* Fix known typosAlp Toker2014-01-24
| | | | | | | Sweep the codebase for common typos. Includes some changes to visible function names that were misspelt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200018 91177308-0d34-0410-b5e6-96231b3b80d8
* Add target analysis passes to the codegen pipeline for MCJIT.Juergen Ributzka2014-01-23
| | | | | | | | | | | This patch adds the target analysis passes (usually TargetTransformInfo) to the codgen pipeline. We also expose now the AddAnalysisPasses method through the C API, because the optimizer passes would also benefit from better target-specific cost models.

* Make the llvm mangler depend only on DataLayout.Rafael Espindola2014-01-03
| | | | | | | | | | | | | | Before this patch any program that wanted to know the final symbol name of a GlobalValue had to link with Target. This patch implements a compromise solution where the mangler uses DataLayout. This way, any tool that already links with Target (llc, clang) gets the exact behavior as before and new IR files can be mangled without linking with Target. With this patch the mangler is constructed with just a DataLayout and DataLayout is extended to include the information the Mangler needs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198438 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the isImplicitlyPrivate argument of getNameWithPrefix.Rafael Espindola2013-12-05
| | | | | | | | | | | | getSymbolWithGlobalValueBase use is to create a name of a new symbol based on the name of an existing GV. Assert that and then remove the last call to pass true to isImplicitlyPrivate. This gives the mangler API a 1:1 mapping from GV to names, which is what we need to drop the mangler dependency on the target (and use an extended datalayout instead). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196472 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
* Add EH support to the MCJIT.Rafael Espindola2013-05-05

* This exposes more MCJIT options via the C API:Filip Pizlo2013-05-01
| | | | | | | | | | | | | | | | | | | | | | | CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like. Previously it was only possible to create an MCJIT that used CodeModel::JITDefault. EnableFastISel: It's now possible to turn on the fast instruction selector. The CodeModel option required some trickery. The problem is that previously, we were ensuring future binary compatibility in the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the bindings then bzero the remaining bits. This works great but assumes that the bitwise zero equivalent of any field is a sensible default value. But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model. In both of those, the default for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero. Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp illustrates the change, as does the comment in ExecutionEngine.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180893 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

If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
