- The UNWIND_NULL_ID check in get_prev_frame_1 used to really be against null_frame_id, back before we had outer_frame_id. We didn't have UNWIND_OUTERMOST when outer_frame_id was added, but we do now, and it's more accurate. - It used to be necessary to check for the sentinel frame explicitly because that uses null_frame_id for frame id. Since no other frame can have that id nowadays (it's asserted by compute_frame_id), we don't need that explicit check. Tested on x86_64 Fedora 17. gdb/ 2013-11-28 Pedro Alves <palves@redhat.com> * frame.c (get_prev_frame_1): If the frame id is outer_frame_id, set the unwind stop reason to UNWIND_OUTERMOST, not UNWIND_NULL_ID. Remove explicit check for sentinel frame.
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.
