Pierre Langlois 6b940e6a06 Remove isize output argument from fast_tracepoint_valid_at
This patch removes the isize output argument from the
fast_tracepoint_valid_at gdbarch hook.  It was used to return the size
of the instruction that needs to be replaced when installing a fast
tracepoint.  Instead of getting this value from the
fast_tracepoint_valid_at hook, we can call the gdb_insn_length function.

If we do not do this, then architectures which do not have a restriction
on where to install the fast tracepoint will send uninitialized memory
off to GDBserver.  See remote_download_tracepoint:

~~~
int isize;

if (gdbarch_fast_tracepoint_valid_at (target_gdbarch (),
				      tpaddr, &isize, NULL))
  xsnprintf (buf + strlen (buf), BUF_SIZE - strlen (buf), ":F%x",
	     isize);
~~~

The default implementation of fast_tracepoint_valid_at will not set
isize resulting in uninitialized memory being sent.  Later on, GDBserver
could use this information to compute a jump offset.

gdb/ChangeLog:

	* arch-utils.c (default_fast_tracepoint_valid_at): Remove unused
	isize argument.
	* arch-utils.h (default_fast_tracepoint_valid_at): Likewise.
	* breakpoint.c (check_fast_tracepoint_sals): Adjust call to
	gdbarch_fast_tracepoint_valid_at.
	* gdbarch.sh (fast_tracepoint_valid_at): Remove isize argument.
	* gdbarch.h: Regenerate.
	* gdbarch.c: Regenerate.
	* i386-tdep.c (i386_fast_tracepoint_valid_at): Remove isize
	argument.  Do not set it.
	* remote.c (remote_download_tracepoint): Adjust call to
	gdbarch_fast_tracepoint_valid_at.  Call gdb_insn_length to get
	the instruction length.

		   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.
