示例1:
bool
EdgeCaseAnalysis::AllUsesTruncate(MInstruction *m)
{
for (MUseIterator use = m->usesBegin(); use != m->usesEnd(); use++) {
// See #809485 why this is allowed
if (use->node()->isResumePoint())
continue;
MDefinition *def = use->node()->toDefinition();
if (def->isTruncateToInt32())
continue;
if (def->isBitAnd())
continue;
if (def->isBitOr())
continue;
if (def->isBitXor())
continue;
if (def->isLsh())
continue;
if (def->isRsh())
continue;
if (def->isBitNot())
continue;
if (def->isAdd() && def->toAdd()->isTruncated())
continue;
if (def->isSub() && def->toSub()->isTruncated())
continue;
// cannot use divide, since |truncate(int32(x/y) + int32(a/b)) != truncate(x/y+a/b)|
return false;
}

}示例2: Max
int

// If all uses truncate, the return value must be at least 1. If anything doesn't truncate
// 0 is explicitly returned.
