在LLVM中,IR有三种表示,一种是可读的IR,类似于汇编代码,但其实它介于高等语言和汇编之间,这种表示就是给人看的,磁盘文件后缀为.ll;第二种是不可读的二进制IR,被称作位码(bitcode),磁盘文件后缀为.bc;第三种表示是一种内存格式,只保存在内存中,所以谈不上文件格式和文件后缀,这种格式是LLVM之所以编译快的一个...
LLVM IR是LLVM架构中一个重要的组成成分,编译器前端将抽象语法树转变为LLVM IR,而编译器后端则根据LLVM IR进行优化,生成可执行程序。但是,目前对LLVM IR的中文介绍少之又少。因此,我就写了这样的一系列文章,介绍了LLVM的架构,并且从LLVM IR的层面,让大家系统地了解LLVM。最近(2023年6月),这个GitHub仓库的star数...
最后就是编写pass了,pass本质上也是一个c++,创建Print_FuncPass.cpp,内容如下 #include"llvm/Pass.h"#include"llvm/IR/Function.h"#include"llvm/Support/raw_ostream.h"#include"llvm/IR/LegacyPassManager.h"#include"llvm/Transforms/IPO/PassManagerBuilder.h"usingnamespacellvm;namespace{structHello:publicFun...
along with code generation support for many popular CPUs (as well as some less common ones!) These libraries are built around a well specified code representation known as the LLVM intermediate representation ("LLVM IR"). The LLVM Core libraries are well documented, and it is particularly easy ...
第二个步骤,就是根据内存中的抽象语法树AST生成LLVM IR中间代码(有的比较新的编译器还会先将AST转化为MLIR再转化为IR)。 我们知道,我们写编译器的最终目的,是将源代码交给LLVM后端处理,让LLVM后端帮我们优化,并编译到相应的平台。而LLVM后端为我们提供的中介,就是LLVM IR。我们只需要将内存中的AST转化为LLVM IR...

LLVM IR LLVM的中间代码(IR)有以下3种表示方式, text:便于阅读的文本格式,类似于汇编语言,拓展名.ll, $ clang -S -emit-llvm main.m memory:内存格式 bitcode:二进制格式,拓展名.bc,clang -c -emit-llvm main.m LLVM和Clang在Xcode中的应用
