	* expr.c (expand_builtin, case BUILT_IN_NEXT_ARG): Allow in varargs
	function.

	* config/lynx.h: Rewritten to work with GNU as and ld, using COFF
	format.
	* config/i386/lynx.h: Include i386/gas.h instead of i386/gstabs.h.

	to disable building libgcc1

Thu Oct 14 13:29:12 1993  Doug Evans  (dje@canuck.cygnus.com)

	* Makefile.in (RUNTEST_CFLAGS): Add -Iinclude for just build gcc.

	* h8300/t-h8300 (CMPtype) gcc assumes library calls have word_mode
	results.

	* expr.c (expand_expr, case OFFSET_REF): remove CYGNUS LOCAL
	commenting out of this case. g++ now uses CP_OFFSET_REF.

	* fixproto:  Re-write.  We now assume that there are two
	source directories (source_dir_all and source_dir_std).  These
	are handled differently.  All files in source_dir_all (normally
	./include) are processed, but in source_dir_std (normally
	/usr/include) we only process the standard ANSI/Posix ones where
	we might be able to add missing prototypes.
	* scan-decls.c (scan_decls):  Rewrote from being a program whose
	output is piped to patch-header, to a subroutine called by
	patch-header.  This should be somewhat more efficient.
	* Makefile.in (scan-decls):  Removed rule to make program.
	* patch-header.c (recognized_macro, recognized_extern,
	recognized_function):  New functins, with logic moved out from
	read_scan_file, so they can be called by scan_decls.
	* patch-header (main):  Read the original header file into a
	buffer (rather than reading it with stdio).  This should be more
	efficient, partly because we can re-write it in place.
	(inf_skip_spaces, inf_read_upto, inf_scan_ident):  New functions,
	based on skip_spaces, read_upto, and scan_ident in scan.c, but
	these read from the in-memory buffer mentioned above.
	* scan-types.sh:  Don't check for sigset_t, since it can be a
	struct, whose name cannot be simplify replaced by its definition.
	* Makefile.in (deduced.h):  Don't pass -nostdinc.

Tue Oct 12 17:58:43 1993  david d `zoo' zuhn  (zoo@rtl.cygnus.com)

	* configure: make inhibit_libc dependent only on cross and not on
	  newlib's presence.

	to distinguish these from other types.

	config/t-z8k: Don't set INSTALL_TARGET.

Thu Jan 14 10:23:08 1993  Ian Lance Taylor  (ian@cygnus.com)

	* configure.in: Don't make a link for float.h.  Instead, change
	FLOAT_H in Makefile.in.

	* Makefile.in (gcc.o): Pass TOOLDIR_BASE_PREFIX as $(unlibsubdir) so
	that installed directory can be moved.
	(cccp.o, stamp-proto): Pass GPLUSPLUS_INCLUDE_DIR as
	$(tooldir)/g++-include for compatibility with Cygnus libg++.

Thu Jan  7 16:11:09 1993  Steve Chamberlain  (sac@thepub.cygnus.com)

	* optabs.c (emit_float_lib_cmp): if INTmode is defined use that
	rather than SImode as the type of a fp compare function.

Wed Jan  6 09:05:47 1993  Fred Fish  (fnf@cygnus.com)

	* Makefile.in (includedir):  Default to $(prefix)/include so
	null expansions don't cause mkdirs to be issued with no args.

Mon Dec 28 10:17:32 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68*-none.h (CC1_SPEC): if -m68000 and not -m68881, pass
	-msoft-float.

	_umulsi3 to LIB1ASMFUNCS.

Tue Dec 22 17:25:07 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* configure.in: use collect2 for m68k-coff target, even though
	sections would work

Mon Dec 21 18:32:56 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* libgcc2.c (L_new_handler): don't include <stdio.h> if

	* config/fp-bit.c: use attribute(mode) trick to make it always
	use the right size int for DI SI and HI modes.

Tue Nov 10 10:22:48 1992  Ian Lance Taylor  (ian@cygnus.com)

	config/lb1sf68.asm: use __USER_LABEL_PREFIX and
	__REGISTER_PREFIX__ rather than __NO_UNDERSCORES__.

