ARM/atomicrmw_minmax.ll: Fix RUN line. llvm-svn: 164687 2012-09-26 12:12:20 +02:00			`; RUN: llc -march=arm -mcpu=cortex-a9 < %s \| FileCheck %s`
Fix ordering of operands on lowering of atomicrmw min/max nodes on ARM. llvm-svn: 164685 2012-09-26 11:48:32 +02:00
Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.
