We were using uint64 function arguments as "long int" arguments to compiler builtins, which fails on machines where long ints are 32 bits: the upper half of the uint64 was being ignored. Fix by using the "ll" builtin variants instead, which on those machines take 64 bit arguments. Also, remove configure tests for __builtin_popcountl() (as well as "long" variants for ctz and clz): the theory here is that any compiler version will provide all widths or none, so one test suffices. Were this theory to be wrong, we'd have to add tests for __builtin_popcountll() and friends, which would be tedious. Per failures in buildfarm member lapwing and ensuing discussion. |
