* [llvm] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere2019-08-152-17/+17
| | | | | | | | Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. llvm-svn: 369013
* [ORC] Add deprecation warnings to ORCv1 layers and utilities.Lang Hames2019-07-171-3/+4
| | | | | | | | | | | | | | | | | Summary: ORCv1 is deprecated. The current aim is to remove it before the LLVM 10.0 release. This patch adds deprecation attributes to the ORCv1 layers and utilities to warn clients of the change.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [ORC] Rename ORC layers to make the "new" ORC layers the default.Lang Hames2018-10-151-4/+4
| | | | | | | | | | | | | This commit adds a 'Legacy' prefix to old ORC layers and utilities, and removes the '2' suffix from the new ORC layers. If you wish to continue using the old ORC layers you will need to add a 'Legacy' prefix to your classes. If you were already using the new ORC layers you will need to drop the '2' suffix. The legacy layers will remain in-tree until the new layers reach feature parity with them. This will involve adding support for removing code from the new layers, and ensuring that performance is comperable. llvm-svn: 344572

* [ORC] Update JITCompileCallbackManager to support multi-threaded code.Lang Hames2018-05-301-35/+33
| | | | | | | | | Previously JITCompileCallbackManager only supported single threaded code. This patch embeds a VSO (see include/llvm/ExecutionEngine/Orc/Core.h) in the callback manager. The VSO ensures that the compile callback is only executed once and that the resulting address cached for use by subsequent re-entries. llvm-svn: 333490
* [ORC] Rewrite the VSO symbol table yet again. Update related utilities.Lang Hames2018-05-161-0/+1
| | | | | | | | | | | | | | | | | | | VSOs now track dependencies for materializing symbols. Each symbol must have its dependencies registered with the VSO prior to finalization. Usually this will involve registering the dependencies returned in AsynchronousSymbolQuery::ResolutionResults for queries made while linking the symbols being materialized. Queries against symbols are notified that a symbol is ready once it and all of its transitive dependencies are finalized, allowing compilation work to be broken up and moved between threads without queries returning until their symbols fully safe to access / execute. Related utilities (VSO, MaterializationUnit, MaterializationResponsibility) are updated to support dependence tracking and more explicitly track responsibility for symbols from the point of definition until they are finalized. llvm-svn: 332541

* Revert "[ORC] Switch from shared_ptr to unique_ptr for addModule methods."Reid Kleckner2018-03-141-3/+3
| | | | | | | | | | | | | This reverts commit r327566, it breaks test/ExecutionEngine/OrcMCJIT/test-global-ctors.ll. The test doesn't crash with a stack trace, unfortunately. It merely returns 1 as the exit code. ASan didn't produce a report, and I reproduced this on my Linux machine and Windows box. llvm-svn: 327576
* [ORC] Switch from shared_ptr to unique_ptr for addModule methods.Lang Hames2018-03-141-3/+3
| | | | | | | Layer implementations typically mutate module state, and this is better reflected by having layers own the Module they are operating on. llvm-svn: 327566

* [ORC] Remove Layer handles from the layer concept.Lang Hames2018-02-091-6/+6
| | | | | | | | | Handles were returned by addModule and used as keys for removeModule, findSymbolIn, and emitAndFinalize. Their job is now subsumed by VModuleKeys, which simplify resource management by providing a consistent handle across all layers. llvm-svn: 324700
* [ORC] Start migrating ORC layers to use the new ORC Core.h APIs.Lang Hames2018-02-061-29/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular this patch switches RTDyldObjectLinkingLayer to use orc::SymbolResolver and threads the requried changse (ExecutionSession references and VModuleKeys) through the existing layer APIs. The purpose of the new resolver interface is to improve query performance and better support parallelism, both in JIT'd code and within the compiler itself. The most visibile change is switch of the <Layer>::addModule signatures from: Expected<Handle> addModule(std::shared_ptr<ModuleType> Mod, std::shared_ptr<JITSymbolResolver> Resolver) to: Expected<Handle> addModule(VModuleKey K, std::shared_ptr<ModuleType> Mod); Typical usage of addModule will now look like: auto K = ES.allocateVModuleKey(); Resolvers[K] = createSymbolResolver(...); Layer.addModule(K, std::move(Mod)); See the BuildingAJIT tutorial code for example usage. llvm-svn: 324405
* [ORC] Add an Error return to the JITCompileCallbackManager::grow method.Lang Hames2017-09-031-1/+1
| | | | | | | | Calling grow may result in an error if, for example, this is a callback manager for a remote target. We need to be able to return this error to the callee. llvm-svn: 312429
* [ORC] Errorize the ORC APIs.Lang Hames2017-07-072-5/+5
| | | | | | | | This patch updates the ORC layers and utilities to return and propagate llvm::Errors where appropriate. This is necessary to allow ORC to safely handle error cases in cross-process and remote JITing. llvm-svn: 307350
* [Orc] Remove the memory manager argument to addModule, and de-templatize theLang Hames2017-07-041-1/+1
| | | | | | | | | | | | | | | | symbol resolver argument. De-templatizing the symbol resolver is part of the ongoing simplification of ORC layer API. Removing the memory management argument (and delegating construction of memory managers for RTDyldObjectLinkingLayer to a functor passed in to the constructor) allows us to build JITs whose base object layers need not be compatible with RTDyldObjectLinkingLayer's memory mangement scheme. For example, a 'remote object layer' that sends fully relocatable objects directly to the remote does not need a memory management scheme at all (that will be handled by the remote). llvm-svn: 307058

* [ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.Lang Hames2016-08-011-7/+7
| | | | | | | | | | | | | | | | This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class that is capable of lazy materialization (i.e. the symbol definition needn't be emitted until the address is requested). This can be used to support common and weak symbols in the JIT (though this is not implemented in this patch). For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver. For space efficiency a new class, JITEvaluatedSymbol, is introduced that behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an address and symbol flags. Instances of JITEvaluatedSymbol can be used in symbol-tables to avoid paying the space cost of the materializer. llvm-svn: 277386

* [Orc] Add conversion to/from RuntimeDyld::SymbolInfo for JITSymbol.Lang Hames2016-05-311-2/+2
| | | | | | | | | | This tidies up some code that was manually constructing RuntimeDyld::SymbolInfo instances from JITSymbols. It will save more mess in the future when JITSymbol::getAddress is extended to return an Expected<TargetAddress> rather than just a TargetAddress, since we'll be able to embed the error checking in the conversion. llvm-svn: 271350
