Update gdb.UnwindInfo.add_saved_register to accept named keyword arguments. As part of this update we now use gdb_PyArg_ParseTupleAndKeywords instead of PyArg_UnpackTuple to parse the function arguments. By switching to gdb_PyArg_ParseTupleAndKeywords, we can now use 'O!' as the argument format for the function's value argument. This means that we can check the argument type (is gdb.Value) as part of the argument processing rather than manually performing the check later in the function. One result of this is that we now get a better error message (at least, I think so). Previously we would get something like: ValueError: Bad register value Now we get: TypeError: argument 2 must be gdb.Value, not XXXX It's unfortunate that the exception type changed, but I think the new exception type actually makes more sense. My preference for argument names is to use full words where that's not too excessive. As such, I've updated the name of the argument from 'reg' to 'register' in the documentation, which is the argument name I've made GDB look for here. For existing unwinder code that doesn't throw any exceptions nothing should change with this commit. It is possible that a user has some code that throws and catches the ValueError, and this code will break after this commit, but I think this is going to be sufficiently rare that we can take the risk here.

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.
