* [Orc] Enable ORC execution unit tests on non-windows platforms.Lang Hames2016-01-181-1/+1
| | | | | | | | | | | Previously these were Darwin-only. Since the switch to direct binary emission of stubs, trampolines and resolver blocks, these should work on other *nix platforms too. These tests can be enabled on Windows once known issues with ORC's handling of Windows symbol mangling (see e.g. https://llvm.org/PR25940) have been fixed. llvm-svn: 258031
* [Orc] Add support for remote JITing to the ORC API.Lang Hames2016-01-112-0/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 alignment arguments to the reserveAllocationSpace method ofLang Hames2016-01-101-2/+3
| | | | | | | | | | | | | | 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

* [Orc][RuntimeDyld] Prevent duplicate calls to finalizeMemory on shared memoryLang Hames2016-01-093-4/+86
| | | | | | | | | | | | | | | | | | | | | | | managers. Prior to this patch, recursive finalization (where finalization of one RuntimeDyld instance triggers finalization of another instance on which the first depends) could trigger memory access failures: When the inner (dependent) RuntimeDyld instance and its memory manager are finalized, memory allocated (but not yet relocated) by the outer instance is locked, and relocation in the outer instance fails with a memory access error. This patch adds a latch to the RuntimeDyld::MemoryManager base class that is checked by a new method: RuntimeDyld::finalizeWithMemoryManagerLocking, ensuring that shared memory managers are only finalized by the outermost RuntimeDyld instance. This allows ORC clients to supply the same memory manager to multiple calls to addModuleSet. In particular it enables the use of user-supplied memory managers with the CompileOnDemandLayer which must reuse the supplied memory manager for each function that is lazily compiled. llvm-svn: 257263

* [Orc] Directly emit machine code for the x86 resolver block and trampolines.Lang Hames2015-11-032-5/+5
| | | | | | | | | | | | | | Bypassing LLVM for this has a number of benefits: 1) Laziness support becomes asm-syntax agnostic (previously lazy jitting didn't work on Windows as the resolver block was in Darwin asm). 2) For cross-process JITs, it allows resolver blocks and trampolines to be emitted directly in the target process, reducing cross process traffic. 3) It should be marginally faster. llvm-svn: 251933

* [PM/AA] Rebuild LLVM's alias analysis infrastructure in a way compatibleChandler Carruth2015-09-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with the new pass manager, and no longer relying on analysis groups. This builds essentially a ground-up new AA infrastructure stack for LLVM. The core ideas are the same that are used throughout the new pass manager: type erased polymorphism and direct composition. The design is as follows: - FunctionAAResults is a type-erasing alias analysis results aggregation interface to walk a single query across a range of results from different alias analyses. Currently this is function-specific as we always assume that aliasing queries are *within* a function. - AAResultBase is a CRTP utility providing stub implementations of various parts of the alias analysis result concept, notably in several cases in terms of other more general parts of the interface. This can be used to implement only a narrow part of the interface rather than the entire interface. This isn't really ideal, this logic should be hoisted into FunctionAAResults as currently it will cause a significant amount of redundant work, but it faithfully models the behavior of the prior infrastructure. - All the alias analysis passes are ported to be wrapper passes for the legacy PM and new-style analysis passes for the new PM with a shared result object. In some cases (most notably CFL), this is an extremely naive approach that we should revisit when we can specialize for the new pass manager. - BasicAA has been restructured to reflect that it is much more fundamentally a function analysis because it uses dominator trees and loop info that need to be constructed for each function. All of the references to getting alias analysis results have been updated to use the new aggregation interface. All the preservation and other pass management code has been updated accordingly. The way the FunctionAAResultsWrapperPass works is to detect the available alias analyses when run, and add them to the results object. This means that we should be able to continue to respect when various passes are added to the pipeline, for example adding CFL or adding TBAA passes should just cause their results to be available and to get folded into this. The exception to this rule is BasicAA which really needs to be a function pass due to using dominator trees and loop info. As a consequence, the FunctionAAResultsWrapperPass directly depends on BasicAA and always includes it in the aggregation. This has significant implications for preserving analyses. Generally, most passes shouldn't bother preserving FunctionAAResultsWrapperPass because rebuilding the results just updates the set of known AA passes. The exception to this rule are LoopPass instances which need to preserve all the function analyses that the loop pass manager will end up needing. This means preserving both BasicAAWrapperPass and the aggregating FunctionAAResultsWrapperPass. Now, when preserving an alias analysis, you do so by directly preserving that analysis. This is only necessary for non-immutable-pass-provided alias analyses though, and there are only three of interest: BasicAA, GlobalsAA (formerly GlobalsModRef), and SCEVAA. Usually BasicAA is preserved when needed because it (like DominatorTree and LoopInfo) is marked as a CFG-only pass. I've expanded GlobalsAA into the preserved set everywhere we previously were preserving all of AliasAnalysis, and I've added SCEVAA in the intersection of that with where we preserve SCEV itself. One significant challenge to all of this is that the CGSCC passes were actually using the alias analysis implementations by taking advantage of a pretty amazing set of loop holes in the old pass manager's analysis management code which allowed analysis groups to slide through in many cases. Moving away from analysis groups makes this problem much more obvious. To fix it, I've leveraged the flexibility the design of the new PM components provides to just directly construct the relevant alias analyses for the relevant functions in the IPO passes that need them. This is a bit hacky, but should go away with the new pass manager, and is already in many ways cleaner than the prior state. Another significant challenge is that various facilities of the old alias analysis infrastructure just don't fit any more. The most significant of these is the alias analysis 'counter' pass. That pass relied on the ability to snoop on AA queries at different points in the analysis group chain. Instead, I'm planning to build printing functionality directly into the aggregation layer. I've not included that in this patch merely to keep it smaller. Note that all of this needs a nearly complete rewrite of the AA documentation. I'm planning to do that, but I'd like to make sure the new design settles, and to flesh out a bit more of what it looks like in the new pass manager first.
