* Revert part of r193291, restoring the deletion of loaded objects.Chandler Carruth2013-10-24
| | | | | | | | | | | Without this, customers of the MCJIT were leaking memory like crazy. It's not really clear what the *right* memory management is here, so I'm not trying to add lots of tests or other logic, just trying to get us back to a better baseline. I'll follow up on the original commit to figure out the right path forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193323 91177308-0d34-0410-b5e6-96231b3b80d8

* Path: Recognize Windows compiled resource file.Rui Ueyama2013-10-15
| | | | | | | | | | | | | | Some background: One can pass compiled resource files (.res files) directly to the linker on Windows. If a resource file is given, the linker will run "cvtres" command in background to convert the resource file to a COFF file to link it. What I'm trying to do with this patch is to make the linker to recognize the resource file by file magic, so that it can run cvtres command.

* 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

Hopefully someone will eventually get a chance to implement this feature, but in the meantime, it is better to put things back the way the were.

* Fixed RuntimeDyldELF absolute relocations.Richard Mitton2013-08-16
| | | | | | | | | If an ELF relocation is pointed at an absolute address, it will have a symbol ID of zero. RuntimeDyldELF::processRelocationRef was not previously handling this case, and was instead trying to handle it as a section-relative fixup. I think this is the right fix here, but my elf-fu is poor on some of the more exotic platforms, so I'd appreciate it if anyone with greater knowledge could verify this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188572 91177308-0d34-0410-b5e6-96231b3b80d8
* Support X86_64_GOTLoad relocations in RuntimeDyldMachO by treating them theLang Hames2013-08-15
| | | | | | | | | | | | | | | | | | same way as X86_64_GOT relocations. The 'Load' part of GOTLoad is just an optimization hint for the linker anyway, and can be safely ignored. This patch also fixes some minor issues with the relocations introduced while processing an X86_64_GOT[Load]: the addend for the GOT entry should always be zero, and the addend for the replacement relocation at the original offset should be the same as the addend of the relocation being replaced.

* [PowerPC] Support powerpc64le as a syntax-checking target.Bill Schmidt2013-07-26
| | | | | | | | | | | | | | | | | | | | | | | | This patch provides basic support for powerpc64le as an LLVM target. However, use of this target will not actually generate little-endian code. Instead, use of the target will cause the correct little-endian built-in defines to be generated, so that code that tests for __LITTLE_ENDIAN__, for example, will be correctly parsed for syntax-only testing. Code generation will otherwise be the same as powerpc64 (big-endian), for now. The patch leaves open the possibility of creating a little-endian PowerPC64 back end, but there is no immediate intent to create such a thing. The LLVM portions of this patch simply add ppc64le coverage everywhere that ppc64 coverage currently exists. There is nothing of any import worth testing until such time as little-endian code generation is implemented. In the corresponding Clang patch, there is a new test case variant to ensure that correct built-in defines for little-endian code are generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187179 91177308-0d34-0410-b5e6-96231b3b80d8

* [mips] Use pristine object file while processing relocations.Akira Hatanaka2013-07-24
| | | | | | | | | | | | | | | | | | | | | Similar to ARM change r182800, dynamic linker will read bits/addends from the original object rather than from the object that might have been patched previously. For the purpose of relocations for MCJIT stubs on MIPS, we internally use otherwise unused MIPS relocations. The change also enables MCJIT unit tests for MIPS (EL/BE), and the following two tests now pass: - MCJITTest.return_global and - MCJITTest.multiple_functions.
