271e49577Rod Evans# libmd provides two families of optimized functions for SPARC platforms,
281e49577Rod Evans# one for sun4u, and one for sun4v.  Previous implementations provided
291e49577Rod Evans# these families as libmd_psr.so.1 libraries, triggered by tagging libmd.so.1
301e49577Rod Evans# as an auxiliary filter.  These psr filtees were installed under
311e49577Rod Evans# /usr/platform/sun4u/lib, and numerous symlinks were established to provide
321e49577Rod Evans# the necessary $PLATFORM names, ie:
331e49577Rod Evans#
341e49577Rod Evans#  /usr/platform/SUNW,Ultra-2/lib/libmd_psr.so.1 -> ../../../sun4u
351e49577Rod Evans#  /usr/platform/SUNW,Ultra-4/lib/libmd_psr.so.1 -> ../../../sun4u
361e49577Rod Evans#  ....
371e49577Rod Evans#

391e49577Rod Evans#
401e49577Rod Evans#  /usr/platform/SUNW,Netra-CP3060/lib/libmd_psr.so.1 -> ../../sun4v
411e49577Rod Evans#  /usr/platform/SUNW,Netra-CP3260/lib/libmd_psr.so.1 -> ../../sun4v/
421e49577Rod Evans#  ....

441e49577Rod Evans# The objects that made up these filtees are now combined into one relocatable
451e49577Rod Evans# object, pics/objcap.o, using ../common/mapfile-cap.  This mapfile identifies
461e49577Rod Evans# the machine hardware name, together with establishing the global symbols that
471e49577Rod Evans# should be exported to define each family.
481e49577Rod Evans#
491e49577Rod Evans# This object capabilities relocatable object is then translated into a symbol
501e49577Rod Evans# capabilities relocatable object, pics/symcap.o.
