* Make the host endianness check an integer constant expression.Rafael Espindola2013-04-151-3/+3

The ifdef logic is designed to * not use configure/cmake to avoid breaking -arch i686 -arch ppc. * default to little endian * be as small as possible It looks like sys/endian.h is the preferred header on most modern BSD systems, but it is better to change this in a followup patch as machine/endian.h is available on FreeBSD, OpenBSD, NetBSD and OS X. llvm-svn: 179527

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

* RuntimeDyld cleanup:Eli Bendersky2012-05-011-10/+13
| | | | | | | | | | | - 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. Restricts it for a single goal and may serve as a step for eventual removal. llvm-svn: 155908
* RuntimeDyld code cleanup:Eli Bendersky2012-05-011-8/+8
| | | | | | | | | - 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

| | | | | | | | | 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. llvm-svn: 155819

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. Patch by Andy Kaylor! llvm-svn: 154868

* Re-factored RuntimeDyLd:Danil Malyshev2012-03-301-21/+147
| | | | | | | | | | | | | | | 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

* Revert a series of commits to MCJIT to get the build working in CMakeChandler Carruth2012-03-221-147/+21
| | | | | | | | | | | | | | | (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

* MCJIT support for non-function sections.Jim Grosbach2012-01-161-30/+55
| | | | | | | | | | | | | | | | 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. llvm-svn: 148258
