This adds an extra indirection when checking for the availability of an extension (compared to copying the fields into DisasContext). While not a performance problem today, we can always (shallow) copy the entire structure into the DisasContext (instead of putting a pointer to it) if this is ever deemed necessary.

Signed-off-by: Philipp Tomsich Reviewed-by: Richard Henderson Reviewed-by: Alistair Francis --- Changes in v6: - add the 'vt' prefix to gen_condmask, renaming it to gen_vt_condmask Changes in v3: - rename to trans_xventanacondops.c.inc (i.e. with the '.c') - (in MATERIALISE_EXT_PREDICATE) don't annotate the predicate function for testing the availability of individual extensions as 'inline' and don't make CPURISCVState* visible to these predicate functions Changes in v2: - Split off decode table into XVentanaCondOps.decode - Wire up XVentanaCondOps in the decoder-table target/riscv/XVentanaCondOps.decode | 25 ++++++++++++ target/riscv/cpu.c | 3 ++ target/riscv/cpu.h | 3 ++ .../insn_trans/trans_xventanacondops.c.inc | 39 +++++++++++++++++++ target/riscv/meson.build | 1 + target/riscv/translate.c | 12 ++++++ 6 files changed, 83 insertions(+) create mode 100644 target/riscv/XVentanaCondOps.decode create mode 100644 target/riscv/insn_trans/trans_xventanacondops.c.inc diff --git a/target/riscv/XVentanaCondOps.decode b/target/riscv/XVentanaCondOps.decode new file mode 100644 index 0000000000..5aef7c3d72 --- /dev/null +++ b/target/riscv/XVentanaCondOps.decode @@ -0,0 +1,25 @@ +# +# RISC-V translation routines for the XVentanaCondOps extension +# +# Copyright (c) 2022 Dr. Philipp Tomsich, philipp.tomsich@vrull.eu +# +# SPDX-License-Identifier: LGPL-2.1-or-later +# +# Reference: VTx-family custom instructions +# Custom ISA extensions for Ventana Micro Systems RISC-V cores +# (https://github.com/ventanamicro/ventana-custom-extensions/releases/download/v1.0.0/ventana-custom-extensions-v1.0.0.pdf) + +# Fields +%rs2 20:5 +%rs1 15:5 +%rd 7:5 + +# Argument sets +&r rd rs1 rs2 !extern + +# Formats +@r ....... ..... ..... ... ..... ....... &r %rs2 %rs1 %rd + +# *** RV64 Custom-3 Extension *** +vt_maskc 0000000 ..... ..... 110 ..... 1111011 @r +vt_maskcn 0000000 ..... ..... 111 ..... 1111011 @r diff --git a/target/riscv/cpu.c b/target/riscv/cpu.c index 1cb0436187..6df07b8289 100644 --- a/target/riscv/cpu.c +++ b/target/riscv/cpu.c @@ -734,6 +734,9 @@ static Property riscv_cpu_properties[] = { DEFINE_PROP_BOOL("zbc", RISCVCPU, cfg.ext_zbc, true), DEFINE_PROP_BOOL("zbs", RISCVCPU, cfg.ext_zbs, true), + /* Vendor-specific custom extensions */ + DEFINE_PROP_BOOL("xventanacondops", RISCVCPU, cfg.ext_XVentanaCondOps, false), + /* These are experimental so mark with 'x-' */ DEFINE_PROP_BOOL("x-j", RISCVCPU, cfg.ext_j, false), /* ePMP 0.9.3 */ diff --git a/target/riscv/cpu.h b/target/riscv/cpu.h index 1175915c0d..aacc997d56 100644 --- a/target/riscv/cpu.h +++ b/target/riscv/cpu.h @@ -329,6 +329,9 @@ struct RISCVCPUConfig { bool ext_zve32f; bool ext_zve64f; + /* Vendor-specific custom extensions */ + bool ext_XVentanaCondOps; + char *priv_spec; char *user_spec; char *bext_spec; diff --git a/target/riscv/insn_trans/trans_xventanacondops.c.inc b/target/riscv/insn_trans/trans_xventanacondops.c.inc new file mode 100644 index 0000000000..16849e6d4e --- /dev/null +++ b/target/riscv/insn_trans/trans_xventanacondops.c.inc @@ -0,0 +1,39 @@ +/* + * RISC-V translation routines for the XVentanaCondOps extension. + * + * Copyright (c) 2021-2022 VRULL GmbH. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms and conditions of the GNU General Public License, + * version 2 or later, as published by the Free Software Foundation. + * + * This program is distributed in the hope it will be useful, but WITHOUT + * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + * FITNESS FOR A PARTICULAR PURPOSE.
