It'd be nice if somebody can confirm. Thanks, drew > +/* > + * ARMv7-A isn't exactly the same as ARMv8-A32 (AArch32).

Since the CPUID registers were introduced, the architecture goes to great lengths to not expose a version, and trying to guess from software is a losing battle. So I don't think we should try to distinguish ARMv8-A AArch32 from ARMv7-A. We should test individual features, or if that's not possible, group them in the same bucket.
