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			`; RUN: llvm-as < %s \| llc -march=x86 \| grep 111`
Don't lower srem/urem X%C to X-X/C*C unless the division is actually optimized. This avoids creating illegal divisions when the combiner is running after legalize; this fixes PR1815. Also, it produces better code in the included testcase by avoiding the subtract and multiply when the division isn't optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44341 91177308-0d34-0410-b5e6-96231b3b80d8 2007-11-26 23:46:11 +00:00
