A problem occurs when a program running properly on a 32-bit machine fails on a 64-bit machine. So I found this article about transplantation and took a good look. Original post address: http://queniao.blog.51cto.com/10636/126564 In fact, there is

Instruction Set changes1. Address width and operand width prefixIn 64-Bit mode, the default address width is 64-bit, and the default operand width is 32-bit. The prefix of address width and operand width allows 32-bit and 64-bit data and addresses

TermsBefore discussing DB2's support for 32-bit and 64-bit, we will first view and understand some of the terms and important concepts involved in the context of this article. This is very important: Platform:The basic technologies of computer

Even if you haven't compiled advanced applications for nanoelectronics, aerodynamic, Molecular static, cell lifecycle modeling, and so on, maybe the following 32 rules are as follows, it will help you port programs to a higher-level

Communication between programs is actually sending and receiving data streams. We generally regard bytes as the smallest unit of data. Of course, a byte also contains 8 bits ). In a 32-bit processor, the "font length" is 32 bits, that is, 4 bytes.
