Consider a gdb_load patch to call the gdb_file_cmd twice:
...
proc gdb_load { arg } {
if { $arg != "" } {
+ set res [gdb_file_cmd $arg]
+ if { $res != 0 } {
+ return $res
+ }
return [gdb_file_cmd $arg]
}
return 0
}
...
With this patch, I run into:
...
(gdb) kill^M
The program is not being run.^M
(gdb) ^M</outputs/gdb.dwarf2/multidictionary/multidictionary^M
<.dwarf2/multidictionary/multidictionary"? (y or n)
ERROR: Couldn't load outputs/gdb.dwarf2/multidictionary/multidictionary \
into gdb (timeout).
p 1^M
Please answer y or n.^M
<.dwarf2/multidictionary/multidictionary"? (y or n) n^M
Not confirmed.^M
(gdb) UNRESOLVED: gdb.dwarf2/multidictionary.exp: GDB is alive \
(got interactive prompt)
...
The problem is that the second file command results in a prompt, which is
normally handled by gdb_file_cmd, but not recognized because the initial part
of the prompt is scrolled out.
This in turn is caused by using gdb_spawn_with_cmdline_opts without a
subsequent "set width 0".
Fix this by avoiding gdb_spawn_with_cmdline_opts, and forcing -readline by
temporarily modifying GDBFLAGS instead.
Tested on x86_64-linux.

gdb_spawn_with_cmdline_opts.
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.
