Dale Weiler	a934e0fe4b	Happy new year!	2014-01-01 06:24:16 -05:00
Wolfgang Bumiller	b1016c7f48	fold_binary now used instead of ast_binary_new, which calls fold_superfluous	2013-10-25 13:40:31 +02:00
Dale Weiler	8699053887	Fix handling on intrinsic folding, this closes #118.	2013-10-17 00:14:42 -04:00
Dale Weiler	50d165e173	Some intrinsic code cleanup. The args check is handled anyways in the parser. We use a generated array alongside to prevent generating the intrinsic multiple times instead of using static storage. Other various cleanups as well.	2013-10-16 00:04:39 -04:00
Dale Weiler	cc69370575	Another peephole optimization which removes superfluous expressions such as (A + 0), (A - 0), (A * 1) and (A / 1).	2013-10-04 06:46:54 -04:00
Dale Weiler	15b0555546	Implement constant folding on ternary operations via fold_cond.	2013-09-26 06:51:49 -04:00
Dale Weiler	a50635bcd7	intrinsic folding cleanups (and improvements.)	2013-08-30 07:12:16 -04:00
Dale Weiler	3b4a5667ea	Constant fold intrinsics if their arguments are constant. TODO: reference count intrinsics such that they're not generated unless they're used, currently when an intrinsic can be folded-away it's marked for generation and makes it to the final output binary even though it isn't used.	2013-08-28 12:46:22 -04:00
Dale Weiler	73d9aa29c4	Made intrinsics seperate from the parser.	2013-08-14 06:02:15 +00:00
Dale Weiler	10b75fd8b9	Move const-branch-elision into fold.c	2013-07-31 19:34:38 +00:00
Dale Weiler	d0ee56f25f	more fixes	2013-07-31 16:31:45 +00:00
Dale Weiler	920dbaf1e0	Work in progress constant-folding rewrite.	2013-07-31 09:04:19 +00:00
