Added target function calls for SH, M32R and H8300.
Added some generic target-independant code for managing call-dummy frames. Wed Nov 27 10:32:14 1996 Michael Snyder <msnyder@cleaver.cygnus.com> * breakpoint.c: DELETE command will not delete CALL_DUMMY breakpoint. * blockframe.c: Add target-independant support for managing CALL_DUMMY frames on the host side. * frame.h: Declarations for generic CALL_DUMMY frame support. * h8300-tdep.c: Add target function calls using generic frame support. * config/h8300/tm-h8300.h: config for generic target function calls. start-sanitize-m32r * m32r-tdep.c: Add target function calls using generic frame support. * config/m32r/tm-m32r.h: config for generic target function calls. end-sanitize-m32r * sh-tdep.c: Add target function calls using generic frame support. * config/sh/tm-sh.h: config for generic target function calls. start-sanitize-v850 * v850-tdep.c: Add target function calls using generic frame support. * config/v850/tm-v850.h: config for generic target function calls. end-sanitize-v850 * valops.c: ADD PUSH_RETURN_ADDRESS so that it doesn't have to be done by PUSH_ARGUMENTS when there's no CALL_DUMMY.
