From f1e247d0181d3b055b0d9435a7f65e88792e7812 Mon Sep 17 00:00:00 2001 From: Andrew Pinski Date: Wed, 21 Jun 2017 15:35:14 +0000 Subject: [PATCH] aarch64-cores.def (thunderxt88p1): Use thunderxt88 tunings. 2017-06-21 Andrew Pinski * config/aarch64/aarch64-cores.def (thunderxt88p1): Use thunderxt88 tunings. (thunderxt88): Likewise. * config/aarch64/aarch64.c (thunderxt88_prefetch_tune): New variable. (thunderx_prefetch_tune): New variable. (thunderx2t99_prefetch_tune): Update for the correct values. (thunderxt88_tunings): New variable. (thunderx_tunings): Use thunderx_prefetch_tune instead of generic_prefetch_tune. (thunderx2t99_tunings): Use AUTOPREFETCHER_WEAK.
