* Object: Fix Mach-O relocation printing.Ahmed Bougacha2013-05-141-2/+3
| | | | | | | | | | There were two problems that made llvm-objdump -r crash: - for non-scattered relocations, the symbol/section index is actually in the (aptly named) symbolnum field. - sections are 1-indexed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181843 91177308-0d34-0410-b5e6-96231b3b80d8
* Change getRelocationAdditionalInfo to be ELF only.Rafael Espindola2013-05-092-11/+0
| | | | | | | It was only implemented for ELF where it collected the Addend, so this patch also renames it to getRelocationAddend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181502 91177308-0d34-0410-b5e6-96231b3b80d8
* This patch breaks up Wrap.h so that it does not have to include all of Filip Pizlo2013-05-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix Addend computation for non external relocations on Macho.Rafael Espindola2013-04-301-0/+10
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180790 91177308-0d34-0410-b5e6-96231b3b80d8
* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-292-2/+25
| | | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8
* Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.Rafael Espindola2013-04-263-452/+132
| | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180624 91177308-0d34-0410-b5e6-96231b3b80d8
* Use a pointer as the relocation iterator.Rafael Espindola2013-04-251-24/+29
| | | | | | | | Since the relocation iterator walks only the relocations in one section, we can just use a pointer and avoid fetching information about the section at every reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180262 91177308-0d34-0410-b5e6-96231b3b80d8
* Clarify getRelocationAddress x getRelocationOffset a bit.Rafael Espindola2013-04-252-17/+2
| | | | | | | | | | getRelocationAddress is for dynamic libraries and executables, getRelocationOffset for relocatable objects. Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a test of ELF's. llvm-readobj -r now prints the same values as readelf -r. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180259 91177308-0d34-0410-b5e6-96231b3b80d8
* Use pointers to iterate over symbols.Rafael Espindola2013-04-241-30/+36
| | | | | | | | While here, don't report a dummy symbol for relocations that don't have symbols. We used to says such relocations were for the first defined symbol, but now we return end_symbols(). The llvm-readobj output change agrees with otool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180214 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert r180189.Rafael Espindola2013-04-241-29/+24
| | | | | | | This should bring the ppc bots back. I will try to write a test that would have found the problem on a little endian system too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180194 91177308-0d34-0410-b5e6-96231b3b80d8

* Move C++ code out of the C headers and into either C++ headersEric Christopher2013-04-221-0/+39
| | | | | | | or the C++ files themselves. This enables people to use just a C compiler to interoperate with LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180063 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't read one command past the end.Rafael Espindola2013-04-191-2/+6
| | | | | | | | | Thanks to Evgeniy Stepanov for reporting this. It might be a good idea to add a command iterator abstraction to MachO.h, but this fixes the bug for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179848 91177308-0d34-0410-b5e6-96231b3b80d8
* At Jim Grosbach's request detemplate Object/MachO.h.Rafael Espindola2013-04-181-82/+1379
| | | | | | | We are still able to handle mixed endian objects by swapping one struct at a time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179778 91177308-0d34-0410-b5e6-96231b3b80d8
* Make the host endianness check an integer constant expression.Rafael Espindola2013-04-151-1/+1
| | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179527 91177308-0d34-0410-b5e6-96231b3b80d8

* Add 179294 back, but don't use bit fields so that it works on big endian hosts.Rafael Espindola2013-04-121-8/+44
| | | | | | | | | | | | | | Original message: Print more information about relocations.
