Commit a23e6a35d896a075640db714b28ce74bb6b8d7ff introduced a timer object to the WFMO handling in select_stuff::wait to allow sub-tickcount timeout values in select. Problems with this patch: The timer was created and destroyed on every invocation of select_stuff::wait, thus potentially multiple times per select. Also, since the timer was prepended to the WFMO hande list, the timer handle could shadow actual events on other objects, given that WFMO checks the objects in the order they have been specified in the HANDLE array. The timer was also created/destroyed and added to the HANDLE array even if it was not required. This patch drops the local timer HANDLE and recycles the cw_timer HANDLE in the cygtls area instead. Thus we typically don't need to create the timer in select at all, and we never have to destroy it. The timer HANDLE is now also appended as last object to the HANDLE array, and it's only added if actually needed. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
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.
