Skeleton for disassembler support. * Makefile.in Remove v850 references, they're not needed here and they weren't being sanitized away. * configure.in: Add v850-dis.o when building v850 toolchains. * configure: Rebuilt. * disassemble.c (disassembler): Call v850 disassembler. --- opcodes/v850-dis.c | 78 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 78 insertions(+) create mode 100644 opcodes/v850-dis.c diff --git a/opcodes/v850-dis.c b/opcodes/v850-dis.c new file mode 100644 index 00000000000..3ee3959e9d0 --- /dev/null +++ b/opcodes/v850-dis.c @@ -0,0 +1,78 @@ +/* Disassemble V850 instructions. + Copyright (C) 1996 Free Software Foundation, Inc. + +This program is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
