sim: bfin: only regen linux-fixed-code.h in maintainer mode

Since many people don't have a Blackfin toolchain available, only try to
regenerate the header file when in maintainer mode.  This file rarely changes,
and when it does, we commit the generated output, so there's almost never a
need to run directly on an end system.

Remove superfluous semicolons from testsuite throughout.

A few months ago semicolons after "return" were removed throughout the
testsuite.  However, as I pointed out in review, they're unnecessary
not just after "return", but pretty much after any tcl command.  ';'
is the command separator, and you only need it if there's another
command on the same line afterwards.

This patch was written by running:

 $ find . -name "*.exp" | xargs grep -l ";\s*$" | xargs sed -i 's/\([^#][^\s*;]*\)\s*;\s*$/\1/'

and then undoing changes to comments, and lib/future.exp.

[GDBserver] Multi-process + multi-arch

This patch makes GDBserver support multi-process + biarch.

Currently, if you're debugging more than one process at once with a
single gdbserver (in extended-remote mode), then all processes must
have the same architecture (e.g., 64-bit vs 32-bit).  Otherwise, you
see this:

... etc, etc ...

Even though the process was running a 32-bit program, GDBserver sent
back to GDB a register set in 64-bit layout.

A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a
while ago made GDB track a target_gdbarch per inferior, and as
consequence, fetch a target description per-inferior.  This patch is
the GDBserver counterpart, that makes GDBserver keep track of each
process'es XML target description and register layout.  So in the
example above, GDBserver will send the correct register set in 32-bit
layout to GDB.

A new "struct target_desc" object (tdesc for short) is added, that
holds the target description and register layout information about
each process.  Each `struct process_info' holds a pointer to a target
description.  The regcache also gains a pointer to a target
description, mainly for convenience, and parallel with GDB (and
possible future support for programs that flip processor modes).

The low target's arch_setup routines are responsible for setting the
process'es correct tdesc.  This isn't that much different to how
things were done before, except that instead of detecting the inferior
process'es architecture and calling the corresponding
init_registers_FOO routine, which would change the regcache layout
globals and recreate the threads' regcaches, the regcache.c globals
are gone, and the init_registers_$BAR routines now each initialize a
separate global struct target_desc object (one for each arch variant
GDBserver supports), and so all the init_registers_$BAR routines that
are built into GDBserver are called early at GDBserver startup time
(similarly to how GDB handles its built-in target descriptions), and
then the arch_setup routine is responsible for making
process_info->tdesc point to one of these target description globals.
The regcache module is all parameterized to get the regcache's layout
from the tdesc object instead of the old register_bytes, etc. globals.

The threads' regcaches are now created lazily.  The old scheme where
we created each of them when we added a new thread doesn't work
anymore, because we add the main thread/lwp before we see it stop for
the first time, and it is only when we see the thread stop for the
first time that we have a chance of determining the inferior's
architecture (through the_low_target.arch_setup).  Therefore when we
add the main thread we don't know which architecture/tdesc its
regcache should have.

This patch makes the gdb.multi/multi-arch.exp test now pass against
(extended-remote) GDBserver.  It currently fails, without this patch.

The IPA also uses the regcache, so it gains a new global struct
target_desc pointer, which points at the description of the process it
is loaded in.

Re. the linux-low.c & friends changes.  Since the register map
etc. may differ between processes (64-bit vs 32-bit) etc., the
linux_target_ops num_regs, regmap and regset_bitmap data fields are no
longer sufficient.  A new method is added in their place that returns
a pointer to a new struct that includes all info linux-low.c needs to
access registers of the current inferior.

The patch/discussion that originally introduced
linux-low.c:disabled_regsets mentions that the disabled_regsets set
may be different per mode (in a biarch setup), and indeed that is
cleared whenever we start a new (first) inferior, so that global is
moved as well behind the new `struct regs_info'.

