--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> --- No idea, that has to be debugged. But I'd suggest in the two spots that cl_driver_no_arg is tested to add debugging printout of what the next argv is and whether CL_DRIVER is in lang_mask or not, and run it on arm as well as x86_64 and compare.
