The most important win of this classical design comes when a compiler decides to support multiple source languages or target architectures. If the compiler uses a common code representation in its optimizer, then a front end can be written for any language that can compile to it, and a back ...
“In a project with N translation units and M headers included in each translation unit, the compiler is performing M x N work even though most of the M headers are shared among multiple translation units. ” 也就是 Module 设计的目的是为了解决头文件重复引用的问题,使 M x N 复杂度的问题降...

其中,Arm Compiler 6 被 ARM 称为是 Arm Compiler 5 的替代者!相比于 Arm Compiler 5 的使用的 Edison Design Group 编译器前端,Arm Compiler 6 将编译器前端换为了基于 LLVM 的 Clang! 在ARM 官网的介绍中,有如下一段话 General update releases on the last branch, version 5.06, ended in H2...
This design also implies that it is possible to design and implement radically different code generators in the LLVM system that do not make use of any of the built-in components. Doing so is not recommended at all, but could be required for radically different targets that do not fit into...
We describe the design of the LLVM representation and compiler framework, and evaluate the design in three ways: (a) the size and effectiveness of the representation, including the type information it provides; (b) compiler performance for several interprocedural problems; and (c) illustrative ...
) 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 to invent your own language (or port an existing compiler) to use LLVM as an optimizer ...
引言:LLVM(Low Level Virtual Machine)作为现代编译器基础设施的标杆,每一次版本更新都牵动着开发者的心。近日,LLVM 官方发布了lvmorg-20.1.3版本,带来了一系列性能优化、Bug 修复和新特性支持。本文将带你深入解析这一版本的亮点,助你掌握最新编译技术动态!
In this thesis, we attach the LLVM JIT compiler into JNA to get better performance based on the study of Java Native Interface. The experiment results indicate about 7.84% performance improvement for calling a native function with only one argument. Our design is a non-traditional way of using...
1. A Quick Introduction to Classical Compiler Design 传统编译器使用3-phase设计,即将编译器区分为front end, optimizer和backend三部分。 front end: 解析源代码,检查基本错误,建立AST(有时还会为了优化进一步转为IR) optimizer: 一系列优化(这些优化相对语言本身或者平台本身稍微独立),通常包括避免冗余计算。
