Commit 04f096fb9e25 ("Move the xc16x target to the obsolete list") moved
the architecture from the "obsolete but still available" to the
"obsolete / support removed" list in config.bfd, making the architecture
impossible to enable (except maybe via "enable everything" options").
Note that I didn't touch */po/*.po{,t} on the assumption that these
would be updated by some (half)automatic means.

For clang compiled objects with dwarf-5, location list offset address dump

git commit 202be274a4 went a little wild in removing trailing spaces

This commit adds the _option_ of having disassembler output syntax
highlighted in objdump. This option is _off_ by default. The new
command line options are:
--disassembler-color=off # The default.
--disassembler-color=color
--disassembler-color=extended-color
I have implemented two colour modes, using the same option names as we
use of --visualize-jumps, a basic 8-color mode ("color"), and an
extended 8bit color mode ("extended-color").
The syntax highlighting requires that each targets disassembler be
updated; each time the disassembler produces some output we now pass
through an additional parameter indicating what style should be
applied to the text.
As updating all target disassemblers is a large task, the old API is
maintained. And so, a user of the disassembler (i.e. objdump, gdb)
must provide two functions, the current non-styled print function, and
a new, styled print function.
I don't currently have a plan for converting every single target
disassembler, my hope is that interested folk will update the
disassemblers they are interested in. But it is possible some might
never get updated.
In this initial series I intend to convert the RISC-V disassembler
completely, and also do a partial conversion of the x86 disassembler.
Hopefully having the x86 disassembler at least partial converted will
allow more people to try this out easily and provide feedback.
In this commit I have focused on objdump. The changes to GDB at this
point are the bare minimum required to get things compiling, GDB makes
no use of the styling information to provide any colors, that will
come later, if this commit is accepted.
This first commit in the series doesn't convert any target
disassemblers at all (the next two commits will update some targets),
so after this commit, the only color you will see in the disassembler
output, is that produced from objdump itself, e.g. from
objdump_print_addr_with_sym, where we print an address and a symbol
name, these are now printed with styling information, and so will have
colors applied (if the option is on).
Finally, my ability to pick "good" colors is ... well, terrible. I'm
in no way committed to the colors I've picked here, so I encourage
people to suggest new colors, or wait for this commit to land, and
then patch the choice of colors.
I do have an idea about using possibly an environment variable to
allow the objdump colors to be customised, but I haven't done anything
like that in this commit, the color choices are just fixed in the code
for now.

My previous nm patch handled all cases but one -- if the user set NM in
the environment to a path which contained an option, libtool's nm
detection tries to run nm against a copy of nm with the options in it:
e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the
test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle".
This is unlikely to be desirable: in this case we should run
"/usr/bin/nm --blargle /usr/bin/nm".
Furthermore, as part of this nm has to detect when the passed-in $NM
contains a path, and in that case avoid doing a path search itself.
This too was thrown off if an option contained something that looked
like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run
"nm -B../prev-gcc nm" which rarely works well (and indeed it looks
to see whether that nm exists, finds it doesn't, and wrongly concludes
that nm -p or whatever does not work).
Fix all of these by clipping all options (defined as everything
including and after the first " -") before deciding whether nm
contains a path (but not using the clipped value for anything else),
and then removing all options from the path-modified nm before
looking to see whether that nm existed.
NM=my-nm now does a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM=/usr/bin/my-nm now avoids a path search and runs e.g.
/usr/bin/my-nm -B /usr/bin/my-nm
NM="my-nm -p../wombat" now does a path search and runs e.g.
/usr/bin/my-nm -p../wombat -B /usr/bin/my-nm
NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search:
../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm
This seems to be all combinations, including those used by GCC bootstrap
(which, before this commit, fails to bootstrap when configured
--with-build-config=bootstrap-lto, because the lto plugin is now using
--export-symbols-regex, which requires libtool to find a working nm,
while also using -B../prev-gcc to point at the lto plugin associated
with the GCC just built.)
Regenerate all affected configure scripts.

The AMDGPU HSA OS ABI (code object v3 and above) defines the
NT_AMDGPU_METADATA ELF note [1]. The content is a msgpack object
describing, among other things, the kernels present in the code object
and how to call them.
I think it would be useful for readelf to be able to display the content
of those notes. msgpack is a structured format, a bit like JSON, except
not text-based. It is therefore possible to dump the contents in
human-readable form without knowledge of the specific layout of the
note.
Add configury to binutils to optionally check for the msgpack C library
[2]. Add There is a new --with{,out}-msgpack configure flag, and the actual
library lookup is done using pkg-config.
If msgpack support is enabled, dumping a NT_AMDGPU_METADATA note looks
like:
$ readelf --notes amdgpu-code-object
Displaying notes found in: .note
Owner Data size Description

},
<snip>
If msgpack support is disabled, dump the contents as hex, as is done
with notes that are not handled in a special way. This allows one to
decode the contents manually (maybe using a command-line msgpack
decoder) if really needed.
