Thank you, Patrick Marlier.

Hello, This bug affects all LLVM versions from 2.6 to trunk : http://llvm.org/bugs/show_bug.cgi?id=5081 The workaround I found is to add this : Index: lib/Target/X86/X86Instr64bit.td =================================================================== --- lib/Target/X86/X86Instr64bit.td (revision 105882) +++ lib/Target/X86/X86Instr64bit.td (working copy) @@ -1832,6 +1832,8 @@
