* MCJIT-remote: __main should be resolved in child context.NAKAMURA Takumi2013-10-27
| | | | | | | | | | | | | | | | - Mark tests as XFAIL:cygming in test/ExecutionEngine/MCJIT/remote. Rather to suppress them, I'd like to leave them running as XFAIL. - Revert r193472. RecordMemoryManager no longer resolves __main on cygming. There are a couple of issues. - X86 Codegen emits "call __main" in @main for targeting cygming. It is useless in JIT. FYI, tests are passing when emitting __main is disabled. - Current remote JIT does not resolve any symbols in child context. FIXME: __main should be disabled, or remote JIT should resolve __main. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193498 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixing problems in lli's RemoteMemoryManager.Andrew Kaylor2013-10-11
| | | | | | | | | | This fixes a problem from a previous check-in where a return value was omitted. Previously the remote/stubs-remote.ll and remote/stubs-sm-pic.ll tests were reporting passes, but they should have been failing. Those tests attempt to link against an external symbol and remote symbol resolution is not supported. The old RemoteMemoryManager implementation resulted in local symbols being used for resolution and the child process crashed but the test didn't notice. With this check-in remote symbol resolution fails, and so the test (correctly) fails. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192514 91177308-0d34-0410-b5e6-96231b3b80d8

* This threads SectionName through the allocateCodeSection/allocateDataSection ↵Filip Pizlo2013-10-02
| | | | | | | | | | | | | | | | | | | | APIs, both in C++ and C land. It's useful for the memory managers that are allocating a section to know what the name of the section is. At a minimum, this is useful for low-level debugging - it's customary for JITs to be able to tell you what memory they allocated, and as part of any such dump, they should be able to tell you some meta-data about what each allocation is for. This allows clients that supply their own memory managers to do this. Additionally, we also envision the SectionName being useful for passing meta-data from within LLVM to an LLVM client. This changes both the C and C++ APIs, and all of the clients of those APIs within LLVM. I'm assuming that it's safe to change the C++ API because that API is allowed to change. I'm assuming that it's safe to change the C API because we haven't shipped the API in a release yet (LLVM 3.3 doesn't include the MCJIT memory management C API). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191804 91177308-0d34-0410-b5e6-96231b3b80d8

* SectionMemoryManager shouldn't be a JITMemoryManager. Previously, the Filip Pizlo2013-05-14
| | | | | | | | | | | | | | | | | | | EngineBuilder interface required a JITMemoryManager even if it was being used to construct an MCJIT. But the MCJIT actually wants a RTDyldMemoryManager. Consequently, the SectionMemoryManager, which is meant for MCJIT, derived from the JITMemoryManager and then stubbed out a bunch of JITMemoryManager methods that weren't relevant to the MCJIT. This patch fixes the situation: it teaches the EngineBuilder that RTDyldMemoryManager is a supertype of JITMemoryManager, and that it's appropriate to pass a RTDyldMemoryManager instead of a JITMemoryManager if we're using the MCJIT. This allows us to remove the stub methods from SectionMemoryManager, and make SectionMemoryManager a direct subtype of RTDyldMemoryManager. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181820 91177308-0d34-0410-b5e6-96231b3b80d8

There may still be some missing dependencies, I'm still sifting through the bots and my builds, but this is a step in the right direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177988 91177308-0d34-0410-b5e6-96231b3b80d8
* Split out the IRReader header and the utility functions it provides intoChandler Carruth2013-03-26
| | | | | | | | | | | | | | | | | | | | | | | | its own library. These functions are bridging between the bitcode reader and the ll parser which are in different libraries. Previously we didn't have any good library to do this, and instead played fast and loose with a "header only" set of interfaces in the Support library. This really doesn't work well as evidenced by the recent attempt to add timing logic to the these routines. As part of this, make them normal functions rather than weird inline functions, and sink the implementation into the library. Also clean up the header to be nice and minimal. This requires updating lots of build system dependencies to specify that the IRReader library is needed, and several source files to not implicitly rely upon the header file to transitively include all manner of other headers. If you are using IRReader.h, this commit will break you (the header moved) and you'll need to also update your library usage to include 'irreader'. I will commit the corresponding change to Clang momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177971 91177308-0d34-0410-b5e6-96231b3b80d8
* Provide workaround for PR 15130.Andrew Kaylor2013-02-25
| | | | | | | | This changes the RecordingMemoryManager in lli to use mapped memory rather than malloc to allocate memory for sections and uses a 'near' MemoryBlock to keep the allocations together. This works around a problem in MCJIT where relocations are applied to a generated image immediately oupon generation, which isn't appropriate for the remote case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176057 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-05
| | | | | | Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8
