2012-05-01RuntimeDyld cleanup:Eli Bendersky
- Improved parameter names for clarity - Added comments - emitCommonSymbols should return void because its return value is not being used anywhere - Attempt to reduce the usage of the RelocationValueRef type.

2012-05-01RuntimeDyld code cleanup:Eli Bendersky
- There's no point having a different type for the local and global symbol tables. - Renamed SymbolTable to GlobalSymbolTable to clarify the intention - Improved const correctness where relevant git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155898 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.

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

2012-03-22Revert 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

2012-03-20RuntimeDyldMachO 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

Renamed methods caseBegin, caseEnd and caseDefault with case_begin, case_end, and case_default. Added some notes relative to case iterators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152532 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-08Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*". ConstCaseIt is just a read-only iterator. CaseIt is read-write iterator; it allows to change case successor and case value. Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters. Main way of iterator usage looks like this: SwitchInst *SI = ... // intialize it somehow for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) { BasicBlock *BB = i.getCaseSuccessor(); ConstantInt *V = i.getCaseValue(); // Do something. } If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method. If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method. There are also related changes in llvm-clients: klee and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152297 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-07Improved support in RuntimeDyldMachO for generatingSean Callanan
code that will be relocated into another memory space.

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

2012-02-01SwitchInst refactoring.Stepan Dyatkovskiy
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want. What was done: 1. Changed semantics of index inside the getCaseValue method: getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous. 2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned. 3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment. 4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst. 4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor. 4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor. Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149481 91177308-0d34-0410-b5e6-96231b3b80d8
