Porting the GNAT Ada compiler to macOS/aarch64 (briancallahan.net)
After getting a port of GDC working on my new MacBook Pro, there are still two languages left in the GCC suite that I don't have: Ada and Go.

Finding Missed Code Size Optimizations in Compilers Using LLMs (arxiv.org)
Compilers are complex, and significant effort has been expended on testing them. Techniques such as random program generation and differential testing have proved highly effective and have uncovered thousands of bugs in production compilers. The majority of effort has been expended on validating that a compiler produces correct code for a given input, while less attention has been paid to ensuring that the compiler produces performant code.

Lightstorm: Minimalistic Ruby Compiler (llvm.org)
Some time ago I was talking about an ahead-of-time Ruby compiler. We started the project with certain goals and hypotheses in mind, and while the original compiler is at nearly 90% completion, there are still those other 90% that needs to be done.

Into CPS, Never to Return (bernsteinbear.com)
CPS, or continuation-passing style, is an intermediate representation for programs, particularly functional programs. It’s used in compilers for languages such as SML and Scheme.

Rust’s Incremental Compiler Architecture (lwn.net)
The traditional structure of a compiler forms a pipeline — parsing, type-checking, optimization, and code-generation, usually in that order. But modern programming languages have requirements that are ill-suited to such a design. Increasingly, compilers are moving toward other designs in order to support incremental compilation and low-latency responses for uses like integration into IDEs.

Common misconceptions about compilers (sbaziotis.com)
Compilers have always been surrounded by an air of mystery and magic. This has led many of us to believe that they do things (well) that they don't, or that they don't do things (well) that they do.

Everything You Never Wanted to Know About Linker Script (2021) (mcyoung.xyz)
The linker script, provided to Clang as -Wl,-T,foo.ld1, is like a template for the final executable. It tells the linker how to organize code from the input objects. This permits extremely precise control over the toolchain’s output.

C Compiler to SPIR-V (github.com/heroseh)
HCC is a C compiler that allows you to compile your C codebase (with limitations) to SPIR-V for the Vulkan graphics API. This means you can share struct's, enum's and functions between your CPU & GPU code. HCC targets the future of GPU programming so is designed around features such as bindless resources and scalar alignment. This makes it easier to interop with the GPU and focus on writing shader code without writing your own shader build system.

Gccrs: An Alternative Compiler for Rust (rust-lang.org)
gccrs is a work-in-progress alternative compiler for Rust being developed as part of the GCC project. GCC is a collection of compilers for various programming languages that all share a common compilation framework. You may have heard about gccgo, gfortran, or g++, which are all binaries within that project, the GNU Compiler Collection. The aim of gccrs is to add support for the Rust programming language to that collection, with the goal of having the exact same behavior as rustc.
