729662a522 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.

47591c29ad Eliminate enum bpstat_signal_value, simplify random signal checks further.
After the previous patch, there's actually no breakpoint type that
returns BPSTAT_SIGNAL_HIDE, so we can go back to having
bpstat_explains_signal return a boolean.  The signal hiding actually
disappears.

427cd150ee Fix PR cli/15603
This fixes PR cli/15603.

The bug here is that when a software watchpoint is being used, gdb
will stop responding to C-c.  This is a regression caused by the
"catch signal" patch.

The problem is that software watchpoints always end up on the bpstat
list.  However, this makes bpstat_explains_signal return
BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a
"random signal".

The fix is to change bpstat_explains_signal to handle this better.  I
chose to do it in a "clean API" way, by passing the signal value to
bpstat_explains_signal and then adding an explains_signal method for
watchpoints, which handles the specifics.

Built and regtested on x86-64 Fedora 18.
New test case included.

	* break-catch-sig.c (signal_catchpoint_explains_signal): Add 'sig'
	argument.
	* breakpoint.c (bpstat_explains_signal): Add 'sig' argument.
	Special case signals other than GDB_SIGNAL_TRAP.

f6de8ec262 create_breapoint / explicit mode: Error out if there's garbage after the breakpoint location.
If !PARSE_CONDITION_AND_THREAD, then ARG is just the location, nothing
else.  The fact that the describing comment of create_breakpoint
doesn't mention this just looks like an oversight of when extra_string
was added.  "parse_condition_and_thread" has been a misnomer ever
since extra_string was added -- better rename it avoid more confusion.
This makes it "parse_arg", as that'll remain stable even if/when more
explicit parameters are added.

d80ee84fe2 Change detach_breakpoints to take a ptid instead of a pid
Before this change, detach_breakpoints would take a pid, and then
set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid).
Unfortunately, this ptid is not necessarily valid.  Consider for
instance the case of ia64-hpux, where ttrace refuses a register-read
operation if the LWP is not provided.

This problems shows up when GDB is trying to handle fork events.
Assuming GDB is configured to follow the parent, GDB will try to
detach from the child. But before doing so, it needs to remove
all breakpoints inside that child.  On ia64, this involves reading
inferior (the child's) memory. And on ia64-hpux, reading memory
requires us to read the bsp and bspstore registers, in order to
determine where that memory is relative to the value of those
registers, and thus to determine which ttrace operation to use in
order to fetch that memory (see ia64_hpux_xfer_memory).

This patch therefore changes detach_breakpoints to take a ptid instead
of a pid, and then updates all callers.

One of the consequences of this patch is that it trips an assert
on GNU/Linux targets.  But this assert appears to have not actual
purpose, and is thus removed.

gdb/ChangeLog:

        * breakpoint.h (detach_breakpoints): pid parameter is now a ptid.
        * breakpoint.c (detach_breakpoints): Change pid parameter into
        a ptid.  Adjust code accordingly.
        * infrun.c (handle_inferior_event): Delete variable child_pid.
        Update call to detach_breakpoints to pass the child ptid for
        fork events.
        * linux-nat.c (linux_nat_iterate_watchpoint_lwps): Remove
        assert that inferior_ptid's lwp is zero.
        (linux_handle_extended_wait): Update call to detach_breakpoints.
        * inf-ttrace.c (inf_ttrace_follow_fork): Update call to
        detach_breakpoints.
