* Handle relocations that don't point to symbols.Rafael Espindola2013-06-051-4/+3
| | | | | | | | 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. llvm-svn: 183284
* Use pointers to iterate over symbols.Rafael Espindola2013-04-241-1/+3
| | | | | | | | 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. llvm-svn: 180214
* llvm-readobj: Do not print NULL StringRefsNico Rieck2013-04-221-5/+4
| | | | llvm-svn: 180005
* At Jim Grosbach's request detemplate Object/MachO.h.Rafael Espindola2013-04-181-75/+58
| | | | | | | We are still able to handle mixed endian objects by swapping one struct at a time. llvm-svn: 179778
* Remove getters now that we can specialize structs on the host endianness.Rafael Espindola2013-04-151-3/+3
| | | | llvm-svn: 179534
* Finish templating MachObjectFile over endianness.Rafael Espindola2013-04-131-52/+80
| | | | | | | We are now able to handle big endian macho files in llvm-readobject. Thanks to David Fang for providing the object files. llvm-svn: 179440
* Add -expand-relocs to llvm-readobjNico Rieck2013-04-121-12/+26
| | | | | | | | | | | | | | This option expands shown relocations from single line to a dictionary format: Relocation { Offset: 0x4 Type: R_386_32 (1) Symbol: sym Info: 0x0 } llvm-svn: 179359
* Add 179294 back, but don't use bit fields so that it works on big endian hosts.Rafael Espindola2013-04-121-4/+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. llvm-svn: 179345
* Revert my last two commits while I debug what is wrong in a big endian host.Rafael Espindola2013-04-111-12/+4

* Template MachOObjectFile over endianness too.Rafael Espindola2013-04-101-8/+8
| | | | llvm-svn: 179179
* Convert MachOObjectFile to a template.Rafael Espindola2013-04-091-13/+15
| | | | | | | For now it is templated only on being 64 or 32 bits. I will add little/big endian next. llvm-svn: 179097
* Template the MachO types over the word size.Rafael Espindola2013-04-081-5/+6
| | | | llvm-svn: 179051
* Remove two uses of getObject.Rafael Espindola2013-04-071-13/+2
| | | | llvm-svn: 178985
* Remove usage of InMemoryStruct in getSymbol.Rafael Espindola2013-04-071-26/+6
| | | | llvm-svn: 178984
* Remove a use of InMemoryStruct in llvm-readobj.Rafael Espindola2013-04-071-9/+6
| | | | llvm-svn: 178981
* Make getObject const. Remove a const_cast.Rafael Espindola2013-04-071-1/+1
| | | | llvm-svn: 178980
* Don't fetch pointers from a InMemoryStruct.Rafael Espindola2013-04-051-15/+8
| | | | | | | | 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. llvm-svn: 178875
* Implements low-level object file format specific output for COFF andEric Christopher2013-04-031-0/+438
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.
