From: William Schmidt <wschmidt@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc(refs/users/wschmidt/heads/builtins10)] rs6000: Debug support Date: Mon, 26 Apr 2021 20:52:36 +0000 (GMT) [thread overview] Message-ID: <20210426205236.923BD3860C32@sourceware.org> (raw) https://gcc.gnu.org/g:edee3119cd0d656c2b30114b5d64af4a83607ddb commit edee3119cd0d656c2b30114b5d64af4a83607ddb Author: Bill Schmidt <wschmidt@linux.ibm.com> Date: Thu Apr 1 14:40:08 2021 -0500 rs6000: Debug support 2021-04-01 Bill Schmidt <wschmidt@linux.ibm.com> gcc/ * config/rs6000/rs6000-call.c (rs6000_debug_type): 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.
