Hi!

On ASUS Tinker board, running Armbian (gcc version 8.3.0) -mcpu=native gives: -mcpu=cortex-a12 instead of -mcpu=cortex-a17 which is what the SOC (RK3288) really is. At least that is what the documentation is saying. Is this a known bug or should I report it?


GCC simply looks at the contents of /proc/cpuinfo for this information. If that says you have a cortex-a12, then that is what GCC will report.

Cortex-a12 and cortex-a17 are essentially the same; I believe some vendors may have marketed the former under the name of the latter.

GCC treats the two identically, so it wouldn't change your code anyway.
