There has to be a more efficient way to do this. If nothing else, the first 6 characters of that memcmp are always equal, and for groups of intrinsics like llvm.arm.neon.v*, a trie-like search would be better. llvm/ADT/Trie.h doesn't quite do what this needs (no prefix searching), and it...

Any takers? This patch improves on the previous one by making getIntrinsicID() inline. -------------- next part -------------- An HTML attachment was scrubbed...
