一、先看一下LEA这个指令,了解一下LEA英文的原意: Computes the effective address of the second operand (the source operand) and stores it in the first operand (destination operand). The source operand is a memory address (offset part) specified with one of the processors addressing modes; the d...
16 32 32-bit effective address is calculated. The lower 16 bits of the address are stored in the requested 16-bit register destination. 32 16 16-bit effective address is calculated. The 16-bit address is zero-extended and stored in the requested 32-bit register destination. 32 32 32-bit...
正确理解 LEAL (Load Effective Address) 指令 LEAL: leal S, D -> D ← &S 在CSAPP (Computer Systems: A Programmer’s Perspective) 中,对 LEAL 指令用作简单算术运算的情况,给出了一个例子: For example, if register %edx contains value x, leal 7(%edx,%edx,4), %eax will set register %eax...
在 CSAPP (Computer Systems: A Programmer’s Perspective) 中，对 LEAL 指令用作简单算术运算的情况，给出了一个例子：正确理解逻辑为：1. 设%edx的值为x 2. 7(%edx,%edx,4) 为变质寻址，目标内存地址为5x+7 3. 设储存在地址5x+7的值为y。然而LEAL并不寻址，它只取y的地址。y的地址即...
Editor's SummaryA costly drain on productivity, information overload can stem from not only vast amounts of information but also a failure to filter information as presented. Information architects (IAs) are in a position to address the challenge, starting by distinguishing between macro information...
Regardless of how fast the website loads, it will all be to no avail if the core functionality fails to perform as per user expectations. For optimal results, all testing, including unit tests, must be run on actual devices. Testing is only 100 percent effective when conducted underreal use...

CSAPP描述为: It has the form of an instruction that reads from memory to a register, but it does not reference memory at all. Its first operand appears to be a memory reference, but instead of reading from the designated location, the instruction copies the effective address to the destinati...
