        * emit-rtl.c (init_emit): Remove ??? comment.
        * explow.c (get_dynamic_stack_size): Take known alignment of stack
        pointer + STACK_DYNAMIC_OFFSET into account in lieu of STACK_BOUNDARY.
        * config/sparc/sparc.h (INIT_EXPANDERS): In 32-bit mode, lower the
        alignment of 3 virtual registers to BITS_PER_WORD.

        * config/sparc/sparc.c (sparc_compute_frame_size): Simplify.
