Putting the back end in a library seems like a good idea to me,
never mind whether or not we're really hitting command line length limits.
Here's a patch - has been bootstrapped on i386-linux, testsuite is running
now. Please let us know if it solves your problem.
Note this inflicts ordering constraints on cc1* link lines; $(BACKEND)
has to come after the front end objects. Also, toplev.o has to be
left out of the library since it contains main.
It occurred to me, while generating this patch, that we could easily
have nonrecursive builds within the gcc directory by moving all the logic
from subdirs' Makefile.in to their Make-lang.in. The objc directory is
already like that. I bet the build system would get significantly simpler.
I may try to do this in a successor patch.
zw
* Makefile.in: Remove toplev.o from OBJS. Add rule to make
libbackend.a; add libbackend.a to STAGESTUFF. Add BACKEND
variable. Use BACKEND when linking cc1, not OBJS. Add BACKEND
to VOL_FILES.
ch:
* Make-lang.in (cc1chill): Depend on $(BACKEND), not stamp-objlist.
* Makefile.in (cc1chill): Link with $(BACKEND). Define BACKEND,
eliminate C_OBJS (was commented out), OBJS, OBJDEPS.
cp:
* Make-lang.in (cc1plus): Depend on $(BACKEND), not stamp-objlist.
* Makefile.in: Add C_OBJS, BACKEND; delete OBJS, OBJDEPS.
(cc1plus): Link with $(BACKEND) and $(C_OBJS).
f:
* Make-lang.in (f771): Depend on $(BACKEND), not stamp-objlist.
* Makefile.in: Add BACKEND; delete OBJS, OBJDEPS.
(f771): Link with $(BACKEND).
java:
* Make-lang.in (jc1, jv-scan): Depend on $(BACKEND), not stamp-objlist.
* Makefile.in: Add BACKEND; delete OBJS, OBJDEPS.
(jc1): Link with $(BACKEND).
(jv-scan): Depend on version.o, not all of $(OBJS) or $(BACKEND).
objc:
* Make-lang.in (cc1obj): Link with $(BACKEND).
