6cb5b585c5 * tic80-opc.c (tic80_predefined_symbols): Table of name/value
pairs for all predefined symbols recognized by the assembler.
	Also used by the disassembling routines.
	(tic80_symbol_to_value): New function.
	(tic80_value_to_symbol): New function.
	* tic80-dis.c (print_operand_control_register,
 	print_operand_condition_code, print_operand_bitnum):
	Remove private tables and use tic80_value_to_symbol function.

8fdffbc4b3 * tic80-dis.c (print_insn_tic80): Broke excessively long
function up into several smaller ones and arranged for
        the instruction printing function to be callable recursively
        to print vector instructions that have both a load and a
        math instruction packed into a single opcode.
        * tic80-opc.c (tic80_opcodes): Expand comment for vld opcode
        to explain why it comes after the other vector opcodes.

50965d0ec2 * tic80-dis.c (R_SCALED): Add macro to test for ":s" modifier bit.
(print_insn_tic80): If R_SCALED then print ":s" modifier for operand.
	* tic80-opc.c (REG0, REG22, REG27, SSOFF, LSOFF): Names
	changed to REG_0, REG_22, REG_DEST, OFF_SS, OFF_SL respectively.
	(SICR, LICR, REGM_SI, REGM_LI): Names changed to CR_SI, CR_LI,
	REG_BASE_M_SI, REG_BASE_M_LI respectively.
	(REG_SCALED, LSI_SCALED): New operand types.
	(E): New macro for 'E' bit at bit 27.
	(tic80_opcodes): Add and test dld, dld.u, dst, estop, and etrap
	opcodes, including the various size flavors (b,h,w,d) for
	the direct load and store instructions.

937fe72232 * tic80-dis.c (M_SI, M_LI): Add macros to test for ":m" modifier bit
in an instruction.
	* tic80-dis.c (print_insn_tic80): Change comma and paren handling.
  	Use M_SI and M_LI macros to check for ":m" modifier for GPR operands.
	* tic80-opc.c (tic80_operands): Add REGM_SI and REGM_LI operands.
	(F, M_REG, M_LI, M_SI, SZ_REG, SZ_LI, SZ_SI, D, S): New	bit-twiddlers.
	(MASK_LI_M, MASK_SI_M, MASK_REG_M): Remove and replace in opcode
	masks with "MASK_* & ~M_*" to get the M bit reset.
