LLVM Code Generation - A deep dive into compiler backend development

Quentin Colombet

Summary

The LLVM infrastructure is a popular compiler ecosystem widely used in the tech industry and academia. This technology is crucial for both experienced and aspiring compiler developers looking to make an impact in the field. Written by Quentin Colombet, a veteran LLVM contributor and architect of the GlobalISel framework, this book provides a primer on the main aspects of LLVM, with an emphasis on its backend infrastructure; that is, everything needed to transform the intermediate representation (IR) produced by frontends like Clang into assembly code and object files.You’ll learn how to write an optimizing code generator for a toy backend in LLVM. The chapters will guide you step by step through building this backend while exploring key concepts, such as the ABI, cost model, and register allocation. You’ll also find out how to express these concepts using LLVM's existing infrastructure and how established backends address these challenges. Furthermore, the book features code snippets that demonstrate the actual APIs.By the end of this book, you’ll have gained a deeper understanding of LLVM. The concepts presented are expected to remain stable across different LLVM versions, making this book a reliable quick reference guide for understanding LLVM.

Housing and Urban Policy -...

Lyric Vale

Housing and urban policy play a crucial role in shaping the development and functioning of cities. These policies not only determine how housing is distributed, financed, and regulated but also have a profound impact on the quality of life for urban residents. As urban populations grow at unprecedented rates, particularly in developing regions, the need for comprehensive housing policies that address affordability, accessibility, and sustainability becomes increasingly urgent.
At its core, housing policy refers to the set of laws, regulations, and strategies designed to ensure that all residents have access to safe, affordable, and adequate housing. Urban policy, meanwhile, extends beyond housing to include broader strategies for city planning, infrastructure, and public services. Together, housing and urban policy aim to create cities that are not only livable but also resilient, inclusive, and sustainable.
Historically, housing policies have evolved in response to changing economic, social, and political circumstances. From post-war housing booms to modern challenges like urban sprawl and rising inequality, policies have adapted in varying ways. However, many cities still struggle with issues like the shortage of affordable housing, homelessness, and housing inequality. Rapid urbanization, exacerbated by global migration and population growth, has put further strain on already limited housing resources. As a result, addressing housing needs has become one of the foremost concerns for urban policymakers around the world.

The Internet

Owen Jones

I hope that you will find the information helpful, useful and profitable. 
The ideas in this ebook on various aspects of the Internet including using it to your advantage is organised into 17 chapters of about 500-600 words each. 
I hope that it will interest those who are hoping to make money on line, and those who want to attract more traffic to an offline business by using the often ‘free’ resources that the Internet has to offer. It will also be useful to bloggers who just want to make friends all over the world and chat with them. Luckily, many aspects of the Internet are still free, especially if you don’t allow yourself to be manipulated by the self-proclaimed Internet gurus, who are waiting to pounce on unsuspecting newbies. 
As an added bonus, I am granting you permission to use the content on your own website or in your own blogs and newsletter, although it is better if you rewrite them in your own words first.
