This patch converts the generic probe interface (gdb/probe.[ch]) to C++, and also performs some cleanups that were on my TODO list for a while. The main changes were the conversion of 'struct probe' to 'class probe', and 'struct probe_ops' to 'class static_probe_ops'. The former now contains all the "dynamic", generic methods that act on a probe + the generic data related to it; the latter encapsulates a bunch of "static" methods that relate to the probe type, but not to a specific probe itself. I've had to do a few renamings (e.g., on 'struct bound_probe' the field is called 'probe *prob' now, instead of 'struct probe *probe') because GCC was complaining about naming the field using the same name as the class. Nothing major, though. Generally speaking, the logic behind and the design behind the code are the same. Even though I'm sending a series of patches, they need to be tested and committed as a single unit, because of inter-dependencies. But it should be easier to review in separate logical units. I've regtested this patch on BuildBot, no regressions found. gdb/ChangeLog: 2017-11-22 Sergio Durigan Junior <sergiodj@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use 'probe.prob' instead of 'probe.probe'. * breakpoint.c (create_longjmp_master_breakpoint): Call 'can_evaluate_arguments' and 'get_relocated_address' methods from probe.

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.
