--- Comment #5 from Yi He <yi...@linaro.org> --- Hi, Petri Since the algorithm is: 1 << total bits - leading zero bits(x - 1) __builtin_clz's parameter is (unsigned int), so the total bit number need to be calculated as 4 * sizeof(unsigned int) otherwise input an unsigned long will result incorrect calculation, for example: unsigned long i = 1024: 1 << (8 * sizeof(i) - __builtin_clz(1024 - 1)) -> result: 1 << 42, too big. for unsigned long, __builtin_clzl need to be used. -- You are receiving this mail because: You are on the CC list for the bug.
