Dan Gohman	40503396da	Eliminate more uses of llvm-as and llvm-dis. llvm-svn: 81290	2009-09-08 23:54:48 +00:00
Dan Gohman	31599685c7	When both x/y and x%y are needed (x and y both scalar integer), compute both results with a single div or idiv instruction. This uses new X86ISD nodes for DIV and IDIV which are introduced during the legalize phase so that the SelectionDAG's CSE can automatically eliminate redundant computations. llvm-svn: 42308	2007-09-25 18:23:27 +00:00
