Eliminate more uses of llvm-as and llvm-dis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81290 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-08 23:54:48 +00:00			`; RUN: llc < %s -mtriple=i686-pc-linux-gnu \| grep -- -1985 \| count 1`
Fix for PR2164: allow transforming arbitrary-width unsigned divides into multiplies. Some more cleverness would be nice, though. It would be nice if we could do this transformation on illegal types. Also, we would prefer a narrower constant when possible so that we can use a narrower multiply, which can be cheaper. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60283 91177308-0d34-0410-b5e6-96231b3b80d8 2008-11-30 06:02:26 +00:00			`target datalayout = "e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32"`
