These inline implementations of AV_COPY64, AV_SWAP64 and AV_ZERO64 are known to clobber the FPU state - which has to be restored with the 'emms' instruction afterwards. This was known and signaled with the FF_COPY_SWAP_ZERO_USES_MMX define, which calling code seems to have been supposed to check, in order to call emms_c() after using them. See |
