I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

Also corrected the name of the load command to not end in an ’S’ as well as corrected
the name of the MachO::linker_option_command struct and other places that had the
word option as plural which did not match the Mac OS X headers.

Add in definedness checks for shift operators, null checks when
pointers are assumed by the code to be non-null, and explicit
unreachables.

These methods are only used by MCJIT and are very specific to it. In fact, they
are also fairly specific to the fact that we have a dynamic linker of
relocatable objects.

Instead, walk the obj symbol list in parallel to find the GV. This shouldn't
change anything on ELF where global symbols are not mangled, but it is a step
toward supporting other object formats.
Gold itself is ELF only, but bfd ld supports COFF and the logic in the gold
plugin could be reused on lld.

Summary: Add rpath load command support in Mach-O object and update llvm-objdump to use it.

llvm-objdump printed out an error message for this off-by-one error,
but because it always exits with 0 whether or not it found an error,
the test (llvm-objdump/coff-many-relocs.test) succeeded.
I made llvm-objdump exit with EXIT_FAILURE when an error is found.

We can now use the ELF relocation .def files to create the mapping
of relocation numbers to names and avoid having to duplicate the
list of relocations.

It printed out base relocation table header as table entry.
This patch also makes llvm-readobj to not skip ABSOLUTE entries
becuase it was confusing.

We were a little lax in a few areas:
- We pretended that import libraries were like any old COFF file, they
are not. In fact, they aren't really COFF files at all, we should
probably grow some specialized functionality to handle them smarter.
- Our symbol iterators were more than happy to attempt to go past the
end of the symbol table if you had a symbol with a bad list of
auxiliary symbols.

In support of serializing executables, obj2yaml now records the virtual address
and size of sections. It also serializes whatever we strictly need from
the PE header, it expects that it can reconstitute everything else via
inference.
yaml2obj can reconstitute a fully linked executable.
In order to get executables correctly serialized/deserialized, other
bugs were fixed as a circumstance. We now properly respect file and
section alignments. We also avoid writing out string tables unless they
are strictly necessary.

Split getObject's smarts into checkOffset, use this to replace the
handwritten check in getSectionContents. Similarly, replace checks in
section_rel_begin/section_rel_end with getNumberOfRelocations.
No functionality change intended.

lib/Object is supposed to be robust to malformed object files. Don't
assert if we don't have a symbol table. I'll try to come up with a test
case later.
llvm-svn: 221870
getObject didn't consider the case where a pointer came before the start
of the object file. No test is included, trying to come up with
something reasonable.
llvm-svn: 221868
For historical reasons archives on mach-o have two possible names for the
file containing the table of contents for the archive: "__.SYMDEF SORTED"
and "__.SYMDEF". But the libObject archive reader only supported the former.
This patch fixes llvm::object::Archive to support both names.
llvm-svn: 221747
The ELF symbol `st_other` field might contain additional flags besides
visibility ones. This patch implements support for some MIPS specific
flags.

mingw lies about the size of a function's AuxFunctionDefinition. Ignore
the field and rely on our heuristic to determine the symbol's size.
llvm-svn: 221485
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.

To do this, change the representation of lazy loaded functions.
The previous representation cannot differentiate between a function whose body
has been removed and one whose body hasn't been read from the .bc file. That
means that in order to drop a function, the entire body had to be read.
