Jasmine: Convert |reportMissingRules| compiler pass tests
13 years ago
describe("compiler pass |reportMissingRules|", function() {
Plugin API: Split compiler passes into stages The compiler passes are now split into three stages: * check -- passes that check for various error conditions * transform -- passes that transform the AST (e.g. to perform optimizations) * generate -- passes that are related to code generation Splitting the passes into stages is important for plugins. For example, if a plugin wants to add a new optimization pass, it can add it at the end of the "transform" stage without any knowledge about other passes it contains. Similarly, if it wants to generate something else than the default code generator does from the AST, it can just replace all passes in the "generate" stage by its own one(s). More generally, the stages make it possible to write plugins that do not depend on names and actions of specific passes (which I consider internal and subject of change), just on the definition of stages (which I consider a public API with to which semver rules apply). Implements part of GH-106.

Specs cleanup: Simplify compiler passes specs After 898a7b5a2d0438aecfca9d0ec548ff60fcb00747 the specs mostly tested the visitor implementation, not actual code in the passes.
