Hello, There is a bug in the current version of vorbis/lib/floor1.c. The line that says:- qsort(sortpointer,n,sizeof(int),icomp); should be:- qsort(sortpointer,n,sizeof(int *),icomp); But somebody probably fixed that already. :) Also, I'd like to know how I can encode a file using the channel coupling modes. oggenc doesn't have an option for that yet. Greetings, Michael. -- This message may have...

...= add i32 %11, %4 ..... This Loop optimization can reduce the loop to only one instruction for every 4 or 8 or 16 iterations of the loop ( depending on the target sad instruction). Proposed Solution The sad pattern shown above which is the abs pattern with reduction variable ( sequence of sub, icomp, sub, select, add ) can be replaced with an intrinsic call. For a non-unrolled loop we can do this in LoopVectorization where all the infrastructure for identifying reduction variables is already there. We just need to identify the sad pattern, remove those instructions and call an intrinsic. This...
