3942 (frag_grow, frag_more, frag_variant, frag_now_fix,
3943 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
3945 (frag_new): Ditto. Verify that frch_last and frag_now match on
3946 entry and exit, and that old frag_now has non-zero type. Replace
3947 "know" uses with "assert". Use frag_alloc instead of mucking with
3949 * frags.h (frags): Declaration deleted.
3950 * subsegs.h (struct frchain): Add new field frch_frag_now.
3951 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
3953 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
3954 give it any stricter alignment than frchainS structures need. Do
3955 not initialize frags obstack. Set frag_now to point to
3956 dummy_obstack. Initialize absolute_frchain.
3957 (subseg_set_rest): Save and restore frag_now in frch_frag_now
3958 field of frchainS. Don't create new frags on section switch, and
3959 use frag_alloc when creating a new frag chain. For absolute
3960 section, set frchain_now to absolute_frchain. Verify that
3961 frch_last and frag_now match on entry and exit. Initialize
3962 per-chain obstack, and under gcc, set required alignment to that
3963 needed by fragS structure.
3965 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
3967 * stabs.c (get_stab_string_offset): Only copy input string if a
3968 fresh copy is needed, not if the section already exists.

3970 usually it will match. Could be made faster still by changing the
3971 memory allocation rules.
3972 (s_xstab): Cache section name to bypass repeated string
3975 * frags.c (frag_new): Deleted register declarations.
3977 * listing.c (frag_now): Don't declare.
3979 * as.c (chunksize): New variable.
3980 (debug_memory): New variable.

3986 * config/tc-alpha.c (md_shortopts): Include 'g'.
3987 (md_parse_option): Ignore it.
3989 * Makefile.in (distclean): Remove Makefile and config.status from
3990 testsuite directory.

3992 files within it that would be generated by running tests.
3994 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
3995 frag_now_fix instead of accessing obstack info directly.

3997 (md_assemble): Ditto.
3999 * config/tc-i386.c (md_assemble): Call frag_grow instead of

4004 * stabs.c (aout_process_stab): Insert debug symbol into symbol
4005 chain after parsing value expression, if any, to avoid separating
4006 continued .stabs lines.
4008 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
4010 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
4011 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
4013 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
4015 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
4016 -mcom support and PPC_OPCODE_ANY for -many.
4017 (md_parse_option): Ditto.
4019 (md_begin): For duplicate instructions, print all duplicates
4022 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
4024 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
4025 common mode operation.
4026 (md_show_usage): Add -mcom to usage message.
4028 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>
4030 * expr.c (op_rank): Add O_symbol_rva.
4031 * expr.h (operatorT): Add O_symbol_rva.
4032 * read.c (cons_worker): Set O_symbol_rva when necessary.
4033 * write.c (fix_new_exp): Understand O_symbol_rva.
4035 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>
4037 * config/tc-mips.c: Correct s_cons arguments. From Michael
4038 Joosten <joost@ori.cadlab.de>.
4040 Mon Oct 9 19:59:53 1995 Ian Lance Taylor <ian@cygnus.com>
4042 * config/tc-ppc.c (ppc_macro): Make count unsigned.
4043 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
4044 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
4046 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
4047 make non-static. Change all users.
4048 * config/obj-coff.h (coff_n_line_nos): Declare.

4052 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
4054 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
4056 * config/obj-elf.c (obj_elf_common): Convert specified byte
4057 alignment to power of two. Set size of local bss symbol.

4061 Fri Oct 6 15:22:25 1995 Ian Lance Taylor <ian@cygnus.com>
4063 * sb.c, macro.c: Decide whether to include <string.h> or
4064 <strings.h> just as as.h does.
4066 Fri Oct 6 09:55:33 1995 Doug Evans <dje@canuck.cygnus.com>
4068 * Makefile.in (site.exp): Fix setting of $srcdir.

4078 * doc/c-ns32k.texi: New file.
4080 * sb.c, macro.c: Include string.h.
4082 * Makefile.in (comparison): Only check *.o; we don't care if
4083 timestamps inserted by the native linker differ.
4085 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
4086 if alignment stricter than 4 bytes is requested; in that case,
4087 align to a 4-byte boundary first.
4089 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
4091 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

4097 qualifiers and detect errors if present.
