Jose E. Marchesi d28b6364b1 gas: sparc: fix relaxation of CALL instruction into branches in a.out targets
This patch avoids CALL instructions to be optimized into branches if

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
initialize it [2].

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.

Thomas Preud'homme 5344555470 [GAS/ARM] Fix expansion of ldr pseudo instruction
The LDR rX, =cst pseudo-instruction suffers from two issues for loading
integer constants in Thumb mode:

- movs is used if the constant and register can be encoded using that
  instruction which leads to unexpected behavior due to its flag-setting
  behavior
- mov.w, movw and mvn are used for r13 (sp) and r15 (pc) but these
  encoding are marked as UNPREDICTABLE

This changes some code in tracepoint.c to use ui_out_emit_tuple.  One
of these involved removing an otherwise unrelated cleanup (changing

This patch adds a few more uses of ui_out_emit_tuple.  In these cases

annotate_arg_emitter, for use in stack.c, to avoid having to introduce
a new scope and reindent the code for a single call.

This patch changes various places to use ui_out_emit_tuple,

block-structured and did not involve any changes other than the
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.

H.J. Lu e133d00576 i386: Avoid dynamic symbol with GOT reference in PIE
GOT reference to global symbol in PIE will lead to dynamic symbol.  It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc.  If
a symbol isn't undefined weak symbol, don't make it dynamic in PIE and
generate R_386_RELATIVE relocation.

Yao Qi 4daf993d4d Simplify regcache_restore
This patches removes the 2nd argument of regcache_restore, because it
is only called by regcache_cpy.  In regcache_cpy, if regcache_restore
is called, dst is not readonly, but src is readonly.  So this patch
adds an assert that src is readonly in regcache_restore.
regcache_cook_read read everything from a readonly regcache cache
(src)'s register_buffer, and register status is from ->register_status.

H.J. Lu afe9edbf48 Skip PIE indirect5 and indirect6 tests on i386
On i386, since GOT reference is needed to access global symbols in PIE,
those symbols are made dynamic.  Crash happens when there is a reference
to the same global symbol with a different symbol type in a shared
object.  Since mixing different types of the same symbol doesn't work in
general, this patch skips those tests on i386 as well as compiles non-PIE
indirect5 and indirect6 tests with $NOPIE_LDFLAGS and $NOPIE_CFLAGS.

Maciej W. Rozycki 0fad29560e ELF/LD: Always consider STB_LOCAL symbols local
Do not require forced local (STB_LOCAL) symbols to have a definition in
a regular file to be considered to resolve local to the current module,
matching `elf_link_renumber_local_hash_table_dynsyms'.  In the absence
of a regular definition any reference to a STB_LOCAL symbol will have to
be garbage collected along with the undefined symbol itself, or the link
will eventually fail.  Either way the symbol concerned is not going to
be external.
