* [Orc] New JIT APIs.Lang Hames2015-01-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new set of JIT APIs to LLVM. The aim of these new APIs is to cleanly support a wider range of JIT use cases in LLVM, and encourage the development and contribution of re-usable infrastructure for LLVM JIT use-cases. These APIs are intended to live alongside the MCJIT APIs, and should not affect existing clients. Included in this patch: 1) New headers in include/llvm/ExecutionEngine/Orc that provide a set of components for building JIT infrastructure. Implementation code for these headers lives in lib/ExecutionEngine/Orc. 2) A prototype re-implementation of MCJIT (OrcMCJITReplacement) built out of the new components. 3) Minor changes to RTDyldMemoryManager needed to support the new components. These changes should not impact existing clients. 4) A new flag for lli, -use-orcmcjit, which will cause lli to use the OrcMCJITReplacement class as its underlying execution engine, rather than MCJIT itself. Tests to follow shortly. Special thanks to Michael Ilseman, Pete Cooper, David Blaikie, Eric Christopher, Justin Bogner, and Jim Grosbach for extensive feedback and discussion. llvm-svn: 226940
* Assigning and copying command line option objects shouldn't be allowed.Chris Bieneman2015-01-221-1/+1
| | | | | | | | | | | | | | | Summary: The default copy and assignment operators for these objects probably don't actually do what the clients intend, so they should be deleted. Places using the assignment operator to set the value of an option should cast to the option's data type first to call into the override for operator=. Places using the copy constructor just need to be changed to not copy (i.e. passing by const reference instead of value).

* [MCJIT] Delete the JTIMemoryManager and associated APIs.Lang Hames2014-09-231-7/+4
| | | | | | | | | | This patch removes the old JIT memory manager (which does not provide any useful functionality now that the old JIT is gone), and migrates the few remaining clients over to SectionMemoryManager. http://llvm.org/PR20848 llvm-svn: 218316

* Give ExecutionEngine of top level buffers.Rafael Espindola2014-08-261-3/+1
| | | | | | | Long term the idea if for the engine to not own the buffers, but for now this is consistent with the rest of the API. llvm-svn: 216484

* Modernize raw_fd_ostream's constructor a bit.Rafael Espindola2014-08-251-2/+2
| | | | | | | | | | Take a StringRef instead of a "const char *". Take a "std::error_code &" instead of a "std::string &" for error. A create static method would be even better, but this patch is already a bit too big. llvm-svn: 216393

* Don't own the buffer in object::Binary.Rafael Espindola2014-08-191-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries (like Archive) and we had to create dummy buffers just to handle that. It is also a bad fit for IRObjectFile where the Module wants to own the buffer too. Keeping this ownership would make supporting IR inside native objects particularly painful. This patch focuses in lib/Object. If something elsewhere used to own an Binary, now it also owns a MemoryBuffer. This patch introduces a few new types. * MemoryBufferRef. This is just a pair of StringRefs for the data and name. This is to MemoryBuffer as StringRef is to std::string. * OwningBinary. A combination of Binary and a MemoryBuffer. This is needed for convenience functions that take a filename and return both the buffer and the Binary using that buffer. The C api now uses OwningBinary to avoid any change in semantics. I will start a new thread to see if we want to change it and how. llvm-svn: 216002

* Nuke the old JIT.Rafael Espindola2014-08-071-34/+8
| | | | | | | | | I am sure we will be finding bits and pieces of dead code for years to come, but this is a good start. Thanks to Lang Hames for making MCJIT a good replacement! llvm-svn: 215111

* PR19553: Memory leak in RuntimeDyldELF::createObjectImageFromFileDavid Blaikie2014-04-291-1/+1
| | | | | | | | | | | | | | | | This starts in MCJIT::getSymbolAddress where the unique_ptr<object::Binary> is release()d and (after a cast) passed to a single caller, MCJIT::addObjectFile. addObjectFile calls RuntimeDyld::loadObject. RuntimeDld::loadObject calls RuntimeDyldELF::createObjectFromFile And the pointer is never owned at this point. I say this point, because the alternative codepath, RuntimeDyldMachO::createObjectFile certainly does take ownership, so this seemed like a good hint that this was a/the right place to take ownership. llvm-svn: 207580

* Replace OwningPtr<T> with std::unique_ptr<T>.Ahmed Charles2014-03-061-3/+3
| | | | | | | | | | This compiles with no changes to clang/lld/lldb with MSVC and includes overloads to various functions which are used by those projects and llvm which have OwningPtr's as parameters. This should allow out of tree projects some time to move. There are also no changes to libs/Target, which should help out of tree targets have time to move, if necessary. llvm-svn: 203083

* Replace the F_Binary flag with a F_Text one.Rafael Espindola2014-02-241-1/+1
| | | | | | | | | After this I will set the default back to F_None. The advantage is that before this patch forgetting to set F_Binary would corrupt a file on windows. Forgetting to set F_Text produces one that cannot be read in notepad, which is a better failure mode :-) llvm-svn: 202052

* Sanitize MCJIT remote executionRenato Golin2014-01-141-2/+5
| | | | | | | | | | | | MCJIT remote execution (ChildTarget+RemoteTargetExternal) protocol was in dire need of refactoring. It was fail-prone, had no error reporting and implemented the same message logic on every single function. This patch rectifies it, and makes it work on ARM, where it was randomly failing. Other architectures shall profit from this change as well, making their buildbots and releases more reliable. llvm-svn: 199261
