cc1: all warnings being treated as errors
The warning is bogus of course. xmalloc is guaranteed to return
non-NULL, but apparently this isn't seen in display_utf6. The same
doesn't happen with -m64, maybe due to inlining differences, I haven't
investigated fully. Easily avoided as we hardly need to use sprintf

Trying to free malloc'd memory used by the stabs and coff debug info
parsers is complicated, and traversing the trees generated requires a
lot of code. It's better to bfd_alloc the memory which allows it all
to be freed without fuss when the bfd is closed. In the process of
doing this I reverted most of commit a6336913332.
Some of the stabs handling code grows arrays of pointers with realloc,
to deal with arbitrary numbers of fields, function args, etc. The
code still does that but copies over to bfd_alloc memory when
finished. The alternative is to parse twice, once to size, then again
to populate the arrays. I think that complication is unwarranted.
Note that there is a greater than zero chance this patch breaks
something, eg. that I missed an attempt to free obj_alloc memory.
Also it seems there are no tests in the binutils testsuite aimed at
exercising objdump --debugging.

Commit f9c36cc99518 changed (and renamed) read_section_stabs with one
difference in overall behaviour. Previously read_section_stabs would
return a NULL for an empty section, which was then treated the same as
a missing section. Now an empty section is recognized and dumped.
This leads to NULL stabp and stabs_end in print_section_stabs. Since
stabs_end - STABSIZE is then a pointer to a very large address, the
test "stabp < stabs_end - STABSIZE" succeeds.
* objdump.c (print_section_stabs): Correct STABSIZE comparison.

There is some inconsistency between the behaviour of objdump -D and
objdump -s, both supposedly operating on all sections by default.
objdump -s ignores bss sections, while objdump -D dissassembles the
zeros. Fix this by making objdump -D ignore bss sections too.
Furthermore, "objdump -s -j .bss" doesn't dump .bss as it should,
since the user is specifically asking to look at all those zeros.
This change does find some tests that used objdump -D with expected
output in bss-style sections. I've updated all the msp430 tests that
just wanted to find a non-empty section to look at section headers
instead, making the tests slightly more stringent. The ppc xcoff and
spu tests are fixed by adding -j options to objdump, which makes the
tests somewhat more lenient.

If file size is calculated by bfd_get_file_size, as it is by
_bfd_alloc_and_read calls in coff_object_p, then it is cached and when
pe_ILF_build_a_bfd converts an archive entry over to BFD_IN_MEMORY,
the file size is no longer valid. Found when attempting objdump -t on
a very small (27 bytes) ILF file and hitting the pr24707 fix (commit
781152ec18f5). So, clear file size when setting BFD_IN_MEMORY on bfds
that may have been read. (It's not necessary in writable bfds,
because caching is ignored by bfd_get_size when bfd_write_p.)
I also think the PR 24707 fix is no longer neeeded. All of the
testcases in that PR and in PR24712 are caught earlier by file size
checks when reading the symbols from file. So I'm reverting that fix,
which just compared the size of an array of symbol pointers against
file size. That's only valid if on-disk symbols are larger than a
host pointer, so the test is better done in format-specific code.

Add with_source_code to the command line options that trigger

'objdump -S' download missing files via debuginfod without the need for
specifying extra command line options like '-L'.
Currently objdump -S is not able to make use files downloaded from debuginfod.
This is due to bfd_find_nearest_line_discriminator being unable to locate any
separate debuginfo files in the debuginfod cache. Additionally objdump lacked
a call to debuginfod_find_source in order to download missing source files.
Fix this by using bfd_find_nearest_line_with_alt instead of
bfd_find_nearest_line_discriminator. Also add a call to
debuginfod_find_source in order to download missing source files.

This replaces dwarf_vma, dwarf_size_type and dwarf_signed_vma with
uint64_t and int64_t everywhere. The patch also gets rid of
DWARF_VMA_FMT since we can't use that with uint64_t, and all of the
configure support for deciding the flavour of HOST_WIDEST_INT.
dwarf_vmatoa also disappears, replacing most uses with one of
PRIx64, PRId64 or PRIu64. Printing of size_t and ptrdiff_t values
now use %z and %t rather than by casting to unsigned long. Also,
most warning messages that used 0x%lx or similar now use %#lx and a
few that didn't print the 0x hex prefix now also use %#. The patch
doesn't change normal readelf output, except in odd cases where values
previously might have been truncated.

When adding libopcodes disassembler styling support for AArch64, it
feels like the results would be improved by having a new sub-mnemonic
style. This will be used in cases like:
add w16, w7, w1, uxtb #2
^^^^----- Here
And:
cinc w0, w1, ne
^^----- Here
This commit just adds the new style, and prepares objdump to handle
the style. A later commit will add AArch64 styling, and will actually
make use of the style.
As this style is currently unused, there should be no user visible
changes after this commit.

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.

(load_debug_section): Return false if dump_any_debugging isn't
set.
binutils/NEWS says of the change in --process-links semantics:
If other debug section display options are also enabled (eg
--debug-dump=info) then the contents of matching sections in both the main
file and the separate debuginfo file *will* be displayed. This is because in
most cases the debug section will only be present in one of the files.
Implying that debug info is dumped without --process-links. Indeed
that appears to be the case for readelf. This does the same for
objdump.

* objdump.c (dump_bfd): Do not exit early when !is_mainfile
&& !processlinks, instead just exclude non-debug output.
(dump_dwarf): Add is_mainfile parameter and pass to
dump_dwarf_section.
(dump_dwarf_section): Only display debug sections when
!is_mainfile and !process_links.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
Extract allowed styles from libiberty, so we don't have to worry about
our help messages getting out of date. The function probably belongs
in libiberty/cplus-dem.c but it can be here for a while to iron out
bugs.
