 I'd like to xfail the test for irix then.
 
 But if as you say it works for gas, is there a way to only xfail it
 when using the native assembler e.g.  using
 compiler_conditional_xfail_data?  (Not sure how to do that yet.)
 
 Or maybe we just don't assemble for either as/gas if we're on irix via
 set options "-S".
 
 Thoughts?

 That'd be ok I guess.

    Not really a bug.  Your system assembler doesn't support
