1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# libmd provides two families of optimized functions for SPARC platforms,
1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# one for sun4u, and one for sun4v. Previous implementations provided
1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# these families as libmd_psr.so.1 libraries, triggered by tagging libmd.so.1
1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# as an auxiliary filter. These psr filtees were installed under
1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# /usr/platform/sun4u/lib, and numerous symlinks were established to provide
1e49577a7fcde812700ded04431b49d67cc57d6dRod Evans# the necessary $PLATFORM names, ie:
