For ELF targets, section symbols are required only for relocations.
With -ffunction-sections -fdata-sections, there can be many unused
section symbols. Sizes of libstdc++.a on Linux/x86-64 in GCC 11 are
With unused section symbols : 39411698 bytes
Without unused section symbols: 39227002 bytes
The unused section symbols in libstdc++.a occupy more than 180 KB.
Add BSF_SECTION_SYM_USED to indicate if a section symbol should be
included in the symbol table. The BSF_SECTION_SYM_USED should be set
if the section symbol is used for relocation or the section symbol is
always included in the symbol table.
Add keep_unused_section_symbols to bfd_target to indicate if unused
section symbols should be kept. If TARGET_KEEP_UNUSED_SECTION_SYMBOLS
is defined as FALSE, unused ection symbols will be removed.
Tested on Linux/x86. Other ELF backends need to:
1. Define TARGET_KEEP_UNUSED_SECTION_SYMBOLS to FALSE.
2. Mark used section symbols in assembler backend.
3. Remove unused section symbols from expected assembler and linker
outputs.

RISC-V instruction/code is always little endian, but data might be
big-endian. Therefore, we can not use the original bfd_get/bfd_put
to get/put the code for big endian targets. Add new riscv_get_insn
and riscv_put_insn to always get/put code as little endian can resolve
the problem. Just remember to update them once we have supported
the 48-bit/128-bit instructions in the future patches.

This commit adds dumping of enumerands in this general form:
0x3: (kind 8) enum eleven_els (size 0x4) (aligned at 0x4)
ELEVEN_ONE: 10
ELEVEN_TWO: 11
ELEVEN_THREE: -256
ELEVEN_FOUR: -255
ELEVEN_FIVE: -254
...
ELEVEN_SEVEN: -252
ELEVEN_EIGHT: -251
ELEVEN_NINE: -250
ELEVEN_TEN: -249
ELEVEN_ELEVEN: -248
The first and last enumerands in the enumerated type are printed so that
you can tell if they've been cut off at one end or the other. (For now,
there is no way to control how many enumerands are printed.)
The dump output in general is improved, from this sort of thing a few
days ago:

In particular, indented subsections are only present for actual structs
and unions, not forwards to them, and the structure itself doesn't add a
spurious level of indentation; structure field names are easier to spot
(at the cost of not making them look so much like C field declarations
any more, but they weren't always shown in valid decl syntax even before
this change) the size, type kind, and alignment are shown for all types
for which they are meaningful; bitfield info is only shown for actual
bitfields within structures and not ordinary integral fields; and type
IDs are never omitted. Type printing is in general much more consistent
and there is much less duplicated code in the type dumper.
There is one user-visible effect outside the dumper: ctf_type_(a)name
was erroneously emitting a trailing space on the name of slice types,
even though a slice of an int and an int with the corresponding encoding
represent the same type and should have the same print form. This
trailing space is now gone.

C allows you to do only a very few things with entities of incomplete
type (as opposed to pointers to them): make pointers to them and give
them cv-quals, roughly. In particular you can't sizeof them and you
can't get their alignment.
We cannot impose all the requirements the standard imposes on CTF users,
because the deduplicator can transform any structure type into a forward
for the purposes of breaking cycles: so CTF type graphs can easily
contain things like arrays of forward type (if you want to figure out
their size or alignment, you need to chase down the types this forward
might be a forward to in child TU dicts: we will soon add API functions
to make doing this much easier).
Nonetheless, it is still meaningless to ask for the size or alignment of
forwards: but libctf didn't prohibit this and returned nonsense from
internal implementation details when you asked (it returned the kind of
the pointed-to type as both the size and alignment, because forwards
reuse ctt_type as a type kind, and ctt_type and ctt_size overlap). So
introduce a new error, ECTF_INCOMPLETE, which is returned when you try
to get the size or alignment of forwards: we also return it when you try
to do things that require libctf itself to get the size or alignment of
a forward, notably using a forward as an array index type (which C
should never do in any case) or adding forwards to structures without
specifying their offset explicitly.
The dumper will not emit size or alignment info for forwards any more.
(This should not be an API break since ctf_type_size and ctf_type_align
could both return errors before now: any code that isn't expecting error
returns is already potentially broken.)

