1944 frag_append_1_char): Refer to frchain_now->frch_obstack instead of
1946 (frag_new): Ditto. Verify that frch_last and frag_now match on
1947 entry and exit, and that old frag_now has non-zero type. Replace
1948 "know" uses with "assert". Use frag_alloc instead of mucking with
1950 * frags.h (frags): Declaration deleted.
1951 * subsegs.h (struct frchain): Add new field frch_frag_now.
1952 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
1954 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
1955 give it any stricter alignment than frchainS structures need. Do
1956 not initialize frags obstack. Set frag_now to point to
1957 dummy_obstack. Initialize absolute_frchain.
1958 (subseg_set_rest): Save and restore frag_now in frch_frag_now
1959 field of frchainS. Don't create new frags on section switch, and
1960 use frag_alloc when creating a new frag chain. For absolute
1961 section, set frchain_now to absolute_frchain. Verify that
1962 frch_last and frag_now match on entry and exit. Initialize
1963 per-chain obstack, and under gcc, set required alignment to that
1964 needed by fragS structure.
1966 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.

1971 usually it will match. Could be made faster still by changing the
1972 memory allocation rules.
1973 (s_xstab): Cache section name to bypass repeated string
1976 * frags.c (frag_new): Deleted register declarations.
1978 * listing.c (frag_now): Don't declare.
1980 * as.c (chunksize): New variable.
1981 (debug_memory): New variable.

1990 * Makefile.in (distclean): Remove Makefile and config.status from
1991 testsuite directory.

1993 files within it that would be generated by running tests.
1995 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1996 frag_now_fix instead of accessing obstack info directly.

1998 (md_assemble): Ditto.
2000 * config/tc-i386.c (md_assemble): Call frag_grow instead of

2005 * stabs.c (aout_process_stab): Insert debug symbol into symbol
2006 chain after parsing value expression, if any, to avoid separating
2007 continued .stabs lines.
2009 Mon Oct 16 10:56:41 1995 Ian Lance Taylor <ian@cygnus.com>
2011 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
2012 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
2014 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
2016 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
2017 -mcom support and PPC_OPCODE_ANY for -many.
2018 (md_parse_option): Ditto.
2020 (md_begin): For duplicate instructions, print all duplicates
2023 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
2025 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
2026 common mode operation.
2027 (md_show_usage): Add -mcom to usage message.
2029 Fri Oct 13 13:32:45 1995 steve chamberlain <sac@slash.cygnus.com>

2032 * expr.h (operatorT): Add O_symbol_rva.
2033 * read.c (cons_worker): Set O_symbol_rva when necessary.
2034 * write.c (fix_new_exp): Understand O_symbol_rva.
2036 Tue Oct 10 11:34:14 1995 Ian Lance Taylor <ian@cygnus.com>

2043 * config/tc-ppc.c (ppc_macro): Make count unsigned.
2044 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
2045 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
2047 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
2048 make non-static. Change all users.
2049 * config/obj-coff.h (coff_n_line_nos): Declare.

2053 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
2055 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
2057 * config/obj-elf.c (obj_elf_common): Convert specified byte

2079 * doc/c-ns32k.texi: New file.
2081 * sb.c, macro.c: Include string.h.
2083 * Makefile.in (comparison): Only check *.o; we don't care if
2084 timestamps inserted by the native linker differ.
2086 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
2087 if alignment stricter than 4 bytes is requested; in that case,
2088 align to a 4-byte boundary first.
2090 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
2092 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used
