Instead of bailing out when we see loads, analyze them. If we can prove that the loaded-from address must escape, then we can conclude that a load from that address must escape too and therefore cannot alias a non-addr-taken global. When checking if a Value can alias a non-addr-taken global, if the Value is a LoadInst of a non-global, recurse instead of bailing. If we can follow a trail of loads up to some base that is captured, we know by inference that all the loads we followed are also captured. llvm-svn: 251017 |
