2012-09-13Better const handling for RuntimeDyld and MCJIT.Jim Grosbach
mapSectionAddress() wasn't consistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163843 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-13MCJIT: relocation addends encoded in the target aren't quite so easy.Jim Grosbach
The assumption that the target address for the relocation will always be sizeof(intptr_t) and will always contain an addend for the relocation value is very wrong. Default to no addend for now. rdar://12157052 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163765 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30It doesn't make sense to move symbol relocations to section relocations whenEli Bendersky
relocations are resolved. It's much more reasonable to do this decision when relocations are just being added - we have all the information at that point. Also a bit of renaming and extra comments to clarify extensions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155819 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-16Implement GDB integration for source level debugging of code JITed usingPreston Gurd
the MCJIT execution engine. The GDB JIT debugging integration support works by registering a loaded object image with a pre-defined function that GDB will monitor if GDB is attached. GDB integration support is implemented for ELF only at this time. This integration requires GDB version 7.0 or newer.

2012-03-30Re-factored RuntimeDyLd:Danil Malyshev
1. The main works will made in the RuntimeDyLdImpl with uses the ObjectFile class. RuntimeDyLdMachO and RuntimeDyLdELF now only parses relocations and resolve it. This is allows to make improvements of the RuntimeDyLd more easily. In addition the support for COFF can be easily added. 2. Added ARM relocations to RuntimeDyLdELF. 3. Added support for stub functions for the ARM, allowing to do a long branch. 4. Added support for external functions that are not loaded from the object files, but can be loaded from external libraries. Now MCJIT can correctly execute the code containing the printf, putc, and etc. 5. The sections emitted instead functions, thanks Jim Grosbach. MemoryManager.startFunctionBody() and MemoryManager.endFunctionBody() have been removed. 6. MCJITMemoryManager.allocateDataSection() and MCJITMemoryManager. allocateCodeSection() used JMM->allocateSpace() instead of JMM->allocateCodeSection() and JMM->allocateDataSection(), because I got an error: "Cannot allocate an allocated block!" with object file contains more than one code or data sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153754 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-26Made RuntimeDyldMachO support vanilla i386Sean Callanan
relocations. The algorithm is the same as that for x86_64. Scattered relocations, a feature present in i386 but not on x86_64, are not yet supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153466 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-22Revert a series of commits to MCJIT to get the build working in CMakeChandler Carruth
(and hopefully on Windows). The bots have been down most of the day because of this, and it's not clear to me what all will be required to fix it. The commits started with r153205, then r153207, r153208, and r153221. The first commit seems to be the real culprit, but I couldn't revert a smaller number of patches. When resubmitting, r153207 and r153208 should be folded into r153205, they were simple build fixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153241 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-21Re-factored RuntimeDyld.Danil Malyshev
Added ExecutionEngine/MCJIT tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153221 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-20RuntimeDyldMachO has the ability to keep track ofSean Callanan
relocations (i.e., pieces of data whose addresses are referred to elsewhere in the binary image) and update the references when the section containing the relocations moves. The way this works is that there is a map from section IDs to lists of relocations. Because the relocations are associated with the section containing the data being referred to, they are updated only when the target moves. However, many data references are relative and also depend on the location of the referrer. To solve this problem, I introduced a new data structure, Referrer, which simply contains the section being referred to and the index of the relocation in that section. These referrers are associated with the source containing the reference that needs to be updated, so now regardless of which end of the relocation moves, the relocation will now be updated correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153147 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-07Improved support in RuntimeDyldMachO for generatingSean Callanan
code that will be relocated into another memory space. Now when relocations are resolved, the address of the relocation in the host memory (where the JIT is) is passed separately from the address that the relocation will be at in the target memory (where the code will run). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152264 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-13Fix various issues (or do cleanups) found by enabling certain MSVC warnings.Ahmed Charles
- Use unsigned literals when the desired result is unsigned. This mostly allows unsigned/signed mismatch warnings to be less noisy even if they aren't on by default. - Remove misplaced llvm_unreachable. - Add static to a declaration of a function on MSVC x86 only. - Change some instances of calling a static function through a variable to simply calling that function while removing the unused variable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150364 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-12Expose the ELFObjectFile class directly in the Object/ELF.h header, similarlyEli Bendersky
to what's done for MachO and COFF. This allows advanced uses of the class to be implemented outside the Object library. In particular, the DyldELFObject subclass is now moved into its logical home - ExecutionEngine/RuntimeDyld.

2012-01-21RuntimeDyld alignment adjustment from MachO file.Jim Grosbach
The MachO file stores section alignment as log2(alignment-in-bytes). The allocation routines want the raw alignment-in-bytes value, so adjust for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148604 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-16MCJIT support for non-function sections.Jim Grosbach
Move to a by-section allocation and relocation scheme. This allows better support for sections which do not contain externally visible symbols. Flesh out the relocation address vs. local storage address separation a bit more as well. Remote process JITs use this to tell the relocation resolution code where the code will live when it executes. The startFunctionBody/endFunctionBody interfaces to the JIT and the memory manager are deprecated. They'll stick around for as long as the old JIT does, but the MCJIT doesn't use them anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148258 91177308-0d34-0410-b5e6-96231b3b80d8
