汇编语言（王爽著）笔记

@v4lour

第一章 基础知识

汇编语言是直接在硬件上工作的编程语言，由以下3类指令组成：

• 汇编指令：机器码的助记符，有对应的机器码
• 伪指令：没有对应的机器码，由编译器执行

感谢ftiasch老师教导，参考了 https://async.icpc-camp.org/d/408-fft 和其他一些地方的东西

P = 1e9+7
Q = ceil(sqrt(P))
a, b为两个向量
c = convolution(a, b)

c系数取值为 [0, n*(P-1)^2] 的整数，若n*(P-1)^2的表示需要超过53 bits(double mantissa)则很可能会出错

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Some useful custom text objects for vim

Collection of my custom text objects I use quite often.

Numbers

Put it into your .vimrc:
