Tue Jan  5 08:42:16 1993  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* expr.c (operand): If character other than comma or newline is a
	logical end-of-line character, use the newline case.

	* configure.in (per-target): Look for with_bfd_assembler option.
	For now, only accept "no", until the merge is done.

Mon Jan  4 05:17:26 1993  Ken Raeburn  (raeburn@cygnus.com)

	* read.c (s_data): Always use "data_section", since it'll map to
	SEG_DATA or SEG_E1 if needed.
	(s_lcomm): Likewise with bss_section.
	(s_fill): Use memset, not bzero.

Thu Dec 31 04:29:27 1992  Ken Raeburn  (raeburn@kr-pc.cygnus.com)

	* read.c: Deleted some code under "#ifdef DONTDEF" that was for
	handling GDB symbol table data.

	otherwise, use seg_name array.
	(seg_name): Declare only if not BFD_ASSEMBLER.
	(section_alignment): Declare only if not BFD_ASSEMBLER.
	(big_section, reg_section, pass1_section, diff_section,
	absent_section, text_section, data_section, bss_section): If
	BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
	mapping to segT enum values.
	(tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
	if these are used or defined, if BFD_ASSEMBLER.
	(subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
	subseg_new split into two functions.
	(SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.

	* as.h (volatile): Don't define if already defined.
	(had_errors, had_warnings): Provide prototypes for ANSI C even if
	NO_STDARG.
	(as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
	declare with format attribute for -Wformat checking.

Wed Dec 30 10:18:57 1992  Ian Lance Taylor  (ian@cygnus.com)

	* app.c, config/tc-*.c: Don't include read.h, since it is already
	included by as.h.

	* These are based on patches from Minh Tran-le
	<mtranle@paris.intellicorp.com>.
	* configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
	obj_format coffbfd and gas_target i386coff for target.
	(i[34]86-*-isc*): New host (uses sysv).
	* config/i386aix.mt: Removed (no longer used).
	* config/mh-i386aix (RANLIB): Use true rather than /bin/true.
	(MINUS_G): Removed.
	(LDFLAGS): Added, defined as -shlib.
	* config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
	* config/te-sco386.h (LOCAL_LABEL): Don't define.
	(DOT_LABEL_PREFIX): Define.
	* expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
	name rather than L0\001.
	* read.c (s_lcomm): Make a frag in SEG_BSS rather than using
	local_bss_counter.
	* symbols.c, symbols.h (local_bss_counter): Removed.
	* write.c (write_object_file): bss no longer uses
	local_bss_counter.  Pass correct data and bss size to
	VMS_write_object_file.
	* config/obj-vms.c (VMS_write_object_file): Accept bss size as
	argument, rather than using local_bss_counter.
	* config/tc-m88k.c (s_bss): Don't use local_bss_counter.
	* config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
	* config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
	(size_section): Restored sanity check.
	(do_relocs_for): Base section address on s_paddr rather than
	computing it.  Adjust a29k R_IHIHALF special case to account for
	section paddr (used to require paddr to be zero).  If there are no
	reclos, set s_relptr to 0.  Set relocation size in object_headers.
	(fill_section): Always set s_vaddr here, removing
	ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
	NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
	Set STYP_INFO for .comment.
	(coff_header_append): Use object headers and H_{SET,GET}_* macros.
	Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

	H_{SET,GET}_* macros.
	(do_linenos_for): Set lineno size in object_headers.
	(write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
	set s_vaddr here.  If string_byte_count remains 4, set it back to
	0, and only write strings out if there are some.  Call
	fill_section before do_relocs_for and do_linenos_for.
	(obj_coff_section): Handle optional quoted second argument giving
	section characteristics.
	(obj_coff_bss): Added to handle .bss.
	(obj_coff_ident): Added to handle .ident (puts string in .comment
	section).
	(obj_coff_lcomm): Put common symbols in .bss, not .data.
	(fixup_mdeps): Change to segment.  Call frag_wane after
	md_convert_frag.
	(fixup_segment): Explicitly check S_IS_COMMON before making 386
	adjustment (already happened only for common symbols, but this is
	clearer).
	* config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
	* config/tc-i386.c (s_bss): Don't use if I386COFF.
	(md_pseudo_table): Ignore .optim and .noopt.
	(tc_coff_sizemachdep): New function.

	(do_scrub_next_char): For \", return " not '.
	(symbol_chars): Now const.

	* expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
	and "0b".  If LOCAL_LABELS_DOLLAR, check for "0$".

	* config/obj-coff.h: Don't use #elif.

	* config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
	have it.  (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)

Wed Dec 16 12:12:33 1992  Ian Lance Taylor  (ian@cygnus.com)

	* write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

	* config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
	using ZERO_BASED_SEGMENTS.
	(fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
	never set segment address for SEG_E2 (.bss) and don't write out
	SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
	(obj_coff_endef): Don't merge labels or symbols awaiting forward
	definitions, and don't merge tags with non-tags.  Check for .bf
	rather than just checking whether the second character is b and
	the third character is f.
	(obj_coff_val): gcc can generate values which we don't handle
	correctly; discard information for now, since it only affects the
	debugging information.
	(tag_find_or_name): Don't insert tags in the symbol table.
	(yank_symbols): Don't merge labels.
	(write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
	already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
	set segment address if ZERO_BASED_SEGMENTS.
	(obj_coff_section): Accept and ignore a trailing quoted string, as
	used in AT&T i386 syntax.

	local labels to start with a .) and set REGISTER_PREFIX to %.
	tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)

	ignore.

Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)

	* obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
	sections starting from zero, rather than making them consecutive.
	This makes subsequent reloc calculations easier, esp if the object
	format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
	allocate lcomm in .data rather than in .bss.  It seems that some
	tools can't cope with a non-zero sized bss before linkage.
 
Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* tc-m68k.c: Replace "enum m68k_architecture" with "int"

	$(tooldir)/bin.

Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)

	* Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
	.word is < -32768 or > 32767.  The -J flag causes the error to be
	ignored.  This is to catch over-sized switches generated by gcc on
	systems which don't support the broken .word hack.
	as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
	write.c (fixup_segment): check for signed .word overflow if
	WARN_SIGNED_OVERFLOW_WORD.

Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* expr.c: If an expression is single comma, then return with
	SEG_ABSENT rather than an error - since the sparc front end does
	really strange things with things like fbge,a 

	* as.h: include bfd.h if using many sections
	* expr.c: LOCAL_LABELS_FB had been changed to lower case - so
	local labels didn't work.

	symbol there.
	* write.c, write.h: call fix_new with the right number of args on
	the H8.
	* config/tc-h8300.[ch] : fix bugs reported by HMSI, and make

	* app.c: MRI compatibility - allow single quote to start a string.
	* as.c: fix typo recently introduced.
	* as.h : Don't include aout/reloc.h - it's not right for COFF!
	* expr.c: Much rewriting, to accomodate MRI syntax for
	expressions. Also easier to read now.
	* listing.c: Put back defuns
	* read.c: modified to accept MRI syntax, put back listing pseudo
	ops so that an assembler built with NO_LISTING ignores list ops
	rather than pukes.
	* write.c, write.h: fixs - only keep a reloc type in a fix if the target
	machine is a SPARC or a 29K.
	* config/obj-aout.c: added s_sect pseudo op
	* config/obj-coffbfd.c: lints, set the filehdr flags right and
	fill in the timestamp.
	* config/obj-coffbfd.h: Since we don't include aout/reloc.h
	anymore, define all the relocs which the tc-<x> bit will use so we
	can translate from them to the coff types.
	* config/tc-a29k.c: reloc_type isn't ane enum any more
	* config/tc-m68k.c: Added NO_RELOC definition.

Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)

	* Makefile.in: put header files before C source for TAGS; remove
	  references to non-existent syscalls.h.

	* read.c, write.c subsegs.c: back out the .bss changes.

	* obj-aout.c: do not include stab.gnu.h if NO_LISTING.

	* tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.

	* a.out.h: removed.

Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)

	* symbols.c (local_label_name): symbols now start with ^A.

	* read.c, subsegs.c, write.c obj-coff.c: added handling of
	  `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
	  generate these sections.  .align: will use NOP_OPCODE or 0
	  for padding. This is just for being nice to the
	  disassembler.

	* expr.c (operand): changed to generate local label "\001L0"
	  starting with a ^A so that it is recognized as a local label.

	* as.c (perform_an_assembly_pass): zero bss_fix_root, too.

	* tc-i386.c: tc-i386.c: added handling of the following opcodes:
	  i/o opcodes - inb, inw, outb and outw.  string manipulation with
	  att syntax - scmp, slod, smov, ssca, ssto.

	* obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
	  to just after .file .

	  In obj_crawl_symbol_chain() where it tries to put the external
	  symbols apart, with the condition:
	    (!S_IS_DEFINED(symbolP) &&
	     !S_IS_DEBUG(symbolP) &&
	     !SF_GET_STATICS(symbolP))
	  it was moving too many symbols out. So I switch it back to the
	  condition:
	    (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))

	  In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
	  so that we don't use the F_RELFLG which make the linker complain
	  that somebody has stripped the relocation info.

	  Also, the AIX ld program require that the relocation table
	  is sorted by r_vaddr like the standard ATT assembler does.

	  [he also changed the sizeof(struct ...)'s into the coff
	  style FOOSZ macros.  I'm not sure this is right, but I can't
	  remember why.  xoxorich.]

Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)

	* Makefile.in, configure.in, doc: use the doc.  Build it, install

	* read.c: white space and comments only.

	* configure.in: use the new atof-ns32.c for ns32k.

	* write.c: comment change only.

	* tc-m88k.[hc]: pulled in from hack's unfinished work.  These
	  aren't yet integrated.

	* tc-i860.[hc]: blew off the dust.  Something must still be done
	  about conflicting relocation types.

	* tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
	  real thing.

	* tc-i960.c, tc-sparc.c: white space and comments only.

	* tc-a29k.h: delete duplicate macro definition.

	* new file atof-ns32k.c copied from hack's last unreleased gas.

Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)

	* config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
	  rather than abort.
				       
	* nearly everything.  flush ChangeLog, package as gas-1.92.1.
	  ChangeLog's prior to this are sketchy at best.  I have logs.
	  They just aren't ChangeLogs.
