Vitis HLS supports the following C/C++ builtin functions: __builtin_clz(unsigned int x): Returns the number of leading 0-bits in x, starting at the most significant bit position. If x is 0, the result is undefined. __builtin_ctz(unsigned int x): Returns
gentype rotate(gentypev, gentype i); /* For each element in v, the bits are shifted left by the number of bits given by the corresponding element in i(subject to the usual shift modulo rules described in the “Shift Operators” subsection of “Vector Operators” in Chapter 4).Bits shi...
并且,我们也继续扩展 LAVL_FUN 类型来同时表示内建函数和自定义的函数,通过 lbuiltin 函数指针是否为 NULL 来进行区别。 struct lval { int type; /* Basic */ long num; char* err; char* sym; /* Function */ lbuiltin builtin; lenv* env; lval* formals; lval* body; /* Expression */ int...

笔记-python-built-in functions-eval,exec,compile 1. python代码执行函数有时需要动态改变代码,也就是说代码需要是字符串格式,然后在按需要编译,这时,需要一些执行代码的函数,js中的是eval(),python中也有类似内置函数。1.1. ev python不能滥用eval python 字符串 命名空间 python builtins用法 python built-in...
我们需要确保当调用find_package()时,CMake 能够发现这个查找模块,因此我们将这个路径添加到CMakeLists.txt中的CMAKE_MODULE_PATH变量里,用list(APPEND)。整个列表文件应该看起来像这样: chapter07/04-find-package-custom/CMakeLists.txt 代码语言:javascript 复制 cmake_minimum_required(VERSION 3.20.0) project(...
你可以通过在嵌套目录中的 listfile 添加 project() 命令来实现。只是不要忘记用 cmake_minimum_required() 它前缀。 由于支持项目嵌套,我们能否 somehow 连接并排构建的相关项目? 外部项目 技术上可以从一个项目到达另一个项目,CMake 也在一定程度上支持这一点。甚至还有一个 load_cache() 命令,允许你从另一个...
