More debug support; still not done
2020-04-10 Bill Schmidt <wschmidt@linux.ibm.com>
* gcc/config/rs6000/rs6000-call.c (rs6000_debug_type): New
function.
(def_builtin): Change format of debug output.
(altiec_init_builtins): Make pcvoid_type_node external.
* gcc/config/rs6000/rs6000.h (RS6000_BTI_const_ptr_void): New
rs6000_builtiin_type_index value.
(pcvoid_type_node): New #define.
