	same name.

Tue Oct 24 14:50:38 1995  Michael Meissner  <meissner@tiktok.cygnus.com>

	* config/tc-ppc.h (TC_FORCE_RELOCATION_SECTION): Rename from
	TC_FORCE_RELOCATION, taking an additional section argument.  If
	the section of the target symbol is not the same as the current
	section, always force the relocation to be used.
	(MD_PCREL_FROM_SECTION): New macro to call md_pcrel_from_section.

	* config/tc-ppc.c (md_pcrel_from_section): Rename from the
	md_pcrel_from function, taking an additional section argument.
	Invoke TC_FORCE_RELOCATION_SECTION instead of TC_FORCE_RELOCATION.

	* write.c (TC_FORCE_RELOCATION_SECTION): Define in terms of the
	older TC_FORCE_RELOCATION if not defined.
	(MD_PCREL_FROM_SECTION): If not defined, invoke md_pcrel_from.
	(fixup_segment): Use MD_PCREL_FROM_SECTION instead of
	md_pcrel_from, and TC_FORCE_RELOCATION_SECTION instead of
	TC_FORCE_RELOCATION.
	
Mon Oct 23 16:20:04 1995  Ken Raeburn  <raeburn@cygnus.com>

	* input-scrub.c (as_where): Set name to null pointer if we don't
	have a file name.

	(as_warn_internal, as_bad_internal): Ditto.

	* input-file.c (input_file_open): If the input file can't be
	opened, consider it an error.

 	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.

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

	(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.

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

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

	* 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.

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

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

	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.

	* config/obj-vms.c (VMS_RSYM_Parse): eliminate "might be used
