With the historical background and context out of the way, let's dive into LLVM: The most important aspect of its design is the LLVM Intermediate Representation (IR), which is the form it uses to represent code in the compiler. 最重要的部分是 LLVM IR,编译器用它来作代码表示。 LLVM IR...
LLVM is an infrastructure, a collection of useful compiler technology that can be brought to bear on specific problems (like building a C compiler, or an optimizer in a special effects pipeline).[1] 自由化的定制能力 让我们来看一个优化器的例子: 读进来LLVM IR emit更优的LLVM IR. 在LLVM中,...
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 ...

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...
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...
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...
) 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 ...
Fig. 3 Number of spins in IC Designs 由于设计的复杂性和生产效率之间的差距越拉越大,必须有一种全新的设计方 法来简化设计的复杂性,减少重新流片的次数,降低 NRE 成本,让电子系统设计 回到一个合理的范围,这些要求触发了基于平台设计的出现。Vincentelli 在“Defining platform-based design”一文中对基于平台的...
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!
