655c2482c9 Fix vec3_cross. Added optimization to Makefile since we've been compiling gmqcc without it since forever. 2014-05-25 02:04:10 -04:00

05e20bcdda Some things. Fix testsuite as well. One test will fail (inexact). 2014-05-24 11:42:10 -04:00

bbeb2517c0 Arithmetic exception flag and a plethora of tests. 2014-05-24 10:38:02 -04:00

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

6d8d7ee923 Make divVerent happy about handling divison by zero/inf/nan and negitive versions. This code now assumes IEEE 754. 2013-10-14 22:31:37 -04:00

69252071ba Prevent divide by zero for / and % operations in constant folding (previously caused compiler SIGFPE), instead "inf" is generated for both cases. This closes #124 2013-08-31 12:57:24 -04:00

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
