FrontEnd is a translation pass from source to the AST IntermediateLanguage.

Description

Details and Notes

The lexer is produced by MLLex from ml.lex .

The parser is produced by MLYacc from ml.grm .

The specifications for the lexer and parser were originally taken from SML/NJ (version 109.32), but have been heavily modified since then.
