This patch converts the SystemTap probe interface (gdb/stap-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 stap_probe' to 'class stap_probe', and a new 'class stap_static_probe_ops' to replace the use of 'stap_probe_ops'. Both classes implement the virtual methods exported by their parents, 'class probe' and 'class static_probe_ops', respectively. I believe it's now a bit simpler to understand the logic behind the stap-probe interface. There are several helper functions used to parse parts of a stap probe, and since they are generic and don't need to know about the probe they're working on, I decided to leave them as simple static functions (instead of e.g. converting them to class methods). I've also converted a few uses of "VEC" to "std::vector", which makes the code simpler and easier to maintain. And, as usual, some cleanups here and there. 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> Simon Marchi <simark@simark.ca> * stap-probe.c (struct probe_ops stap_probe_ops): Delete variable.

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.
