details:   https://anonhg.NetBSD.org/src/rev/3f2786be7d5c
branches:  trunk
changeset: 467369:3f2786be7d5c
user:      drochner <drochner%NetBSD.org@localhost>
date:      Tue Mar 23 21:29:03 1999 +0000

description:
Add a macro to check for sufficient pointer alignment in bus.h context,
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)
