We need to be careful with parsing optional stop reasons that start
with an hex character ("awatch", "core"), as GDBs that aren't aware of
them parse them as real numbers. That's silly of course, given that
there should be a colon after those magic "numbers". So if strtol on
"abbz:" doesn't return "first invalid char" pointing to the colon, we
know that "abbz" isn't really a register number. It must be optional
stop info we don't know about. This adjusts GDB to work that way,
removing the need for the special casing done upfront:
/* If this packet is an awatch packet, don't parse the 'a'
as a register number. */
if (strncmp (p, "awatch", strlen("awatch")) != 0
&& strncmp (p, "core", strlen ("core") != 0))
For as long as we care about compatibility with GDB 7.9, we'll need to
continue to be careful about this, so I added a comment.
Tested on x86_64 Fedora 20, native gdbserver.
gdb/ChangeLog:
2015-02-23 Pedro Alves <palves@redhat.com>
* remote.c (skip_to_semicolon): New function.
(remote_parse_stop_reply) <T stop reply>: Use it. Don't
special case the stop reasons that look like hex numbers
upfront. Instead handle real register numbers after matching
all the known stop reasons.

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.
