* Object: Fix Mach-O relocation printing.Ahmed Bougacha2013-05-141-0/+35
| | | | | | | | | | 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 Espindola2013-05-091-2/+2
| | | | | | | 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
* Split Alignment out of the Section Characteristics.Rafael Espindola2013-05-062-4/+8
| | | | | | | | The alignment is just a byte in the middle of Characteristics, not an independent flag. Making it an independent field in the yaml representation makes it more yamlio friendly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181243 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support for reading ARM ELF build attributes.Amara Emerson2013-05-033-0/+46
| | | | | | | | | | | | 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 Espindola2013-04-252-0/+18
| | | | | | | | | | 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

* Don't read one command past the end.Rafael Espindola2013-04-192-0/+4
| | | | | | | | | 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

| | | | | | | | It had been dropped during the switch to yaml::IO. Also add a test going from yaml2obj to llvm-readobj. It can be extended as we add more fields/formats to yaml2obj. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178786 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement the "mips endian" for r_info.Rafael Espindola2013-04-032-0/+7
| | | | | | | | Normally r_info is just a 32 of 64 bit number matching the endian of the rest of the file. Unfortunately, mips 64 bit little endian is special: The top 32 bits are a little endian number and the following 32 are a big endian one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178694 91177308-0d34-0410-b5e6-96231b3b80d8
* Implements low-level object file format specific output for COFF andEric Christopher2013-04-032-89/+347
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
