/* Property sections are marked "KEEP" in the linker scripts, but they
should not cause other sections to be marked. (This approach relies
on elf_xtensa_discard_info to remove property table entries that
describe discarded sections. Alternatively, it might be more
efficient to avoid using "KEEP" in the linker scripts and instead use
the gc_mark_extra_sections hook to mark only the property sections
that describe marked sections. That alternative does not work well
with the current property table sections, which do not correspond
one-to-one with the sections they describe, but that should be fixed
someday.) */
