Eliminate more uses of llvm-as and llvm-dis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81293 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-09 00:09:15 +00:00			`; RUN: llc < %s`
fix two problems with machine sinking: 1. Sinking would crash when the first instruction of a block was sunk due to iterator problems. 2. Instructions could be sunk to their current block, causing an infinite loop. This fixes PR3968 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68787 91177308-0d34-0410-b5e6-96231b3b80d8 2009-04-10 16:38:36 +00:00
