示例1: overlaps
bool LiveInterval::overlaps(const LiveInterval &Other,
const CoalescerPair &CP,
const SlotIndexes &Indexes) const {
assert(!empty() && "empty interval");
if (Other.empty())
return false;
// Use binary searches to find initial positions.
const_iterator I = find(Other.beginIndex());
const_iterator IE = end();
if (I == IE)
return false;
const_iterator J = Other.find(I->start);
const_iterator JE = Other.end();
if (J == JE)
return false;
for (;;) {
// J has just been advanced to satisfy:
assert(J->end >= I->start);
// Check for an overlap.
if (J->start < I->end) {
// I and J are overlapping. Find the later start.
SlotIndex Def = std::max(I->start, J->start);
// Allow the overlap if Def is a coalescable copy.
if (Def.isBlock() ||
!CP.isCoalescable(Indexes.getInstructionFromIndex(Def)))
return true;
}
// Advance the iterator that ends first to check for more overlaps.
if (J->end > I->end) {
std::swap(I, J);
std::swap(IE, JE);
}
// Advance J until J->end >= I->start.
do
if (++J == JE)
return false;
