[LLVMdev] SROA is slow when compiling a large basic block
...will affect the
common case.
This will also help speed up the execution of code in other places. For
example, these two functions are called when GVN::processLoad is called and
iterate over a basic block's instruction list to determine the order of two
(load and stores) instructions.:
llvm::isPotentiallyReachable
// Linear scan, start at 'A', see whether we hit 'B' or the end first.
for (BasicBlock::const_iterator I = A, E = BB->end(); I != E; ++I) {
if (&*I == B)
return true;
}
DominatorTree::dominates
// Loop through the basic block until we f...
