Hi,

This simple patch fixes in the AArch64 GAS the check of the system 
register parsing result.  With this fix, GAS can correctly issue 
diagnostics on unrecognized system registers in instructions like MSR, 
MRS, etc.

OK to commit?

Thanks,
Yufeng

result
          of function call 'parse_sys_reg' with 'PARSE_FAIL' instead of 
'FALSE'.
