  "message": "RISC-V: Remove RV32EF conflict\n\nDespite that the RISC-V ISA Manual version 2.2 prohibited \"RV32EF\", later\nversions beginning with the version 20190608-Base-Ratified removed this\nrestriction.  Because the \u0027E\u0027 extension is still a draft, the author chose\nto *just* remove the conflict (not checking the ISA version).\n\nNote that, because RV32E is only used with a soft-float calling convention,\nthere\u0027s no valid official ABI for RV32EF.  It means, even if we can assemble\na program with -march\u003drv32ef -mabi\u003dilp32e, floating-point registers are kept\nin an unmanaged state (outside ABI management).\n\nThe purpose of this commit is to suppress unnecessary errors while parsing\nan ISA string and/or disassembling, not to allow hard-float with RVE.\n\nbfd/ChangeLog:\n\n\t* elfxx-riscv.c (riscv_parse_check_conflicts): Accept RV32EF\n\tbecause only older specifications disallowed it.\n\ngas/ChangeLog:\n\n\t* testsuite/gas/riscv/march-fail-rv32ef.d: Remove as not directly\n\tprohibited.\n\t* testsuite/gas/riscv/march-fail-rv32ef.l: Likewise.\n",
