示例1: handleFinalSuspend
// Rewrite final suspend point handling. We do not use suspend index to
// represent the final suspend point. Instead we zero-out ResumeFnAddr in the
// coroutine frame, since it is undefined behavior to resume a coroutine
// suspended at the final suspend point. Thus, in the resume function, we can
// simply remove the last case (when coro::Shape is built, the final suspend
// point (if present) is always the last element of CoroSuspends array).
// In the destroy function, we add a code sequence to check if ResumeFnAddress
// is Null, and if so, jump to the appropriate label to handle cleanup from the
// final suspend point.
static void handleFinalSuspend(IRBuilder<> &Builder, Value *FramePtr,
coro::Shape &Shape, SwitchInst *Switch,
bool IsDestroy) {
assert(Shape.HasFinalSuspend);
auto FinalCaseIt = std::prev(Switch->case_end());
BasicBlock *ResumeBB = FinalCaseIt->getCaseSuccessor();
Switch->removeCase(FinalCaseIt);
if (IsDestroy) {
BasicBlock *OldSwitchBB = Switch->getParent();
auto *NewSwitchBB = OldSwitchBB->splitBasicBlock(Switch, "Switch");
Builder.SetInsertPoint(OldSwitchBB->getTerminator());
auto *GepIndex = Builder.CreateConstInBoundsGEP2_32(Shape.FrameTy, FramePtr,
0, 0, "ResumeFn.addr");
auto *Load = Builder.CreateLoad(GepIndex);
auto *NullPtr =
