This patch is part of a series of patches to introduce a few changes to the
Armv8.5-A Memory Tagging Extension. This patch updates the st*g instructions
to use a previously reserved field for a new register operand. Thus the
new versions of the instructions are as follows:
- STG Xt, [<Xn|SP>, #<simm>]
- STG Xt, [<Xn|SP>, #<simm>]!
- STG Xt, [<Xn|SP>], #<simm>
- STZG Xt, [<Xn|SP>, #<simm>]
- STZG Xt, [<Xn|SP>, #<simm>]!
- STZG Xt, [<Xn|SP>], #<simm>
- ST2G Xt, [<Xn|SP>, #<simm>]
- ST2G Xt, [<Xn|SP>, #<simm>]!
- ST2G Xt, [<Xn|SP>], #<simm>
- STZ2G Xt, [<Xn|SP>, #<simm>]

- STZ2G Xt, [<Xn|SP>], #<simm>

This replaces the pointer and length parameters of target_pass_signals

the fallout.
In infrun.c, the signal_stop, signal_print, signal_program,
signal_catch, signal_pass globals are currently pointers to
heap-allocated memory. I see no point in that, so I converted them to
arrays. This allows simplifying the calls to
target_pass_signals/target_program_signals, since we can pass the
array directly, which can implicitly convert to gdb::array_view.

Static members in C++ structs are global data and therefore not part of the

part of the struct type at that point.

This reimplements the manually-written scoped_finish_thread_state
class as a forward_scope_exit instantiation. forward_scope_exit has
the same interface as scoped_finish_thread_state, so nothing else has
to change.
A forward_scope_exit is preferred over make_scope_exit here because
infrun.c:normal_stop needs to wrap scoped_finish_thread_state in a
gdb::optional. Since we need the type there, might as well use it
everywhere.

Andrew Burgess <andrew.burgess@embecosm.com>
* gdbthread.h: Include "common/forward-scope-exit.h".
(scoped_finish_thread_state): Redefine custom class in terms of
forward_scope_exit.
This adds a template that can be used to automatically instantiate
scope_exit-like types that wrap some cleanup function. The
instantiated type has a ctor that has the same interface as the
wrapped function. While the "magic" is just straight C++11, the
intended use is via the FORWARD_SCOPE_EXIT macro, which is a minimal
macro that avoids spelling out the wrapped function name more than
once:
void some_function (int foo, object *bar);
using some_function_fce = FORWARD_SCOPE_EXIT (some_function);
some_function_fce cleanup (some_int, some_obj_ptr);
The above runs:
some_function (some_int, some_obj_ptr);
at scope exit.
This is mainly useful as opposed to a simpler SCOPE_EXIT when you need
to:
- cancel the scope_exit, in which case you need the object's name
- wrap the scope_exit in a gdb::optional, in which case you need the
scope_exit's type in advance.
More details in the code comments.
gdb/ChangeLog:
2019-01-23 Pedro Alves <palves@redhat.com>
Andrew Burgess <andrew.burgess@embecosm.com>
* common/forward-scope-exit.h: New file.
This add a new template class scope_exit. scope_exit is a
general-purpose scope guard that calls its exit function at the end of
the current scope. A scope_exit may be canceled by calling the
"release" method. The API is modeled on P0052R5 - Generic Scope Guard
and RAII Wrapper for the Standard Library, which is itself based on
Andrej Alexandrescu's ScopeGuard/SCOPE_EXIT.
The main advantage of scope_exit is avoiding writing single-use RAII
classes and its boilerplate. Following patches will remove a few of
such classes.
There are two forms available:
- The "make_scope_exit" form allows canceling the scope guard. Use
it like this:
auto cleanup = make_scope_exit ( <function, function object, lambda> );
...
cleanup.release (); // cancel
- If you don't need to cancel the guard, you can use the SCOPE_EXIT
macro, like this:
SCOPE_EXIT { /* any code you like here. */ }
Note: scope_exit instances do not allocate anything on the heap.

* compile/gcc-c-plugin.h: Include compile-internal.h.
This removes the EXTERN define from stabsread.h. This is the only
spot that still uses this approach, and it interfered with sorting the
includes in stabsread.c.
Tested by rebuilding.

* stabsread.c (EXTERN): Do not define.
(symnum, next_symbol_text_func, processing_gcc_compilation)
(within_function, global_sym_chain, global_stabs)
(previous_stab_code, this_object_header_files)
(n_this_object_header_files)
(n_allocated_this_object_header_files): Define.
* stabsread.h (EXTERN): Never define. Use "extern".
E.g. in gdb.base/default.exp, valgrind detects leaks such as
==17663== 1,438 bytes in 101 blocks are definitely lost in loss record 2,804 of 2,884
==17663== at 0x4C2BE6D: malloc (vg_replace_malloc.c:309)
==17663== by 0x418A17: xmalloc (common-utils.c:44)

...
Fix the leak by using an unique_xmalloc_ptr for history_value.
