ARM汇编程序特点:
l 所有运算处理都是发生通用寄存器(一般是R0~R14)的之中.所有存储器空间(如C语言变量的本质就是一个存储器空间上的几个BYTE).的值的处理,都是要传送到通用寄存器来完成.因此代码中大量看到LDR,STR指令来传送值.
l ARM汇编语句中.当前语句很多时候要隐含的使用上一句的执行结果.而且上一句的执行结果,是放在CPSR寄存器里,(比如说进位,为0,为负…)-The ARM assembler FEATURES: l all arithmetic processing is a general-purpose registers (R0 ~ R14) is generally among all memory space (such as the nature of the C language variable is a memory space on several BYTE).' s Value processing are to be transferred to the general-purpose registers to complete a large number to see the LDR, STR instruction code to send value l ARM assembler statements often implied the use of a result of the execution of the current statement and on a The execution result is placed in the CPSR (such as binary, to 0, negative, ...)
