C ! B ! A ! OP !Z!Y!X! + * +-----------------------------------------------+---------------+ + * + * Some opcodes accept a reg/const argument which is handled by allocating + * flags in the OP field, see DUK_BC_ISREG() and DUK_BC_ISCONST(). The + * following convention is shared by most opcodes, so that the compiler + * can handle reg/const flagging without opcode specific code paths: + * + * !3!3!2!2!2!2!2!2!2!2!2!2!1!1!1!1!1!1!1!1!1!1! ! ! ! ! ! ! ! ! ! ! + * !1!0!9!8!7!6!5!4!3!2!1!0!9!8!7!6!5!4!3!2!1!0!9!8!7!6!5!4!3!2!1!0! + * +-----------------------------------------------+---------------+ + * ! C ! B ! A ! OP !Y!X! + * +-----------------------------------------------+---------------+ + * + * X 1=B is const, 0=B is reg + * Y 1=C is const, 0=C is reg + * + * In effect OP, OP + 1, OP + 2, and OP + 3 are allocated from the + * 8-bit opcode space for a single logical opcode. The base opcode + * number should be divisible by 4. If the opcode is called 'FOO' + * the following opcode constants would be defined: + * + * DUK_OP_FOO 100 // base opcode number + * DUK_OP_FOO_RR 100 // FOO, B=reg, C=reg + * DUK_OP_FOO_CR 101 // FOO, B=const, C=reg + * DUK_OP_FOO_RC 102 // FOO, B=reg, C=const + * DUK_OP_FOO_CC 103 // FOO, B=const, C=const + * + * If only B or C is a reg/const, the unused opcode combinations can be + * used for other opcodes (which take no reg/const argument). However, + * such opcode values are initially reserved, at least while opcode space + * is available. For example, if 'BAR' uses B for a register field and + * C is a reg/const: + * + * DUK_OP_BAR 116 // base opcode number + * DUK_OP_BAR_RR 116 // BAR, B=reg, C=reg + * DUK_OP_BAR_CR_UNUSED 117 // unused, could be repurposed + * DUK_OP_BAR_RC 118 // BAR, B=reg, C=const + * DUK_OP_BAR_CC_UNUSED 119 // unused, could be repurposed + * + * Macro naming is a bit misleading, e.g. "ABC" in macro name but the + * field layout is concretely "CBA" in the register. + */ + +typedef duk_uint32_t duk_instr_t; + +#define DUK_BC_SHIFT_OP 0 +#define DUK_BC_SHIFT_A 8 +#define DUK_BC_SHIFT_B 16 +#define
