The new gdbarch method, read_core_file_mappings, will be used for reading file-backed mappings from a core file. It'll be used for two purposes: 1) to construct a table of file-backed mappings in corelow.c, and 2) for display of core file mappings. For Linux, I tried a different approach in which knowledge of the note format was placed directly in corelow.c. This seemed okay at first; it was only one note format and the note format was fairly simple. After looking at FreeBSD's note/mapping reading code, I concluded that it's best to leave architecture specific details for decoding the note in (architecture specific) tdep files. With regard to display of core file mappings, I experimented with placing the mappings display code in corelow.c. It has access to the file-backed mappings which were read in when the core file was loaded. And, better, still common code could be used for all architectures. But, again, the FreeBSD mapping code convinced me that this was not the best approach since it has even more mapping info than Linux. Display code which would work well for Linux will leave out mappings as well as protection info for mappings. So, for these reasons, I'm introducing a new gdbarch method for reading core file mappings. gdb/ChangeLog: * arch-utils.c (default_read_core_file_mappings): New function. * arch-utils.c (default_read_core_file_mappings): Declare. * gdbarch.sh (read_core_file_mappings): New gdbarch method. * gdbarch.h, gdbarch.c: Regenerate.

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.
