1942 * frags.h (frags): Declaration deleted.
1943 * subsegs.h (struct frchain): Add new field frch_frag_now.
1944 * subsegs.c (frchains, dummy_frag, absolute_frchain): New static
1946 (subsegs_begin): Initialize frchains obstack. Under gcc, don't
1947 give it any stricter alignment than frchainS structures need. Do
1948 not initialize frags obstack. Set frag_now to point to
1949 dummy_obstack. Initialize absolute_frchain.
1950 (subseg_set_rest): Save and restore frag_now in frch_frag_now
1951 field of frchainS. Don't create new frags on section switch, and
1952 use frag_alloc when creating a new frag chain. For absolute
1953 section, set frchain_now to absolute_frchain. Verify that
1954 frch_last and frag_now match on entry and exit. Initialize
1955 per-chain obstack, and under gcc, set required alignment to that
1956 needed by fragS structure.
1958 * write.c (chain_frchains_together_1): Verify fr_type is nonzero.
1960 * stabs.c (get_stab_string_offset): Only copy input string if a
1961 fresh copy is needed, not if the section already exists.

1963 usually it will match. Could be made faster still by changing the
1964 memory allocation rules.
1965 (s_xstab): Cache section name to bypass repeated string
1968 * frags.c (frag_new): Deleted register declarations.
1970 * listing.c (frag_now): Don't declare.
1972 * as.c (chunksize): New variable.

1977 * read.c (read_begin): Use it.
1979 * config/tc-alpha.c (md_shortopts): Include 'g'.
1980 (md_parse_option): Ignore it.
1982 * Makefile.in (distclean): Remove Makefile and config.status from
1983 testsuite directory.

1985 files within it that would be generated by running tests.
1987 * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1988 frag_now_fix instead of accessing obstack info directly.

2003 * config/tc-mips.c (mips_elf_pseudo_table): Remove.
2004 (mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.
2006 Mon Oct 16 07:07:37 1995 Michael Meissner <meissner@wogglebug.tiac.net>
2008 * config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
2009 -mcom support and PPC_OPCODE_ANY for -many.
2010 (md_parse_option): Ditto.
2012 (md_begin): For duplicate instructions, print all duplicates
2015 Sun Oct 15 22:06:14 1995 Michael Meissner <meissner@cygnus.com>
2017 * config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
2018 common mode operation.
2019 (md_show_usage): Add -mcom to usage message.

2023 * expr.c (op_rank): Add O_symbol_rva.
2024 * expr.h (operatorT): Add O_symbol_rva.
2025 * read.c (cons_worker): Set O_symbol_rva when necessary.

2036 (ppc_biei): Set segment to now_seg and value to coff_n_line_nos.
2037 (ppc_frob_symbol): Handle C_BINCL and C_EINCL symbols by setting
2039 * config/obj-coff.c (coff_n_line_nos): Rename from n_line_nos, and
2040 make non-static. Change all users.
2041 * config/obj-coff.h (coff_n_line_nos): Declare.
2043 Fri Oct 6 16:24:27 1995 Ken Raeburn <raeburn@cygnus.com>
2045 Mon Sep 25 22:49:32 1995 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
2047 * configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.
2049 * config/obj-elf.c (obj_elf_common): Convert specified byte
2050 alignment to power of two. Set size of local bss symbol.

2071 * doc/c-ns32k.texi: New file.
2073 * sb.c, macro.c: Include string.h.
2075 * Makefile.in (comparison): Only check *.o; we don't care if
2076 timestamps inserted by the native linker differ.
2078 * config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
2079 if alignment stricter than 4 bytes is requested; in that case,
2080 align to a 4-byte boundary first.
2082 Thu Sep 28 19:35:27 1995 Pat Rankin <rankin@eql.caltech.edu>
2084 * config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used

2089 * config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
2090 qualifiers and detect errors if present.
