Remove the usage of inferior_list for the all_threads list in gdbserver. The entry field in thread_info is removed, and replaced by a simple ptid field. I added some functions to iterate (for_each_thread) and find threads (find_thread). However, changing all the users of find_inferior & co to use these new functions would have made the patch way too big. So I opted instead to make find_inferior & co some shims, so that the existing code only needs to be updated minimally. We can then update the existing code to use the new functions incrementally (I've started to do the work, but I'll post it afterwards, see [1] if you want a peek). This patch has been built-tested on all relevant platforms, except lynx. I also regtested using the native-gdbserver and native-extended-gdbserver boards on x86.

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.
