When a coredump is generated, there are a few registers in
ARC HS that are put under a special section, namely ".reg-v2".
It is for backward compatibility reasons with older tools that
we have decided not to extend the generic ".reg" section.
This patch makes it possible to display the information better
regarding that section. Compare the output of "readelf" without
and with these changes:
$ readelf -n core # without the patch
...
LINUX 0x0000000c Unknown note type: (0x00000600)
description data: 78 08 00 00 2f 6c 64 2d 75 43 6c 69

In another commit (soon to be submitted), GDB will makes use of these
changes to parse the extra section and its registers.

The idea here is to get rid of a lot of file related static vars used

(main): Don't set cmdline.file_name.
This is another one where not cleaning up sufficiently after
processing one file can lead to errors when processing the next file.
We have ngnuchains non-zero but gnuchains NULL in the following:
off < ngnuchains && (gnuchains[off] & 1) == 0
* readelf.c (process_symbol_table): Clear ngnuchains, ngnubuckets
and nbuckets.
This patch is aimed at fixing a number of oss-fuzz segfaults that
don't reproduce reliably with their current infrastructure, the
problem being that one invocation of readelf is effectively being run
on multiple object files. I believe that these segfaults could be
reliably reproduced with just two fuzzed objects being presented to
readelf, but those inputs are currently not identified by oss-fuzz.
So there is some guesswork involved in this patch. The idea here is
to clear stashed data such as symtab_shndx_list that is processed
using section header info, at the same time that header info is
cleared.
* readelf.c (process_section_headers): Free dynamic symbols etc.
earlier.
This fixes two leaks found in the new code supporting display of
dynamic symbols retrieved via dynamic tags.
* readelf.c (get_num_dynamic_syms): Formatting. Don't return
on error without freeing.
(process_dynamic_section): Don't recreate dynamic symbols from
dynamic tag info when the dynamic symbols have already been
read via section headers.
When readelf is processing more than one file, static bss vars won't
start out as zero for the second file unless they are cleared.
* readelf.c (process_symbol_table): Zero gnubuckets, gnuchains
etc. after freeing.
When reconstructing dynamic symbol table from the PT_DYNAMIC segment,
compute dynamic symbol table size from hash table. For DT_HASH, the
number of dynamic symbol table entries equals the number of chains.
For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL
indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all
symbols with STB_LOCAL binding before symbols with other bindings and
all undefined symbols defined ones in dynamic symbol table, the highest
symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol
table index.
Rewrite print_dynamic_symbol to dump dynamic symbol table for --dyn-syms
and --syms --use-dynamic.

This patch fixes a leak of qualified_name caused by 4c83662712 and a
double free introduced by fd486f32d1. Not breaking out of the loop
results in an error: "failed to seek to next archive header". That's
slightly better than silently preventing the possibility of endless
loops.
* readelf.c (process_archive): Don't double free qualified_name.
Don't break out of loop with "negative" archive_file_size, just
set file offset to max.
With a crafted "negative" ar_hdr.ar_size it is possible to make
readelf loop. This patch catches the overflow in a file offset
calculation.
* readelf.c (process_archive): Prevent endless loop.
process_symbol_table () has
unsigned long num_syms;
...
for (si = 0, psym = symtab; si < num_syms; si++, psym++)
We should use unsigned long to iterate over num_syms.
* readelf.c (process_symbol_table): Use unsigned long for si.
This extracts code reading symbol tables into a common function that
tidies up after errors. I've also changed an error reporting multiple
string tables to an error on multiple symbol tables.
* readelf.c (get_symbols): New function.
(process_relocs, ia64_process_unwind, hppa_process_unwind),

In git commit fd486f32d1 I put some static variables used by
get_symbol_for_build_attribute in a file scope ba_cache struct. This
was to prevent leaks in get_symbol_for_build_attribute, and to tidy up
before readelf exited. The patch wasn't quite right though. When
readelf processes more than one file it was possible to double free
arrays allocated in get_symbol_for_build_attribute.

debuginfod is a lightweight web service that indexes ELF/DWARF
debugging resources by build-id and serves them over HTTP. This patch
enables objdump and readelf to query debuginfod servers when they are
otherwise not able to find separate debug files. Binutils can be built
with debuginfod using the --with-debuginfod configure option. This
requires that libdebuginfod be installed and found at configure time.
debuginfod is packaged with elfutils, starting with version 0.178. For
