UNRATIFIED RISC-V: Add 'Zfa' extension
[DO NOT MERGE] Until 'Zfa' extension is frozen/ratified and final version number is determined, this patch should not be merged upstream. This commit uses unratified version 0.1 as in the documentation (instead of possible 1.0 after ratification). This commit adds the 'Zfa' extension (its instructions and new operand type for FLI instructions). This is based on: <riscv/riscv-isa-manual@d74d99e>, latest 'Zfa' change on the master branch of the RISC-V ISA Manual as of this writing. Note: the author is calling FLI instructions' RS1 encoded field as "value". It must be reviewed before the specification is frozen. bfd/ChangeLog: * elfxx-riscv.c (riscv_multi_subset_supports): Add instruction class support for 'Zfa' extension. (riscv_multi_subset_supports_ext): Likewise. (riscv_implicit_subsets): Add 'Zfa' -> 'F' dependency. gas/ChangeLog: * testsuite/gas/riscv/zfa.s: New test. * testsuite/gas/riscv/zfa.d: Likewise. * testsuite/gas/riscv/zfa-32.s: New test. * testsuite/gas/riscv/zfa-32.d: Likewise. * testsuite/gas/riscv/zfa-64.s: New test. * testsuite/gas/riscv/zfa-64.d: Likewise. * testsuite/gas/riscv/zfa-fail.s: New failure test for 'Zfa' instructions. * testsuite/gas/riscv/zfa-fail.d: Likewise. * testsuite/gas/riscv/zfa-fail.l: Likewise. include/ChangeLog: * opcode/riscv-opc.h (MATCH_FLI_H, MASK_FLI_H, MATCH_FMINM_H, MASK_FMINM_H, MATCH_FMAXM_H, MASK_FMAXM_H, MATCH_FROUND_H, MASK_FROUND_H, MATCH_FROUNDNX_H, MASK_FROUNDNX_H, MATCH_FLTQ_H, MASK_FLTQ_H, MATCH_FLEQ_H, MASK_FLEQ_H, MATCH_FLI_S, MASK_FLI_S, MATCH_FMINM_S, MASK_FMINM_S, MATCH_FMAXM_S, MASK_FMAXM_S, MATCH_FROUND_S, MASK_FROUND_S, MATCH_FROUNDNX_S, MASK_FROUNDNX_S, MATCH_FLTQ_S, MASK_FLTQ_S, MATCH_FLEQ_S, MASK_FLEQ_S, MATCH_FLI_D, MASK_FLI_D, MATCH_FMINM_D, MASK_FMINM_D, MATCH_FMAXM_D, MASK_FMAXM_D, MATCH_FROUND_D, MASK_FROUND_D, MATCH_FROUNDNX_D, MASK_FROUNDNX_D, MATCH_FLTQ_D, MASK_FLTQ_D, MATCH_FLEQ_D, MASK_FLEQ_D, MATCH_FLI_Q, MASK_FLI_Q, MATCH_FMINM_Q, MASK_FMINM_Q, MATCH_FMAXM_Q, MASK_FMAXM_Q, MATCH_FROUND_Q, MASK_FROUND_Q, MATCH_FROUNDNX_Q, MASK_FROUNDNX_Q, MATCH_FLTQ_Q, MASK_FLTQ_Q, MATCH_FLEQ_Q, MASK_FLEQ_Q, MATCH_FCVTMOD_W_D, MASK_FCVTMOD_W_D, MATCH_FMVH_X_D, MASK_FMVH_X_D, MATCH_FMVH_X_Q, MASK_FMVH_X_Q, MATCH_FMVP_D_X, MASK_FMVP_D_X, MATCH_FMVP_Q_X, MASK_FMVP_Q_X): New. * opcode/riscv.h (enum riscv_insn_class): Add instruction classes for 'Zfa' extension. opcodes/ChangeLog: * riscv-opc.c (riscv_opcodes): Add 'Zfa' instructions.
