This patch implements the Darwin dwarfdump option --recurse-depth=<N>,
which limits the recursion depth when selectively printing DIEs at an
offset.

Inputs should be placed local to the test (or possibly in a common
parent? I think we do that in some places - but the only common parent
between these two directories is 'test' which seems a bit overly broad).

This is the first of many commits that enable selectively dumping just
one record from the debug info.
This reapplies r313412 with some extra qualification to appease GCC and MSVC.

This patches renames "brief" to "verbose" in de DIDumpOptions and
inverts the logic to match the new behavior where brief is the default.
Changing the default value uncovered some bugs related to the
DIDumpOptions not being propagated and have been fixed as well.

As discussed on llvm-dev in
http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html
this changes the command line interface of llvm-dwarfdump to match the
one used by the dwarfdump utility shipping on macOS. In addition to
being shorter to type this format also has the advantage of allowing
more than one section to be specified at the same time.
In a nutshell, with this change
$ llvm-dwarfdump --debug-dump=info
$ llvm-dwarfdump --debug-dump=apple-objc
becomes
$ dwarfdump --debug-info --apple-objc

This patch changes the default behavior in brief mode to only show the
debug_info section. This is undoubtedly the most popular and likely the
one you'd want in brief mode.
Non-brief mode behavior is not affected and still defaults to all.

This patch hides the .debug_str offset and DIE reference offsets into
the CU when llvm-dwarfdump is invoked with -brief.

SUMMARY
This patch adds a verification check on the abbreviation declarations in the .debug_abbrev section.
The check makes sure that no abbreviation declaration has more than one attributes with the same name.

Summary:
This patch modifies the handleDebugInfo() function so that we verify the contents of each unit
in the .debug_info section only if its header has been successfully verified.
This change will allow for more/different verification checks depending on the type of the unit since from
dwarf5, the .debug_info section may consist of different types of units.

This patch adds verification checks for the unit header chain in the .debug_info section.
Specifically, for each unit in the .debug_info section, the verifier checks that:
The unit length is valid (i.e. the unit can actually fit in the .debug_info section)
The dwarf version of the unit is valid
The address size is valid (4 or 8)
The unit type (if the unit is in dwarf5) is valid
The debug_abbrev_offset is valid
llvm-svn: 307975
This patch verifies the number of atoms, the validity of the form for each atom, as well as the validity of the
hashdata. For hashdata, we're verifying that the hashdata offset is correct and that the offset in the .debug_info for
each DIE in the hashdata is also valid.
llvm-svn: 306735
The verifier should not output any message in such a case.
Added test case with no .apple_name section in the file to verify new functionality.
Made existing test case more specific.
llvm-svn: 305597
This patch adds code which verifies that each bucket in the .apple_names
accelerator table is either empty or has a valid hash index.

This patch introduces a new command line option, called brief, to
llvm-dwarfdump. When -brief is used, the attribute forms for the
.debug_info section will not be emitted to output.

For biendian targets like ARM and AArch64, it is useful to have the
output of the llvm-dwarfdump and llvm-objdump report the endianness
used when the object files were generated.
Patch by Charlie Turner.
llvm-svn: 218408
This change fixes the ARM and AArch64 relocation visitors in
RelocVisitor. They were unconditionally assuming the object data are
little-endian. Tests have been added to ensure that the
llvm-dwarfdump utility does not crash when processing big-endian
object files.
