Yao Qi f6bb7db35d New gdb.reverse test case for aarch64 instructions
This patch adds a test case to test the process record for some of
aarch64 instructions.

In each function, GDB turns on process record, and single step until
program goes to the end of the function.  Then, single step backward.
In each of forward single step and backward single step, the contents
of registers are saved, and test compares them.  If there is any
differences, a FAIL is emitted.

The test is flexible, and we can test other instructions easily in the
future.

Martin Galvan c9cf6e20c6 Rename in_function_epilogue_p to stack_frame_destroyed_p
We concluded that gdbarch_in_function_epilogue_p is misnamed, since it
returns true if the given PC is one instruction after the one that
destroyed the stack (which isn't necessarily inside an epilogue),
therefore it should be renamed to stack_frame_destroyed_p.

I also took the liberty of renaming the arch-specific implementations to
*_stack_frame_destroyed_p as well for consistency.

Andrew Burgess 7bd0be3a9b gdb: Remove register class specific layout names.
The layout command supports the layout names $FREGS, $GREGS, $SREGS,
and $REGS. The intention of these layout names was to display the tui
register window with a specific set of registers.

First, these layout names no longer work, and haven't for a while, using
any of them will just result in switching to the general register view.

Second there is already the command 'tui reg GROUP' command to set the
displayed register set to GROUP, so making the layout command also
control the register set feels like unnecessary overloading of the
layout command.

This commit removes all code relating to supporting the register set
specific names from the layout command.  Afterwards the user can select
an available layout using the layout command, and control the choice of
register set using the 'tui reg GROUP' command.

Joel Brobecker 0b6e5e1085 Memory leak reading frame register during inferior event handling
When using a conditional breakpoint where the condition evaluated
to false a large number of times before the program stopped,
a user reported that GDB's memory consumption was growing very
quickly until it ran out of memory.

The problem was tracked down to temporary struct values being created
each time the program stops and handles an inferior event.  Because
the breakpoint condition usually evaluates to false, there can be
a fairly large number of such events to be handled before we eventually
return the prompt to the user (which is when we would normally purge
such values).

This patch fixes the issue by making sure that handle_inferior_event
releases all new values created during its execution.

It is obvious why that happens, dummy_frame_pop() will call compile objfile
cleanup which will free that objfile and NAME then becomes a stale pointer.

> don't we register a cleanup to release in OBJFILE in compile_object_run?

Chung-Lin Tang 68880f311c ELF options may be missing from `ld --help' output
nios2-linux has an emulation named "nios2linux", and happens to not include
another extra emulation with a name matching *elf*.  This makes nios2-linux
left out of the ELF options printing targets, which is unintended.

	* configure.ac (AC_PROG_GREP): Check for grep program.
	(elf_list_options,elf_shlib_list_options,elf_plt_unwind_list_options):
	Enable ELF option printing for emulations containing
	'TEMPLATE_NAME=elf32'.

H.J. Lu 25070364b0 Don't generate PLT relocations for now binding

entres with 8-byte .plt.got entries.

Jan Kratochvil 36de76f9cc compile: New 'compile print'
It is planned the existing GDB command 'print' will be able to evaluate its
expressions using the compiler.  There will be some option to choose between
the existing GDB evaluation and the compiler evaluation.  But as an
intermediate step this patch provides the expression printing feature as a new
command.

I can imagine it could be also called 'maintenance compile print' as in the
future one should be able to use its functionality by the normal 'print'
command.

There was a discussion with Eli about the command name:
	https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html
As there were no other comments yet I haven't renamed it yet, before there is
some confirmation about settlement on the final name.

Support for the GDB '@' operator to create arrays has been submitted for GCC:
	[gcc patch] libcc1: '@' GDB array operator
	https://gcc.gnu.org/ml/gcc-patches/2015-03/msg01451.html
