4 daystests, scripts: Don't import print_function from __future__Peter Maydell7-7/+0
Some of our Python scripts still include the line from __future__ import print_function which is intended to allow a Python 2 to handle the Python 3 print() syntax. This particular part of the future arrived many years ago, and our minimum Python version is 3.9, so we don't need to keep this line around. NB: the scripts in tests/tcg/*/gdbstub/ are run with whatever Python gdb was built against, but we can safely assume that that was a Python 3 because our supported distros are all on Python 3. In any case these are only run as part of "make check-tcg", not by end-users.

GDB 15 does not like exit() anymore: (gdb) python exit(0) Python Exception <class 'SystemExit'>: 0 Error occurred in Python: 0 Use the GDB's own exit command, like it's already done in a couple places, everywhere.

2023-11-23tests/tcg: finesse the registers check for "hidden" regsAlex Bennée1-26/+69
The reason the ppc64 and s390x test where failing was because gdb hides them although they are still accessible via regnum. We can re-arrange the test a little bit and include these two arches in our test. We also need to be a bit more careful handling remote-registers as the format isn't easily parsed with pure white space separation. Once we fold types like "long long" and "long double" into a single word we can now assert all registers are either listed or elided.

2023-11-08tests/tcg: add an explicit gdbstub register testerAlex Bennée1-0/+197
We already do a couple of "info registers" for specific tests but this is a more comprehensive multiarch test. It also has some output helpful for debugging the gdbstub by showing which XML features are advertised and what the underlying register numbers are. My initial motivation was to see if there are any duplicate register names exposed via the gdbstub while I was reviewing the proposed register interface for TCG plugins. Mismatches between the xml and remote-desc are reported for debugging but do not fail the test. We also skip the tests for the following arches for now until we can investigate and fix any issues: - s390x (fails to read v0l->v15l, not seen in remote-registers) - ppc64 (fails to read vs0h->vs31h, not seen in remote-registers) Cc: Akihiko Odaki <akihiko.odaki@daynix.com> Cc: Luis Machado <luis.machado@linaro.org> Cc: Ilya Leoshkevich <iii@linux.ibm.com> Cc: qemu-s390x@nongnu.org Cc: Nicholas Piggin <npiggin@gmail.com> Cc: Daniel Henrique Barboza <danielhb413@gmail.com> Cc: qemu-ppc@nongnu.org Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20231106185112.2755262-7-alex.bennee@linaro.org>

2023-08-30gdbstub: fixes cases where wrong threads were reported to GDB on SIGINTMatheus Branco Borella1-0/+97
This fix is implemented by having the vCont handler set the value of `gdbserver_state.c_cpu` if any threads are to be resumed. The specific CPU picked is arbitrarily from the ones to be resumed, but it should be okay, as all GDB cares about is that it is a resumed thread.
