------- Comment #3 from kkojima at gcc dot gnu dot org 2005-10-03 22:28 -------
This PR was discussed at the thread of gcc-patches list statring
with http://gcc.gnu.org/ml/gcc-patches/2005-09/msg01527.html and
Joern pointed out that we must improve the reload infrastrucure to
fix this PR. There is an argument about whether it's appropriate
for stage3 or not. I've checked in the patch in
http://gcc.gnu.org/ml/gcc-patches/2005-09/msg01952.html
as a temporary workwround on mainline and 4.0-branch under Joern's
approval. It gets rid of the ICEs for the testcase, though it
doesn't fix the real problem. So please don't close this PR ATM.
