[PATCH] 4.8: Fix RTX sharing problem in ifcvt

2013-04-11 Thread Andreas Krebbel
Hi, the GCC 4.8.0 release unfortunately does not bootstrap on S/390. It fails with a bootstrap comparison failure. The problem is an RTL sharing bug created by ifcvt. I never noticed it because the problem does *not* occur with --enable-checking which I'm usually using on my daily build system.
