Fix a pair of array index checks.

Patch by Marius Wachtler.

llvm-svn: 196560

move getSymbolNMTypeChar to the one program that needs it: nm.

llvm-svn: 193933

Fix llvm-nm to mach OS X's nm on some tests.

There is still a long way to go for llvm-nm, but at least we now match
nm's letter output in the cases we test for.

Object/COFF: Rename getXXX{Begin,End} -> xxx_{begin,end}.

It is mentioned in the LLVM coding standard that _begin() and _end() suffixes
should be used.

This reverts commits r189319 and r189315. r189315 broke some tests on what I
believe are big-endian platforms.

Teach llvm-objdump with the -macho parser how to use the data in code table
from the LC_DATA_IN_CODE load command. And when disassembling print
the data in code formatted for the kind of data it and not disassemble those
bytes.

I added the format specific functionality to the derived class MachOObjectFile
since these tables only appears in Mach-O object files. This is my first
attempt to modify the libObject stuff so if folks have better suggestions
how to fit this in or suggestions on the implementation please let me know.

patch also renames it to getRelocationAddend.

Add getSymbolAlignment to the ObjectFile interface.

For regular object files this is only meaningful for common symbols. An object
file format with direct support for atoms should be able to provide alignment
information for all symbols.

This replaces getCommonSymbolAlignment and fixes
test-common-symbols-alignment.ll on darwin. This also includes a fix to
MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common
(already tested by existing mcjit tests now that it is used).

Use llvm/Object/MachO.h in macho-dumper. Drop the old macho parser.

For Mach-O there were 2 implementations for parsing object files. A
standalone llvm/Object/MachOObject.h and llvm/Object/MachO.h which
implements the generic interface in llvm/Object/ObjectFile.h.

This patch adds the missing features to MachO.h, moves macho-dump to
use MachO.h and removes ObjectFile.h.

In addition to making sure that check-all is clean, I checked that the
new version produces exactly the same output in all Mach-O files in a
llvm+clang build directory (including executables and shared
libraries).

To test the performance, I ran macho-dump over all the files in a
llvm+clang build directory again, but this time redirecting the output
to /dev/null. Both the old and new versions take about 4.6 seconds
(2.5 user) to finish.

This should bring the ppc bots back. I will try to write a test that would
have found the problem on a little endian system too.
