* xstormy16-tdep.c (xstormy16_scan_prologue): Add frameless
parameter. Set frameless flag if it exists and depended of whether the scanned function is frameless or not. (xstormy16_skip_prologue): If function is frameless, return result of xstormy16_scan_prologue(). (xstormy16_frame_init_saved_regs): Adjust xstormy16_scan_prologue() call.
