Simple question for simple answer.
I just can't figure out how to clear the instruction cache properly on such architecture.
Did anyone use it?

Have you looked at what the _ARM® Architecture Reference Manual ARMv8, for ARMv8-A architecture profile_ says on the matter? – Michael Apr 19 '17 at 13:43

I found the answer by myself on the Internet. – Antonio Ken Iannillo Apr 20 '17 at 11:04

GCC provide this built-in function
__builtin___clear_cache (void* start, void* end)
that is automatically managed according to the architecture.
Parameters set the range of memory to cache, where start is inclusive and end is exclusive. Every time a new memory area with instructions to execute, the cache should be cleared for that area.
