@@ -215,3 +215,15 @@ talloc_parent() call is expensive, so many passes will cache the
result of the first talloc_parent(). Cleaning up all the optimization
passes to take a context argument and not call talloc_parent() is left
as an exercise.

+Q: What is the file naming convention in this directory?
+
+Initially, there really wasn't one. We have since adopted one:
+
+ - Files that implement code lowering passes should be named lower_*
+ (e.g., lower_noise.cpp).
+ - Files that implement optimization passes should be named opt_*.
+ - Files that implement a class that is used throught the code should
+ take the name of that class (e.g., ir_hierarchical_visitor.cpp).
+ - Files that contain code not fitting in one of the previous
+ categories should have a sensible name (e.g., glsl_parser.ypp).
