I agree. The only -mcall option I've ever used is -mcall-aixdesc to generate the old dot-symbol function descriptors on powerpc64-linux. The eabi/noeabi options might also be useful, but I don't see the point of the ones that pretend to generate code for another OS. -- Alan Modra Australia Development Lab, IBM
