e707eeb7c8 THis includes fix for special case when conversion from fp to int/long. The previous src did not test both the flags and result and so missed this subtle bug when an Invalid happens for this type of conversion. These results are indications of undefined behavior for these operations. All fp operations now passs when this update is fixed. Much of the information why these outputs should occur is somewhat alluded to by Pascal Cuoq originally from INSA in Lyon here: https://frama-c.com/2013/10/09/Overflow-float-integer.html 2024-01-12 00:37:50 -06:00
