802fe9340d Use pointers to iterate over symbols.
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.

fd7aa38e30 At Jim Grosbach's request detemplate Object/MachO.h.
We are still able to handle mixed endian objects by swapping one struct at a
time.

da2a2372c6 Finish templating MachObjectFile over endianness.
We are now able to handle big endian macho files in llvm-readobject. Thanks to
David Fang for providing the object files.

8ed205f0a3 Add extensive relocation tests for llvm-readobj
This test ensures that relocation type names returned by libObject match
the raw relocation type value.

e292347503 Add 179294 back, but don't use bit fields so that it works on big endian hosts.
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.

f16c2bb320 Don't fetch pointers from a InMemoryStruct.
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.

3f26127c0b Loosen this test.
Looks like there is a big endian/little endian problem here. Loosen the
test to try to get the bots green while llvm builds on a ppc qemu vm.

The failure was in http://lab.llvm.org:8011/builders/clang-ppc64-elf-linux2/

76e70f340c 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.

Patch by Nico Rieck!

00fb9c429e PR10867. lit would interpret
RUN: a
  RUN: b || true

as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode.
Everyone seems to (quite reasonably) write tests assuming the Tcl behavior,
so use that in sh mode too.

eef7b6219e Add dump of Win64 EH unwind data.
The new command line option -unwind-info dumps the Win64 EH unwind
data to the console. This is a nice feature if you need to debug
generated EH data (e.g. from LLVM). Includes a test case.

Initial patch by João Matos, extensions and rework by Kai Nacke.
