*** Revamp the code which handled unreachable code in the function. Now the code is much more efficient for high-degree basic blocks, such as those that occur in the 252.eon SPEC benchmark. For the interested, the time to promote a SINGLE alloca in _ZN7mrScene4ReadERSi function used to be > 3.5s. Now it is < .075s. The function has a LOT of allocas in it, so it appeared to be infinite looping, this should make it much nicer. :) llvm-svn: 8863 |
