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.

ELF: Relocations [
Change how we iterate over relocations on ELF. For COFF and MachO, sections semantically have relocations that apply to them. That is not the case on ELF. In relocatable objects (.o), a section with relocations in ELF has offsets to another section where the relocations should be applied. In dynamic objects and executables, relocations don't have an offset, they have a virtual address. The section sh_info may or may not point to another section, but that is not actually used for resolving the relocations. This patch exposes that in the ObjectFile API. It has the following advantages: * Most (all?) clients can handle this more efficiently. They will normally walk all relocations, so doing an effort to iterate in a particular order doesn't save time. * llvm-readobj now prints relocations in the same way the native readelf does. * probably most important, relocations that don't point to any section are now visible. This is the case of relocations in the rela.dyn section. See the updated relocation-executable.test for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182908 91177308-0d34-0410-b5e6-96231b3b80d8

llvm-readobj: fix MachO relocatoin printing a bit. There were two issues here: 1. At the very least, scattered relocations cannot use the same code to determine the corresponding symbol being referred to. For some reason we pretend there is no symbol, even when one actually exists in the symtab, so to match this behaviour getRelocationSymbol should simply return symbols_end for scattered relocations. 2. Printing "-" when we can't get a symbol (including the scattered case, but not exclusively), isn't that helpful. In both cases there *is* interesting information in that field, so we should print it.

llvm-readobj: fix MachO relocatoin printing a bit. There were two issues here: 1. At the very least, scattered relocations cannot use the same code to determine the corresponding symbol being referred to. For some reason we pretend there is no symbol, even when one actually exists in the symtab, so to match this behaviour getRelocationSymbol should simply return symbols_end for scattered relocations. 2. Printing "-" when we can't get a symbol (including the scattered case, but not exclusively), isn't that helpful. In both cases there *is* interesting information in that field, so we should print it. As hex will do. Small part of rdar://problem/17553104 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212332 91177308-0d34-0410-b5e6-96231b3b80d8
