To clarify on this, using a 32-bit memory operand means the calculated effective address will be 32-bit, not 64-bit, so if the result exceeds 0xFFFFFFFF it will be truncated and zero-extended (not even sign-extended like most other x86 things!). It's essentially i big trap because it really doesn't do what you'd expect it do to. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
