History

Andreas Rheinhardt bd50e715a9 avutil/common: Move everything inside inclusion guards ... libavutil/common.h is a public header that provides generic math functions whereas libavutil/intmath.h is a private header that contains plattform-specific optimized versions of said math functions. common.h includes intmath.h (when building the FFmpeg libraries) so that the optimized versions are used for them. This interdependency sometimes causes trouble: intmath.h once contained an inlined ff_sqrt function that relied upon av_log2_16bit. In case there was no optimized logarithm available on this plattform, intmath.h needed to include common.h to get the generic implementation and this has been done after the optimized versions (if any) have been provided so that common.h used the optimized versions; it also needed to be done before ff_sqrt. Yet when intmath.h was included from common.h and if an ordinary inclusion guard was used by common.h, the #include "common.h" in intmath.h was a no-op and therefore av_log2_16bit was still unknown at the end of intmath.h (and also in ff_sqrt) if no optimized version was available. Before a955b59658 this was solved by duplicating the #ifndef av_log2_16bit check after the inclusion of common.h in intmath.h; said commit instead moved these checks to the end of common.h, outside the inclusion guards and made common.h include itself to get these unguarded defines. This is still the current state of affairs. Yet this is unnecessary since 9734b8ba56 as said commit removed ff_sqrt as well as the #include "common.h" from intmath.h. Therefore this commit moves everything inside the inclusion guards and makes common.h not include itself. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>		4 years ago
