Subject: [Bug middle-end/31699] [Regression 4.3] -march=opteron -ftree-vectorize generates wrong code
Date: Fri, 27 Apr 2007 10:35:00 -0000 [thread overview]

--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13450&action=view) [edit]
This patch fixes the testcase from comment #2 and Polyhedron rnflow failure in
both 32bit (-m32 -msse2) and 64bit modes. The loop is still vectorized and
cvtps2pd insns are still present in the asm dump.
