Dale Weiler	b5ac2745d6	Remove license headers. The LICENSE file is sufficent	2015-01-13 21:38:40 -05:00

Dale Weiler	6424ebaf98	Perliminary work on arithmetic exception handling in the constant evaluator. We can safely check for arithmetic underflow, overflow, divison by zero and inexactness now. Inexactness of expressions are propagated through the AST such that using an inexact value in a comparison will trigger a warning with -Winexact-compares.	2014-05-24 09:53:38 -04:00
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
