    gas/
            PR binutils/30551
            * config/tc-riscv.c (md_atof): Use target_big_endian instead of
            TARGET_BYTES_BIG_ENDIAN.
            * testsuite/gas/riscv/float-be.d: New file.
            * testsuite/gas/riscv/float-le.d: New file.
            * testsuite/gas/riscv/float.s: New file.
