[Bug 728737] Radeon gallium driver: X crashes at startup due to use of SSE2 on non-SSE2 capable machines

Thinking about it again. Maybe in llvm we have a better CPU detection. ;-)

Ok, I tried obs build of X11:XOrg llvm on the affected machine, but llvm doesn't build there. During the stage2, bin/llvm-tblgen says "Illegal instruction" and the build indeed terminates. The binary dies at (guess where): movsd (%eax),%xmm0 of llvm::SmallVectorImpl::push_back(llvm::cl::parser<ActionType>::OptionInfo const&) It very looks like LLVM incorrectly determines CPU capabilities. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
