Thu May 28 21:32:18 1998 Craig Burley <burley@gnu.org> 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
