1612515 - Land rust-frontend changes behind a configure flag

Status: RESOLVED FIXED

(Core :: JavaScript Engine, enhancement, P1)

Description

[Jason Orendorff [:jorendorff]]

The rust-frontend repository is a crude hack to get the new frontend bootstrapped, but I'd like to land those changes (without too much cleanup) behind a flag so that our team can work in mozilla-central. The rust-frontend repo will be retired.

For now, when you build with this flag, you'll have to specify the directory containing jsparagus, which contains the parser generator and many hand-coded Rust bits: the lexer, AST, AST builder, and emitter.

Making the user provide a jsparagus directory means we don't have to constantly land snapshots of it in mozilla-central. Later we'll have to do that.
