The code in X86TargetLowering::IsEligibleForTailCallOptimization() has this part:
// The callee has to preserve all registers the caller needs to preserve.
const X86RegisterInfo *TRI = Subtarget.getRegisterInfo();
const uint32_t *CallerPreserved = TRI->getCallPreservedMask(MF, CallerCC);

if (!TRI->regmaskSubsetEqual(CallerPreserved, CalleePreserved))
return false;
}
which usually checks that this is fine. Maybe that code l...
