# Rules to build add_gnu_debuglink, used by vm.make on Solaris

# compare the built ELF objects.
#
# The -g option makes static data global and the "-W0,-noglobal"
# option tells the compiler to not globalize static data using a unique
# globalization prefix. Instead force the use of a static globalization
# prefix based on the source filepath so the objects from two identical
# compilations are the same.
#
# Note: The blog says to use "-W0,-xglobalstatic", but that doesn't
#       seem to work. I got "-W0,-noglobal" from Kelly and that works.
