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 -march=x86 \| grep "\\\\\\\<mul"`
Add some generic expansion logic for SMULO and UMULO. Fixes UMULO support for x86, and UMULO/SMULO for many architectures, including PPC (PR4201), ARM, and Cell. The resulting expansion isn't perfect, but it's not bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73477 91177308-0d34-0410-b5e6-96231b3b80d8 2009-06-16 06:58:29 +00:00
