* Replace Execution Engine's mutex with std::recursive_mutex.Zachary Turner2014-06-18
| | | | | | | | | | | | | This change has a bit of a trickle down effect due to the fact that there are a number of derived implementations of ExecutionEngine, and that the mutex is not tightly encapsulated so is used by other classes directly.

* [ARM] [MC] Refactor the constant pool classesWeiming Zhao2014-06-18
| | | | | | | | | | | | | ARMTargetStreamer implements ConstantPool and AssmeblerConstantPools to keep track of assembler-generated constant pools that are used for ldr-pseudo. When implementing ldr-pseudo for AArch64, these two classes can be reused. So this patch factors them out from ARM target to the general MC lib. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211198 91177308-0d34-0410-b5e6-96231b3b80d8

* Random Number Generator (llvm)JF Bastien2014-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers. The current implementation uses C++11 facilities and is therefore not cryptographically secure. The RNG is salted with the text of the current command line invocation. In addition, a user may specify a seed (reproducible builds). In clang, the seed can be set via -frandom-seed=X In the back end, the seed can be set via -rng-seed=X This is the llvm part of the patch. clang part: D3391 Reviewers: ahomescu, rinon, nicholas, jfb Reviewed By: jfb Subscribers: jfb, perl Differential Revision: http://reviews.llvm.org/D3390 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211145 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | These were being used as unreferenced parameters to enforce that the methods must not be called without holding a mutex, but all of the methods in question were internal, and the methods were only exposed through an interface whose entire purpose was to serialize access to these structures, so expecting the methods to be accessed under a mutex is reasonable enough.

| | | | | | | | | | | | | | Init-order and use-after-return modes can currently be enabled by runtime flags. use-after-scope mode is not really working at the moment. The only problem I see is that users won't be able to disable extra instrumentation for init-order and use-after-scope by a top-level Clang flag. But this instrumentation was implicitly enabled for quite a while and we didn't hear from users hurt by it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210924 91177308-0d34-0410-b5e6-96231b3b80d8
* Finishing touch for the std::error_code transition.Rafael Espindola2014-06-13
| | | | | | | | | | | While std::error_code itself seems to work OK in all platforms, there are few annoying differences with regards to the std::errc enumeration. This patch adds a simple llvm enumeration, which will hopefully avoid build breakages in other platforms and surprises as we get more uses of std::error_code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210920 91177308-0d34-0410-b5e6-96231b3b80d8
* IR: add "cmpxchg weak" variant to support permitted failure.Tim Northover2014-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a weak variant of the cmpxchg operation, as described in C++11. A cmpxchg instruction with this modifier is permitted to fail to store, even if the comparison indicated it should. As a result, cmpxchg instructions must return a flag indicating success in addition to their original iN value loaded. Thus, for uniformity *all* cmpxchg instructions now return "{ iN, i1 }". The second flag is 1 when the store succeeded. At the DAG level, a new ATOMIC_CMP_SWAP_WITH_SUCCESS node has been added as the natural representation for the new cmpxchg instructions. It is a strong cmpxchg. By default this gets Expanded to the existing ATOMIC_CMP_SWAP during Legalization, so existing backends should see no change in behaviour. If they wish to deal with the enhanced node instead, they can call setOperationAction on it. Beware: as a node with 2 results, it cannot be selected from TableGen. Currently, no use is made of the extra information provided in this patch. Test updates are almost entirely adapting the input IR to the new scheme. Summary for out of tree users: ------------------------------ + Legacy Bitcode files are upgraded during read. + Legacy assembly IR files will be invalid. + Front-ends must adapt to different type for "cmpxchg". + Backends should be unaffected by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210903 91177308-0d34-0410-b5e6-96231b3b80d8
