示例1:
bool
MIRGenerator::usesSimd()
{
if (usesSimdCached_)
return usesSimd_;
usesSimdCached_ = true;
for (ReversePostorderIterator block = graph_->rpoBegin(),
end = graph_->rpoEnd();
block != end;
block++)
{
// It's fine to use MInstructionIterator here because we don't have to
// worry about Phis, since any reachable phi (or phi cycle) will have at
// least one instruction as an input.
for (MInstructionIterator inst = block->begin(); inst != block->end(); inst++) {
// Instructions that have SIMD inputs but not a SIMD type are fine
// to ignore, as their inputs are also reached at some point. By
// induction, at least one instruction with a SIMD type is reached
// at some point.
if (IsSimdType(inst->type())) {
MOZ_ASSERT(SupportsSimd);
usesSimd_ = true;
return true;
}
}
}
usesSimd_ = false;
return false;
