<pre>Even though LLVM in version 11 supports A64FX systems, llvm-mca does not allow
me to run an analysis on a a64fx system without mcpu flag or in general with
"-mcpu=a64fx" flag since it interprets the micro-architecture as in-order CPU.
It returns:
"error: please specify an out-of-order cpu. 'a64fx' is an in-order cpu."</pre>
