I had only tested SPECCPU2017\nIntrate before.\n\nSo instead could you update generic_branch_cost to 7 please. That patch would\nbe pre-approved for 17. For 16 I believe the branch is frozen and needs RM\napproval and don't think this meets the cutoff for inclusion.\n\nOtherwise it's OK for 16.2.\n\nThanks,\nTamar\n\nThanks,\nTamar\n\n> ---\n> gcc/config/aarch64/tuning_models/olympus.h | 10 +++++++++-\n> 1 file changed, 9 insertions(+), 1 deletion(-)\n> \n> diff --git a/gcc/config/aarch64/tuning_models/olympus.h\n> b/gcc/config/aarch64/tuning_models/olympus.h\n> index c83e35adc2b..fb90a9d4e2c 100644\n> --- a/gcc/config/aarch64/tuning_models/olympus.h\n> +++ b/gcc/config/aarch64/tuning_models/olympus.h\n> @@ -159,6 +159,14 @@ static struct cpu_vector_cost olympus_vector_cost =\n> &olympus_vec_issue_info /* issue_info */\n> };\n> \n> +/* Olympus costs for branch instructions. */\n> +static const struct cpu_branch_cost olympus_branch_cost =\n> +{\n> + 1, /* Predictable. */\n> + 3, /* Unpredictable. */\n> + 7, /* br_mispredict_factor. */\n> +};\n> +\n> /* Olympus prefetch settings (which disable prefetch). */\n> static cpu_prefetch_tune olympus_prefetch_tune =\n> {\n> @@ -533,7 +541,7 @@ static struct tune_params olympus_tunings =\n> &generic_armv9_a_addrcost_table,\n> &olympus_regmove_cost,\n> &olympus_vector_cost,\n> - &generic_branch_cost,\n> + &olympus_branch_cost,\n> &generic_approx_modes,\n> SVE_128, /* sve_width */\n> { 4, /* load_int. */\n> --\n> 2.43.0","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","gcc-patches@gcc.gnu.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","gcc-patches@gcc.gnu.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (1024-bit key;\n unprotected) header.d=arm.com header.i=@arm.com header.a=rsa-sha256\n header.s=selector1 header.b=dGmKHmhu;\n\tdkim=pass (1024-bit key) header.d=arm.com header.i=@arm.com\n header.a=rsa-sha256 header.s=selector1 header.b=dGmKHmhu;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=gcc.gnu.org\n (client-ip=2620:52:6:3111::32;
