示例1: get
void MInstrEffects::get(const IRInstruction* inst,
const FrameStateMgr& frame,
LocalStateHook& hook) {
// If the base for this instruction is a local address, the helper call might
// have side effects on the local's value
auto const base = inst->src(minstrBaseIdx(inst->op()));
auto const locInstr = base->inst();
// Right now we require that the address of any affected local is the
// immediate source of the base tmp. This isn't actually specified in the ir
// spec right now but will intend to make it more general soon.
if (locInstr->op() != LdLocAddr) return;
