* m10300-dis.c (disassemble): Negate negative accumulator's shift. 2000-05-24 Alexandre Oliva <aoliva@cygnus.com> * m10300-dis.c (disassemble, case FSREG, FDREG): Don't assume 32-bit longs when sign-extending operands. 2000-04-20 Alexandre Oliva <aoliva@cygnus.com> * m10300-opc.c: Remove MN10300_OPERAND_RELAX from all FSREGs. * m10300-dis.c (HAVE_AM33_2): Define. (disassemble): Use it. (HAVE_AM33): Redefine. (print_insn_mn10300): Fix mask for 5-byte extended insns. 2000-04-01 Alexandre Oliva <aoliva@cygnus.com> * m10300-opc.c: Renamed AM332 to AM33_2. 2000-03-31 Alexandre Oliva <aoliva@cygnus.com> * m10300-opc.c: Defined AM33 2.0 register operands. Added support for AM33 2.0 `imm8,(abs16)' addressing mode for btst, bset and bclr. Implemented `fbCC', `flCC', `dcpf' and all FP insns. * m10300-dis.c (print_insn_mn10300): Recognize 5byte extended insn code of AM33 2.0. (disassemble): Recognize FMT_D3. Print out FP register names.
