Not able to bind function in emscripten

由 谁都会走 提交于 2021-02-11 14:56:26
问题 I am trying to use emscripten to call my c/c++ function from js. For this, I am referring this tutorial : https://kripken.github.io/emscripten-site/docs/porting/connecting_cpp_and_javascript/embind.html#embind I am following the process mentioned in this article but lerp function is not getting exported to Module and I am getting TypeError: Module.lerp is not a function in my browser console. I am just using the files mentioned in this article without any modification but still failing to

Mapping Between LLVM IR and x86 Instructions

由 依然范特西╮ 提交于 2021-02-08 06:36:43
问题 Is there an easy way to map to LLVM instructions from their associated assembly instructions in the output binary? Given an instruction in an x86 binary, I would like to be able to determine with which LLVM IR instruction it is associated. One possibility would be to compile the binary with debug symbols turned on and then associate the instructions based off of source code line, but that seems like a hack and is prone to having a many-to-many mapping between x86 and LLVM IR when ideally it

Emitting a single IR bitcode File with LLVM LLD using CMake

由 强颜欢笑 提交于 2021-02-08 05:14:44
问题 I'm using Ubuntu 16.04 x86_64 and LLVM 5.0 and would like to compile a project to a single LLVM IR bitcode file using CMake. I know there is a way to do this using the GOLD Linker with the LLVM Plugin and add the CMake linker flags " -fuse-ld=gold -Wl,-plugin-opt=emit-llvm " and the CXX flag " -flto ". But when I try to compile the project with the LLVM LLD linker and the " -fuse-ld=lld -Wl,-plugin-opt=emit-llvm " respectively " -flto " Flag, the linker is generating a native executable and

llvm - How to implement print function in my language?

问题 I'm following llvm's tutorial for their own simple programming language "Kaleidoscope" and there's an obvious functionality in my language which this tutorial doesn't seem to cover. I simply want to print any double to standard output pretty much as C++ would do: std::cout << 5.0; my language would do something like print(5.0); Third chapter of llvm's tutorial covers function calls. The code they use is: Value *CallExprAST::codegen() { // Look up the name in the global module table. Function

How to enable a LLVM backend?

问题 I am using Archlinux and installed LLVM using the official package (using pacman -S llvm ). I'd like to use it with the wasm-32 backend (available according to the source code). However, this backend is not enabled on my computer: $ llc --version LLVM (http://llvm.org/): LLVM version 5.0.0 Optimized build. Default target: x86_64-unknown-linux-gnu Host CPU: skylake Registered Targets: aarch64 - AArch64 (little endian) aarch64_be - AArch64 (big endian) amdgcn - AMD GCN GPUs arm - ARM arm64 -

浅谈编译过程

女主宣言 笔者前端时间在运行一个组内 Swift 项目的时候，发现编译时间比较长。所以查了部分优化项目编译时间的资料（当然还有部分原因是自己的电脑配置比较低）。并打算记录2篇文章。第一篇文章主要记录关于编译过程的内容，第二篇文章记录笔者在优化 Swift 项目编译时间的一点尝试。 本文是第一篇关于编译过程的文章。笔者将本文中介绍编译过程相关的内容，本文会按如下几个部分展开。 PS：丰富的一线技术、多元化的表现形式，尽在“360云计算”，点关注哦！ 编译相关名词解释； 1.1 编译器 1.2 编译器架构 1.3 GCC 1.4 Clang 1.5 LLVM 编译过程简单了解； 2.1 词法分析； 2.2 语法分析； 2.3 语义分析； 2.4 生成中间代码； 2.5 优化中间代码； 2.6 生成目标代码； 用具体命令代码简单分析编译过程；首先名词解释部分，笔者会介绍编译器、GCC、LLVM相关内容。 一、 名词解释 1. 编译器 编译器不是硬件，是可以把源程序编译为目标程序的计算机程序。 编译器 （compiler）是一种计算机程序，它会将某种编程语言写成的源代码（原始语言）转换成另一种编程语言（目标语言）。引自维基百科编译器 编译器功能示意图 2. 编译器架构 编译器架构： 2.1 Frontend：前端 词法分析、语法分析、语义分析、生成中间代码（汇编指令） 2.2

小白学PYTHON时最容易犯的6个错误

由 十年热恋 提交于 2021-02-01 02:44:30
最近又在跟之前的同学一起学习python，一起进步，发现很多测试同学在初学python的时候很容易犯一些错误，特意总结了一下。其实这些错误不仅是在学python时会碰到，在学习其他语言的时候也同样会碰到。 错误1：缩进 python是强制缩进的语言，很多同学在初次接触python时可能会不习惯，缩进老是犯错。比如 Python 2.7.12 (default, Sep 17 2016, 13:47:40) [GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.38)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> good = "ok" File "<stdin>", line 1 good = "ok" ^ IndentationError: unexpected indent 这种错误一般会提示IndentationError，最后根据错误所在行一般都能够很快的解决问题。 错误2: 中英文符号 很多初学者是分不清中英文符号的区别的，比如说:这是英文的冒号，而：这个冒号是中文的。乍一看长得差不多，但实际上确实不同的字符。比如 >>> x = 0>>> if x == 1： File "<stdin>",
