--- Comment #3 from Martin Jansa <Martin.Jansa at gmail dot com> --- Hi Terry, > With Bin's patch at http://gcc.gnu.org/ml/gcc-cvs/2013-03/msg00784.html, we > will get correct rtx cost. I can confirm that with 4.8.1 + this patch I don't see ICE anymore. > I believe this is the cause of the issue and am doing back port to 4.8 branch. Please do, thanks. I'll start one more build with 4.8.1 but without this patch to check that it wasn't fixed by some other change between 4.8.0 and 4.8.1 - but if I don't reply today, then it's really fixed by Bin's patch.
