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.

For one, the actual error is weird:
./ld-new: target elf64-x86-64 not found
failed with: <./ld-new: target elf64-x86-64 not found>, no expected output
FAIL: ld-ifunc/ifunc-10-x86-64
although ld -V does report the elf_x86_64 emulation as supported:
$ ./ld/ld-new -V
GNU ld (GNU Binutils) 2.34.50.20200328
Supported emulations:
elf_x86_64_sol2
elf_x86_64
[...]
When using ld -m elf_x86_64_sol2 instead, one of the testcases links
successfully.
However, there's no point in pursuing this: Solaris does not support
ifunc, as can be seen in <sys/elf.h>:
/*
* GNU/Linux specific symbol type not used by Solaris
*/
#define STT_GNU_IFUNC 10
and never will, given that it has symbol capabilities as solution to
effectively the same problem:
http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/
Therefore this patch disables ifunc testing on Solaris completely by
removing Solaris from binutils/testsuite/lib/binutils-common.exp
(supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is
in the OS-specific range and conflicts with
#define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */
While the comment suggests this might be relocatable without too much
problems, the description of mbind (no formal spec AFAICS, just the
comment in the binutils patch submission) strongly suggests that this
isn't relevant to Solaris at all.
Indirectly, clearing supports_gnu_osabi on Solaris disables
supports_gnu_unique. Again, Solaris <sys/elf.h> has
/*
* GNU/Linux specific binding not used by Solaris
*/
#define STB_GNU_UNIQUE 10
so this seems the right thing to do.
Afterwards, one can remove the explicit mentions of *-*-solaris2* in
quite a number of (but not all) the ld-ifunc dump file notarget lists.
There's one fallout, though: two gas tests now XPASS because they are
xfail'ed for !supports_gnu_osabi:
XPASS: mbind sections 12
XPASS: mbind section contents 16
XPASS: mbind sections 16
XPASS: mbind section contents 16
To fix that, I've changed
#xfail: ![supports_gnu_osabi]
to notarget.

Last patch didn't manage to xfail spu due to clear_xfail *-*-*elf*.
Clearing *-*-*elf* dates back to a time when we had rather a lot more
setup_xfail patterns, so limiting it to hppa*-*-*elf*. Also,
mips-*-irix ought to have been mips-*-irix* and I'm having second
thoughts about xfailing mips and hiding what looks like a problem: If
the mips target is supposed to emit names for local section symbols
and does so for objcopy, why isn't it doing the same for ld? Also,
lots more mips targets would be subject to this test failing. So I'm
backing out those xfails and leaving it to someone more knowledgeable
about mips.
* testsuite/binutils-all/objcopy.exp (objcopy_test): Only
clear_xfail hppa*-*-*elf*. Revert mips xfails.
xfails spu due to a note section getting a different vma, and some
mips targets that give section symbols a name string. I added -p
for the executable test in an attempt to fix all the pe target fails,
but that doesn't preserve the date/time for some reason.
* testsuite/binutils-all/objcopy.exp (objcopy_test): Move xfails

With the right set of options, the second block of code dealing with

Since I was editing those lines, I've also changed the code allocating

array = malloc (n * sizeof (*array));

array = malloc (n * sizeof (int));

In commit 2b44a6a237 (" binutils: doc: make `make clean` clean more
things"), I moved the doc build artifacts to MOSTLYCLEANFILES, which
made them get removed by "make clean".
Because generating binutils.info requires makeinfo, and we do not want
to require makeinfo when building from the tarball, binutils.info should
not get removed by "make clean" (otherwise, it won't be included in the
tarball).
And to be consistent with other projects (e.g. ld and gas), we also want
to ship the built man pages in the tarball.
This patch puts back all these in MAINTAINERCLEANFILES, so that they are
bundled in the tarball, and only cleaned if you use "make
maintainer-clean".

In order to regenerate all of the configure files, I configured with
--enable-maintainer-mode, and built the 'all' target. I then did the
same thing on a source tree without this patch, and only committed
those files that changed when this patch was added.

Clang's integrated assembler supports multiple section with the same
name:
.section .text,"ax",@progbits,unique,1
nop
.section .text,"ax",@progbits,unique,2
nop
"unique,N" assigns the number, N, as the section ID, to a section. The
valid values of the section ID are between 0 and 4294967295. It can be
used to distinguish different sections with the same section name.
This is useful with -fno-unique-section-names -ffunction-sections.
-ffunction-sections by default generates .text.foo, .text.bar, etc.
Using the same string can save lots of space in .strtab.
This patch adds section_id to bfd_section and reuses the linker
internal bit in BFD section flags, SEC_LINKER_CREATED, for assmebler
internal use to mark valid section_id. It also updates objdump to
compare section pointers if 2 sections comes from the same file since
2 different sections can have the same section name.

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
more information see https://sourceware.org/elfutils/.

Changing objdump disassembly output like this always requires some
testsuite changes, with the avr and x64_64 changes simply due to
picking up better symbols, the whole point of the patch.
The mips changes are due to mips-sgi-irix changing STT_NOTYPE symbols
to STT_OBJECT, which objdump now chooses in preference to script
symbols. The problem is that objdump looks at the first symbol in the
section being disassembled, and if object type, just dumps out bytes
rather than disassembling. This results in new failures:
FAIL: JAL overflow 2
FAIL: undefined weak symbol overflow
FAIL: undefined weak symbol overflow (n32)
FAIL: undefined weak symbol overflow (n64)
So for mips-sgi-irix function symbols really do need to be function
type. I fixed a few more than just the required minimum to avoid the
above test fails.
