This simplifies and cleans up the code. Furthermore, it is much faster due to absence of the slow log computation. Reviewed-by:

ISO C restricts enumerator values to the range of int. Thus (for instance) 0x80000000 unfortunately does not work, and throws a warning with -Wpedantic on clang 3.7. This fixes it by using alternative expressions that result in identical values but do not have this issue. Tested with FATE. Reviewed-by:

Current code is fine, this just adds robustness. Reviewed-by:

av_gcd is now always defined regardless of input. This documents this change in the "documented API". Two benefits (closely related): 1. The function is robust, and there is no need to worry about INT64_MIN, etc. 2. Clients of av_gcd, like av_reduce, can now be made fully correct. Currently, av_reduce can trigger undefined behavior if e.g num is INT64_MIN due to integer overflow in the FFABS. Furthermore, this undefined behavior is completely undocumented, and could be a fuzzer's paradise. The FFABS was needed in the past as av_gcd was undefined for negative inputs. In order to make av_reduce robust, it is essential to guarantee that av_gcd works for all int64_t. Reviewed-by:

This ensures that no undefined behavior is invoked, while retaining identical return values in all cases and at no loss of performance (identical asm on clang and gcc). Essentially, this patch exchanges undefined behavior with implementation defined behavior, a strict improvement. Rationale: 1. The ideal solution is to have the return type a uint64_t. This unfortunately requires an API change. 2. The only pathological behavior happens if both arguments are INT64_MIN, to the best of my knowledge. In such a case, the implementation defined behavior is invoked in the sense that UINT64_MAX is interpreted as INT64_MIN, which any reasonable implementation will do. In any case, any usage where both arguments are INT64_MIN is a fuzzer anyway. 3. Alternatives of checking, etc require branching and lose performance for no concrete gain - no client cares about av_gcd's actual value when both args are INT64_MIN. Even if it did, on sane platforms (e.g all the ones FFmpeg cares about), it produces a correct gcd, namely INT64_MIN. Reviewed-by:
