Edward Thomson	16942c6fda	integer overflow: use compiler intrinsics if supported ... gcc and clang support __builtin_add_overflow, use it whenever possible, falling back to our naive routines.	2015-02-13 09:28:09 -05:00
Edward Thomson	f1453c59b2	Make our overflow check look more like gcc/clang's ... Make our overflow checking look more like gcc and clang's, so that we can substitute it out with the compiler instrinsics on platforms that support it. This means dropping the ability to pass `NULL` as an out parameter. As a result, the macros also get updated to reflect this as well.	2015-02-13 09:27:33 -05:00
