I noticed that faked_breakpoint is write only. And then I hacked win32_process_target::request_interrupt to force it to stop threads using the soft_interrupt_requested mechanism (which suspends threads, and then fakes a breakpoint event in the main thread), and saw that it no longer works -- gdbserver crashes accessing a NULL current_thread, because fake_breakpoint_event does not switch to a thread. This code was originally added for Windows CE, as neither GenerateConsoleCtrlEvent nor DebugBreakProcess worked there. We nowadays require Windows XP or later, and XP has DebugBreakProcess. The soft_interrupt_requested mechanism has other problems, like for example faking the event in the main thread, even if that thread was previously stopped, due to scheduler-locking. A following patch will add a similar mechanism stopping all threads with SuspendThread to native GDB, for non-stop mode, which doesn't have these problems. It's different enough from this old code that I think we should just rip the old code out, and reimplement it from scratch (based on gdb's version) when we need it.

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.
