(tic80_opcodes): Reorder table entries to put the 32 bit PC relative

Fred Fish c7583da0b6 * tic80-opc.c (tic80_predefined_symbols): Revert change to
store BITNUM values in the table in one's complement form
	to match behavior when assembler is given a raw numeric
	value for a BITNUM operand.
	* tic80-dis.c (print_operand_bitnum): Ditto.

Fred Fish e2773136e0 * tic80-opc.c (tic80_operands): Fix typo '+' -> '|'.
(tic80_opcodes): Sort entries so that long immediate forms

Fred Fish c37555c141 * tic80-opc.c (tic80_symbol_to_value): Changed to accept
a symbol class that restricts translation to just that
	class (general register, condition code, etc).
1997-02-10 17:16:28 +00:00
Fred Fish cceb79baa8 * tic80-opc.c (tic80_operands): Add REG_0_E, REG_22_E,
and REG_DEST_E for register operands that have to be
	an even numbered register.  Add REG_FPA for operands that
	are one of the floating point accumulator registers.
	Add TIC80_OPERAND_MASK to flags for ENDMASK operand.
	(tic80_opcodes): Change entries that need even numbered
	register operands to use the new operand table entries.

Fred Fish 1eb54bb463 * tic80-opc.c (tic80_opcodes): Expand comment to note that the
entries are presorted so that entries with the same mnemonic are
	adjacent to each other in the table.  Sort the entries for each
	instruction so that this is true.

Fred Fish 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.

Fred Fish c977d8fb7b * tic80-opc.c (V_a, V_m, V_S, V_Z, V_p, OP_V, MASK_V):
New macros for building vector instruction opcodes.
	(tic80_opcodes): Remove all uses of FMT_SI, FMT_REG, and
	FMT_LI, which were unused.  The field is now a flags field.
	Remove some opcodes that are possible, but illegal, such
	as long immediate instructions with doubles for immediate
	values.  Add "vadd" and "vld" instructions.
1997-01-17 04:00:56 +00:00
Fred Fish 5fdeceb477 * tic80-opc.c (tic80_operands): Reorder some table entries to make
the order more logical.  Move the shift alias instructions ("rotl",
	"shl", "ins", "rotr", "extu", "exts", "srl", and "sra" to be
 	interspersed with the regular sr.x and sl.x instructions.  Add
	and test new instruction opcodes for "sl", "sli", "sr", "sri", "st",
 	"sub", "subu", "swcr", and "trap".
