Fixs PR13719. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163107 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-03Fix more fallout from r158919, similar to PR13547.Bob Wilson
This code used to only handle malloc-like calls, which do not read memory. r158919 changed it to check isNoAliasFn(), which includes strdup-like and realloc-like calls, but it was not checking for dependencies on the memory read by those calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163106 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-02Not all targets have efficient ISel code generation for select instructions.Nadav Rotem
For example, the ARM target does not have efficient ISel handling for vector selects with scalar conditions. This patch adds a TLI hook which allows the different targets to report which selects are supported well and which selects should be converted to CF duting codegen prepare. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163093 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-02LoopRotation: Make the brute force DomTree update more brute force.Benjamin Kramer
We update until we hit a fixpoint. This is probably slow but also slightly simplifies the code. It should also fix the occasional invalid domtrees observed when building with expensive checking. I couldn't find a case where this had a measurable slowdown, but if someone finds a pathological case where it does we may have to find a cleverer way of updating dominators here. Thanks to Duncan for the test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163091 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-02Rename ANDROIDEABI to Android.Logan Chien
Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI". Note: We are not using ANDROID because several projects are using "-DANDROID" as the conditional compilation flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163087 91177308-0d34-0410-b5e6-96231b3b80d8

zeros or all ones. A vector bool with just ones isn't suitable for masking with. No test case unfortunately as i couldn't find a target which fit all the conditions needed to hit this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163075 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-01Limit domain conversion to cases where it won't break dep chains.Tim Northover
NEON domain conversion was too heavy-handed with its widened registers, which could have stripped existing instructions of their dependency, leaving them vulnerable to scheduling errors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163070 91177308-0d34-0410-b5e6-96231b3b80d8
