binutils-gdb/gas/ChangeLog

Mon Oct 23 11:15:44 1995  James G. Smith  <jsmith@pasanda.cygnus.co.uk>

	* config/tc-mips.c: Added mips_4100 control, and support for
 	accepting the 4100 as a MIPS architecture variant (md_begin,
 	macro_build, mips_ip, md_parse_option). Adding suitable
 	command-line OPTIONs, and updating the help text (md_show_usage).
	
Wed Oct 18 13:20:32 1995  Ken Raeburn  <raeburn@cygnus.com>

	* subsegs.c (subseg_begin): Only set absolute_frchain.fix_* when
	BFD_ASSEMBLER is defined.

	* Use one active frag and one obstack per frag chain:
	* frags.c (frags): Variable deleted.
	(frag_alloc): New function.
	(frag_grow, frag_more, frag_variant, frag_now_fix,
	frag_append_1_char): Refer to frchain_now->frch_obstack instead of
	frags variable.
	(frag_new): Ditto.  Verify that frch_last and frag_now match on
	entry and exit, and that old frag_now has non-zero type.  Replace
	"know" uses with "assert".  Use frag_alloc instead of mucking with
	obstack alignment.
	* frags.h (frags): Declaration deleted.
	* subsegs.h (struct frchain): Add new field frch_frag_now.
	* subsegs.c (frchains, dummy_frag, absolute_frchain): New static
	variables.
	(subsegs_begin): Initialize frchains obstack.  Under gcc, don't
	give it any stricter alignment than frchainS structures need.  Do
	not initialize frags obstack.  Set frag_now to point to
	dummy_obstack.  Initialize absolute_frchain.
	(subseg_set_rest): Save and restore frag_now in frch_frag_now
	field of frchainS.  Don't create new frags on section switch, and
	use frag_alloc when creating a new frag chain.  For absolute
	section, set frchain_now to absolute_frchain.  Verify that
	frch_last and frag_now match on entry and exit.  Initialize
	per-chain obstack, and under gcc, set required alignment to that
	needed by fragS structure.

	* write.c (chain_frchains_together_1): Verify fr_type is nonzero.

	* stabs.c (get_stab_string_offset): Only copy input string if a
	fresh copy is needed, not if the section already exists.
	(s_stab_generic): Cache stab section name to bypass lookups, since
	usually it will match.  Could be made faster still by changing the
	memory allocation rules.
	(s_xstab): Cache section name to bypass repeated string
	allocation.

	* frags.c (frag_new): Deleted register declarations.

	* listing.c (frag_now): Don't declare.

	* as.c (chunksize): New variable.
	(debug_memory): New variable.
	(main): If debug_memory is set, reduce chunksize and
	_bfd_chunksize.
	* as.h (chunksize): Declare it.
	* read.c (read_begin): Use it.

	* config/tc-alpha.c (md_shortopts): Include 'g'.
	(md_parse_option): Ignore it.

	* Makefile.in (distclean): Remove Makefile and config.status from
	testsuite directory.
	(clean-here): Don't delete testsuite.  Instead, delete only the
	files within it that would be generated by running tests.

	* config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
	frag_now_fix instead of accessing obstack info directly.
	* config/tc-arm.c (s_ltorg): Ditto.
	(md_assemble): Ditto.

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

Wed Oct 18 12:22:59 1995  Ken Raeburn  <raeburn@cygnus.com>

	* stabs.c (aout_process_stab): Insert debug symbol into symbol
	chain after parsing value expression, if any, to avoid separating
	continued .stabs lines.

Mon Oct 16 10:56:41 1995  Ian Lance Taylor  <ian@cygnus.com>

	* config/tc-mips.c (mips_elf_pseudo_table): Remove.
	(mips_pop_insert): Don't call pop_insert on mips_elf_pseudo_table.

Mon Oct 16 07:07:37 1995  Michael Meissner  <meissner@wogglebug.tiac.net>

	* config/tc-ppc.c (md_begin): Use new flags PPC_OPCODE_COMMON for
	-mcom support and PPC_OPCODE_ANY for -many.
	(md_parse_option): Ditto.
	(ppc_arch): Ditto.
	(md_begin): For duplicate instructions, print all duplicates
	before aborting.

Sun Oct 15 22:06:14 1995  Michael Meissner  <meissner@cygnus.com>

	* config/tc-ppc.c (md_parse_option): Support for -mcom to turn on
	common mode operation.
	(md_show_usage): Add -mcom to usage message.

Fri Oct 13 13:32:45 1995  steve chamberlain  <sac@slash.cygnus.com>

	* expr.c (op_rank): Add O_symbol_rva.
	* expr.h (operatorT): Add O_symbol_rva.
	* read.c (cons_worker): Set O_symbol_rva when necessary.
	* write.c (fix_new_exp): Understand O_symbol_rva.

Tue Oct 10 11:34:14 1995  Ian Lance Taylor  <ian@cygnus.com>

	* config/tc-mips.c: Correct s_cons arguments.  From Michael
	Joosten <joost@ori.cadlab.de>.

Mon Oct  9 19:59:53 1995  Ian Lance Taylor  <ian@cygnus.com>

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

Fri Oct  6 16:24:27 1995  Ken Raeburn  <raeburn@cygnus.com>

	Mon Sep 25 22:49:32 1995  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* configure.in (AC_ARG_WITH(bfd-assembler)): Fix help message.

	* config/obj-elf.c (obj_elf_common): Convert specified byte
	alignment to power of two.  Set size of local bss symbol.

	* config/tc-m68k.c (tc_gen_reloc): Fix typo in variable name.

Fri Oct  6 15:22:25 1995  Ian Lance Taylor  <ian@cygnus.com>

	* sb.c, macro.c: Decide whether to include <string.h> or
	<strings.h> just as as.h does.

Fri Oct  6 09:55:33 1995  Doug Evans  <dje@canuck.cygnus.com>

	* Makefile.in (site.exp): Fix setting of $srcdir.

	* config/tc-arm.c (md_atof): Fix little-endian output.
	* config/tc-arm.h (ARM_BI_ENDIAN): Move definition so defined for
	all coff targets.

Thu Oct  5 20:17:30 1995  Ken Raeburn  <raeburn@cygnus.com>

	* doc/as.texinfo: Split out the NS32k family documentation,
	despite its being commented out for now.
	* doc/c-ns32k.texi: New file.

	* sb.c, macro.c: Include string.h.

	* Makefile.in (comparison): Only check *.o; we don't care if
	timestamps inserted by the native linker differ.

	* config/tc-alpha.c (alpha_align): Only fill with a no-op pattern
	if alignment stricter than 4 bytes is requested; in that case,
	align to a 4-byte boundary first.

	Thu Sep 28 19:35:27 1995  Pat Rankin  <rankin@eql.caltech.edu>

	* config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used
	uninitialized" warning for `Max_Source_Offset'.

	* config/tc-ppc.c (parse_toc_entry): New function to parse [toc]
	qualifiers and detect errors if present.
	(md_assemble): Add call to parse_toc_entry. Also added some support
	for the [tocv] qualifier.
	(ppc_pe_tocd): New function to support data in the toc section.

	* config/tc-m68k.c (isbyte): Accept all values from -65536 to
	+65535,	so ~VAL will not be rejected.

	* cond.c (s_endif): Call demand_empty_rest_of_line.  In MRI mode,
	skip characters after the pseudo-op.
	(s_else): Likewise.
	* read.c (get_line_sb): Don't look past buffer_limit.
