John Baldwin 7efba073e2 Use signal information to determine SIGTRAP type for FreeBSD.
Use the signal code from siginfo_t to distinguish SIGTRAP events due
to trace traps (TRAP_TRACE) and software breakpoints (TRAP_BRKPT).
For software breakpoints, adjust the PC when the event is reported as
part of the API when supplying "stopped_by_sw_breakpoint".  Currently
FreeBSD only supports hardware watchpoints and breakpoints on x86
which are reported as trace traps.  Signal information is not used on
MIPS and sparc64 kernels which do not reliably report TRAP_BRKPT for
software breakpoints.

gdb/ChangeLog:

	* fbsd-nat.c: Include "inf-ptrace.h".
	(USE_SIGTRAP_SIGINFO): Conditionally define.
	[USE_SIGTRAP_SIGINFO] (fbsd_handle_debug_trap): New function.
	(fbsd_wait) [USE_SIGTRAP_SIGINFO]: Call "fbsd_handle_debug_trap".
	[USE_SIGTRAP_SIGINFO] (fbsd_stopped_by_sw_breakpoint): New
	function.
	[USE_SIGTRAP_SIGINFO] (fbsd_supports_stopped_by_sw_breakpoint):
	Likewise.
	[USE_SIGTRAP_SIGINFO] (fbsd_supports_stopped_by_hw_breakpoint):
	Likewise.
	(fbsd_nat_add_target) [USE_SIGTRAP_SIGINFO]: Set
	"stopped_by_sw_breakpoint", "supports_stopped_by_sw_breakpoint",
	"supports_stopped_by_hw_breakpoint" target methods.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
