以下使用GNU89的标准 1.内联的定义: 内联就是一个关键字inline加载函数定义处,告诉编译器在编译的时候请对这个函数调用的地方进行内联调用(这里说的请,编译器可以拒绝这个操作因为内联函数的失败) 2.内联函数的作用 内联是为了节约函数的调用开销而诞生的,我们在调用一
Macros are handled by the pre-compiler, and are thus guaranteed to be inlined. Macros are used for short operations and it avoids function call overhead. It can be used if any short operation is being done in program repeatedly. Function-like macros are very beneficial when the same block ...

C++引进了内联函数(inline function)的概念。 宏替换实质上是文字替换。内联函数与一般函数不同的是,在进行程序的编译时,编译器将内联函数的目标代码作拷贝并将其插入到调用内联函数的地方。 例1.7 内联函数的使用 #include "iostream.h" inline double circle(double r) {return 3.1416*r*r;} int main() ...
inline return-type function-name(parameters) { } 请记住,内联只是对编译器的请求,而不是命令。编译器可以忽略内联请求。在以下情况下,编译器可能不会执行内联:1.如果函数包含循环。(对于while,do-while)2.如果函数包含静态变量。3.如果函数是递归的。4.如果函数的返回类型不是void,并且return语句在函数体中不存...
核函数(Kernel Function)是Ascend C算子Device侧实现的入口。在核函数中,需要为在AI核上执行的代码规定要进行的数据访问和计算操作。 extern "C" __global__ __aicore__ void add_custom(__gm__ uint8_t* x, __gm__ uint8_t* y, __gm__ uint8_t* z);复制 上面这个是一个核函数声明的示例,...
复制 struct shared { static inline int i = 1; }; 然后,我们像这样使用它: chapter06/03-odr-success/one.cpp 代码语言:javascript 代码运行次数:0 运行 复制 #include <iostream> #include "shared.h" int main() { std::cout << shared::i << std::endl; } 剩下的两个文件two.cpp和CMakeList...
Inline templates appear as normal function calls in the C/C++ source code. When the source code program cc -O prog.c code.il and the file containing the inline template defining the function are compiled together, the compiler will insert the code from the inline template in place of the ...
when the function is called: inline void toggle_led(); The console text (command line and errors) follows: *** Build of configuration Debug for project MSP430-flash1 *** C:\Program Files (x86)\Texas Instruments\ccsv4\utils\gmake\gmake -k all 'Building...
