start-sanitize-m32r
Tue Nov 12 12:06:58 1996 Michael Snyder <msnyder@cleaver.cygnus.com> * m32r-tdep.c: Add functionality for target function calls. * valops.c: Small change to support target function calls. * config/m32r/tm-m32r.h: Add support for target function calls. This is a safety checkin -- everything works, but there'll be another clean-up round later.
