Björn Lindqvist	9ceea3c241	compiler.*: new cfg instruction ##clear, it makes it easier to see where the compiler.cfg.stacks.clearing pass inserts extra instructions	2015-05-17 07:59:34 +02:00
Björn Lindqvist	6dd2fe31b6	compiler.cfg.stacks.*: new attempt at fixing the gc maps bugs the padding vocab is inverted so that instead of trying to track which locations are live, it tracks those which are dead which is much easier to get right.	2015-05-17 07:59:34 +02:00
Björn Lindqvist	ecf3829843	compiler.cfg.stacks.*: new vocab 'padding' to perform much more accurate live analysis. it will replace the 'map' vocab	2015-05-09 20:04:22 -07:00
Björn Lindqvist	a195e361df	compiler.cfg.stacks.*: create-locs, word for creating stack locations from a sequence	2015-05-09 20:04:21 -07:00
Björn Lindqvist	71b054cf39	compiler.cfg.stacks.*: updated tests to match	2015-01-22 12:17:21 -08:00
Björn Lindqvist	d4493858da	compiler.cfg.stacks.*: vacant-peek checking readded	2015-01-22 12:17:20 -08:00
Björn Lindqvist	640759ffed	compiler.cfg.*: new step in finalization: clear-uninitialized this step is supposed to analyze the cfg, find where there are peeks that can cause stack underflow, and insert replace-imm instructions so that there are no uninitialized stack locations if they do. could fix #1187	2015-01-22 12:17:20 -08:00
