具体参加原文:https://www.ibiblio.org/gferg/ldp/GCC-Inline-Assembly-HOWTO.html#s1 概要 在讨论GCC内联汇编之前,我们先来搞搞清楚,到底什么是内联汇编? 先看在C语言中,我们可以指定编译器将一个函数代码直接复制到调用其代码的地方执行。这种函数调用方式和默认压栈调用方式不同,我们称这种函数为内联函数。内...

The result is that commonly a piece of gcc inline assembly will compile into a single asm instruction in the executable or library. (Often you just want access to a single instruction not exposed by C.) However, to do this, you need to understand how to craft the constraints told to the...

In my case, I do not use any assembler files, but there of course is inline assembly in different files (both nxp provided library, but also my own code has a few lines of assembly). I guess that results in the exact same problem, where my c++ code calls into assembly and cau...

Both these compilers implement the new standard behavior and have flags to enable backward compatibility to the inline behavior. Oracle® Developer Studio 12.6: GCC Compatibility Guide 8 GCC and Oracle Developer Studio have the options -fgnu89-inline and -xfeatures=extinl respectively. For more ...

The format of basic inline assembly is very much straight forward. Its basic form is 基本汇编嵌入格式如下: asm("assembly code"); Example. asm("movl %ecx %eax");/* moves the contents of ecx to eax */ __asm__("movb %bh (%eax)");/*moves the byte from bh to the memory pointed...
