Summary: LTO generates different alignments
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: hjl.to...@gmail.com
On Linux/ia32, when I compile SPEC CPU 2006 is with
-O3 -mfpmath=sse -msse2 -funroll-loops -ffast-math -fwhole-program
-flto=jobserver -fuse-linker-plugin
using GCC configured with --with-plugin-ld=ld, using binutils as of
2010-10-20 CVS, I got
464.h264ref
