When $use_gdb_stub is true then, when we start an MI target there's a
regexp to match GDB's startup pattern. Unfortunately the pattern is
broken, and we're also missing a timeout case in the match list (which
would have helped point out that the regexp was broken).
The changes to the regexp are:
1. Remove '${run_match}' prefix, the issued command doesn't include
'${run_prefix}' so expecting '${run_match}' is wrong.
2. Replaced '\\n' with '\\\\n' in order to match literal '\n' in
GDBs output (that is, match a backslash followed by 'n', not a
newline character).
3. Replaced a '.' (matching any character) with '\.' to match a '.'
and moved the '\.' into the correct place in the regexp.
4. Replaced '\r\n' with '[\r\n]+' to match the end of a line. This
change isn't esential, but matches the other end of line patterns
within this regexp.
Here's an example of the output that the regexp should match taken
from a testfile log, the first line is the command sent to GDB, and
the remaining lines are the response from GDB:
jump *_start
&"jump *_start\n"
~"Continuing at 0x10074.\n"
^running
*running,thread-id="all"
(gdb)
gdb/testsuite/ChangeLog:
* lib/mi-support.exp (mi_run_cmd_full): Fix regexp and add a
timeout.
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.
