* move getSymbolNMTypeChar to the one program that needs it: nm.Rafael Espindola2013-11-02

* Fix llvm-nm to mach OS X's nm on some tests.Rafael Espindola2013-11-02
| | | | | | | There is still a long way to go for llvm-nm, but at least we now match nm's letter output in the cases we test for. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193912 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | Object/MachOFormat.h over to Support/MachO.h." This reverts commits r189319 and r189315. r189315 broke some tests on what I believe are big-endian platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189321 91177308-0d34-0410-b5e6-96231b3b80d8

* Support/MachO: Add a bunch of defines.Charles Davis2013-08-27
| | | | | | | | Right now we have two headers for the Mach-O format. I'd like to get rid of one. Since the other object formats are all in Support, I chose to keep the Mach-O header in Support, and discard the other one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189314 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach llvm-objdump with the -macho parser how to use the data in code tableKevin Enderby2013-06-06
| | | | | | | | | | | | | | | | from the LC_DATA_IN_CODE load command. And when disassembling print the data in code formatted for the kind of data it and not disassemble those bytes. I added the format specific functionality to the derived class MachOObjectFile since these tables only appears in Mach-O object files. This is my first attempt to modify the libObject stuff so if folks have better suggestions how to fit this in or suggestions on the implementation please let me know. rdar://11791371 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183424 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle relocations that don't point to symbols.Rafael Espindola2013-06-05
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj ELF's dumper to handle relocatios without symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183284 91177308-0d34-0410-b5e6-96231b3b80d8
* Object: Fix Mach-O relocation printing.Ahmed Bougacha2013-05-14
| | | | | | | | | | 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 Espindola2013-05-09
| | | | | | | 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
* Fix Addend computation for non external relocations on Macho.Rafael Espindola2013-04-30

* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-29
| | | | | | | | | | | | | 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 Espindola2013-04-26
| | | | | | | | | | | | | | | | | | | | | 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 Espindola2013-04-25
| | | | | | | | 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 Espindola2013-04-25
| | | | | | | | | | 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 Espindola2013-04-24
| | | | | | | | 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 Espindola2013-04-24
| | | | | | | 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

* Don't read one command past the end.Rafael Espindola2013-04-19
| | | | | | | | | 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

* Add 179294 back, but don't use bit fields so that it works on big endian hosts.Rafael Espindola2013-04-12
| | | | | | | | | | | | | | Original message: Print more information about relocations. With this patch llvm-readobj now prints if a relocation is pcrel, its length, if it is extern and if it is scattered. It also refactors the code a bit to use bit fields instead of shifts and masks all over the place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179345 91177308-0d34-0410-b5e6-96231b3b80d8
