These three test all spawn a few threads and then send a SIGSTOP to their parent GDB in order to pause it while the new threads set things up for the test. With a GDB patch that changes the inferior thread's scheduling a bit, I sometimes see: FAIL: gdb.threads/siginfo-threads.exp: catch signal 0 (timeout) ... FAIL: gdb.threads/watchthreads-reorder.exp: reorder1: continue a (timeout) ... FAIL: gdb.threads/ia64-sigill.exp: continue (timeout) ... The issue is that the test program stops GDB before it had a chance of processing the new thread's clone event: (gdb) PASS: gdb.threads/siginfo-threads.exp: get pid continue Continuing. Stopping GDB PID 21541. Waiting till the threads initialize their TIDs. FAIL: gdb.threads/siginfo-threads.exp: catch signal 0 (timeout) On Linux (at least), new threads start stopped, and the debugger must resume them. The fix is to make the test program wait for the new threads to be running before stopping GDB. gdb/testsuite/ 2015-01-09 Pedro Alves <palves@redhat.com> * gdb.threads/ia64-sigill.c (threads_started_barrier): New global.

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.
