250 +# and useful for --gc-sections, which for a variable "foo" might be
251 +# ".data.foo". Then there are the linkonce sections, for which the linker
252 +# eliminates duplicates, which are named like ".gnu.linkonce.d.foo".
253 +# The exact correspondences are:
254 +#
255 +# Section Linkonce section
