Jan, I'm afraid this is an outfall of your patch(es) yesterday:
/sw/test/gcc/cvs/gcc/libgcc2.c: In function `__lshrdi3':
/sw/test/gcc/cvs/gcc/libgcc2.c:266: Internal compiler error in emit_jump_to_block_after, at bb-reorder.c:546
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
gmake[3]: *** [libgcc/./_lshrdi3.o] Error 1
gmake[2]: *** [stmp-multilib] Error 2
(Given how often sparc-* has failed to bootstrap recently, I think it
should be tested before most changes to the cfg* stuff in the future
are actually installed.)

I am just looking at the problem (I bootstrapped sparc to verify my other
CFG changes). It appears to be latent bug tought..
(the EDGE_FALLTHRU to exit should not be present at all when RTL epilogues
are used)

Apparently, following check got lost.
The patch compiles fine on i386, but does nothing, solves the crash and I can't
access sparc machine till next week, as our laboratory is relocating.
Could you please test whether it works for you?

Note that I can't test sparc till next week, but I am moving the development to
the branch tomorrow (I just want to get the cleanups in in cases that are
relativly safe and has huge volume of changes to avoid merging problems later).
I will bootstrap the sparc from branch then more regulary.

Yes, it solves the bootstrap failure I reported:

This cannot be installed under the obvious to fix the bootstrap issue,
can it?

Sure, I just wanted to know that it really helps.
Commiting the patch.
