Dale Weiler	a50635bcd7	intrinsic folding cleanups (and improvements.)	2013-08-30 07:12:16 -04:00
Dale Weiler	51ef277e21	Fix folding logic for conditions.	2013-08-29 00:18:48 -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	ee428b9081	Fix fold-dce for if(0)	2013-08-28 10:39:48 -04:00

Dale Weiler	91c7209146	Track constant folds in opts_optimization list .. this could be handled better I assume.	2013-08-15 03:45:50 +00:00

Dale Weiler	7669a99c7f	increment the optimization counter for DCE'd folds, also enable -O3 for compilation.	2013-08-01 14:24:10 +00:00
Dale Weiler	db69d14995	Disable the macros to keep clang happy (just uncomment them for when more constant folding optimizations need them)	2013-08-01 07:12:21 +00:00
Dale Weiler	6f749d61b1	Added -Oconst-fold-dce (dead code elimination optimization for when constant expressions form the basis of the dead code, i.e if else with constant expression). Fixed deps and added documentation. Cleaned up folds for ir_value (can now use the same macros as the ast_value ones).	2013-08-01 07:07:59 +00:00

Dale Weiler	fa5ad1212e	Operator constant folding rewrite almost complete, just need to track down why two tests are failing.	2013-07-31 15:49:45 +00:00
Dale Weiler	86adb94d7d	folding for lteqgt (less than equal to or greater than) operator a.k.a <=> which maps values to -1,0,1 depending on the result (think of the result as a troolan) .. it's a perl thing :P	2013-07-31 12:59:34 +00:00
