* frv.opc (parse_uhi16): Fix handling of %hi operator on 64-bit
hosts. * cgen-asm.c (cgen_parse_signed_integer): Add code to handle the sign extension of negative values on a 64-bit host. * frv-asm.c: Regenerate. * gas/frv/immediates.s: New test file - checks assembly of constant values. * gas/frv/immediates.d: Expected disassmbly. * gas/frv/allinsn.exp: Run the new test.
