Implements low-level object file format specific output for COFF and 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.

Don't hide the first ELF symbol. The first symbol on ELF is dummy, but it has a defined content and readelf normally displays it. With this change llvm-readobj also displays it and we can check that llvm-mc output is correct according to the standard. llvm-svn: 183337
