We will use the C programming language in this chapter to explain inline assembler. It is possible to write assembly instructions in your C program. Most of the time this is not advisable, because the C compilers of today are so well-designed that you need to be a very skilled assembly programmer to improve upon the performance of C code. In fact, using inline assembly makes it more difficult for a C or C++ compiler to optimize the code containing your inline assembly.
Also, the C compiler will not do any error checking on your assembly instructions; you have to find out everything yourself. ...
