$ mkdir build $ cd build $ cmake -DLLVM_TARGETS_TO_BUILD="RISCVN" -DLLVM_USE_LINKER="lld" -DCMAKE_BUILD_TYPE=Debug -G Ninja ../llvm/ $ ninja 三、效果验证 3.1 编译器后端注册验证 进入目录build/bin,执行如下命令: $ ./llc --version 输出结果如下: LLVM (http://llvm.org/): LLVM...
由于全部构建真的很耗费资源和时间,我使用的构建clang命令(可供参考): $ cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86"-DLLVM_ENABLE_PROJECTS=clang -DLLVM_USE_LINKER=gold -G"Unix Makefiles"../llvm 当然你如果愿意(而且设备跑得动)也可以: $ cmake -G"Unix Makefiles"../llv...
5. 执行 cmake ../llvm cmake -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_LINKER=gold 1. 注意事项: 1.../llvm可能会存在问题,直接将../llvm改为LLVM 5.0源码所在位置,直接拖进去。譬如我自己的是 '/home/hzk/LLVM/llvm-5.0.0.src' 2.不要使用 Debug+Asserts ,如果是 ...
一个现代编译器的主要工作流程:源代码(source code) → 预处理器(preprocessor) → 编译器(compiler) → 目标代码(object code) → 链接器(Linker) → 可执行程序(executables) 源代码一般为高级语言(High-level language), 如C、C++、Java、Objective-C等或汇编语言,而目标则是机器语言的目标代码(Object copy)...
但是,IAR 的编译套件是支持命令行使用的 ,在其介绍文档中有这么一句话:The compiler, assembler, and linker can also be run from a command line environment,if you want to use them as external tools in an already established project environment. 官方的介绍文档主要就是《 IAR C/C++ Development Guide...
cmake ../llvm-5.0.0.src -DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_BUILD_TYPE=Release -DLLVM_USE_LINKER=gold # 执行完上面的命令后, 此时llvm里面有三个文件夹, 此时在build文件夹内 # llvm-5.0.0.src/ # libcxx-5* # build # 如果上面报错 ...
--> linker:::流程 --> a.out 因为main.bc是二进制版本的bitcode,可读性比较差。 开发者可以通过llvm-dis main.bc -o -命令转为更具有可读性的版本: ; ModuleID ='main.bc' source_filename ="~/main.m" target datalayout ="e-m:o-p270:32:32-p271:32:32-p272:64:64-i64:64-f80:128-...
C-like languages use theClangfrontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM. Other components include: thelibc++ C++ standard library, theLLD linker, and more. ...
