Jeff Hostetler c92987d1 2015-02-20T10:21:32 Fix MAX 32 bit build problem described in libgit2/libgit2#2917
Edward Thomson 16942c6f 2015-02-12T17:36:48 integer overflow: use compiler intrinsics if supported gcc and clang support __builtin_add_overflow, use it whenever possible, falling back to our naive routines.
Edward Thomson f1453c59 2015-02-12T12:19:37 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.
Edward Thomson 190b76a6 2015-02-11T14:52:08 Introduce git__add_sizet_overflow and friends Add some helper functions to check for overflow in a type-specific manner.
