I don't think you need to look at the basic blocks to figure out if a local variable has its address taken. You can look through referenced variables and see if it is a local variable and TREE_ADDRESSABLE is set. This should speed up the code a lot. Though that might has some false positives with arrays but that is ok because you are checking if there are any arrays already anyways. Thanks, Andrew Pinski
