* [Object][ELF] Simplify ELFObjectFile by using ELFType.Michael J. Spencer2013-01-151-41/+41
| | | | | | | | | | | | | This simplifies the usage and implementation of ELFObjectFile by using ELFType to replace: <endianness target_endianness, std::size_t max_alignment, bool is64Bits> This does complicate the base ELF types as they must now use template template parameters to partially specialize for the 32 and 64bit cases. However these are only defined once. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172515 91177308-0d34-0410-b5e6-96231b3b80d8
* PowerPC: EH adjustmentsAdhemerval Zanella2013-01-091-1/+8
| | | | | | | | | | | This patch adjust the r171506 to make all DWARF enconding pc-relative for PPC64. It also adds the R_PPC64_REL32 relocation handling in MCJIT (since the eh_frame will not generate PIC-relative relocation) and also adds the emission of stubs created by the TTypeEncoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171979 91177308-0d34-0410-b5e6-96231b3b80d8

* PowerPC: Fix eh_frame relocation for PIC Adhemerval Zanella2013-01-041-0/+6
| | | | | | | | | | | This patch fixes the PPC eh_frame definitions for the personality and frame unwinding for PIC objects. It makes PIC build correctly creates relative relocations in the '.rela.eh_frame' segments and thus avoiding a text relocation that generates a DT_TEXTREL segments in link phase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171506 91177308-0d34-0410-b5e6-96231b3b80d8

* 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. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | The SectionMemoryManager now supports (and requires) applying section-specific page permissions.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167304 91177308-0d34-0410-b5e6-96231b3b80d8
