ARM: yet another round of ARM test clean ups llvm-svn: 205586 2014-04-04 01:47:24 +02:00			`; RUN: llc -mtriple=thumb-eabi -mcpu=arm1156t2-s -mattr=+thumb2 %s -o - \| FileCheck %s`
Make tBX_RET and tBX_RET_vararg predicable. The normal tBX instruction is predicable, so there's no reason the pseudos for using it as a return shouldn't be. Gives us some nice code-gen improvements as can be seen by the test changes. In particular, several tests now have to disable if-conversion because it works too well and defeats the test. llvm-svn: 134746 2011-07-08 23:50:04 +02:00			`; If-conversion defeats the purpose of this test, which is to check CBZ`
Improve test cases from r134746. Use memory barriers to force if-conversion off for these tests instead of the internal llc command line option ifcvt-limit. llvm-svn: 134986 2011-07-12 18:06:01 +02:00			`; generation, so use memory barrier instruction to make sure it doesn't`

Don't put IT instruction before conditional branches. llvm-svn: 75361 2009-07-11 09:26:20 +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.
