From 02f21aea0679c5cac094a3f575e839d44cb57a39 Mon Sep 17 00:00:00 2001 From: Qian Jianhua Date: Mon, 3 Aug 2020 14:01:40 +0100 Subject: [PATCH] aarch64: Add A64FX machine model This patch add support for Fujitsu A64FX, as the first step of adding A64FX machine model. A64FX is used in FUJITSU Supercomputer PRIMEHPC FX1000, PRIMEHPC FX700, and supercomputer Fugaku. The official microarchitecture information of A64FX can be read at https://github.com/fujitsu/A64FX. 2020-08-03 Qian jianhua gcc/ * config/aarch64/aarch64-cores.def (a64fx): New core. * config/aarch64/aarch64-tune.md: Regenerated. * config/aarch64/aarch64.c (a64fx_prefetch_tune, a64fx_tunings): New. * doc/invoke.texi: Add a64fx to the list. --- gcc/config/aarch64/aarch64-cores.def | 3 +++ gcc/config/aarch64/aarch64-tune.md | 2 +- gcc/config/aarch64/aarch64.c | 37 ++++++++++++++++++++++++++++++++++++ gcc/doc/invoke.texi | 1 + 4 files changed, 42 insertions(+), 1 deletion(-) diff --git a/gcc/config/aarch64/aarch64-cores.def b/gcc/config/aarch64/aarch64-cores.def index bc89a14..a7dde38 100644 --- a/gcc/config/aarch64/aarch64-cores.def +++ b/gcc/config/aarch64/aarch64-cores.def @@ -119,6 +119,9 @@ AARCH64_CORE("octeontx2f95", octeontx2f95, cortexa57, 8_2A, AARCH64_FL_FOR_ AARCH64_CORE("octeontx2f95n", octeontx2f95n, cortexa57, 8_2A, AARCH64_FL_FOR_ARCH8_2 | AARCH64_FL_CRYPTO | AARCH64_FL_PROFILE, cortexa57, 0x43, 0x0b4, -1) AARCH64_CORE("octeontx2f95mm", octeontx2f95mm, cortexa57, 8_2A, AARCH64_FL_FOR_ARCH8_2 | AARCH64_FL_CRYPTO | AARCH64_FL_PROFILE, cortexa57, 0x43, 0x0b5, -1) +/* Fujitsu ('F') cores. */ +AARCH64_CORE("a64fx", a64fx, a64fx, 8_2A, AARCH64_FL_FOR_ARCH8_2 | AARCH64_FL_F16 | AARCH64_FL_SVE, a64fx, 0x46, 0x001, -1) + /* HiSilicon ('H') cores. */ AARCH64_CORE("tsv110", tsv110, tsv110, 8_2A, AARCH64_FL_FOR_ARCH8_2 | AARCH64_FL_CRYPTO | AARCH64_FL_F16 | AARCH64_FL_AES | AARCH64_FL_SHA2, tsv110, 0x48, 0xd01, -1) diff --git a/gcc/config/aarch64/aarch64-tune.md b/gcc/config/aarch64/aarch64-tune.md index 841af9d..ebf97c3 100644 --- a/gcc/config/aarch64/aarch64-tune.md +++ b/gcc/config/aarch64/aarch64-tune.md @@ -1,5 +1,5 @@ ;; -*- buffer-read-only: t -*- ;; Generated automatically by gentune.sh from aarch64-cores.def (define_attr "tune" - "cortexa34,cortexa35,cortexa53,cortexa57,cortexa72,cortexa73,thunderx,thunderxt88p1,thunderxt88,octeontx,octeontxt81,octeontxt83,thunderxt81,thunderxt83,emag,xgene1,falkor,qdf24xx,exynosm1,phecda,thunderx2t99p1,vulcan,thunderx2t99,cortexa55,cortexa75,cortexa76,cortexa76ae,cortexa77,cortexa65,cortexa65ae,ares,neoversen1,neoversee1,octeontx2,octeontx2t98,octeontx2t96,octeontx2t93,octeontx2f95,octeontx2f95n,octeontx2f95mm,tsv110,thunderx3t110,zeus,saphira,cortexa57cortexa53,cortexa72cortexa53,cortexa73cortexa35,cortexa73cortexa53,cortexa75cortexa55,cortexa76cortexa55" + "cortexa34,cortexa35,cortexa53,cortexa57,cortexa72,cortexa73,thunderx,thunderxt88p1,thunderxt88,octeontx,octeontxt81,octeontxt83,thunderxt81,thunderxt83,emag,xgene1,falkor,qdf24xx,exynosm1,phecda,thunderx2t99p1,vulcan,thunderx2t99,cortexa55,cortexa75,cortexa76,cortexa76ae,cortexa77,cortexa65,cortexa65ae,ares,neoversen1,neoversee1,octeontx2,octeontx2t98,octeontx2t96,octeontx2t93,octeontx2f95,octeontx2f95n,octeontx2f95mm,a64fx,tsv110,thunderx3t110,zeus,saphira,cortexa57cortexa53,cortexa72cortexa53,cortexa73cortexa35,cortexa73cortexa53,cortexa75cortexa55,cortexa76cortexa55" (const (symbol_ref "((enum attr_tune) aarch64_tune)"))) diff --git a/gcc/config/aarch64/aarch64.c b/gcc/config/aarch64/aarch64.c index a108119..7c3ab3e 100644 --- a/gcc/config/aarch64/aarch64.c +++ b/gcc/config/aarch64/aarch64.c @@ -868,6 +868,17 @@ static const cpu_prefetch_tune xgene1_prefetch_tune = -1 /* default_opt_level */ }; +static const cpu_prefetch_tune a64fx_prefetch_tune = +{ + 8, /* num_slots */ + 64, /* l1_cache_size */ + 256, /* l1_cache_line_size */ + 32768, /* l2_cache_size */ + true, /* prefetch_dynamic_strides */ + -1, /* minimum_stride */ + -1 /* default_opt_level */ +}; + static const struct tune_params generic_tunings = { &cortexa57_extra_costs, @@ -1325,6 +1336,32 @@ static const struct tune_params neoversen1_tunings = &generic_prefetch_tune }; +static const struct tune_params a64fx_tunings = +{ + &generic_extra_costs, + &generic_addrcost_table, + &generic_regmove_cost, + &generic_vector_cost, + &generic_branch_cost, + &generic_approx_modes, + SVE_512, /* sve_width */ + 4, /* memmov_cost */ + 7, /* issue_rate */ + (AARCH64_FUSE_AES_AESMC | AARCH64_FUSE_CMP_BRANCH), /* fusible_ops */ + "32", /* function_align. */ + "16", /* jump_align. */ + "32", /* loop_align. */ + 4, /* int_reassoc_width. */ + 2, /* fp_reassoc_width. */ + 2, /* vec_reassoc_width. */ + 2, /* min_div_recip_mul_sf. */ + 2, /* min_div_recip_mul_df. */ + 0, /* max_case_values. */ + tune_params::AUTOPREFETCHER_WEAK, /* autoprefetcher_model. */ + (AARCH64_EXTRA_TUNE_NONE), /* tune_flags. */ + &a64fx_prefetch_tune +}; + /* Support for fine-grained override of the tuning structures. */ struct aarch64_tuning_override_function { diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi index 060d73e..afe09a9 100644 --- a/gcc/doc/invoke.texi +++ b/gcc/doc/invoke.texi @@ -17354,6 +17354,7 @@ performance of the code.