Dump more details about the types found in data object and function info
sections (the type ID and recursive info on the type itself, but not on
its members). Before now, this was being dumped for entries in the
variable section, but not for the closely-related function info and data
object sections, which is inconsistent and makes finding the
corresponding types in the type section unnecessarily hard. (This also
gets rid of code in which bugs have already been found in favour of the
same code everything else in the dumper uses to dump types.)
While we're doing that, change the recursive type dumper in question to
recursively dump info on arrays' element type, just as we do for all
types that reference other types. (Arrays are not a kind of reference
type in libctf, but perhaps we should change that in future and make
ctf_type_reference return the element type.)

In most places in CTF dumper output, we emit 0x... for hex strings, but
in three places (top-level type IDs, string table offsets, and the file
magic number) we don't emit the 0x.
This is very confusing if by chance there are no hex digits in the
output. Add 0x consistently to everything, and adjust tests
accordingly. While we're at it, improve the indentation of the output
so that subsequent lines in aggregate output are indented by at least as
many columns as the colon in the type output. (Subsequent indentation
is still 4 spaces at a time.)

Match the condition used in `elf_vax_instantiate_got_entries' for the
creation of GOT entries in the processing of R_VAX_GOT32 relocations in
`elf_vax_check_relocs', removing incorrect warnings about a GOT addend
mismatch like:
./ld-new: tmpdir/got-local-ref-off-r.o: warning: GOT addend of 1 to `bar_hidden' does not match previous GOT addend of 0
./ld-new: tmpdir/got-local-ref-off-r.o: warning: GOT addend of 2 to `bar_hidden' does not match previous GOT addend of 0
and corresponding failures with the test cases newly added here:
FAIL: GOT test (executable hidden reference with offset)
FAIL: GOT test (executable visible reference with offset)
for symbols that are considered local for reasons other than having been
forced local with a version script, which is usually the ELF visibility.
Correct code is produced regardless, but the warning breaks `-Werror'
compilation and may upset people regardless.
Interestingly this shows with executable links only, because in shared
library links code from `elf_link_add_object_symbols' triggers:
/* If the symbol already has a dynamic index, but
visibility says it should not be visible, turn it into
a local symbol. */
switch (ELF_ST_VISIBILITY (h->other))
{
case STV_INTERNAL:
case STV_HIDDEN:
(*bed->elf_backend_hide_symbol) (info, h, TRUE);
dynsym = FALSE;
break;
}
that sets `h->forced_local' like with a version script.
Add suitable test cases including disassembly to verify correct code has
been produced where no warnings have been issued, and that warnings do
get issued where necessary. Do not verify (broken) code produced in the
latter case; we should probably make the warning an error, or preferably
actually start supporting GOT references with different addends as they
appear feasible with explicitly relocated GOT that we use.

Prior to this patch
ld -shared --version-script=pr26979.ver pr26978a.o pr26978b.o
results in
ld: pr26978b.o: in function `foo_v1':
(.text+0x0): multiple definition of `foo@v1'
ld: pr26978b.o:(*IND*+0x0): multiple definition of `foo'

ld -shared --version-script=pr26979.ver pr26978b.o pr26978a.o
results in no error, but some odd dynamic symbols.
... 0 NOTYPE GLOBAL DEFAULT 7 foo@v1
... 0 NOTYPE WEAK DEFAULT 7 foo@@v1
When linking an undecorated reference to foo against such a shared
library, ld complains about multiple definitions of foo@v1 while gold
creates a dynamic reference to foo@v1. That results in foo@v1 being
used at runtime.
While we could error in both cases, it is reasonable to say foo@v1 and
foo@@v1 are in fact the same symbol. (Same name, same version. The
only real difference is that foo@@v1 satisfies a reference to plain
foo, while foo@v1 does not.) Just as merging a weak undecorated sym
with a strong sym results in the strong sym prevailing, so should the
strong foo@v1 prevail. And since there is a definition that satisfies
plain foo, the foo@@v1 variety of dynamic symbol should be emitted at
the foo@v1 value. That makes the testcase that currently links
continue to produce a shared library, and that shared library can now
be used by both ld and gold with the same runtime behaviour as when
using gold with the odd dynamic symbol library.

Add extended mnemonics used in the HLASM assembler. All of them are
just aliases for instructions we already support and help when
assembling code which was written for the HLASM assembler.
The HLASM mnemonics are documented here:
https://www.ibm.com/support/knowledgecenter/SSENW6_1.6.0/com.ibm.hlasm.v1r6.asm/asmr1023.pdf
See the 'Branching with extended mnemonic codes' chapter.
objdump will still print the existing mnemonics with the exception of
relative nop branches (i.e. conditional branches with an empty
condition code mask). Now we have jnop and jgnop which will be used
by objdump when possible.
The same change have been applied to the LLVM assembler:
