When tsoome@ added skein support to the ZFS boot code and zfsloader, it resulted in an explosion in code size, running close to a number of limits. The default for the C version of skein is to unroll all loops for skein-256 and 512 Disabling the loop unrolling saves 20-28kb from each binary boot1.efi gptzfsboot loader.efi userboot.so zfsloader Reviewed by: emaste, tsoome Sponsored by: ScaleEngine Inc.
