* Basic grammar and parser for the Fix language. We use libsglr and friends to do the parsing. The parse table is embedded in the Fix executable using bin2c, which converts an arbitrary file into a C character array. 2003-10-29 16:05:03 +00:00

* Replaced the SDF parser by a substantially faster Bison/Flex parser (roughly 80x faster). The absolutely latest version of Bison (1.875c) is required for reentrant GLR support, as well as a recent version of Flex (say, 2.5.31). Note that most Unix distributions ship with the prehistoric Flex 2.5.4, which doesn't support reentrancy. 2004-01-30 15:21:42 +00:00			`# Parser generation.`