Tue Nov 10 09:18:57 1992  Mark Eichin  (eichin at cygnus.com)

	* config/xm-go32.h: don't include stddef.h, since it doesn't exist
	for cross and isn't needed -- xm-go32.h can now be included on the
	target via tconfig.h.

Thu Nov  5 17:53:32 1992  Brendan Kehoe  (brendan@cygnus.com)

	* Makefile.in (install-fixincludes): Use `if..else true; fi' when
	installing limits.h.

Fri Oct 30 22:04:59 1992  Ian Lance Taylor  (ian@cygnus.com)

	* Makefile.in: move p3 Makefile.in changes into devo.

	i960-intel-nindy: new target.

	* Merged in changes from p3 to Cygnus local files:

	config/lb1sf68.asm: new file (libgcc1 for 68000).
	config/lb1spc.asm: new file (libgcc1 for sparc).  Unused?
	config/lb1spl.asm: new file (libgcc1 for sparclite).

Thu Oct  8 14:39:43 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)

	* Makefile.in (stamp-proto): Create the stamp file after creating
	the object files, not before.

Mon Oct  5 10:57:15 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)

	* config/t-i386bsd: new file. i386 bsd with bit-float support.

	* config/t-vxworks960: added bit-float support, and force soft-float
	for libgcc2 (from p3)

	* config/fp-bit.c: added bit-float support (from p3). Emulations of
	all of the IEEE floating point routines called by gcc, with optional
	name changes for US_SOFTWARE_GOFAST. Passes Kahan's paranoia test.

	* config/t-sparclite.c: support for sparclite processor - has no
	fpu, so uses bit-float support or US Software "goFast" library.

Fri Sep 25 18:27:59 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68k-coff.h: New file.  Start local labels with . and
	register names with % to avoid conflicts with symbol names (which
	don't start with an underscore for COFF).
	config/m680?0-coff.h, config/m683?2-coff.h: include m68k-coff.h.

Mon Sep 21 15:52:18 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68k.h: a 68030 does not execute 68881 instructions, so
	-m68030 should not imply -m68881.

Wed Sep 16 11:18:49 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68*-coff.h: COFF symbols don't start with an underscore.
	Output .file at start of assembler code.

Tue Sep 15 15:57:30 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68*-none.h: changed mno68851 to mno-68851 in ASM_SPEC.

	* config/m68k.h: added 68851 and no68851 to TARGET_SWITCHES.

	(install-cross-tools): install symlinks to $(tooldir)/bin for
	programs and $(tooldir)/lib for libraries and crt0.o, and symlink to
	g++-include and sys-include to include.  If not using collect2,
	install symlink for ld.
	(install-common): added dependency on install-cross-tools, rather
	than redoing it as was done before.
	(install-libgcc): install in $(libsubdir) rather than $(tooldir).

Mon Sep 14 22:46:41 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

        * configure.in: don't use sparc-aout.h for sun4 native, just use
        sparc.h.  sparc-aout.h is used for bare target systems

Fri Sep 11 14:58:20 1992  Mark Eichin  (eichin at tweedledumber.cygnus.com)

	* Makefile.in (libgcc1): mv for directories doesn't do the same
	thing as mv for files. Since we need to keep libgcc1 "out of date"
	until replacing it with the new one, we move it out of the way
	before deleting it (if we simply deleted it and the rm -rf were
	interrupted, libgcc1 might become "up to date" and a second make
	would not cause the build to repeat.) 
	(libgcc2): same.
	(mostlyclean): delete dellibgcc* as well.

Thu Sep 10 07:47:31 1992  Ian Lance Taylor  (ian@cygnus.com)

	* configure.in, config/t-adobe, config/lb1sun3.asm: added support

Wed Sep  9 13:50:42 1992  Ian Lance Taylor  (ian@cygnus.com)

	* Makefile.in (install-man, install-dir): don't create mandir and
	man1dir unless doing make ``install-man''.

Tue Sep  1 21:53:05 1992  Brendan Kehoe  (brendan@cygnus.com)

	* Makefile.in (install-common): Copy the g++ and c++ scripts from
	the $(srcdir).
	(install-man): Put semicolons in the right places so the man pages
	get installed.

