from them to the coff types.
8350 * config/tc-a29k.c: reloc_type isn't ane enum any more
8351 * config/tc-m68k.c: Added NO_RELOC definition.
8353 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
8355 * Makefile.in: put header files before C source for TAGS; remove
8356 references to non-existent syscalls.h.
8358 * read.c, write.c subsegs.c: back out the .bss changes.
8360 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
8362 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
8366 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
8368 * symbols.c (local_label_name): symbols now start with ^A.
8370 * read.c, subsegs.c, write.c obj-coff.c: added handling of
8371 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
8372 generate these sections. .align: will use NOP_OPCODE or 0
8373 for padding. This is just for being nice to the
8376 * expr.c (operand): changed to generate local label "\001L0"
8377 starting with a ^A so that it is recognized as a local label.
8379 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
8381 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
8382 i/o opcodes - inb, inw, outb and outw. string manipulation with
8383 att syntax - scmp, slod, smov, ssca, ssto.
8385 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
8386 to just after .file .
8388 In obj_crawl_symbol_chain() where it tries to put the external
8389 symbols apart, with the condition:
8390 (!S_IS_DEFINED(symbolP) &&
8391 !S_IS_DEBUG(symbolP) &&
8392 !SF_GET_STATICS(symbolP))
8393 it was moving too many symbols out. So I switch it back to the
8395 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
8397 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
8398 so that we don't use the F_RELFLG which make the linker complain
8399 that somebody has stripped the relocation info.
8401 Also, the AIX ld program require that the relocation table
8402 is sorted by r_vaddr like the standard ATT assembler does.
8404 [he also changed the sizeof(struct ...)'s into the coff
8405 style FOOSZ macros. I'm not sure this is right, but I can't
8406 remember why. xoxorich.]
8408 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
8410 * Makefile.in, configure.in, doc: use the doc. Build it, install

8415 * read.c: white space and comments only.
8417 * configure.in: use the new atof-ns32.c for ns32k.
8419 * write.c: comment change only.
8421 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
8422 aren't yet integrated.
8424 * tc-i860.[hc]: blew off the dust. Something must still be done
8425 about conflicting relocation types.
8427 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
8430 * tc-i960.c, tc-sparc.c: white space and comments only.
8432 * tc-a29k.h: delete duplicate macro definition.
8434 * new file atof-ns32k.c copied from hack's last unreleased gas.
8436 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
8438 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
8441 * nearly everything. flush ChangeLog, package as gas-1.92.1.
8442 ChangeLog's prior to this are sketchy at best. I have logs.
8443 They just aren't ChangeLogs.
8450 version-control: never
