事实几乎如此——二进制文件包含了 CPU 执行的所有代码,但代码分散在多个文件中,方式非常复杂。链接是一个简化事物并使机器代码整洁、易于消费的过程。 快速查看命令列表会让你知道 CMake 并没有提供很多与链接相关的命令。承认,target_link_libraries()是唯一一个实际配置这一步骤的命令。那么为什么要用一整章来讲述...
一、入门指南 本书前半部分的大多数程序使用了 SDL 和 SSDL 的图形和游戏库, 1 理论上,观看彩色图形在屏幕上移动并互相射击比打印文本更有趣。别担心。当你完成后,你将能够用这个库或不用这个库来编写程序——如果我对此有什么要说的,你会从中得到乐趣。 如果你已经选择了你的平台,很好。如果没有,我的建议...

--no_rpt Prevents the compiler from generating repeat (RPT) instructions. By default, repeat instructions are generated for certain memcpy, division, and multiply-accumulate operations. However, repeat instructions are not interruptible. --protect_volatile=num Enables volatile reference protection. Pipelin...

问C++中的温度单位转换(C，F，K) -跟踪EN我将继续提供一个更简单版本的快速编写。我没有包括来自C++11或更高版本的任何“花哨”。我相信这可能会更简单或更好，但这只是一个开始。我忽略了额外的输出和输入验证，但您已经知道如何添加所有这些。我也没有太费心在这里命名，但你知道的。C++...

Avoid NaN result from fmal caused by multiply overflow when addend is infinity (-inf + inf results in NaN in that case). Picolibc version 1.8.2 Support _ZEPHYR_SOURCE macro which, like _POSIX_SOURCE et al, controls whether the library expresses the Zephyr C library API. This is also au...
The sine wave requires thesin()function, we can use the oscillator counter (phase), divide it by 255, and multiply by 2π. The resulting amplitude should be multiplied by 255 to get it as loud as the other oscillators becausesin()returns the values in the range [-1..1]. ...
In order to use these intrinsics, your code must include the stdlib.h header file. Prevents the compiler from generating repeat (RPT) instructions. By default, repeat instructions are generated for certain memcpy, division, and multiply-accumulate operations. However, repeat instructions ar...
