It is explicitly documented to have no effect on object formats where symbols
don't have sizes.

The internal shell was already threading around a 'cwd' parameter. We
just have to make it mutable so that we can update it as the test script
executes.
If the shell ever grows support for environment variable substitution,
we could also implement support for export.

Use the position of the subsequent symbol in the object file to infer
the size of it's predecessor. I hope to eventually remove whatever COFF
specific details from this little algorithm so that we can unify this
logic with what Mach-O does.

Do a better job classifying symbols. This increases the consistency
between the COFF handling code and the ELF side of things.

The -print-file-name option in llvm-nm is to precede each symbol
with the object file it came from. While code for the parsing of this
option and its aliases existed there was no code to implement it.

the specified section. This is same functionality as darwin’s nm(1) "-s" flag.
There is one FIXME in the code and I’m all ears to anyone that can help me
with that. This option takes exactly two strings and should be allowed
anywhere on the command line. Such that "llvm-nm -s __TEXT __text foo.o"
would work. But that does not as the CommandLine Library does not have a
way to make this work as far as I can tell. For now the "-s __TEXT __text"
has to be last on the command line.

symbol’s name. On darwin the -j flag is used (often in combinations
with other flags) to produce a complete list of symbol names which
than can then be reorder and used with ld(1)’s -order_file.

Tweak test cases that used llvm-nm with standard input to add a "-" to
indicate that and add a test case to check the default of a.out for llvm-nm.

for undefined symbols, so it matches what COFFObjectFile::getSymbolAddress
does. This allows llvm-nm to print spaces instead of 0’s for the value
of undefined symbols in Mach-O files.
To make this change other uses of MachOObjectFile::getSymbolAddress
are updated to handle when the Value is returned as UnknownAddressOrSize.
Which is needed to keep two of the ExecutionEngine tests working for example.

The implementation might be better to have a method is64Bit() in the class
SymbolicFile instead of having the static routine isSymbolList64Bit() in
llvm-nm.cpp . But this is very much in the sprit of isObject() and
getNMTypeChar() in llvm-nm.cpp that has a series of if else statements
based on the specific class of the SymbolicFile. I can update this if
folks would like.
Also the tests were updated to be explicit about checking the address for
64-bits or 32-bits from object files.

This reverts commit r205479.
It turns out that nm does use addresses, it is just that every reasonable
relocatable ELF object has sections with address 0. I have no idea if those
exist in reality, but it at least it shows that llvm-nm should use the name
address.
The added test was includes an unusual .o file with non 0 section addresses. I
created it by hacking ELFObjectWriter.cpp.
Really sorry for the churn.

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.

yaml2obj takes a textual description of an object file in YAML format
and outputs the binary equivalent. This greatly simplifies writing
tests that take binary object files as input.

- getSymbolOffset() renamed as getSymbolFileOffset()
- getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile.
- added getRelocationOffset()
- fixed MachOObjectFile::getSymbolSize()
- fixed MachOObjectFile::getSymbolSection()
- fixed MachOObjectFile::getSymbolOffset() for symbols without section data.
