WebA pseudo-op is an instruction to the assembler. A pseudo-operation, commonly called a pseudo-op, is an instruction to the assembler that does not generate any machine code. The assembler resolves pseudo-ops during assembly, unlike machine instructions, which are resolved only at runtime. Pseudo-ops are sometimes called assembler instructions, WebThis chapter describes, in detail, the syntax and usage rules of each assembler instruction. There is also information about assembly instructions on Conditional assembly instructions.The following table lists the assembler instructions by type, and provides the number of the page where the instruction is described. bitlife art

Todas as instruções da … The OR instruction is used for supporting logical expression by performing bitwise OR operation. The bitwise OR operator returns 1, if the matching bits from either or both operands are one. It returns 0, if both the bits are zero. For example, The OR operation can be used for setting one or more bits. For example, … Ver mais The AND instruction is used for supporting logical expressions by performing bitwise AND operation. The bitwise AND operation returns 1, if the matching bits from both the … Ver mais The NOT instruction implements the bitwise NOT operation. NOT operation reverses the bits in an operand. The operand could be either in a register or in the memory. For example, Ver mais The XOR instruction implements the bitwise XOR operation. The XOR operation sets the resultant bit to 1, if and only if the bits from … Ver mais The TEST instruction works same as the AND operation, but unlike AND instruction, it does not change the first operand.
