From: Nelson Chu Date: Thu, 26 Mar 2020 10:38:27 +0000 (+0800) Subject: RISC-V: Added half-precision floating-point v1.0 instructions. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=035784e3456d540444aaf7d8006f8e98bca79e5a;p=binutils-gdb.git RISC-V: Added half-precision floating-point v1.0 instructions. bfd/ * elfxx-riscv.c (riscv_implicit_subsets): Added implicit f and zicsr for zfh. (riscv_supported_std_z_ext): Added default v1.0 version for zfh. (riscv_multi_subset_supports): Handle INSN_CLASS_ZFH, INSN_CLASS_D_AND_ZFH and INSN_CLASS_Q_AND_ZFH. gas/ * config/tc-riscv.c (FLT_CHARS): Added "hH". (macro): Expand Pseudo M_FLH and M_FSH. (riscv_pseudo_table): Added .float16 directive. * testsuite/gas/riscv/float16-be.d: New testcase for .float16. * testsuite/gas/riscv/float16-le.d: Likewise. * testsuite/gas/riscv/float16.s: Likewise. * testsuite/gas/riscv/fp-zfh-insns.d: New testcase for zfh. * testsuite/gas/riscv/fp-zfh-insns.s: Likewise. include/ * opcode/riscv-opc.h: Added MASK and MATCH encodings for zfh. * opcode/riscv.h: Added INSN_CLASS and pseudo macros for zfh. opcodes/ * riscv-opc.c (riscv_opcodes): Added zfh instructions. --- diff --git a/bfd/elfxx-riscv.c b/bfd/elfxx-riscv.c index cb2cc146c04..05e8272e0e9 100644 --- a/bfd/elfxx-riscv.c +++ b/bfd/elfxx-riscv.c @@ -1100,6 +1100,8 @@ static struct riscv_implicit_subset riscv_implicit_subsets[] = {"zvl64b", "zvl32b", check_implicit_always}, {"d", "f", check_implicit_always}, {"f", "zicsr", check_implicit_always}, + {"zfh", "f", check_implicit_always}, + {"zfh", "zicsr", check_implicit_always}, {"zqinx", "zdinx", check_implicit_always}, {"zdinx", "zfinx", check_implicit_always}, {"zk", "zkn", check_implicit_always}, @@ -1180,6 +1182,7 @@ static struct riscv_supported_ext riscv_supported_std_z_ext[] = {"zifencei", ISA_SPEC_CLASS_20191213, 2, 0, 0 }, {"zifencei", ISA_SPEC_CLASS_20190608, 2, 0, 0 }, {"zihintpause", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, + {"zfh", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zfinx", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zdinx", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, {"zqinx", ISA_SPEC_CLASS_DRAFT, 1, 0, 0 }, @@ -2358,6 +2361,14 @@ riscv_multi_subset_supports (riscv_parse_subset_t *rps, case INSN_CLASS_Q_OR_ZQINX: return (riscv_subset_supports (rps, "q") || riscv_subset_supports (rps, "zqinx")); + case INSN_CLASS_ZFH: + return riscv_subset_supports (rps, "zfh"); + case INSN_CLASS_D_AND_ZFH: + return (riscv_subset_supports (rps, "d") + && riscv_subset_supports (rps, "zfh") ); + case INSN_CLASS_Q_AND_ZFH: + return (riscv_subset_supports (rps, "q") + && riscv_subset_supports (rps, "zfh")); case INSN_CLASS_ZBA: return riscv_subset_supports (rps, "zba"); case INSN_CLASS_ZBB: diff --git a/gas/config/tc-riscv.c b/gas/config/tc-riscv.c index fb3fc649802..1b730b4be36 100644 --- a/gas/config/tc-riscv.c +++ b/gas/config/tc-riscv.c @@ -389,7 +389,7 @@ const char EXP_CHARS[] = "eE"; /* Chars that mean this number is a floating point constant.
