[PATCH] D19338: New code hoisting pass based on GVN (optimistic approach)

[Sebastian Pop via llvm-commits]

sebpop added a comment.

We measured the total number of instructions executed when "clang -cc1" is compiling all the preprocessed files of the llvm test-suite through valgrind:

with patch: 931904066692
 without: 928877989824

Overall compilation overhead of the new pass is 0.32%.
