ZNode - A Javascript Introspection module
ZNode is a minimalistic browser based flowchart module. I took this project and modified it heavily so that it could do some basic javascript introspection and show them as blocks. Think of it like...
Designing a Regular expression engine in python
Regular expressions or regex are pretty popular for text searching and replacing. They are widely used and in this post I will basically link my implementation in python.
Adapting Luajit for Python 3
I have looked at spidermonkey and a few other JIT engines and kept on reading about LuaJit over and over again. I finally decided to look at Luajit closely and realized that it is a pretty complex ...
Incremental text search using tries and ternary trees
While brushing up on algorithms, I decided to reimplement tries and ternary trees and in the process thought it would be a good idea to write a UI accompanying the code so its easier to see. Could ...
Loopy - A Structurizer for generating structured control flow code.
A structurizer is used when the IR is unstructured but the code to be generated needs to be structured. A structured control flow represents idioms which are generally present in higher-level langu...
Dominator Trees - Implementation and Why are they needed?
A Dominator Tree is a CFG analysis which is used in compilers to aid in other optimizations. This is useful when doing optimizations like code-hoisting or code sinking etc.
Constant Propagation & Folding.
Constant propagation and folding are generic optimizations which can greatly simplify the intermediate representation. It is the basis for other optimizations like loop unrolling, loop simplificati...
