Tue Mar  2 08:53:34 1993  Ken Raeburn  (raeburn@cygnus.com)

	* config/tc-m68k.c (isbyte): Accept all values from -255 to +255,
	so "~0x80" won't be rejected.

	* config/obj-elf.c: No longer include elf/reloc.h.
	(obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
	(obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
	routines.
	(obj_elf_xstab): New routine.
	(obj_elf_set_size): Call as_warn, not fprintf.  Pass desired
	argument to s_ignore.  Put "#if 0" around unused code.
	(obj_pseudo_table): Use s_ignore instead of do-nothing routines.
	Call elf_xstabs for .stabs and .xstabs operators.

	* config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".

	* write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
	present.

	* configure.in: mips-bsd configuration was missing format spec.
	Should use aout.

	* Makefile.in (Makefile): Depends on configure.in.

	* config/tc-mips.c (append_insn): Don't check for alignment of
	frag in memory; alignment of instructions in section is a separate
	matter.

	* config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
	C availability.

	* listing.h: Always provide function declarations, not macros, so
	pcc won't lose.

	md_relax_table): Use default zero initialization.
	(s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the

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

	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.
	* make-gas.com: Redone to work with new scheme.
	* 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
	  as needed.
	* 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.
	* config/ho-vms.h: define HO_VMS, not HO_VAX.

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

	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-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.

	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/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

	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.

	(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)

	characteristics have been), default to 68020.  Don't need extra
	quotes around error string.

	* read.c (potable): Revert sac's incorrect change made Jul 13.

	  -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced

	* 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.
