| 07:21 | More verbose names (str() -> get_string(), ...) and make it easier to change symbol table size (in case the code's ever used elsewhere). check-in: e7e04f5335 user: martin tags: trunk | |

| 22:57 | gcc->clang; c89->c99; Change how tail calls are handled; Lose fexp/macro until I get around to seeing why they cared (and, probably, macro's just permanently gone); symtable now uses FNV hash rather than simple additive; clean up a bunch of warnings from clang's -Weverything (mostly making casts explicit); precomp_lookups just inlines the fn rather than its binding (again). check-in: fa28c9b5d7 user: martin tags: trunk | |
