* [X86] Reduce complexity of the LEA optimization pass, by Andrey Turetsky.Alexey Bataev2016-01-111-7/+28
| | | | | | | In the OptimizeLEA pass keep instructions' positions in the basic block saved and use them for calculation of the distance between two instructions instead of std::distance. This reduces complexity of the pass from O(n^3) to O(n^2) and thus the compile time. Differential Revision: http://reviews.llvm.org/D15692 llvm-svn: 257328

* clang-format: Slightly row back on r257257.Daniel Jasper2016-01-112-1/+18
| | | | | | | | | | | | | | | | | | | | | r257257 change the way clang-format enforces line breaks after a templated type has been line-wrapped. This was to fix an incorrect line break if BinPackParameters is set to false. However, it also leads to an unwanted line break in a different case. Thus, for now, only do this when BinPackParameters is false. This isn't ideal yet, but helps us until we have a better solution. With BinPackParameters: Before: void fffffffffff(aaaaaaaaaaaaaaaaaaaaaaaaaaa<aaaaaaaaaaaaaaaaaaaaaaa, aaaaaaaaaa> aaaaaaaaaa); After: void fffffffffff( aaaaaaaaaaaaaaaaaaaaaaaaaaa<aaaaaaaaaaaaaaaaaaaaaaa, aaaaaaaaaa> aaaaaaaaaa); llvm-svn: 257325

* [clang-tidy] Fix a false positive in google-runtime-memsetAlexander Kornienko2016-01-112-11/+17
| | | | | | | | | | | | | | | | | google-runtime-memset no longer issues a warning if the fill char value is known to be an invalid fill char count. Namely, it no longer warns for these: memset(p, 0, 0); memset(p, -1, 0); In both cases, swapping the last two args would either be useless (there is no actual bug) or wrong (it would introduce a bug).

* Centralize the handling of attach permissions on linux in testsPavel Labath2016-01-1110-134/+42
| | | | | | | | | | | | | | | Summary: On linux we need the process to give us special permissions before we can attach to it. Previously, the code for this was copied into every file that needed it. This moves the code to a central place to reduce code duplication. Reviewers: clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15992 llvm-svn: 257319

However, we need to use a unique declaration for both store and lookup in VisitedCallees. This patch fixes issues with analysis in topological order. A simple test is included. Patch by Alex Sidorin!

* [Orc] Add support for remote JITing to the ORC API.Lang Hames2016-01-119-0/+2068
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds utilities to ORC for managing a remote JIT target. It consists of: 1. A very primitive RPC system for making calls over a byte-stream. See RPCChannel.h, RPCUtils.h. 2. An RPC API defined in the above system for managing memory, looking up symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h. 3. An interface for creating high-level JIT components (memory managers, callback managers, stub managers, etc.) that operate over the RPC API. See OrcRemoteTargetClient.h. 4. A helper class for building servers that can handle the RPC calls. See OrcRemoteTargetServer.h. The system is designed to work neatly with the existing ORC components and functionality. In particular, the ORC callback API (and consequently the CompileOnDemandLayer) is supported, enabling lazy compilation of remote code. Assuming this doesn't trigger any builder failures, a follow-up patch will be committed which tests these utilities by using them to replace LLI's existing remote-JITing demo code. llvm-svn: 257305

* [RuntimeDyld] Add a notifyObjectLoaded method to RuntimeDyld::MemoryManager.Lang Hames2016-01-103-1/+21

* [RuntimeDyld] Add alignment arguments to the reserveAllocationSpace method ofLang Hames2016-01-105-25/+36
| | | | | | | | | | | | | | RuntimeDyld::MemoryManager. The RuntimeDyld::MemoryManager::reserveAllocationSpace method is called when object files are loaded, and gives clients a chance to pre-allocate memory for all segments. Previously only the size of each segment (code, ro-data, rw-data) was supplied but not the alignment. This hasn't caused any problems so far, as most clients allocate via the MemoryBlock interface which returns page-aligned blocks. Adding alignment arguments enables finer grained allocation while still satisfying alignment restrictions. llvm-svn: 257294
* [SectionMemoryManager] Don't just drop the RO free listKeno Fischer2016-01-101-3/+0
| | | | | | | | | | | | | In r255760, I optimized the SectionMemoryManager to make better use of virtual memory on platforms where the allocation granularity was bigger than the protection granularity. As part of this, fixing up the free list became more complicated and was moved into `applyMemoryGroupPermissions`. Unfortunately, I forgot to actually remove the call that drops the free list for RO memory (I did remove the corresponding one for RX memory), defeating the whole optimization. llvm-svn: 257293

* [ADT] Add an abstraction for embedding an integer within a pointer-likeChandler Carruth2016-01-103-0/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | type. This makes it easy and safe to use a set of flags as one elmenet of a tagged union with pointers. There is quite a bit of code that has historically done this by casting arbitrary integers to "pointers" and assuming that this was safe and reliable. It is neither, and has started to rear its head by triggering safety asserts in various abstractions like PointerLikeTypeTraits when the integers chosen are invariably poor choices for *some* platform and *some* situation. Not to mention the (hopefully unlikely) prospect of one of these integers actually getting allocated! With this, it will be straightforward to build type safe abstractions like this without being error prone. The abstraction itself is also remarkably simple thanks to the implicit conversion. This use case and pattern was also independently created by the folks working on Swift, and they're going to incrementally add any missing functionality they find.

* [ADT] Add a sum type abstraction for pointer-like types.Chandler Carruth2016-01-103-0/+319
| | | | | | | | | | | | | | | | | | | | | | | | | | This is a much more general and powerful form of PointerUnion. It provides a reasonably complete sum type (from type theory) for pointer-like types. It has several significant advantages over the existing PointerUnion infrastructure: 1) It allows more than two pointer types to participate without awkward nesting structures. 2) It directly exposes the tag so that it is convenient to write switches over the possible members. 3) It can re-use the same type for multiple tag values, something that has been worked around by either abusing PointerIntPair or defining nonce types and doing unsafe pointer casting. 4) It supports customization of the PointerLikeTypeTraits used for specific member types. This means it could (in theory) be used even with types that are over-aligned on allocation to expose larger numbers of bits to the tag. All in all, I think it is at least complimentary to the existing infrastructure, and a strict improvement for some use cases. Differential Revision: http://reviews.llvm.org/D15843 llvm-svn: 257282
