From: Kyrylo Tkachov Date: Fri, 2 Oct 2020 14:23:19 +0000 (+0100) Subject: AArch64: Add neoversev1_tunings struct X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c8c77ed747abb61a7f3cf34f71539bc87a5d6c3c;p=gcc.git AArch64: Add neoversev1_tunings struct This patch adds a Neoverse V1-specific tuning struct that currently is just a deduplication of the N1 struct it was using before and specifying the SVE width. This will allow us to tweak Neoverse V1 things in the future as needed. Bootstrapped and tested on aarch64-none-linux-gnu. gcc/ * config/aarch64/aarch64.c (neoversev1_tunings): Define. * config/aarch64/aarch64-cores.def (zeus): Use it. (neoverse-v1): Likewise. --- diff --git a/gcc/config/aarch64/aarch64-cores.def b/gcc/config/aarch64/aarch64-cores.def index ac2a9b4cfe6..b2e1932d120 100644 --- a/gcc/config/aarch64/aarch64-cores.def +++ b/gcc/config/aarch64/aarch64-cores.def @@ -136,8 +136,8 @@ AARCH64_CORE("thunderx3t110", thunderx3t110, thunderx3t110, 8_3A, AARCH64_FL_ /* ARMv8.4-A Architecture Processors. */ /* Arm ('A') cores. */ -AARCH64_CORE("zeus", zeus, cortexa57, 8_4A, AARCH64_FL_FOR_ARCH8_4 | AARCH64_FL_SVE | AARCH64_FL_RCPC | AARCH64_FL_I8MM | AARCH64_FL_BF16 | AARCH64_FL_F16 | AARCH64_FL_PROFILE | AARCH64_FL_SSBS | AARCH64_FL_RNG, neoversen1, 0x41, 0xd40, -1) -AARCH64_CORE("neoverse-v1", neoversev1, cortexa57, 8_4A, AARCH64_FL_FOR_ARCH8_4 | AARCH64_FL_SVE | AARCH64_FL_RCPC | AARCH64_FL_I8MM | AARCH64_FL_BF16 | AARCH64_FL_F16 | AARCH64_FL_PROFILE | AARCH64_FL_SSBS | AARCH64_FL_RNG, neoversen1, 0x41, 0xd40, -1) +AARCH64_CORE("zeus", zeus, cortexa57, 8_4A, AARCH64_FL_FOR_ARCH8_4 | AARCH64_FL_SVE | AARCH64_FL_RCPC | AARCH64_FL_I8MM | AARCH64_FL_BF16 | AARCH64_FL_F16 | AARCH64_FL_PROFILE | AARCH64_FL_SSBS | AARCH64_FL_RNG, neoversev1, 0x41, 0xd40, -1) +AARCH64_CORE("neoverse-v1", neoversev1, cortexa57, 8_4A, AARCH64_FL_FOR_ARCH8_4 | AARCH64_FL_SVE | AARCH64_FL_RCPC | AARCH64_FL_I8MM | AARCH64_FL_BF16 | AARCH64_FL_F16 | AARCH64_FL_PROFILE | AARCH64_FL_SSBS | AARCH64_FL_RNG, neoversev1, 0x41, 0xd40, -1) /* Qualcomm ('Q') cores. */ AARCH64_CORE("saphira", saphira, saphira, 8_4A, AARCH64_FL_FOR_ARCH8_4 | AARCH64_FL_CRYPTO | AARCH64_FL_RCPC, saphira, 0x51, 0xC01, -1) diff --git a/gcc/config/aarch64/aarch64.c b/gcc/config/aarch64/aarch64.c index a3408f48c82..3cf20ea5ab7 100644 --- a/gcc/config/aarch64/aarch64.c +++ b/gcc/config/aarch64/aarch64.c @@ -1336,6 +1336,32 @@ static const struct tune_params neoversen1_tunings = &generic_prefetch_tune }; +static const struct tune_params neoversev1_tunings = +{ + &cortexa57_extra_costs, + &generic_addrcost_table, + &generic_regmove_cost, + &cortexa57_vector_cost, + &generic_branch_cost, + &generic_approx_modes, + SVE_256, /* sve_width */ + 4, /* memmov_cost */ + 3, /* issue_rate */ + (AARCH64_FUSE_AES_AESMC | AARCH64_FUSE_CMP_BRANCH), /* fusible_ops */ + "32:16", /* function_align. */ + "4", /* jump_align. */ + "32:16", /* loop_align. */ + 2, /* int_reassoc_width. */ + 4, /* 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. */ + &generic_prefetch_tune +}; + static const struct tune_params a64fx_tunings = { &generic_extra_costs,