Tue Sep  1 21:50:48 1992  Ian Lance Taylor  (ian@cygnus.com)

	* config/m68*-none.h: pass -m68851 and -mno68851 to as.

Mon Aug 31 18:34:33 1992  Brendan Kehoe  (brendan@rtl.cygnus.com)

	* Makefile.in (clean): Do a little shuffling of filenames so rm
	doesn't generate a spurious error when BUILD_SO[123] aren't defined.

Mon Aug 31 17:44:03 1992  Ian Lance Taylor  (ian@cygnus.com)

	* Makefile.in, configure.in: Added Makefile variables used to name
	installed programs, and to edit g++ and c++ to generate g++-cross and
	c++-cross which use the right names.  configure.in overrides
	Makefile variable defaults based on the -program_transform_name
	argument.
	g++.sh, c++.sh: renamed back to g++ and c++, as they no longer need
	the @p and @s markers, which were used to support program_prefix and
	program_suffix.

	* config/m680[0234]0-none.h, config/m683[03]2.h: pass underscore
	variants of m68020, etc., to cpp.  Pass non-underscore variants only
	if -ansi was not used.

Mon Aug 31 04:28:16 1992  david d [zoo] zuhn  (zoo at cirdan.cygnus.com)

	* Makefile.in
	(install-common): install gcc as $(target)-gcc not gcc-$(target)

Mon Aug 24 14:40:54 1992  Ian Lance Taylor  (ian@cygnus.com)

	* configure.in, config/ose68000.h, config/ose68k.h,
	config/t-ose68000, config/t-ose68k: renamed OSE configuration files
	to ose.

Wed Aug 19 12:53:02 1992  Mike Stump  (mrs@cygnus.com)

	* Makefile.in (g++): Because of changes in the c++.sh and
	g++.sh scripts, the two files $(target)-gcc and $(target)-c++
	must exist in the working directory.

Tue Aug 18 12:03:59 1992  Ian Lance Taylor  (ian@cygnus.com)

	* configure.in, config/{m68000, m68020, m68030, m68040, m68302,
	m68332}-{none, aout, coff}.h, vx680?0.h, ose68k.h, ose68000.h: added
	m68*-*-aout and m68*-*-coff for entire m68k family.  Organized to
	pass correct -D arguments to cpp and -m arguments to gas.

Mon Jul 27 20:43:18 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* Makefile.in (libgcc1.null) : don't die if creating directories,
	they might already exist from a previous build.

Thu Jul 23 13:58:31 1992  D. V. Henkel-Wallace  (gumby@cygnus.com)

	* Makefile.in: Many cross-compiling changes.  Also, libgcc.a
	is now built differently (build into subdirs; do only one
	ar at the end (a lot faster for systems which insist on a ranlib
	on every update).  Also, libgcc1 can be built out of assembly
	files which go along with gcc, instead of having to live in some
	random directory that can get out of sync -- this makes rms happy.

	* config/OSE68k.h, config/vx68020.h, config/vx68030.h, config/vx6804.h:
	use target_isnan rather than isnan (patch originally from sef).
	more ports probably need this; I just did the 68ks.

	* config/OSE68000.h, config/OSE68k.h, config/t-OSE68000,
	      config/t-OSE68k: new files
	  configure.in: use 'em.
	  vxworks68.h: See yuh! -- merged into lbg1.68k.

	* cross-make: don't suppress libgcc!

	* Makefile.in (install-headers): remove files before making a
	symlink, in case we're installing on top of an existing tree

Wed Jul  1 11:12:05 1992  Mike Stump  (mrs at cygnus.com)

	* Makefile.in (stamp-cp-parse): extract YYEMPTY out of the parser
	generated .c file and put in the parser .h so that cp-lex.c does
	not have to define it.

