C++ (Cpp) DEF_r16w Examples

Example #1

static void PREFIX186(_imul_d8)(void)    /* Opcode 0x6b */
{
	DEF_r16w(dst,src);
	unsigned src2= (WORD)((INT16)((INT8)FETCH));

	ICOUNT -= (ModRM >= 0xc0) ? cycles.imul_rri8 : cycles.imul_rmi8;

	dst = (INT32)((INT16)src)*(INT32)((INT16)src2);
	I.CarryVal = I.OverVal = (((INT32)dst) >> 15 != 0) && (((INT32)dst) >> 15 != -1);
	RegWord(ModRM)=(WORD)dst;
}
