2012-02-29[Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ↵David Meyer
ST_Undefined. Implement these completely for ELF. Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type is unknown, not that the symbol is undefined. (For that, use ST_Undefined). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151696 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-27Remove duplicate copy of Object/ELF.h that somehow managed to get in.Michael J. Spencer
Patch by David Meyer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151575 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. This patch was reviewed by Michael Spencer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150327 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-22Basic runtime dynamic loading capabilities added to ELFObjectFile, implementedEli Bendersky
in a subclass named DyldELFObject. This class supports rebasing the object file it represents by re-mapping section addresses to the actual memory addresses the object was placed in. This is required for MC-JIT implementation on ELF with debugging support. Patch reviewed on llvm-commits. Developed together with Ashok Thirumurthi and Andrew Kaylor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148653 91177308-0d34-0410-b5e6-96231b3b80d8
