[LLVMdev] RFC: Tail call optimization X86
...ult.getValue(0), DAG);
}
would change to (pseudo code)
SDOperand SelectionDAGLegalize::LegalizeOp(SDOperand Op) {
SDOperand Result = Op;
...
case ISD::CALL:
// The only option for this is to custom lower it.
Result = modifyCallSoThatTailAttributeReallyIndicatesWhetherThisCallIsEligibleForTailCallOptimization(Result);
Tmp3 = TLI.LowerOperation(Result.getValue(0), DAG);
}
because any point after that (e.g. scheduling) would be to late
because the target specific loweringcode (e.g. LowerCALL ->
LowerCCCall)
