* Don't link with the archive library programs that don't use it.Rafael Espindola2013-06-17

* readobj: Dump PE/COFF optional records.Rui Ueyama2013-06-12
| | | | | | | | | | | | These records are mandatory for executables and are used by the loader. Reviewers: rafael CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D939 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183852 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
* Introduce convenience typedefs for the 4 ELF object types.Rafael Espindola2013-05-09
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181509 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
* Revert r181009.Amara Emerson2013-05-03
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181079 91177308-0d34-0410-b5e6-96231b3b80d8
* Add support for reading ARM ELF build attributes.Amara Emerson2013-05-03
| | | | | | | | | | | | Build attribute sections can now be read if they exist via ELFObjectFile, and the llvm-readobj tool has been extended with an option to dump this information if requested. Regression tests are also included which exercise these features. Also update the docs with a fixed ARM ABI link and a new link to the Addenda which provides the build attributes specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181009 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

* At Jim Grosbach's request detemplate Object/MachO.h.Rafael Espindola2013-04-18
| | | | | | | 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
* Remove getters now that we can specialize structs on the host endianness.Rafael Espindola2013-04-15

* Finish templating MachObjectFile over endianness.Rafael Espindola2013-04-13
| | | | | | | We are now able to handle big endian macho files in llvm-readobject. Thanks to David Fang for providing the object files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179440 91177308-0d34-0410-b5e6-96231b3b80d8

* Add -expand-relocs to llvm-readobjNico Rieck2013-04-12

* 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

| | | | | | | For now it is templated only on being 64 or 32 bits. I will add little/big endian next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179097 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't fetch pointers from a InMemoryStruct.Rafael Espindola2013-04-05
| | | | | | | | InMemoryStruct is extremely dangerous as it returns data from an internal buffer when the endiannes doesn't match. This should fix the tests on big endian hosts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178875 91177308-0d34-0410-b5e6-96231b3b80d8
* Implements low-level object file format specific output for COFF andEric Christopher2013-04-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ELF with support for: - File headers - Section headers + data - Relocations - Symbols - Unwind data (only COFF/Win64) The output format follows a few rules: - Values are almost always output one per line (as elf-dump/coff-dump already do). - Many values are translated to something readable (like enum names), with the raw value in parentheses. - Hex numbers are output in uppercase, prefixed with "0x". - Flags are sorted alphabetically. - Lists and groups are always delimited. Example output: ---------- snip ---------- Sections [ Section { Index: 1 Name: .text (5) Type: SHT_PROGBITS (0x1) Flags [ (0x6) SHF_ALLOC (0x2) SHF_EXECINSTR (0x4) ] Address: 0x0 Offset: 0x40 Size: 33 Link: 0 Info: 0 AddressAlignment: 16 EntrySize: 0 Relocations [ 0x6 R_386_32 .rodata.str1.1 0x0 0xB R_386_PC32 puts 0x0 0x12 R_386_32 .rodata.str1.1 0x0 0x17 R_386_PC32 puts 0x0 ] SectionData ( 0000: 83EC04C7 04240000 0000E8FC FFFFFFC7 |.....$..........| 0010: 04240600 0000E8FC FFFFFF31 C083C404 |.$.........1....| 0020: C3 |.| ) } ] ---------- snip ---------- Relocations and symbols can be output standalone or together with the section header as displayed in the example. This feature set supports all tests in test/MC/COFF and test/MC/ELF (and I suspect all additional tests using elf-dump), making elf-dump and coff-dump deprecated.
