Restore circa-0.5.22 capabilities of `g77' driver:
* Make-lang.in (g77spec.o): Depend on f/version.h.
(g77version.o): New rule to compile g77 version info.
(g77$(exeext)): Depend on and link in g77version.o.
* g77spec.c: Rewrite to be more like 0.5.22 version
of g77.c, making filtering of command line smarter
so mixed Fortran and C (etc.) can be compiled, verbose
version info can be obtained, etc.
* lang-specs.h (f77-version): New "language" to support
"g77 -v" command under new gcc 2.8 regime.
* lex.c (ffelex_file_fixed): If -fnull-version, just
substitute a "source file" that prints out version info.
* top.c, top.h: Support -fnull-version.
* lang-specs.h: Use "%O" instead of OO macro to specify
object extension. Remove old stringizing cruft.
* Make-lang.in (g77.c, g77spec.o, g77.o, g77$(exeext),
g77-cross$(exeext), f771,
$(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi,
$(srcdir)/f/intdoc.texi,
f77.install-common, f77.install-info, f77.install-man,
f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2,
f77.stage3, f77.stage4, f77.distdir): Don't do anything
unless user specified "f77" or "F77" in $LANGUAGES either
during configuration or explicitly. For convenience of
various tests and to work around lack of the assignment
"LANGUAGES=$(BOOT_LANGUAGES)" in the "make stage1" command
of "make bootstrap" in gcc, use a touch file named "lang-f77"
to communicate whether this is the case.
* Make-lang.in (F77_FLAGS_TO_PASS): Delete this macro,
replace with minimal expansion of its former self in
each of the two instances where it was used.
* Makefile.in (HOST_CC): Delete this definition.
* com.c (index, rindex): Delete these declarations.
* proj.h: (isascii): Delete this.
* Make-lang.in (f77.install-common): Warn if `f77-install-ok'
flag-file exists, since it no longer triggers any activity.
Rename libf2c.a and f2c.h to libg2c.a and g2c.h,
normalize and simplify g77/libg2c build process:
* Make-lang.in: Remove all support for overwriting
/usr/bin/f77 etc., or whatever the actual names are
via $(prefix) and $(local_prefix). (g++ overwrites
/usr/bin/c++, but then it's often the only C++ compiler
on the system; f77 often exists on systems that are
installing g77.)
(f77.realclean): Remove obsolete target.
(g77.c, g77$(exeext)): Minor changes to look more like g++'s
stuff.
(f771): Now built with srcdir=gcc/f, not srcdir=gcc, to be
more like g++ and such.
(f/Makefile): Removed, as g++ doesn't need this rule.
(f77.install-common): No longer install f77, etc.
(f77.install-man): No longer install f77.1.
(f77.uninstall): No longer uninstall f77, f77.1, etc.
(f77.stage1, f77.stage2, f77.stage3, f77.stage4): Do work
only if "f77" appears in $(LANGUAGES).
(Note: gcc's Makefile.in's bootstrap target should set
LANGUAGES=$(BOOT_LANGUAGES) when making the stage1 target.)
* Makefile.in: Update vis-a-vis gcc/cp/Makefile.in.
(none): Remove.
(g77-only): Relocate.
(all.indirect, f771, *.o): Now assumes current directory
is this dir (gcc/f), not the parent directory.
(TAGS): Remove "echo 'parse.y,0' >> TAGS ;" line.
* config-lang.in: Delete commented-out code.
Fix stagestuff definition. Add more stuff to
diff_excludes definition. Don't create any directories.
Set outputs to f/Makefile, to get variable substition
to happen (what does that really do, anyway?!).
* g77spec.c: Rename libf2c to libg2c.
* com.h: Remove all of the gcc back-end decls,
since egcs should have all of them correct.
* com.c: Include "proj.h" before anything else,
as that's how things are supposed to work.
* ste.c: Ditto.
* bad.c: Include "flags.j" here, since some diagnostics
check flag_pedantic_errors.
* Makefile.in (f/*.o): Rebuild dependencies via
deps-kinda.
* output.j: New source file.
* Make-lang.in (F77_SRCS): Update accordingly.
* Makefile.in (OUTPUT_H): Ditto.
(deps-kinda): Ditto.
* com.c: Include "output.j" here.
* lex.c: Ditto.
From-SVN: r20506
* g77.info*: Rebuilt.
* config-lang.in: Don't demand the backend patch.
* com.c (lang_printable_name): Second argument is now an int. Don't
store into the value of the second argument.
* top.c (ffe_decode_option): Temporarily disable setting
of "Toon" loop options until we figure out how to address
them.
Make g77 work with gcc3.
