I've only once seens this in a -j32 sparc-sun-solaris2.11 build, but only
during
stage 2 for the sparcv9 multilib. It never occured during any other parallel
build, including x86_64-unknown-linux-gnu with -j96. Unfortunately, I cannot
see how this can happen: we do have this dependency in libgcc/Makefile.in:
$(libgcc-objects) $(libgcc-s-objects) $(libgcc-eh-objects) \
$(libgcov-objects) \
$(libunwind-objects) $(libunwind-s-objects) \
$(extra-parts): libgcc_tm.h
with
EXTRA_PARTS = @extra_parts@
(which expands to
EXTRA_PARTS = gmon.o crtbegin.o crtend.o crt1.o gcrt1.o crtfastmath.o
in the sparc-sun-solaris2.11 case)
extra-parts = libgcc-extra-parts
.PHONY: libgcc-extra-parts
libgcc-extra-parts: $(EXTRA_PARTS)
>From my understanding, thus should provide the necessary dependency, but for
some
reason it doesn't. Perhaps Paolo has a suggestion?
