During type legalization we often use the SIGN_EXTEND_INREG SDNode. When this SDNode is legalized during the LegalizeVector phase, it is scalarized because non-simple types are automatically marked to be expanded. In this patch we add support for lowering SIGN_EXTEND_INREG manually. This fixes CodeGen/X86/vec_sext.ll when running with the '-promote-elements' flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135144 91177308-0d34-0410-b5e6-96231b3b80d8 |
