Squash is a patch generation tool to assist with Gecko:DeCOMtamination. This blog post describes how to use squash.

Squash: refactoring tool

Quickly produce large refactoring patches
Automate parts of deCOMtamination: class squashing & out-param rewriting (in the near future)
Helps replace deprecated APIs at call-sites & function renaming
Could be integrated into any editor to do eclipse-style refactoring.
Has a web frontend.
Since the squash isn't tied to an IDE, it should evolve quicker. If you discover a boring rewrite task that could be implement as an algorithm - it maybe easier to extend squash than to perform it by hand.
FIXME: CPP causes blind-spots in the code.
FIXME: Lack of precise source locations in parts of the AST.

TODO: Add Objective C++ support for OSX issues like Exception Checking

-* Match on control flow<br>eg can find mismatched malloc/free calls
-* Inspired by UNO, but supports nested AST structures and types allowing more precise pattern matching
-* Uses JS instead of a custom DSL
-* Cross-function analyses being worked on
-** Can build a complete call graph, with custom hooks for callbacks, etc
-** Should be able to find unused functions
-** Prove that functions are only used in certain ways
-Making Attractive Tools
-*Accidental byproduct of using JS in dehydra is that analyses can easily be serialized into a form consumable by AJAX applications
-** This opens up exciting ways to visualize Mozilla code in ways that IDEs don't allow.
-** Pump Eclipse-style navigation abilities into LXR
-**  Use Firefox with SVG, Canvas, (OpenGL?) to develop Firefox
-** JS is a perfect tool for Graydon's old idea of producing a consumable "AST" blob of Mozilla that one can run own scripts on to research code properties
-* Squash could be integrated into any editor to do eclipse*style refactoring (Not sure if it's worth the hassle)
-* Making smart & generic C/C++ tools is hard, but making generic tools that focus on Moz2 is doable
-* Since the tools aren't tied to an IDE they should evolve quicker, so if you discover a boring task that could be implement as an algorithm - it may not be as hard to implement as it seems.
