Commit df8411da087dc05481926f4c4a82deabc5bc3859 implemented support for checking /proc/PID/coredump_filter, and also changed gcore behavior to unconditionally honor the VM_DONTDUMP flag, preventing sections marked as such for being dumped into the core file. This patch implements the 'set dump-excluded-mappings' command for instructing gdb to ignore the VM_DONTDUMP flag. Combined with 'set use-coredump-filter', this allows the user to restore the old behavior, dumping all sections (except the ones marked as IO) unconditionally. gdb/Changelog: 2017-11-29 Sergio Lopez <slp@redhat.com> * linux-tdep.c (dump_excluded_mappings): New variable. (dump_mapping_p): Use dump_excluded_mappings variable. (_initialize_linux_tdep): New command 'set dump_excluded_mappings'.
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.
