2013-03-20Use pre-inc, pre-dec when possible.Jakub Staszak
They are generally faster (at least not slower) than post-inc, post-dec. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177608 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20[lit] Avoid CRLFs in bash scripts on WindowsReid Kleckner
Native Windows Python will do line ending translation by default, which we don't want in bash scripts. If we're not native Windows Python, then 'b' is ignored. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177602 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Correct cost model for vector shift on AVX2Michael Liao
- After moving logic recognizing vector shift with scalar amount from DAG combining into DAG lowering, we declare to customize all vector shifts even vector shift on AVX is legal. As a result, the cost model needs special tuning to identify these legal cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177586 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Call the new llvm_gcov_init function to register the environment.Bill Wendling
Use the new `llvm_gcov_init' function to register the writeout and flush functions. The initialization function will also call `atexit' for some cleanups and final writout calls. But it does this only once. This is better than checking for the `main' function, because in a library that function may not exist. <rdar://problem/12439551> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177579 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Make sure TableGen exits with an error code after printing errors.Jakob Stoklund Olesen
This makes it possible to report multiple errors in one invocation. There are already calls to PrintError in CodeGenDAGPatterns.cpp which previously would not cause TableGen to fail. <rdar://problem/13463339> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177573 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Revert "pre-RA-sched: fix TargetOpcode usage"Christian Konig
This reverts commit 06091513c283c863296f01cc7c2e86b56bb50d02. The code is obviously wrong, but the trivial fix causes inefficient code generation on X86. Somebody with more knowledge of the code needs to take a look here.

2013-03-20[SROA] Don't preserve the IR names in release builds.Chandler Carruth
This is espcially important because the new SROA pass goes to great lengths to provide helpful names for debugging, and as a consequence they can become very slow to render. Good for between 5% and 15% of the SROA runtime on some slow test cases such as the one in PR15412. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177495 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-20Reorder the DIFile parameter in DINameSpaceDavid Blaikie

a raw directory/file pair This makes DIType's first non-tag parameter the same as DIFile's, allowing them to both share the common implementation of getFilename/getDirectory in DIScope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177467 91177308-0d34-0410-b5e6-96231b3b80d8
