LLVM is a compiler framework for programmatically generating machine-native code. Developers use it to roll out new languages and enhance existing ones. Credit: Matejmo / Getty Images The development landscape is ripe with new languages and improvements on existing ones. Mozilla’s Rust, Apple...
In this email, I argue that LLVM IR is a poor system for building a Platform, by which I mean any system where LLVM IR would be a format in which programs are stored or transmitted for subsequent use on multiple underlying architectures. LLVM IR initially seems like it would work well he...
The LLVM compiler infrastructure project lives at the heart of the Clang C/C++ compiler, and the compilers for languages like Rust and Zig. This video shows in detail the concepts behind LLVM, such as how code in one language is translated into LLVM's own internal language. In this series...
The LLVM Compiler Infrastructure Welcome to the LLVM project! This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments. The LLVM project has multiple components. The core of the project is itself called "...
It allows the value of an LLVM register to be set to one of a group of values, depending on the basic block from which the current value was entered. Consider the following snippet of C: if(condition) a = 1; else a = 2; In LLVM, or any other compiler with an SSA intermediate ...

llvm构建时,会产生“attribute 'visibility' is ignored, place it after "struct" to apply attribute to type declaration”报错。经检查,是由于先#defineEXPORTattribute((visibility("default"))),而在实际使用中,写成例如__EXPORT__ struct lcr_start_request{...};,违背了__attribute__语法规则,__attribute...
LLVM is more than just a compiler backend (code generator) these days. It has become the umbrella project for many other of the toolchains from other language front-ends, to linkers, and debuggers, and many other ancillary build tools. For instance, one of the other tools we’ve been inv...
llvm-bolt 介绍 BOLT is a post-link optimizer developed to speed up large applications. It achieves the improvements by optimizing application's code layout based on execution profile gathered by sampling profiler, such as Linux perf tool.
我们需要根据这个补丁修改源码:Fix sanitizer build against latest glibc · llvm-mirror/compiler-rt@8a5e425 · GitHub 但别急,不用改这么多,只需要改报错的这个文件(.../libsanitizer/tsan/tsan_platform_linux.cc),把其中的: __res_state *statp = (__res_state*)state; 改成 struct __res_state...
