"Fix alias slowdown" patch miscompiles 464.h264ref in SPEC CPU


2006

Hi Daniel,

Do you have access to SPEC CPU 2006? Your patch

http://gcc.gnu.org/ml/gcc-patches/2006-12/msg00225.html

causes gcc 4.3 to miscompile 464.h264ref in SPEC CPU 2006 with
-O2 -ffast-math on Linux/x86-64. 464.h264ref compiled with gcc 4.3
generates incorrect output. We are working on a small testcase.


H.J.
