Slava Pestov d2d466de29 Language change: tuple slot setter words with stack effect ( value object -- ) are now named FOO<< instead of (>>FOO) 2010-05-06 17:21:02 -04:00
Slava Pestov 88d15dfbea compiler.cfg: new system to track when results of analyses need to be recomputed (reverse post order, linear order, predecessors, dominance, loops). Passes can now call needs-predecessors, needs-dominance, needs-loops at the beginning, and cfg-changed, predecessors-changd at the end. Linearization order now takes loop nesting into account, and linear scan now uses linearization order instead of RPO. 2009-08-08 20:02:56 -05:00
