We were missing feature checks for various parts of the 16-bit Thumb encoding space, with the result that we didn't UNDEF when we should for these on pre-v6T2 CPUs: * CBZ/CBNZ * IT * the "hint space" (which doesn't become NOPs until v6T2)
This patchset fixes up those mistakes so we UNDEF when the hardware does. M-profile makes this a little more complicated, so the precise test is different in the three cases. thanks -- PMM Peter Maydell (3): target/arm: Make CBZ/CBNZ UNDEF before v6T2 target/arm: Make IT insn undef when not present target/arm: Make Thumb T1 hint space UNDEF before v6T2 target/arm/tcg/t16.decode | 3 +++ target/arm/tcg/translate.c | 37 ++++++++++++++++++++++++++++++++++++- 2 files changed, 39 insertions(+), 1 deletion(-) -- 2.43.0
