I wrote a linker everyone can understand
When we wrote our assembler we made many design choices that helped us cut down on the complexity of the assembler itself. One of those decisions was to have the assembler directly output executables. That was a good choice in that it allowed us to quickly test as we were developing: once we implemented an opcode, we…

Engineering a Chess Match
This is the story of me trying to win a game of chess against my brother. A single freaking game. What’s so special about it? Am I good at chess? Not at all. Did I improve at my game in the process? Also no. Is it a story about “the journey rather than the destination”? Not really. Did I at least have fun in the…

Design Issues in LLVM IR
On the whole, LLVM has a well-designed intermediate representation (IR), which is specified in the language reference . However, there are a number of areas where design mistakes have been made. And while the LLVM project is generally open to addressing such issues, mistakes in core IR design tend to be firmly…

Abstract Syntax Tree for Patching Code and Assessing Code Quality
Abstract Syntax Tree is an extremely useful tool. It provides a tree representation of a source code, that can be traversed to parse the code while understanding the code’s language constructs. In this article, we explain how we have used ASTs to write IntelliPatch scripts that can...

Clever vs. Insightful Code
“Don’t write clever code.” Why not? “Because it’s hard to understand.” People who say this think of clever code such as Duff’s Device: Duff's Device send(to, from, count) registershort*to, *from; registercount; { registern =(count +7) /8; switch(count %8) { case0: do{ *to =*from++; case7: *to =*from++; case6: *to…

Conway's Game of Life on FPGA
When learning a new programming language, I like having a well defined yet non-trivial problem to solve. Conway’s Game of Life (GoL) fits this definition. It has enough depth to uncover various tradeoffs. So naturally, when I picked up Chisel hardware description language (HDL), I wanted to build Game of Life in FPGA…

Implementing a LLVM Micro C compiler in Haskell
In this series, we will explore how to write a compiler for a small subset of C to LLVM in Haskell. Our language, Micro C, is basically a small subset of real C. We'll have basic numeric types, a real bool type, pointers, and structs. At the end of the series, we'll have a beautiful executable, mcc (Micro C…