Fri Jun 26 15:38:43 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* Makefile.in: link crt0.0 into target directory, just like libc.a

Mon Jun 22 18:35:47 1992  Steve Chamberlain  (sac at thepub.cygnus.com)

	* Makefile.in: specs can be built on host, even if cross compiling

Wed Jun  3 13:25:26 1992  Ken Raeburn  (Raeburn at Cygnus.COM)

	* Makefile.in (cp-parse.[ch]): Use move-if-change for renaming bison
	output files that have to be compiled later.  Use a stamp- file to
	prevent extra runs of bison.

Sun May 31 06:36:23 1992  Michael Tiemann  (tiemann at cygnus.com)

	* vx680[1234]0.h: New files.  Now defaults better for each
	processor type.
	* vx68k.h: Deleted.

Sun May 31 06:37:15 1992  Michael Tiemann  (tiemann at cygnus.com)

	* configure.in: Handle m680[01234]0-wrs as a target.

Wed May 20 03:31:14 1992  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)

	* m68k.h: added TARGET_DEFAULT, which wasn't set in a m68k-aout
	  configuration

	* configure.in: moved m68k's aout definition, from host_vendor to
	host_os

Sat May 16 18:01:05 1992  K. Richard Pixley  (rich at rtl.cygnus.com)

	* Makefile.in: hack around sun make bug.

Tue May  5 12:10:04 1992  K. Richard Pixley  (rich at cygnus.com)

	* Makefile.in: remove alloca test which fails to test what was
	  intended.  It doesn't seem necessary to me anyway.

Thu Apr  9 05:21:08 1992  Ken Raeburn  (Raeburn at Cygnus.COM)

	* Makefile.in (install): Depend on "all", so if gcc-cross is going
	to get produced at all, it happens before the install rules run that
	look for it.
	(install-common): Make links for assembler and friends here.
	(install-cross-tools): Don't do it here.

Mon Mar 23 00:33:35 1992  Michael Tiemann  (tiemann at cygnus.com)

	* cp-decl.c (sigsegv): Add some comments about this being
	Cygnus-only code.

	* configure: added --verbose and --silent options.

Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich at 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.

Tue Feb 25 23:00:55 1992  Michael Tiemann  (tiemann at cygnus.com)

	* libgcc2.c (_eprintf): Don't depend on stdio if we don't have it.
	(_bb): Ditto.

	* configure.in: Prepend ${srcdir}/ when testing for
	existence of host- and target_makefile_frags.

Fri Jan 24 10:13:37 1992  Steve Chamberlain  (sac at rtl.cygnus.com)

	* optabs.c (emit_cmp_insn): emit_library_call using INTmode rather
	than SImode.
	(init_optabs): added libcall for *cmpsi, #define for
	memcpy, memcpy and memset, addsi3, subsi3.

Sun Dec  8 14:41:42 1991  Michael Tiemann  (tiemann at rtl.cygnus.com)

	* jump.c (jump_optimize): Generalize support for movcc instructions.

Sat Dec  7 00:06:59 1991  K. Richard Pixley  (rich at rtl.cygnus.com)

	* Makefile.in: remove spaces following hyphens, bsd make can't cope.
	mandir -> man1dir.  install using INSTALL_DATA.  build headers
	into ./include and THEN install using INSTALL_DATA, no fair
	building into an installed directory.  mkdir man1dir.  added
	clean-info.

	* configure.in: targetdependent is now called target_dependent.

Wed Nov 27 09:46:26 1991  Per Bothner  (bothner at cygnus.com)

	* Makefile.in: added compile-man-sysv, on some sysv machines, there
	is no nroff, so they can't compile the man pages. This will create
	the packed .z file for each of the manual pages we release.

Thu Oct 31 05:45:54 1991  Ken Raeburn  (raeburn at cygnus.com)

	* gnulib2.c (__bb_init_func): Changed "#elif" without condition to

	is false, to avoid lossage with some shells.

Fri Oct 25 13:47:06 1991  Roland H. Pesch  (pesch at cygnus.com)

	* Makefile.in: targets for *.dvi; explicit path to find texinfo.tex
	in associated directory (rather than replicating here).

Fri Jun 28 06:42:42 1991  Michael Tiemann  (tiemann at cygint.cygnus.com)

	* gnulib2.c (__bb_init_func): Add handlers for ANSI library.
