Thanks for the testing. > I noticed a side effect for this change. Encoding got a bit slower at > least when md5 checksumming is enabled. That's odd. How much slower was the encoding? Could it be caused by increase in the size of the function (only with -funroll-loops?) and not fitting in the cache during encoding? It might be good to use -funroll-loops only with some files, IIRC it helped most to stream_encoder.c. -- Miroslav Lichvar _______________________________________________ flac-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac-dev
