* RuntimeDyld: Fix up r169178. MSVC doesn't like "or".NAKAMURA Takumi2012-12-042-2/+2
| | | | llvm-svn: 169183
* Runtime dynamic linker for MCJIT should support MIPS BigEndian architecture.Akira Hatanaka2012-12-033-3/+4
| | | | | | | | | This small change adds support for that. It will make all MCJIT tests pass in make-check on BigEndian platforms. Patch by Petar Jovanovic. llvm-svn: 169178
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-034-13/+14
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. 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. =] llvm-svn: 169131
* Moving SectionMemoryManager to MCJIT to avoid cross dependency between JIT ↵Andrew Kaylor2012-11-282-227/+0

* Moving SectionMemoryManager into RuntimeDyld and adding unit tests for it.Andrew Kaylor2012-11-272-0/+227
| | | | | | | | The SectionMemoryManager now supports (and requires) applying section-specific page permissions. Clients using this memory manager must call either MCJIT::finalizeObject() or SectionMemoryManager::applyPermissions() before executing JITed code. See r168718 for changes from the previous implementation. llvm-svn: 168721

* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-051-7/+9
| | | | | | 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. llvm-svn: 167400
* Change resolveRelocation parameters so the relocations can find placeholder ↵Andrew Kaylor2012-11-026-77/+99
| | | | | | | | values in the original object buffer. Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location. In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer. This patch changes the parameters passed to resolveRelocations to accommodate this need. llvm-svn: 167304

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds initial support for MCJIT for PPC64-elf-abi.

* RuntimeDyld cleanup:Eli Bendersky2012-05-014-65/+77
| | | | | | | | | | | - 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.

| | | | | | | | | - 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 llvm-svn: 155898

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.

* Re-factored RuntimeDyLd:Danil Malyshev2012-03-306-1010/+751
| | | | | | | | | | | | | | | 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. llvm-svn: 153754

| | | | | | | | | | | | | | | (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. llvm-svn: 153241
