The hottest Compiler Substack posts right now

Groq's LPU showcases an innovative design departing from traditional architectures, focusing on deterministic execution for enhanced performance.
The TSP architecture achieves determinism through a simplified hardware design, enabling precise scheduling by compilers for predictable performance.
Groq's approach to creating a distributed multi-TSP system eliminates non-determinism typical in networked systems, with the compiler efficiently managing data movement.

Booleans in Swift are very basic - just true or false.
Behind the scenes, Swift Booleans are actually structs with a 1-bit integer property.
Swift uses protocols like ExpressibleByBooleanLiteral for instantiating Boolean values.

Extending LLVM to support new RISC-V instructions involves modifying source files and declarations in LLVM's target description files
Testing the generated binary involves building LLVM with RISC-V support, enabling experimental extensions, and linking the binary with the GNU toolchain
This process allows programmers to utilize new RISC-V extensions and instructions efficiently

isKnownUniquelyReferenced checks if strong reference count is 1
Swift components like Builtin, AST, SIL, LLVM work together for this optimization
Understanding memory management internals can help in optimizing code

When creating a new programming language, start by making examples to define how it will look and function.
Select a language for your compiler that you are comfortable with, and consider libraries to simplify parsing and generating output.
Include key components like a tokenizer, parser, and generator in your compiler, and focus on type checking and editor tooling for a better user experience.
