From 009fed31760b2b3fc0395bedf2f6d9f25b9bbb32 Mon Sep 17 00:00:00 2001 From: Hans Wennborg Date: Tue, 15 Dec 2015 23:21:46 +0000 Subject: [PATCH] Fix "Not having LAHF/SAHF" assert. It wants to assert that the subtarget is 64-bit, not the register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@255703 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/X86/X86InstrInfo.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lib/Target/X86/X86InstrInfo.cpp b/lib/Target/X86/X86InstrInfo.cpp index 7f0766df26f..e028683c63b 100644 --- a/lib/Target/X86/X86InstrInfo.cpp +++ b/lib/Target/X86/X86InstrInfo.cpp @@ -4417,7 +4417,8 @@ void X86InstrInfo::copyPhysReg(MachineBasicBlock &MBB, int AX = is64 ?
