------- Comment #5 from ubizjak at gmail dot com 2009-06-25 17:32 ------- The problem is also present on 4.5.0. The executable won't segfault, because -O0 generates more temporaries on stack. However:
xorps %xmm1, %xmm1 movlps 56(%esp), %xmm1 (*) movhps 64(%esp), %xmm1 xorps %xmm0, %xmm0 movlps 48(%esp), %xmm0 (**) movhps 56(%esp), %xmm0 addps %xmm1, %xmm0 (*) This slot is not initialized (**) This one belongs to "a". -- ubizjak at gmail dot com changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail| |4.5.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40550
