* 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.
