The to_teardown_btrace target method is used to free btrace resources during shutdown when target record has already been unpushed and we can't reliably talk to a remote target to disable branch tracing. Tracing resources are freed for each thread when the thread is removed; both on the GDB side and on the gdbserver side. In the remote case, the remote target that provides to_teardown_btrace to free the GDB side resources has already been unpushed when threads are destroyed. This results in a complaint "You can't do this ..." and in a few bytes of memory leaked for each thread. Initiate btrace teardown in record_btrace_close, so the remote target is still in place. 2014-01-27 Markus Metzger <markus.t.metzger@intel.com> * record-btrace.c (record_btrace_close): Call btrace_teardown for all threads.
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.
