Slava Pestov	910748819d	Now that #foo and ##foo are symbols we can remove a bunch of \	2011-11-12 22:04:26 -08:00
Joe Groff	41c36752fc	compiler.cfg.tco: clean up commented-out old code	2011-10-27 21:14:47 -07:00
Joe Groff	6f75e84d93	compiler.cfg.tco: teach TCO about safepoints	2011-10-27 21:14:46 -07:00
Joe Groff	191ac353fd	generalize stack effects so we can bootstrap with the stricter stack effect checking	2010-03-08 23:38:10 -08:00
Slava Pestov	d0c393aa60	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
Slava Pestov	725280d424	Split off the notion of a register representation from a register class	2009-08-07 17:44:50 -05:00
Slava Pestov	e76dce8aff	Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint	2009-07-16 18:29:40 -05:00
Slava Pestov	9f926ab88c	compiler.cfg.block-joining: join basic blocks connected by a single edge to improve effectiveness of local optimizations	2009-07-16 02:17:58 -05:00
Slava Pestov	608fb054f2	compiler.cfg: Some code cleanups, update stack-analysis and phi-insertion to work on CFGs with critical edges	2009-07-12 22:22:46 -05:00
Slava Pestov	f412bbc6d6	Change branch splitting around a bit, rename useless-blocks to useless-conditionals and rewrite it	2009-06-30 22:11:15 -05:00
Slava Pestov	3da560130a	compiler.cfg.tco: fix tail call optimization for ##fixnum-mul	2009-06-30 21:08:08 -05:00
Slava Pestov	5c6c3ecd85	compiler.cfg.tco: Tail call optimization moved out of compiler.cfg.builder into its own pass	2009-06-30 20:13:35 -05:00
