Chris Lattner 1add46ddfa Carve out a place in instcombine to put transformations which work knowing that their ... result is non-zero. Implement an example optimization (PR9814), which allows us to transform: A / ((1 << B) >>u 2) into: A >>u (B-2) which we compile into: _divu3: ## @divu3 leal -2(%rsi), %ecx shrl %cl, %edi movl %edi, %eax ret instead of: _divu3: ## @divu3 movb %sil, %cl movl $1, %esi shll %cl, %esi shrl $2, %esi movl %edi, %eax xorl %edx, %edx divl %esi, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131860 91177308-0d34-0410-b5e6-96231b3b80d8		2011-05-22 18:18:41 +00:00
