The main issue is that in AT&T syntax, you may need to add a suffix to an instruction to tell the assembler what size of instruction to use. In Intel syntax, this suffix should not be there. The other problem is
Inline Assembly is different in VC++ and gcc. VC uses Intel syntax while gcc uses AT&T syntax. Here we define the difference in syntax of AT&T and Intel's assembly. Source and Destination Ordering In AT&T syntax the source is always on the left, and the destination is always on the right...
GCC, the GNU C Compiler for Linux, usesAT&T/UNIXassembly syntax. Here we’ll be using AT&T syntax for assembly coding. Don’t worry if you are not familiar with AT&T syntax, I will teach you. This is quite different from Intel syntax. I shall give the major differences. Source-Destinati...

语法分析:检查代码是否符合 C++ 语法规则、构建抽象语法树 AST(Abstract Syntax Tree)。 语义分析:检查类型兼容性(函数的返回值和参数类型等)、变量的作用域和声明、函数调用等。 代码优化:计算常量表达式的结果、移除永远不会执行的代码、循环优化等。 详细处理:模板类或函数在编译时根据具体类型进行实例化,转换异常...
GCC Inline Assembly SyntaxAssembly language appears in two flavors : Intel Style & AT&T style. GNU C compiler i.e. GCC uses AT&T syntax and this is what we would use. Let us look at some of the major differences of this style as against the Intel Style.GCC 内联汇编语法汇编语言以两种风...
