mn10300.c (can_use_return_insn): Add size of fixed stack space for function calls into the size of the frame.
* mn10300.c (can_use_return_insn): Add size of fixed stack space
for function calls into the size of the frame. */
(expand_prologue, expand_epilogue): Likewise.
(initial_offset): Corresponding changes..
* mn10300.h (OUTGOING_REG_PARM_STACK_SPACE): No longer define.
(STACK_POINTER_OFFSET): Define.
* mn10300.md (call, call_value expanders): Don't adjust the stack
pointer here anymore.
* mn10300.md (ashlsi3): Remove some alternatives which are no longer
needed or desired.
