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

Utils	Add a parameter to ConstantFoldTerminator() that callers can use to ask it to also clean up the condition of any conditional terminator it folds to be unconditional, if that turns the condition into dead code. This just means it calls RecursivelyDeleteTriviallyDeadInstructions() in strategic spots. It defaults to the old behavior.	2011-05-22 16:24:18 +00:00