On the x86 side:

I simply replaced the i387-fp.c:num_xmm_registers global with a check
for 64-bit or 32-bit process, which is equivalent to how the global
was set.  This avoided coming up with some more general mechanism that
would work for all targets that use this module (GNU/Linux, Windows,
etc.).

gdb/testsuite/gdb.cp: Fix tests for ARM C++ ABI.

The ARM C++ ABI defines constructors and destructors to return
pointers to this. The C++ tests that check the types of constructors
and destructors expect a return type of void. Conditionalize these
tests so they pass on ARM.

gdb/testsuite/ChangeLog:

In build_address_symbolic we call gdbarch_addr_bits_remove for
symbols in the symbol table but not for minimal symbols. This
causes a failure in gdb.cp/virtfunc.exp on ARM, as the address
of the virtual thunk is given an offset of 1 when in Thumb mode.

maintenance_expand_symtabs leaks a cleanup

It turns out that maintenance_expand_symtabs was missing a call to
do_cleanups.  I found this using the cleanup checker.

* symmisc.c (maintenance_expand_symtabs): Call do_cleanups.

fix up xml-support.c

xml-support.c has a function that returns a cleanup via an out parameter.

This changes this function to be a normal cleanup constructor --
returning the cleanup directly and returning the other result via an
out parameter.

This is sort of a hack, but it lets the checker work here.

I also noticed that gdb_xml_create_parser_and_cleanup does not need to
be exported any more.

* xml-support.c (gdb_xml_create_parser_and_cleanup): Rename from
gdb_xml_create_parser_and_cleanup_1.  Return a cleanup.  Remove
'old_chain' argument.  Add 'parser_result' argument.
(gdb_xml_create_parser_and_cleanup): Remove old version.
(gdb_xml_parse_quick): Update.
(xml_process_xincludes): Update.
* xml-support.h (gdb_xml_create_parser_and_cleanup): Don't
declare.

fix compile_rx_or_error

compile_rx_or_error looks like a constructor, but it can return NULL.
This patch changes it to remove the NULL return, making it work
like any other cleanup constructor.

This is a stylistic patch but I think it is also better for code to
follow the normal conventions.

* probe.c (collect_probes): Check arguments for NULL before
calling compile_rx_or_error.
* utils.c (compile_rx_or_error): Require 'rx' to be non-NULL.
Remove NULL return.

some fixes to infrun.c

This fixes some of the problems in infrun.c that the checker reported.
I filed the remaining problems as bugs.

This patch is purely stylistic.

* infrun.c (adjust_pc_after_break): Introduce an outer null
cleanup.

fix mi-cmd-var.c

This is a stylistic change in mi-cmd-var.c that adds outer cleanups
where needed by the checker.

* mi/mi-cmd-var.c (varobj_update_one): Add an outer null cleanup.

fix cli-script.c

read_command_lines_1 had some (IMNSHO) spaghetti-ish code for cleanup
handling.  This makes the code much simpler to understand, by
introducing an outer cleanup.

This is another case where a stylistic change for the checker is also
nice for the reader.

* cli/cli-script.c (read_command_lines_1): Use a null cleanup
for 'old_chain'.  Do not check 'head' before processing
cleanups.

fix mi-cmd-stack.c

mi-cmd-stack.d had a conditional cleanup, "cleanup_tuple" that
confused the checker.  However, there was no need for this, since it
was only used via do_cleanups at the end of the function, just before
another call to do_cleanups.

So, while this is a stylistic patch for the checker, I also consider
it a generic improvement for readers of the code.

* mi/mi-cmd-stack.c (list_arg_or_local): Remove
"cleanup_tuple".

fix dbxread.c

This is a stylistic change to make some code in dbxread.c analyzable
by the checker.

* dbxread.c (dbx_read_symtab): Declare 'back_to' in a more
inner scope.  Unconditionally call do_cleanups.

fix source.c

find_and_open_source can leak a cleanup.

* source.c (find_and_open_source): Call do_cleanups.

fix linux-thread-db.c

This is a stylistic change to make it so the checker can analyze a
function in linux-thread-db.c.

* linux-thread-db.c (thread_db_load_search): Unconditionally
call do_cleanups.
