How can I learn LLVM?

Here are some more LLVM related channels I recommend looking at:

1. LLVM’s YouTube channel. Here you can find a lot of talks from developer meetings.
2. LLVM Weekly. A weekly newsletter run by Alex Bradbury.
3. LLVM Blog. This is, well, LLVM’s blog.
4. LLVM Tutorials.
5. Embedded in academia.

What is LLVM frontend?

LLVM is a set of compiler and toolchain technologies, which can be used to develop a front end for any programming language and a back end for any instruction set architecture. LLVM is written in C++ and is designed for compile-time, link-time, run-time, and “idle-time” optimization.

How do I write my pass in LLVM?

Start out with:

1. #include “llvm/Pass.h” #include “llvm/IR/Function.h” #include “llvm/Support/raw_ostream.h”
2. using namespace llvm;
3. namespace {
4. struct Hello : public FunctionPass {
5. static char ID; Hello() : FunctionPass(ID) {}
6. bool runOnFunction(Function &F) override { errs() << “Hello: “; errs().
7. char Hello::ID = 0;

What is the purpose of LLVM?

LLVM helps build new computer languages and improve existing languages. It automates many of the difficult and unpleasant tasks involved in language creation, such as porting the outputted code to multiple platforms and architectures.

What is LLC in LLVM?

DESCRIPTION. The llc command compiles LLVM source inputs into assembly language for a specified architecture. The assembly language output can then be passed through a native assembler and linker to generate a native executable.

What is a pass Manager LLVM?

What is a pass manager? A pass manager schedules transformation passes and analyses to be run on IR in a specific order. Passes can run on an entire module, a single function, or something more abstract such as a strongly connected component (SCC) in a call graph or a loop inside of a function.

What is the role of frontend components in LLVM?

The frontend components are responsible for translating the source code into the Intermediate Representation (IR) which is the heart of the LLVM infrastructure.

What is the LLVM backend?

The LLVM backend takes in input a valid IR code and generates the optimized machine code simplifying the compiler implementation. The LLVM project is released under the Apache License v2.0 (with some exceptions) which allows to include the software as part of commercial products.

What is llllvm?

LLVM is a Compiler Infrastructure ❖Set of libraries for building compiler tools ❖Write tools to analyze software behavior ❖Write tools that control program behavior 8 Ahead of Time (AOT) Compiler Front End Optimizer Code Generator 9 Clang AST LLVM IR LLVM Machine IR Parsed Source Code Tree

What are the major building blocks of LLVM?

The major building blocks of LLVM can be subdivided in three logical categories: the frontend, the intermediate representation (IR) and the backend. The frontend components are responsible for translating the source code into the Intermediate Representation (IR) which is the heart of the LLVM infrastructure.
