Chris Lattner 9506c930aa When factoring multiply expressions across adds, factor both ... positive and negative forms of constants together. This allows us to compile: int foo(int x, int y) { return (x-y) + (x-y) + (x-y); } into: _foo: ## @foo subl %esi, %edi leal (%rdi,%rdi,2), %eax ret instead of (where the 3 and -3 were not factored): _foo: imull $-3, 8(%esp), %ecx imull $3, 4(%esp), %eax addl %ecx, %eax ret this started out as: movl 12(%ebp), %ecx imull $3, 8(%ebp), %eax subl %ecx, %eax subl %ecx, %eax subl %ecx, %eax ret This comes from PR5359. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92381 91177308-0d34-0410-b5e6-96231b3b80d8		2010-01-01 01:13:15 +00:00
