java - Java 字节码助记符与 Jasmin 有何不同？

Question

Java 字节码助记符是 JVM 的类似于汇编的指令。Jasmin 在下面给出的链接中也被定义为 Java 汇编器。

Answer 1

Jasmin 是 assembler :

An assembler program creates object code by translating combinations of mnemonics and syntax for operations and addressing modes into their numerical equivalents. This representation typically includes an operation code ("opcode") as well as other control bits and data. The assembler also calculates constant expressions and resolves symbolic names for memory locations and other entities.[4] The use of symbolic references is a key feature of assemblers, saving tedious calculations and manual address updates after program modifications. Most assemblers also include macro facilities for performing textual substitution – e.g., to generate common short sequences of instructions as inline, instead of called subroutines.

因此，您使用 JVM 指令助记符编写一个软件程序，并使用 Jasmin 对其进行编译。

看看Jasmin User's Guide :

Jasmin is an assembler for the Java Virtual Machine. It takes ASCII descriptions of Java classes, written in a simple assembler-like syntax using the Java Virtual Machine instruction set. It converts them into binary Java class files, suitable for loading by a Java runtime system.
