2024-07-30tests/tcg: Use --noexecstack with assembler filesRichard Henderson
Add the --noexecstack assembler command-line option to avoid: /usr/bin/ld: warning: boot.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker which is enabled by default with current debian cross toolchains.

2024-06-12tests/tcg/s390x: Allow specifying extra QEMU options on the command lineIlya Leoshkevich
The use case for this is `make check-tcg EXTFLAGS="-accel kvm"`, which allows validating the system TCG testcases on real hardware. EXTFLAGS name is borrowed from tests/tcg/xtensa/Makefile.softmmu-target. While at it, use += instead of = in order to be consistent with the other architectures.

2023-11-23tests/tcg: finesse the registers check for "hidden" regsAlex Bennée
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 Bennée
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>

2023-06-29pc-bios/s390-ccw: Move the stack array into start.SThomas Huth
The stack array is only referenced from the start-up code (which is shared between the s390-ccw.img and the s390-netboot.img), but it is currently declared twice, once in main.c and once in netmain.c. It makes more sense to declare this in start.S instead - which will also be helpful in the next patch, since we need to mention the .bss section in start.S in that patch. While we're at it, let's also drop the huge alignment of the stack, since there is no technical requirement for aligning it to page boundaries.
