Subject: [PATCH 14/18] rs6000: Debug support
Date: Wed, 1 Sep 2021 11:13:50 -0500 [thread overview]
Message-ID: <32347065c75ab5aa38fbc21c68ab6a5c56af49ee.1630511335.git.wschmidt@linux.ibm.com> (raw)

2021-07-28 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.
