I suspect the latter is the better option.
The .config linked from the report shows
CONFIG_AS_VERSION=23101 CONFIG_ARM64_PTR_AUTH_KERNEL=y CONFIG_AS_HAS_ARMV8_3=y
So it gets detected as supporting ARMv8.3. Is this the wrong conditional to check, or does it get misdetected for an unsupported assembler?
