module Savi::Compiler::Classify

Overview

The purpose of the Classify pass is to do some further semantic parsing of AST forms to add additional context about what those forms mean, in the form of flag bits being set on the state of the AST nodes themselves.

This pass does not mutate the Program topology. This pass sets flags on AST nodes but does not otherwise mutate ASTs. This pass does not raise any compilation errors. This pass keeps temporary state (on the stack) at the per-function level. This pass produces no output state.
