2013-03-26Split out the IRReader header and the utility functions it provides intoChandler Carruth
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
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
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
2012-12-04Sort the #include lines for tools/...Chandler Carruth
Again, tools are trickier to pick the main module header for than library source files. I've started to follow the pattern of using LLVMContext.h when it is included as a stub for program source files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169252 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-27Modifying lli to use the SectionMemoryManager.Andrew Kaylor
The functionality of SectionMemoryManager is equivalent to the LLIMCJITMemoryManager being replaced except that it allocates memory as RW and later changes it to RX or R as needed. The page permissions are set in the call to MCJIT::finalizeObject. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168722 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-05Add a method to indicate section address re-assignment is finished.Andrew Kaylor
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

2012-09-05MCJIT: Add faux remote target execution to lli for the MCJIT.Jim Grosbach
Simulate a remote target address space by allocating a seperate chunk of memory for the target and re-mapping section addresses to that prior to execution. Later we'll want to have a truly remote process, but for now this gets us closer to being able to test the remote target functionality outside LLDB. rdar://12157052 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163216 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28LLI: move instruction cache tweaks.Jim Grosbach

2012-05-16Added LLIMCJITMemoryManager to the lli. This manager will be used for MCJIT ↵Danil Malyshev
instead of DefaultJIMMemoryManager. It's more flexible for MCJIT tasks, in addition it's provides a invalidation instruction cache for code sections which will be used before JIT code will be executed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156933 91177308-0d34-0410-b5e6-96231b3b80d8

Previously let the JITEmitter do it. That's rather odd, and doesn't play nice with the MCJIT, so move the (trivial) logic up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147967 91177308-0d34-0410-b5e6-96231b3b80d8

Enhance the X86 asmparser to produce ranges in the one case that was annoying me, for example: test.s:10:15: error: invalid operand for instruction movl 0(%rax), 0(%edx) ^~~~~~~ It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use ranges where appropriate if someone is interested. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142106 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-20- Move CodeModel from a TargetMachine global option to MCCodeGenInfo.Evan Cheng

2011-03-18Beginnings of MC-JIT code generation.Jim Grosbach
Proof-of-concept code that code-gens a module to an in-memory MachO object. This will be hooked up to a run-time dynamic linker library (see: llvm-rtdyld for similarly conceptual work for that part) which will take the compiled object and link it together with the rest of the system, providing back to the JIT a table of available symbols which will be used to respond to the getPointerTo*() queries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127916 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.
