Maciej W. Rozycki c46cec3a8c ELF/BFD: Limit `_bfd_elf_link_renumber_dynsyms' call in section GC
Consistently call `_bfd_elf_link_renumber_dynsyms' only if linking a
dynamic binary, complementing code in `bfd_elf_size_dynsym_hash_dynstr'
and commit ccabcbe51e ("New attempt at fixing MIPS --gc-sections et
al."), <https://sourceware.org/ml/binutils/2005-08/msg00258.html>.

	* elflink.c (bfd_elf_size_dynamic_sections): Only call
	`_bfd_elf_link_renumber_dynsyms' after section GC if dynamic
	sections have been created.

Maciej W. Rozycki bbdd9a6894 MIPS/readelf: With `-A' also dump GOT in static binaries
A static, non-relocated global offset table will be embedded in static
binaries produced from objects containing any kind of GOT relocations,
generally PIC code.  All symbols will have been resolved in static link
in such binaries making all GOT entries local and their values final as
there is no run-time load processing further performed.

Dump such GOT with `readelf -A' like already done with regular GOT, to
make it easier to examine static code that uses accesses via the GOT
pointer.  There will be no dynamic segment or section in a static binary
to get the GOT pointer (DT_PLTGOT) from, so use section headers to find
a `.got' section instead.

Maciej W. Rozycki c4ab9505b5 MIPS/readelf: Simplify GOT[1] data availability check
Unavailable data is handled gracefully in MIPS GOT processing done by
`print_mips_got_entry', so all that is needed in special GOT[1] handling
is to verify whether data can be retrieved for the purpose of the GNU
marker check done with `byte_get'.  Remove the extra error reporting
code then, introduced with commit 75ec1fdbb7 ("Fix runtime seg-fault
in readelf when parsing a corrupt MIPS binary.") in the course of
addressing PR binutils/21344, and defer the error case to regular local

Pedro Alves b5c3668253 Don't memset non-POD types: struct btrace_insn
struct btrace_insn is not a POD [1] so we shouldn't be using memset to

Use list-initialization instead, wrapped in a "pt insn to btrace insn"
function, which looks like just begging to be added next to the
existing pt_reclassify_insn/pt_btrace_insn_flags functions.

[1] - because its field "flags" is not POD, because enum_flags has a
non-trivial default ctor.

So, VECs (given it's C roots) rely on memcpy/memcpy of VEC elements to
be well defined, in order to grow/reallocate its internal elements
array.  This means that we can only put trivially copyable types in
VECs.  E.g., if a type requires using a custom copy/move ctor to
relocate, then we can't put it in a VEC (so we use std::vector
instead).  But, as shown above, we're violating that requirement.

btrace_insn is currently not trivially copyable, because it contains
an enum_flags field, and that is itself not trivially copyable.  This
patch corrects that, by simply removing the user-provided copy
constructor and assignment operator.  The compiler-generated versions
work just fine.

Note that std::vector relies on std::is_trivially_copyable too to know
whether it can reallocate its elements with memcpy/memmove instead of
having to call copy/move ctors and dtors, so if we have types in
std::vectors that weren't trivially copyable because of enum_flags,
this will make such vectors more efficient.

Alan Modra bce964aa6c PR 21412, get_reloc_section assumes .rel/.rela name for SHT_REL/RELA.
This patch fixes an assumption made by code that runs for objcopy and
strip, that SHT_REL/SHR_RELA sections are always named starting with a
.rel/.rela prefix.  I'm also modifying the interface for
elf_backend_get_reloc_section, so any backend function just needs to
handle name mapping.

This changes some spots to use ui_out_emit_list.  This only touches
"easy" cases, where the cleanup was used in a block-structured way.
There's also one more use of ui_out_emit_tuple in here.

This patch adds a few more uses of ui_out_emit_tuple.  In these cases
a slightly more complicated change was needed.  This also adds

This patch changes various places to use ui_out_emit_tuple,

obvious replacement.

Simon Marchi ebe553db6c doc: Improve documentation about MI thread output
I noticed that the documentation on how the info about threads is output
in MI is duplicated and not up to date.  The duplication is between the
"GDB/MI Thread Information" page and the -thread-info result
description.

I improved the "GDB/MI Thread Information" page a bit and referred to it
in the -thread-info doc.  This way, the -thread-info doc is more precise
(it did not mention the "threads" and "current-thread-id" attributes)
and concise.

gdb/doc/ChangeLog:

	* gdb.texinfo (GDB/MI Thread Information): Add missing
	fields, re-word some things.
	(GDB/MI Thread Commands): Describe fields found in the output of
	-thread-info, remove description of fields in the
	thread output tuple, replace with a cross-reference to "GDB/MI
	Thread Information".

Simon Marchi 9be21bb4d4 Remove dead code and "current" field from MI thread output doc
The MI documentation says that -thread-info output contains a "current"
field in the current thread tuple, with the value "*".  Current GDB
master does not do this, and I couldn't find any GDB version that did.
I suspect that it was never the case.

The code that would correspond to this in print_thread_info_1 is
essentially dead code.  The calls to uiout->text end up in
mi_out::do_text, which is empty.

This patch removes the documentation bit and the dead code.  This
"current" field is not necessary, since -thread-info outputs a
"current-thread-id" field.

gdb/ChangeLog:

	* thread.c (print_thread_info_1): Remove dead code.

gdb/doc/ChangeLog:

	* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
	from -thread-info output.
