2023-12-29target/i386: introduce flags writeback mechanismPaolo Bonzini
ALU instructions can write to both memory and flags. If the CC_SRC* and CC_DST locations have been written already when a memory access causes a fault, the value in CC_SRC* and CC_DST might be interpreted with the wrong CC_OP (the one that is in effect before the instruction. Besides just using the wrong result for the flags, something like subtracting -1 can have disastrous effects if the current CC_OP is CC_OP_EFLAGS: this is because QEMU does not expect bits outside the ALU flags to be set in CC_SRC, and env->eflags can end up set to all-ones. In the case of the attached testcase, this sets IOPL to 3 and would cause an assertion failure if SUB is moved to the new decoder. This mechanism is not really needed for BMI instructions, which can only write to a register, but put it to use anyway for cleanliness. In the case of BZHI, the code has to be modified slightly to ensure that decode->cc_src is written, otherwise the new assertions trigger.

2023-11-27target/arm: Handle overflow in calculation of next timer tickPeter Maydell
In commit edac4d8a168 back in 2015 when we added support for the virtual timer offset CNTVOFF_EL2, we didn't correctly update the timer-recalculation code that figures out when the timer interrupt is next going to change state. We got it wrong in two ways: * for the 0->1 transition, we didn't notice that gt->cval + offset can overflow a uint64_t * for the 1->0 transition, we didn't notice that the transition might now happen before the count rolls over, if offset > count In the former case, we end up trying to set the next interrupt for a time in the past, which results in QEMU hanging as the timer fires continuously. In the latter case, we would fail to update the interrupt status when we are supposed to. Fix the calculations in both cases. The test case is Alex Bennée's from the bug report, and tests the 0->1 transition overflow case.

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.

2023-11-21target/ppc: Fix bugs in VSX_CVT_FP_TO_INT and VSX_CVT_FP_TO_INT2 macrosJohn Platts
The patch below fixes a bug in the VSX_CVT_FP_TO_INT and VSX_CVT_FP_TO_INT2 macros in target/ppc/fpu_helper.c where a non-NaN floating point value from the source vector is incorrectly converted to 0, 0x80000000, or 0x8000000000000000 instead of the expected value if a preceding source floating point value from the same source vector was a NaN. The bug in the VSX_CVT_FP_TO_INT and VSX_CVT_FP_TO_INT2 macros in target/ppc/fpu_helper.c was introduced with commit c3f24257e3c0. This patch also adds a new vsx_f2i_nan test in tests/tcg/ppc64 that checks that the VSX xvcvspsxws, xvcvspuxws, xvcvspsxds, xvcvspuxds, xvcvdpsxws, xvcvdpuxws, xvcvdpsxds, and xvcvdpuxds instructions correctly convert non-NaN floating point values to integer values if the source vector contains NaN floating point values.

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>
