--- Comment #15 from Andrew Roberts <andrewm.roberts at sky dot com> --- Created attachment 42792 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42792&action=edit /proc/cpuinfo fro rpi3 (cortex a-53) on aarch64 /proc/cpuinfo fro rpi3 (cortex a-53) on aarch64 while this is the same cpu as odroid-c2 running aarch64, it has much newer kernel. rpi: 4.14.3-1-ARCH odroid-c2: 3.14.79-28-ARCH Newer aarch64 kernels expose MIDR directly at: /sys/devices/system/cpu/cpu0/regs/identification/midr_el1 but not the other control regs needed for FPU detection
