mysterymath added inline comments.
================
Comment at: llvm/lib/Target/X86/X86CallingConv.td:522
// Mingw64 and native Win64 use Win64 CC
CCIfSubtarget<"isTargetWin64()", CCDelegateTo<RetCC_X86_Win64_C>>,
----------------
You'll need to add switching for Win64 here too; this appears to be the
convention used for assigning return values.
================
Comment at: llvm/lib/Target/X86/X86CallingConv.td:1162
def CSR_Win64 : CalleeSavedRegs<(add CSR_Win64_NoSSE,
(sequence "XMM%u", 6, 15))>;
----------------
It looks like you'll need some stitching in X86RegisterInfo.cpp to cause the
Win64 set of callee-saved registers to be used for UEFI targets.
