Benjamin Kramer b6516aeef1 Reimplement CTPOP legalization with the "best" algorithm from ... http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel In a silly microbenchmark on a 65 nm core2 this is 1.5x faster than the old code in 32 bit mode and about 2x faster in 64 bit mode. It's also a lot shorter, especially when counting 64 bit population on a 32 bit target. I hope this is fast enough to replace Kernighan-style counting loops even when the input is rather sparse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123547 91177308-0d34-0410-b5e6-96231b3b80d8		2011-01-15 20:30:30 +00:00
