problems. I have built an AVR cross-compiler with this, and I have
verified that the test case from PR30149 does not ICE anymore with
this patch. I have asked for some assistance to have this patch
FWIW, the original cc0 patch seemed to work great on a locally-modified
m68k tree. Thanks for the quick fix.
Just to reiterate: This patch seems to work well for mipsel-linux.
