[PATCH]: Rewrite parts of CRX Assembler

[Tomer Levi]

Hi,

Since there are several parts in the CRX assembler port that are poorly 
written, I'm taking the opportunity to rewrite them.
The following patch starts this task - it provides a more generic operand 
parsing mechanism than the one used till now.
Tested successfully on the current testsuite.
I will commit these changes shortly.

2004-11-05  Tomer Levi  <Tomer.Levi@nsc.com>

        * opcode/crx.h (enum argtype): Rename types, remove unused types.

2004-11-05  Tomer Levi  <Tomer.Levi@nsc.com>

        * crx-opc.c (crx_optab): Rename 'arg_icr' to 'arg_idxr' for Index 
register mode.
        * crx-dis.c: Likewise.

2004-11-05  Tomer Levi  <Tomer.Levi@nsc.com>

        * config/tc-crx.c: Rename argument types.
        (processing_arg_number): Rename to 'cur_arg_num'.
        (get_number_of_bits): Rename to 'set_operand_size'.
        (get_operandtype): Rename to 'parse_operand', totally rewrite.
        (set_cons_rparams): Rename to 'set_operand', totally rewrite.
        (set_indexmode_parameters): Remove function, integrate its code 
into 'set_operand'.
        (set_operand_size): Get rid of 'Operand Number' function parameter 
- use global variable 'cur_arg_num' instead.
        Use a local 'argument' pointer to reference the current argument.
        (parse_operand): Likewise.
        (set_operand): Likewise.
        (process_label_constant): Likewise.
