rs6000: Debug support for builtins changes
2021-11-09 Bill Schmidt <wschmidt@linux.ibm.com>
gcc/
* config/rs6000/rs6000-call.c (rs6000_type_string): New function.
(def_builtin): Change debug formatting for easier parsing and
include more information.
(rs6000_init_builtins): Add dump of autogenerated builtins.
(altivec_init_builtins): Dump __builtin_altivec_mask_for_load for
completeness.
