3947 * config/tc-mips.c: Added mips_4100 control, and support for
3948 accepting the 4100 as a MIPS architecture variant (md_begin,
3949 macro_build, mips_ip, md_parse_option). Adding suitable
3950 command-line OPTIONs, and updating the help text (md_show_usage).
3952 Wed Oct 18 13:20:32 1995 Ken Raeburn <raeburn@cygnus.com>
3954 * subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
3955 BFD_ASSEMBLER is defined.
3957 * Use one active frag and one obstack per frag chain:
3958 * frags.c (frags): Variable deleted.
3959 (frag_alloc): New function.
3960 (frag_grow, frag_more, frag_variant, frag_now_fix,
3961 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
3963 (frag_new): Ditto. Verify that frch_last and frag_now match on
3964 entry and exit, and that old frag_now has non-zero type. Replace
3965 "know" uses with "assert". Use frag_alloc instead of mucking with
3967 * frags.h (frags): Declaration deleted.
3968 * subsegs.h (struct frchain): Add new field frch_frag_now.
3969 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
3971 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
3972 give it any stricter alignment than frchainS structures need. Do
3973 not initialize frags obstack. Set frag_now to point to
3974 dummy_obstack. Initialize absolute_frchain.
3975 (subseg_set_rest): Save and restore frag_now in frch_frag_now
3976 field of frchainS. Don't create new frags on section switch, and
3977 use frag_alloc when creating a new frag chain. For absolute
3978 section, set frchain_now to absolute_frchain. Verify that
3979 frch_last and frag_now match on entry and exit. Initialize
3980 per-chain obstack, and under gcc, set required alignment to that
3981 needed by fragS structure.
3983 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
3985 * stabs.c (get_stab_string_offset): Only copy input string if a
3986 fresh copy is needed, not if the section already exists.

3988 usually it will match. Could be made faster still by changing the
3989 memory allocation rules.
3990 (s_xstab): Cache section name to bypass repeated string
3993 * frags.c (frag_new): Deleted register declarations.
3995 * listing.c (frag_now): Don't declare.
3997 * as.c (chunksize): New variable.
3998 (debug_memory): New variable.
3999 (main): If debug_memory is set, reduce chunksize and

4007 * Makefile.in (distclean): Remove Makefile and config.status from
4008 testsuite directory.

4010 files within it that would be generated by running tests.
4012 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
4013 frag_now_fix instead of accessing obstack info directly.
4014 * config/tc-arm.c (s_ltorg): Ditto.
4015 (md_assemble): Ditto.
4017 * config/tc-i386.c (md_assemble): Call frag_grow instead of
4020 Wed Oct 18 12:22:59 1995 Ken Raeburn <raeburn@cygnus.com>
4022 * stabs.c (aout_process_stab): Insert debug symbol into symbol
4023 chain after parsing value expression, if any, to avoid separating
4024 continued .stabs lines.
4026 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
4028 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
4029 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
4031 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
4033 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
4034 -mcom support and PPC_OPCODE_ANY for -many.
4035 (md_parse_option): Ditto.
4037 (md_begin): For duplicate instructions, print all duplicates
4040 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
4042 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
4043 common mode operation.
4044 (md_show_usage): Add -mcom to usage message.
4046 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>

4049 * expr.h (operatorT): Add O_symbol_rva.
4050 * read.c (cons_worker): Set O_symbol_rva when necessary.

4053 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>
4055 * config/tc-mips.c: Correct s_cons arguments. From Michael
4056 Joosten <joost@ori.cadlab.de>.

4060 * config/tc-ppc.c (ppc_macro): Make count unsigned.
4061 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
4062 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
4064 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
4065 make non-static. Change all users.
4066 * config/obj-coff.h (coff_n_line_nos): Declare.

4070 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
4072 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
4074 * config/obj-elf.c (obj_elf_common): Convert specified byte
4075 alignment to power of two. Set size of local bss symbol.

4079 Fri Oct 6 15:22:25 1995 Ian Lance Taylor <ian@cygnus.com>
4081 * sb.c, macro.c: Decide whether to include <string.h> or
4082 <strings.h> just as as.h does.
4084 Fri Oct 6 09:55:33 1995 Doug Evans <dje@canuck.cygnus.com>

4094 * doc/as.texinfo: Split out the NS32k family documentation,
4095 despite its being commented out for now.
4096 * doc/c-ns32k.texi: New file.
4098 * sb.c, macro.c: Include string.h.
4100 * Makefile.in (comparison): Only check *.o; we don't care if
4101 timestamps inserted by the native linker differ.
4103 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4104 if alignment stricter than 4 bytes is requested; in that case,
4105 align to a 4-byte boundary first.
4107 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
4109 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

4114 * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
4115 qualifiers and detect errors if present.
