TL;DR - link-set is fine if used with linker script

• link-set is a set of macros __link_set_* defined in sys/cdefs.h (actually sys/cdefs_*.h).

• link-set provides format-neutral way to generate linker sections.

• link-set relys on the feature of ld(1) that ld(1) automatically generates __start_XXX and __stop_xxx symbols for sections not starting . (hoge matches, .fuga does not).

• Those two symbols are only generated at final link. Not generated at relocatable output (ld -r).

Debugging

Use ld -Map=xxx.map and check the output. (Intuitive, no explanation needed.)

SECTIONS command: *(x y) vs *(x) *(y)

*(x y) merges sections by placing matched sections in the order they found.

*(x) *(y) merges sections by placing sections x first, then y
