David Majnemer 51ff559500 Object, COFF: Infer symbol sizes from adjacent symbols
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.

David Majnemer c7d7c6fb3a Object, COFF: Cleanup symbol type code, improve binutils compatibility
Do a better job classifying symbols.  This increases the consistency
between the COFF handling code and the ELF side of things.

Kevin Enderby 49b4f53cad Tweak llvm-nm’s -undefined-only (aka -u) printing for Mach-O files
to just print the symbol name.  So it matches darwin’s nm(1) -u option.

Kevin Enderby 08e1bbd645 Add an implementation for llvm-nm’s -print-file-name option (aka -o and -A).
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.

Kevin Enderby 77b968e1e1 Add the "-x" flag to llvm-nm for Mach-O files that prints the fields of a symbol in hex.
(generally use for debugging the tools).  This is same functionality as darwin’s
nm(1) "-x" flag.

Kevin Enderby fe6ad97ca8 Add the "-s" flag to llvm-nm for Mach-O files that prints symbols only in
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.

Kevin Enderby 0fd8aac5da Add the -just-symbol-name (aka -j) flag to llvm-nm to just print the
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.

Kevin Enderby acaaf903e8 Add the -U flag to llvm-nm as an alias to -defined-only
as darwin’s nm(1) uses -U for this functionality.

Kevin Enderby 4fc2edb023 Change the default input for llvm-nm to be a.out instead of standard input
to match llvm-size and other UNIX systems for their nm(1).

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.

Kevin Enderby 1e1b992ad7 Fix the output of llvm-nm for Mach-O files to use the characters ‘d’ and ‘b’ for
data and bss symbols instead of the generic ’s’ for a symbol in a section.

Kevin Enderby 1b985af0ba Update MachOObjectFile::getSymbolAddress so it returns UnknownAddressOrSize
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.

Kevin Enderby 6abc2e58ac Fix llvm-nm to print the full 64-bit address for symbols in 64-bit object files.
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.

Rafael Espindola b4865d698b Revert "Fix a nomenclature error in llvm-nm."
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.

Michael J. Spencer 1ffd9de4f1 Add yaml2obj. A utility to convert YAML to binaries.
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.

Danil Malyshev cbe72fc959 Fixed ObjectFile functions:
- 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.
