2012-05-18Refactor data-in-code annotations.Jim Grosbach
Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 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.

2012-04-12This patch improves the MCJIT runtime dynamic loader by adding new handlingPreston Gurd
of zero-initialized sections, virtual sections and common symbols and preventing the loading of sections which are not required for execution such as debug information. Patch by Andy Kaylor! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154610 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01[Object]David Meyer
* Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile. * Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable. * Implement this new interface completely for ELF, leave stubs for COFF and MachO. * Add 'llvm-readobj' tool for dumping ObjectFile information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151785 91177308-0d34-0410-b5e6-96231b3b80d8
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

2012-02-12Expose 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
