Roll r127459 back in: Optimize trivial branches in CodeGenPrepare, which often get created from the lowering of objectsize intrinsics. Unfortunately, a number of tests were relying on llc not optimizing trivial branches, so I had to add an option to allow them to continue to test what they originally tested. This fixes <rdar://problem/8785296> and <rdar://problem/9112893>. llvm-svn: 127498 2011-03-11 22:52:04 +01:00			`;RUN: llc --march=cellspu -disable-cgp-branch-opts %s -o - \| FileCheck %s`

Mark the SPU 'lr' instruction to never have side effects. This allows the fast regiser allocator to remove redundant register moves. Update a set of tests that depend on the register allocator to be linear scan. llvm-svn: 106420 2010-06-21 17:08:16 +02:00			`;CHECK: ai {{\$.}}, $3, -1`
