llvm/test/CodeGen/X86: Update tests with -mattr=-bmi not to take BMI, corresponding to Craig's r189742. AMD Piledriver builder detected failures. llvm-svn: 189754 2013-09-02 14:00:46 +02:00			`; RUN: llc < %s -march=x86 -mattr=-bmi \| FileCheck %s`
- More aggressively coalescing away copies whose source is defined by an implicit_def. - Added insert_subreg coalescing support. llvm-svn: 49448 2008-04-09 22:57:25 +02:00
Enable i16 to i32 promotion by default. llvm-svn: 102493 2010-04-28 10:30:49 +02:00			`define fastcc i32 @t() nounwind {`

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.
