我们为大家带来了一个新的专题,即《从零开始学习LLVM》,主要是翻译巴西米纳斯吉拉斯州联邦大学 (UFMG)DCC888 课程中对 LLVM 的介绍。这个课程的每节课都比较简短,对应的视频也基本在10分钟以下,相信大家学习起来会非常轻松。希望对这个视频专题可以帮助到想学习和了解
LLVMUpdated: 08/16/2024 by Computer HopeLLVM is a compiler infrastructure used to optimize code for different programming languages. It provides re-usable "toolchain technologies" to process the intermediate form of a program during the compilation process. This utility allows LLVM to analyzing a ...
The LLVM project/infrastructure: This is an umbrella for several projects that, together, form a complete compiler: frontends, backends, optimizers, assemblers, linkers, libc++, compiler-rt, and a JIT engine. The word "LLVM" has this meaning, for example, in the following sentence: "LLVM is...
LLVM is a compiler framework for programmatically generating machine-native code. Developers use it to roll out new languages and enhance existing ones.
Here is a simple example: llvm::LLVMContext &Ctx = LLMod.getContext(); llvm::IntegerType *Int32Ty = llvm::Type::getInt32Ty(Ctx); llvm::Metadata *MapleVerElts[] = { llvm::ConstantAsMetadata::get(llvm::ConstantInt::get(Int32Ty, 0)), llvm::ConstantAsMetadata::get(llvm::ConstantInt...
Scripting languages, like Perl and PHP (PHP: Hypertext Preprocessor), do not need to be compiled and use an interpreter to run.What is compile time?The compile time is the total time it takes a compiler to compile code into a program that can be run by the computer.Related...
When we still had standalone builds it was easy to point your finger at an LLVM sub-project that broke a build. We would assign a label such as project/llvm or project/clang. At the moment we only assign project/llvm all the time. It wou...
@code_llvm shows the optimised LLVM @code_native shows the native assembly of the function From here, you can repeatedly modify and run the function, and immediately see the resulting impact on inference and codegen. This means even micro-optimising Julia code is laughably easy.Julia...

So my question is: why do we need `${p}` for the first ins argument, and what are the first and second operands of MI? Can we just remove all of {p} there and sort the operand order as normal instructions? Here is the reference: https://developer.arm.com/documentation/ddi0553/lat...
