The problem was that I slipped a change required for shrink-wrapping, namely I used getFirstTerminator instead of the getLastNonDebugInstr that was here before the refactoring, whereas the surrounding code is not yet patched for that. Original message: [X86] Refactor the prologue emission to prepare for shrink-wrapping. - Add a late pass to expand pseudo instructions (tail call and EH returns). Instead of doing it in the prologue emission. - Factor some static methods in X86FrameLowering to ease code sharing. NFC.
