This patch resolves a couple of issues with the test case for SystemTap
user-space probe points:
1. The preprocessor macro guarding the semaphore variables in the C
file is (rather confusingly) named USE_PROBES. This has been
renamed to USE_SEMAPHORES, to better reflect its function.
2. The test procedures in the expect file improperly pass the flag
defining USE_PROBES to prepare_for_testing; as such, the test
binary that's supposed to have probes with semaphores is the same
as the one without. This has also been fixed.
3. No test is performed to check that `info probes' returns
information about probe semaphores. Such a test is included in this
patch.

2020-01-10 George Barrett <bob@bob131.so>
* gdb.base/stap-probe.c: Rename USE_PROBES to USE_SEMAPHORES.
* gdb.base/stap-probe.exp: Likewise.
(stap_test): Pass argument as an additional flag.
(stap_test_no_debuginfo): Likewise.
(stap_test): Check `info probes stap' output for semaphore
addresses if the test binary is supposed to have them.
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.
