Slava Pestov a56d480aa6 Various optimizations leading to a 10% speedup on compiling empty EBNF parser: ... - open-code getenv primitive - inline tuple predicates in finalization - faster partial dispatch - faster built-in type predicates - faster tuple predicates - faster lo-tag dispatch - compile V{ } clone and H{ } clone more efficiently - add fixnum fast-path to =; avoid indirect branch if two fixnums not eq - faster >alist on hashtables		2008-12-06 09:16:29 -06:00

def-use	Tweak string representation; high bit indicates if character has high bits in aux vector. Avoids memory access in common case. Split set-string-nth into two primitives; set-string-nth-fast is open-coded by optimizing compiler. 13% improvement on reverse-complement	2008-12-05 06:38:51 -06:00
