f493c2174e Get rid of fprintf_vma and sprintf_vma
These two macros print either a 16 digit hex number or an 8 digit
hex number.  Unfortunately they depend on both target and host, which
means that the output for 32-bit targets may be either 8 or 16 hex
digits.

Replace them in most cases with code that prints a bfd_vma using
PRIx64.  In some cases, deliberately lose the leading zeros.
This change some output, notably in base/offset fields of m68k
disassembly which I think looks better that way, and in error
messages.  I've kept leading zeros in symbol dumps (objdump -t)
and in PE header dumps.

4f46c0bc36 opcodes: add new sub-mnemonic disassembler style
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.

695c6dfe7e PR29370, infinite loop in display_debug_abbrev
The PR29370 testcase is a fuzzed object file with multiple
.trace_abbrev sections.  Multiple .trace_abbrev or .debug_abbrev
sections are not a violation of the DWARF standard.  The DWARF5
standard even gives an example of multiple .debug_abbrev sections
contained in groups.  Caching and lookup of processed abbrevs thus
needs to be done by section and offset rather than base and offset.
(Why base anyway?)  Or, since section contents are kept, by a pointer
into the contents.

f07c08e115 binutils/dwarf.c: abbrev caching
I'm inclined to think that abbrev caching is counter-productive.  The
time taken to search the list of abbrevs converted to internal form is
non-zero, and it's easy to decode the raw abbrevs.  It's especially
silly to cache empty lists of decoded abbrevs (happens with zero
padding in .debug_abbrev), or abbrevs as they are displayed when there
is no further use of those abbrevs.  This patch stops caching in those
cases.

	* dwarf.c (record_abbrev_list_for_cu): Add free_list param.
	Put abbrevs on abbrev_lists here.
	(new_abbrev_list): Delete function.
	(process_abbrev_set): Return newly allocated list.  Move

	(find_and_process_abbrev_set): ..here, new function.  Handle
	lookup of cached abbrevs here, and calculate start and end
	for process_abbrev_set.  Return free_list if newly alloc'd.
	(process_debug_info): Consolidate cached list lookup, new list
	alloc and processing into find_and_process_abbrev_set call.
	Free list when not cached.
	(display_debug_abbrev): Similarly.

d0ff5ca959 [AArch64] Support AArch64 MTE memory tag dumps in core files
The Linux kernel can dump memory tag segments to a core file, one segment
per mapped range. The format and documentation can be found in the Linux
kernel tree [1].

The following patch adjusts bfd and binutils so they can handle this new
segment type and display it accordingly. It also adds code required so GDB
can properly read/dump core file data containing memory tags.

Upon reading, each segment that contains memory tags gets mapped to a
section named "memtag". These sections will be used by GDB to lookup the tag
data. There can be multiple such sections with the same name, and they are not
numbered to simplify GDB's handling and lookup.

There is another patch for GDB that enables both reading
and dumping of memory tag segments.

Tested on aarch64-linux Ubuntu 20.04.

b95830931f Regenerate with automake-1.15.1
Until we update the recommended versions of autoconf/automake, files
should be regenerated with automake-1.15.1 and autoconf-2.69.  That's
not because we think those versions are golden, and newer versions are
bad.  It's simply because maintainers want to be able to update
configury files without trouble, and if someone regenerates files with
automake-1.16.5 then --enable-maintainer-mode builds will hit errors:

checking that generated files are newer than configure... configure.ac:26: error: version mismatch.  This is Automake 1.15.1,
configure.ac:26: but the definition used by this AM_INIT_AUTOMAKE
configure.ac:26: comes from Automake 1.16.5.  You should recreate
configure.ac:26: aclocal.m4 with aclocal and run automake again.
WARNING: 'automake-1.15' is probably too old.

Correcting this requires regenerating the files by hand.

0772daccb3 objcopy: bfd_alloc orelocation
This fixes an inconsequential objcopy memory leak.  I'd normally
ignore reports of leaks like this one, that are merely one block or

99f647e200 Trailing spaces in objdump -r header
git commit 202be274a4 went a little wild in removing trailing spaces
in gas/testsuite/gas/i386/{secidx.d,secrel.d}, causing
x86_64-w64-mingw32  +FAIL: i386 secrel reloc
x86_64-w64-mingw32  +FAIL: i386 secidx reloc

I could have just replaced the trailing space, but let's fix the
objdump output instead.  Touches lots of testsuite files.

0e3c1eebb2 Remove use of bfd_uint64_t and similar
Requiring C99 means that uses of bfd_uint64_t can be replaced with
uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and
BFD_HOST_64_BIT.  This patch does that, removes #ifdef BFD_HOST_*
and tidies a few places that print 64-bit values.

be38442dda PR29171, invalid read causing SIGSEGV
The fix here is to pass "section" down to read_and_display_attr_value.
The test in read_and_display_attr_value is a little bit of hardening.

	to read_and_display_attr_value2.
