* gdbarch.sh (PUSH_DUMMY_CODE): New architecture method, add
comments noteing that it replaces the old FIX_CALL_DUMMY code.
* gdbarch.h, gdbarch.c: Re-generate.
* d10v-tdep.c (d10v_push_dummy_code): New function.
(d10v_gdbarch_init): Set push_dummy_code.
* infcall.c (legacy_push_dummy_code): New function.
(generic_push_dummy_code): New function.
(push_dummy_code): New function.
(call_function_by_hand): Call push_dummy_code. Pass bp_addr,
instead of dummy_addr, to push_dummy_call. Move call to
generic_save_call_dummy_addr to outside of CALL_DUMMY_LOCATION
switch.
* sparc-tdep.c (sparc_gdbarch_init): Mention push_dummy_code.
2003-05-03 Andrew Cagney <cagney@redhat.com>
* gdbint.texinfo (Target Architecture Definition): Document
push_dummy_code. Add cross references.
