Wed Mar 17 16:44:06 1993  Ian Lance Taylor  (ian@cygnus.com)

	* app.c (do_scrub_next_char): Added new state, 9, to avoid

	md_relax_table): Use default zero initialization.
	(s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
	latter, instead of selecting with preprocessor conditionals.

Thu Jan  7 08:58:21 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* expr.c (operand): If character other than comma or newline is a
	logical end-of-line character, use the newline case.
	From Eric Youngdale:
	(operand): Set X_add_number field for floating-point numbers.
	(operand): Treat zero byte as end-of-operand.

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

	Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
	* as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
	  config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
	* read.c: Finish conversion to S_* macros in the VMS only
	  parts of the program. Add "const" modifier to hex_value.
	* as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
	  "ifdef OBJ_VMS".
	* expr.c: Add "const" modifier to hex_value.
	* symbols.c: Finish conversion to S_* macros in the VMS only
	  parts of the program.  Add "const" modifier to
	  md_[long,short]_jump_size. Remove declaration of const_flag
	  (which will be declared in obj-vms.h).
	* write.c: Add "const" modifier to md_[long,short]_jump_size.
	  Fix arguments to VMS_write_object_file.
	* config-gas.com: New file.  Script for VMS systems to set up the
	  configuration to build gas for VMS, and create config.status.

	* obj-vms.c: Patch to fix bug where we were not correctly parsing the
	  stabs directives.
	* obj-vms.c:  Define macros COPY_LONG and COPY_SHORT which
	  will swap bytes if needed on a big endian system.  Use throughout

	* obj-vms.c (obj_aout_stab):  Add code to generate listing file.
	* obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
	  types of malformed stabs.  Change parsing algorithm so that we are
	  more certain of having all of the information that we need on hand.
	* obj-vms.c (final_forward_reference):  New function, used to help
	  resolve the data types of as many struct elements as possible
	  when some part of the struct is not fully defined by the compiler.
	* obj-vms.c (VMS_LSYM_Parse):  Correctly handle case of continuation
	  stabs directives.
	* obj-vms.c (VMS_write_object_file): Define all vtable psects
	  as symbols as well in the object file.  Look for external functions
	  that start with "__vt.", and turn them into variables, since the
	  g++ compiler is incapable of doing this.
	* tc-vax.c: Add '1' option for backward compatibility with older GCC
	  versions.
	* bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
	* input-scrub.c (as_where): Fix bug where as would crash if we did not
	  have the name of the source file yet.

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

	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.

	* 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

	(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

	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/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)

	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

	* Makefile.in (strerror.o): Add rule so that broken Sun make can
	work in subdirs.

Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)

	* read.c, obj-coffbfd.c : fix h8300 specific bit rot

	* expr.c (operand): if can't work out what sort of operand it is,
	then look through FLT_CHARS for a hint.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)

	* Makefile.in, configure.in: removed traces of namesubdir,
	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
	  copyrights to '92, changed some from Cygnus to FSF.

	* doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
	  copyrights to '92, changed some from Cygnus to FSF.

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.
	* listing.c (list_symbol_table): don't core dump when there's no
	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
	errors nices

Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* 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
	  it, clean it, etc.

Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)

	* 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.
