We were quite happy to read past the end of the valid section data when
disassembling. Instead we entirely skip stub dylibs, and tell the user what's
happened if their section only has partial data.

with the -macho and -universal-headers flags.
Just a follow on to r273207, I missed updating the printing of the fat magic
number when the universal file is a 64-bit universal file.

It was printing out nothing in this case.
llvm-objdump tries to disassemble sections a symbol at a time. In the case of a
fully stripped Mach-O executable the only symbol remaining in the (__TEXT,__text)
section is the special linker defined symbol __mh_execute_header . This
symbol is special in that while it is N_SECT symbol in the (__TEXT,__text)
its address is before the start of the (__TEXT,__text). It’s address is the
start of the __TEXT segment which is where the mach header is statically
linked. So the code in DisassembleMachO() needs to deal with this case specially.

In executable and shared object ELF files, relocations in the file contain the final virtual address rather than section offset so this is adjusted to display section offset.

Most linked executables do not have a symbol table in COFF.
However, it is pretty typical to have some export entries. Use those
entries to inform the disassembler about potential function definitions
and call targets.

that caused aborts. This was because of the characters of the ‘Size’ field in
the archive header did not contain decimal characters.

The COFFSymbolRef::isFunctionDefinition() function tests for several conditions
that are not related to whether a symbol is a function, but rather whether
the symbol meets the requirements for a function definition auxiliary record,
which excludes certain symbols such as internal functions and undefined
references. The test we need to determine the symbol type is much simpler:
we only need to compare the complex type against IMAGE_SYM_DTYPE_FUNCTION.

print the Objective-C runtime meta data for Mach-O files.
There are three types of Objective-C runtime meta data, Objc2 64-bit,
Objc2 32-bit and Objc1 32-bit. This prints the first of these types. The
changes to print the others will follow next.

segname,sectname to specify a Mach-O section to print. The printing is based on
the section type or section attributes.
The printing of the module initialization and termination section types is printed
with this change. Printing of other section types will be added next.

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.

with fixes. Includes the move of tests for llvm-objdump for universal files to an X86
directory. And the fix where it was failing on linux Rafael tracked down with asan.
I had both Jim Grosbach and Adam Hemet look over the second fix since I could not
set up asan to reproduce with the old version but not with the fix.
