* [SystemZ] Add MCJIT supportRichard Sandiford2013-05-034-0/+113
| | | | | | | | Another step towards reinstating the SystemZ backend. I'll commit the configure changes separately (TARGET_HAS_JIT etc.), then commit a patch to enable the MCJIT tests on SystemZ. llvm-svn: 181015
* Fix Addend computation for non external relocations on Macho.Rafael Espindola2013-04-301-28/+10
| | | | llvm-svn: 180790
* Collect the Addend for external relocs.Rafael Espindola2013-04-301-5/+12
| | | | | | | This fixes 2013-04-04-RelocAddend.ll. We don't have a testcase for non external relocs with an Addend. I will try to write one. llvm-svn: 180767
* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-294-18/+2
| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). llvm-svn: 180736
* Rationalize what is public in RuntimeDyldMachO and RuntimeDyldELF.Rafael Espindola2013-04-292-25/+18
| | | | | | | | The implemented RuntimeDyldImpl interface is public. Everything else is private. Since these classes are not inherited from (yet), there is no need to have protected members. llvm-svn: 180733

* Use a RelocationRef instead of a relocation_iterator.Rafael Espindola2013-04-296-13/+13
| | | | | | No functionality change. llvm-svn: 180723
* Propagate relocation info to resolveRelocation.Rafael Espindola2013-04-296-41/+58
| | | | | | This gets most of the MCJITs tests passing with MachO. llvm-svn: 180716
* Replace ObjRelocationInfo with relocation_iterator.Rafael Espindola2013-04-296-65/+59
| | | | | | | | | | | For MachO we need information that is not represented in ObjRelocationInfo. Instead of copying the bits we think are needed from a relocation_iterator, just pass the relocation_iterator down to the format specific functions. No functionality change yet as we still drop the information once processRelocationRef returns. llvm-svn: 180711
* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-261-1/+1
| | | | | | | | | | | | | | | | | | | | | For Mach-O there were 2 implementations for parsing object files. A standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which implements the generic interface in llvm/Object/ObjectFile.h. This patch adds the missing features to MachO.h, moves macho-dump to use MachO.h and removes ObjectFile.h. In addition to making sure that check-all is clean, I checked that the new version produces exactly the same output in all Mach-O files in a llvm+clang build directory (including executables and shared libraries). To test the performance, I ran macho-dump over all the files in a llvm+clang build directory again, but this time redirecting the output to /dev/null. Both the old and new versions take about 4.6 seconds (2.5 user) to finish. llvm-svn: 180624
* Two small cleanups for ELF's templates.Rafael Espindola2013-04-171-1/+1
| | | | | | | | | | * We only ever specialize these templates with an instantiation of ELFType, so we don't need a template template. * Replace LLVM_ELF_COMMA with just passing the individual parameters to the macro. This requires a second macro for when we only have ELFT, but that is still a small win. llvm-svn: 179726
* Make the host endianness check an integer constant expression.Rafael Espindola2013-04-151-3/+3
| | | | | | | | | | | | | | | I will remove the isBigEndianHost function once I update clang. 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
* Respect Addend when processing MCJIT relocations to local/global symbols.Ulrich Weigand2013-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the RuntimeDyldELF::processRelocationRef routine finds the target symbol of a relocation in the local or global symbol table, it performs a section-relative relocation: Value.SectionID = lsi->second.first; Value.Addend = lsi->second.second; At this point, however, any Addend that might have been specified in the original relocation record is lost. This is somewhat difficult to trigger for relocations within the code section since they usually do not contain non-zero Addends (when built with the default JIT code model, in any case). However, the problem can be reliably triggered by a relocation within the data section caused by code like: int test[2] = { -1, 0 }; int *p = &test[1]; The initializer of "p" will need a relocation to "test + 4". On platforms using RelA relocations this means an Addend of 4 is required. Current code ignores this addend when processing the relocation, resulting in incorrect execution. Fixed by taking the Addend into account when processing relocations to symbols found in the local or global symbol table. Tested on x86_64-linux and powerpc64-linux. llvm-svn: 178869

* [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. llvm-svn: 172515
* 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. llvm-svn: 171979

* 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. llvm-svn: 171506

* 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 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.

* 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
