示例1: escapeRegNode

/// to frameescape, if any, in the entry block and append RegNode to the list
/// of arguments.

// Find the call to frameescape and extract its arguments.
IntrinsicInst *EscapeCall = nullptr;
for (Instruction &I : F.getEntryBlock()) {
IntrinsicInst *II = dyn_cast<IntrinsicInst>(&I);
if (II && II->getIntrinsicID() == Intrinsic::frameescape) {
EscapeCall = II;
break;
}
}

// Replace the call (if it exists) with new one. Otherwise, insert at the end
// of the entry block.
