27*1e49577aSRod Evans# libmd provides two families of optimized functions for SPARC platforms,
28*1e49577aSRod Evans# one for sun4u, and one for sun4v.  Previous implementations provided
29*1e49577aSRod Evans# these families as libmd_psr.so.1 libraries, triggered by tagging libmd.so.1
30*1e49577aSRod Evans# as an auxiliary filter.  These psr filtees were installed under
31*1e49577aSRod Evans# /usr/platform/sun4u/lib, and numerous symlinks were established to provide
32*1e49577aSRod Evans# the necessary $PLATFORM names, ie:
33*1e49577aSRod Evans#
34*1e49577aSRod Evans#  /usr/platform/SUNW,Ultra-2/lib/libmd_psr.so.1 -> ../../../sun4u

44*1e49577aSRod Evans# The objects that made up these filtees are now combined into one relocatable
45*1e49577aSRod Evans# object, pics/objcap.o, using ../common/mapfile-cap.  This mapfile identifies
46*1e49577aSRod Evans# the machine hardware name, together with establishing the global symbols that
47*1e49577aSRod Evans# should be exported to define each family.
48*1e49577aSRod Evans#
49*1e49577aSRod Evans# This object capabilities relocatable object is then translated into a symbol
