Implement frame apply [all | COUNT | -COUNT | level LEVEL... ] [FLAG]... COMMAND.
Also implement the command 'faas COMMAND', a shortcut for
'frame apply all -s COMMAND'.
The syntax of 'frame apply' to specify some innermost or outermost
frames is similar to 'backtrace' command, using COUNT or -COUNT.
To apply a COMMAND to a more specific set of frames, the following
new command and syntax can be used:
frame apply level LEVEL... [FLAG]... COMMAND
where LEVEL is one or more frame levels or range of frame levels.
The new command 'frame apply' allows to apply a COMMAND to a number of frames,
or to all frames, or to a set of frames.
The optional [FLAG]... arguments allow to control what output to produce
and how to handle errors raised when applying COMMAND to a frame.
Some example usages for this new command:
frame apply all info frame
Produce info frame for all frames.
frame apply all p $sp
For each frame, print the location, followed by the frame sp.
frame apply all -q p $sp
Same as before, but -q flag (q = quiet) indicates to only print
the frames sp.
frame apply all p some_local_var_somewhere
Print some_local_var_somewhere in all frames. 'frame apply'
will abort as soon as the print command fails.
frame apply all -c p some_local_var_somewhere
Same as before, but -c flag (c = continue) means to
print the error and continue applying command in case the
print command fails.
frame apply all -s p some_local_var_somewhere
Same as before, but -s flag (s = silent) means to
be silent for frames where the print command fails.
In other words, this allows to 'search' the frame in which
some_local_var_somewhere can be printed.
frame apply all -s -q p some_local_var_somewhere
Same as before, but does not print the frame info in which
the variable is found.
frame apply level 2-4 5 8-10 -s p i = i + 1
Increments i in the identified frames.

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.
