Binutils with MCST patches
a2077e2540
If you have "set follow-fork child" set, then if you do "info threads" right after a fork, and before the child reports any other event to GDB core, you'll see: (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 31875) "fork-plus-threa" (running) 2.1 process 31879 "fork-plus-threa" Selected thread is running. (gdb) The "Selected thread is running." bit is a bogus error. That was GDB trying to fetch the current frame of thread 2.1, because the external runnning state is "stopped", and then throwing an error because the thread is actually running. This actually affects all-stop + schedule-multiple as well. The problem here is that on a fork event, GDB doesn't update the external parent/child running states. New comprehensive test included. The "kill inferior 1" / "kill inferior 2" bits also trip on PR gdb/19494 (hang killing unfollowed fork children), which was fixed by the previous patch. gdb/ChangeLog: 2016-01-25 Pedro Alves <palves@redhat.com> PR threads/19461 * infrun.c (handle_inferior_event_1) <fork/vfork>: Update parent/child running states. gdb/testsuite/ChangeLog: 2016-01-25 Pedro Alves <palves@redhat.com> PR threads/19461 * gdb.base/fork-running-state.c: New file. * gdb.base/fork-running-state.exp: New file. |

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.
