Let's see what the issue is. + +The user mentioned that qemu-arm isn't rejecting vrintz instructions on non-v8 CPUs like Cortex-A9. Vrintz is an ARM instruction that's specific to the v8 architecture, right? So if it's running on a CPU that doesn't support v8, QEMU should catch this and not execute the instruction. + +Looking at the details: When using objdump, they saw the instruction vrintz.f32, which should be v8-only. But when running under QEMU with -d in_asm, it shows an error about illegal width 64. Wait, but that's a bit confusing because the output suggests that QEMU did try to execute it but encountered an issue. + +Hmm, so is this a case where the instruction isn't being properly rejected beforehand? It seems like instead of rejecting it outright, QEMU attempted execution and then hit an error during translation or execution. That might mean there's a missing validation step in the code generation part. + +So the possible categories are things like mistranslation, assembly lowering, device, graphic, etc. Since this is about executing an instruction that shouldn't be supported on certain CPUs, it's related to how instructions are handled and translated when running under QEMU. + +Mistranslation usually refers to incorrect semantic mapping from the source architecture to the target or IR. In this case, maybe QEMU isn't correctly identifying that vrintz is a v8 instruction and allowing it to be executed on non-v8 CPUs. That sounds like an issue with how instructions are being translated or validated during the assembly lowering phase. + +Alternatively, could it be under 'assembly' category? Wait, 'assembly' in the options is listed as 'assembly lowering', which might refer to converting higher-level IR to machine code. But the problem here isn't about generating incorrect assembly; it's more about correctly handling (rejecting) certain instructions based on CPU features. + +Wait, so the issue is that QEMU should not even attempt to execute vrintz on a non-v8 CPU, but instead, it's trying and then failing. So this points to a problem in the translation or validation phase where such instructions are not being properly filtered out before execution. + +Therefore, I think 'mistranslation' is the right category because it involves the handling of instructions during the translation process from the source (ARM) to the target (emulated) architecture. If QEMU isn't correctly identifying that vrintz should be rejected on certain CPUs, it's a mistranslation or validation issue. +</think> + +mistranslation \ No newline at end of file |
