Hi Matthias,

Is there a corresponding binutils PR for this ?

Would the attached patch solve the problem ?

If the need for an executable stack is restricted to the hard-float ABI,
is there a way to determine this from the target configuration triplet ?

Is there an explanation somewhere of why the hard-float ABI needs an
executable stack - and possibly how this need might be removed ?

Cheers
