* | add a_clz_64 helper function | Szabolcs Nagy | 2017-08-29 | 1 | -0/+7 |
| | | | | | | | | | counts leading zero bits of a 64bit int, undefined on zero input. (has nothing to do with atomics, added to atomic.h so target specific helper functions are together.) there is a logarithmic generic implementation and another in terms of a 32bit a_clz_32 on targets where that's available. | ||||
