This revision attempts to recognize following population-count pattern: while(a) { c++; ... ; a &= a - 1; ... }, where <c> and <a>could be used multiple times in the loop body. TODO: On X8664 and ARM, __buildin_ctpop() are not expanded to a efficent instruction sequence, which need to be improved in the following commits. Reviewed by Nadav, really appreciate! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168931 91177308-0d34-0410-b5e6-96231b3b80d8		2012-11-29 19:38:54 +00:00
