3948 * config/tc-mips.c: Added mips_4100 control, and support for
3949 accepting the 4100 as a MIPS architecture variant (md_begin,
3950 macro_build, mips_ip, md_parse_option). Adding suitable
3951 command-line OPTIONs, and updating the help text (md_show_usage).
3953 Wed Oct 18 13:20:32 1995 Ken Raeburn <raeburn@cygnus.com>
3955 * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
3956 BFD_ASSEMBLER is defined.
3958 * Use one active frag and one obstack per frag chain:
3959 * frags.c (frags): Variable deleted.
3960 (frag_alloc): New function.
3961 (frag_grow, frag_more, frag_variant, frag_now_fix,
3962 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
3964 (frag_new): Ditto. Verify that frch_last and frag_now match on
3965 entry and exit, and that old frag_now has non-zero type. Replace
3966 "know" uses with "assert". Use frag_alloc instead of mucking with
3968 * frags.h (frags): Declaration deleted.
3969 * subsegs.h (struct frchain): Add new field frch_frag_now.
3970 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
3972 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
3973 give it any stricter alignment than frchainS structures need. Do
3974 not initialize frags obstack. Set frag_now to point to
3975 dummy_obstack. Initialize absolute_frchain.
3976 (subseg_set_rest): Save and restore frag_now in frch_frag_now
3977 field of frchainS. Don't create new frags on section switch, and
3978 use frag_alloc when creating a new frag chain. For absolute
3979 section, set frchain_now to absolute_frchain. Verify that
3980 frch_last and frag_now match on entry and exit. Initialize
3981 per-chain obstack, and under gcc, set required alignment to that
3982 needed by fragS structure.
3984 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
3986 * stabs.c (get_stab_string_offset): Only copy input string if a
3987 fresh copy is needed, not if the section already exists.

3989 usually it will match. Could be made faster still by changing the
3990 memory allocation rules.
3991 (s_xstab): Cache section name to bypass repeated string
3994 * frags.c (frag_new): Deleted register declarations.
3996 * listing.c (frag_now): Don't declare.
3998 * as.c (chunksize): New variable.
3999 (debug_memory): New variable.
4000 (main): If debug_memory is set, reduce chunksize and

4008 * Makefile.in (distclean): Remove Makefile and config.status from
4009 testsuite directory.

4011 files within it that would be generated by running tests.
4013 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4014 frag_now_fix instead of accessing obstack info directly.
4015 * config/tc-arm.c (s_ltorg): Ditto.
4016 (md_assemble): Ditto.
4018 * config/tc-i386.c (md_assemble): Call frag_grow instead of
4021 Wed Oct 18 12:22:59 1995 Ken Raeburn <raeburn@cygnus.com>
4023 * stabs.c (aout_process_stab): Insert debug symbol into symbol
4024 chain after parsing value expression, if any, to avoid separating
4025 continued .stabs lines.
4027 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
4029 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
4030 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
4032 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
4034 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
4035 -mcom support and PPC_OPCODE_ANY for -many.
4036 (md_parse_option): Ditto.
4038 (md_begin): For duplicate instructions, print all duplicates
4041 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
4043 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
4044 common mode operation.
4045 (md_show_usage): Add -mcom to usage message.
4047 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>
4049 * expr.c (op_rank): Add O_symbol_rva.
4050 * expr.h (operatorT): Add O_symbol_rva.
4051 * read.c (cons_worker): Set O_symbol_rva when necessary.

4054 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>
4056 * config/tc-mips.c: Correct s_cons arguments. From Michael
4057 Joosten <joost@ori.cadlab.de>.

4061 * config/tc-ppc.c (ppc_macro): Make count unsigned.
4062 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
4063 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
4065 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
4066 make non-static. Change all users.
4067 * config/obj-coff.h (coff_n_line_nos): Declare.
4069 Fri Oct 6 16:24:27 1995 Ken Raeburn <raeburn@cygnus.com>
4071 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
4073 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
4075 * config/obj-elf.c (obj_elf_common): Convert specified byte
4076 alignment to power of two. Set size of local bss symbol.

4080 Fri Oct 6 15:22:25 1995 Ian Lance Taylor <ian@cygnus.com>
4082 * sb.c, macro.c: Decide whether to include <string.h> or
4083 <strings.h> just as as.h does.
4085 Fri Oct 6 09:55:33 1995 Doug Evans <dje@canuck.cygnus.com>
4087 * Makefile.in (site.exp): Fix setting of $srcdir.

4095 * doc/as.texinfo: Split out the NS32k family documentation,
4096 despite its being commented out for now.
4097 * doc/c-ns32k.texi: New file.
4099 * sb.c, macro.c: Include string.h.
4101 * Makefile.in (comparison): Only check *.o; we don't care if
4102 timestamps inserted by the native linker differ.
4104 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4105 if alignment stricter than 4 bytes is requested; in that case,
4106 align to a 4-byte boundary first.
4108 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
4110 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

4115 * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
4116 qualifiers and detect errors if present.
