# To support the Sun linker we need to make it behave like the GNU linker |
|
# for orphaned sections. That means generating __start/__stop symbols |
|
# for them and that means some nopoly-atheist-withoutfood level trickery. |
|
# We enumerate all the section names we wish to generate symbols for. |
|
# The good news is that it's unlikely for NetBSD to grow any more |
|
# link sets, and even if it does, it'll be a build-time failure |
|
# on Sun platforms so it's easy to catch and mend the list below. |
