abfd->section_count unexpectedly changes between 218 and 248 in:

_bfd_generic_link_add_symbols increases section_count

and simple_restore_output_info later reads unallocated part of saved_offsets.

Add g10 support to rl78-tdep.c.

The g10 is an rl78 variant which has fewer registers.  Aside from the
obvious addition of a new register_name() function which omits
registers which the g10 lacks, this change also updates the
return_value() function with the conventions specified by the ABI for
finding and setting return values.

sim: ppc: drop $(LIBS) from psim dependency

When cross-compiling GDB for PPC, there's a prerequisite "-lz" for psim
that results in a build failure. With such prerequisite, GNU Make will
try to search the library from build machine's /usr/lib which is wrong.
On 64-bit Linux build machines the compilation will fail because of this.

sim: delete duplicate SIGINT handling

Many of the simulators change the SIGINT handler.
E.g., moxie/interp.c:

  sigsave = signal (SIGINT, interrupt);

However, this is unnecessary.
remote-sim.h already provides an API for asynchronously stopping
a sim; and both gdb and the drivers (run.c and nrun.c at least,
I didn't check the others) install a SIGINT handler which
calls this method.

	Revise signal mapping function in GDB interface for RX sim.

	sim/rx/gdb-if.c had a function named `rx_signal_to_host'.  This
	function mapped signal numbers used by the BSP to host signal
	numbers which, at one time a while back, were used by GDB
	as target signal numbers.  This change updates the signal
	numbers returned to be those names prefixed with "GDB_SIGNAL_"
	as defined in include/gdb/signals.h.

	It also changes the name of the function somewhat to better
	match what the function currently does.  I noticed that this
	function is not static - and there's no reason for it not
	to be - so I made it static too.

	* gdb-if.c (rx_signal_to_host):  Rename to
	`rx_signal_to_gdb_signal'.  Make static.  Update all callers
	to use new name.  Use signal names from include/gdb/signals.h.

The PT_DYNAMIC segment was being hard coded to have read, write, and

Deleting this code allows the default linker behavior which is to set the
dynamic segment to the same permissions as the sections that make it up.

This change alters one existing test case to check the segment flags for
PT_DYNAMIC.

Fix PR16220

This patch removes startup_gdbarch because it is not used anymore.
After this patch,

 [PATCH] Multi-process + multi-arch: GDB
 https://sourceware.org/ml/gdb-patches/2012-11/msg00228.html

global variable target_gdbarch is removed and gdbarch becomes
per-inferior.  Then, we don't have to keep global variable
startup_gdbarch.

Rebuild GDB with all targets.  Is it OK?

Control powerpc64-ld provision of register save/restore

This patch allows the user to override powerpc64-ld's default for
providing linker generated register save and restore functions as used
by gcc -Os code.  Normally these are not provided by ld -r, so Linux
kernel modules have needed to include their own copies.

	* elf64-ppc.c (ppc64_elf_func_desc_adjust): Use it to control
	provision of out-of-line register save/restore routines.
ld/
	* emultempl/ppc64elf.em (params): Init new field.
	(ppc_create_output_section_statements): Set params.save_restore_funcs
	default.
	(PARSE_AND_LIST_*): Add support for --save-restore-funcs and
	--no-save-restore-funcs.
add "this" pointers to more target APIs

A subsequent pass introduces delegation helper functions to the target
API.  This delegation is much cleaner if the target_ops pointer is
directly available at delegation time.

This patch adds the "this" pointer to various to_* methods for this
purpose.

This updates a number of ports which I am unable to test.  Please give
them a look-over.  Any possible problem here is trivial, though, as
all that is required is adding an argument to a function.

introduce and use find_target_at

This patch adds find_target_at to determine whether a target appears

find_record_target a bit, and is generally useful.

add make-target-delegates

This patch adds a new script, call make-target-delegates, which
auto-generates some target delegation code based on annotations in
target.h.  This adds the new delegation macros, the new generated
file, and adds the necessary calls to the new generated functions to
target.c.  It doesn't, however, add any actual annotations to the
target methods, leaving these for separate patches.

add target method delegation

This patch replaces some code in the record targets with target method
delegation.

record-full.c stores pointers to many target methods when the record
target is pushed.  Then it later delegates some calls via these.  This
is wrong because it violates the target stack contract.  In particular
it is ok to unpush a target at any stratum, but record-full does not
keep track of this, so it could potentially call into an unpushed
target.

This patch fixes the problem by using the newly-introduced generic
approach to target delegation for the methods in question.
