This patch enhances the MSP430 port of GAS so that, if requested, it will
generate warning messages about an instruction that changes the interrupt
state not being followed by a NOP instruction.

	* config/msp430/msp430.c: Replace known mcu array with known
	msp430 ISA mcu name array.
	Accept any name for -mmcu option.
	Add -mz option to warn about missing NOP following an interrupt
	status change.
	(check_for_nop): New.
	(msp430_operands): Emit a warning, if requested, when an interrupt
	changing instruction is not followed by a NOP.
	* doc/c-msp430.c: Document -mz option.

	* gas/msp430/bad.d: Add -mz option.
	* gas/msp430/bad.s: Add more cases where warnings should be
	generated.
	* gas/msp430/bad.l: Add expected warning messages.
comment fixes

This fixes up a few mildly erroneous comments in probe.h.

	* probe.h (parse_probes, find_probe_by_pc)
	(find_probes_in_objfile): Fix comments.
change probes to be program-space-independent

This changes the probes to be independent of the program space.

After this, when a probe's address is needed, it is determined by
applying offsets at the point of use.

This introduces a bound_probe object, similar to bound minimal
symbols.  Objects of this type are used when it's necessary to pass a
probe and its corresponding objfile.

This removes the backlink from probe to objfile, which was primarily
used to fetch the architecture to use.

This adds a get_probe_address function which calls a probe method to
compute the probe's relocated address.  Similarly, it adds an objfile
parameter to the semaphore methods so they can do the relocation
properly as well.

move probes to be per-bfd

This patch moves the probe data from the objfile to the per-BFD
object.  This lets the probes be shared between different inferiors
(and different objfiles when dlmopen is in use, should gdb ever handle
that).

2014-03-03  Tom Tromey  <tromey@redhat.com>

	(elf_get_probes, probe_key_free, _initialize_elfread): Probes are
	now per-BFD, not per-objfile.
