Every cross-reference used to need a hand-written config/symbols.tsv row, which
does not scale to a batch. A symbol whose name is an address now resolves to that
address with no row: func_XXXXXXXX, D_XXXXXXXX, g_XXXXXXXX, lbl_XXXXXXXX. This is
the convention the registry already used, applied without the row.
The names come from the object's own undefined-symbol list (nm -u), not from a
guess about the source, so a name the source defines but never references is
never mistaken for one needing resolution. A registry row still wins, which is
how a gp marker or a real name is attached. Anything neither registered nor
address-shaped now fails before the link with a message naming the symbol and the
fix, instead of a bare ld diagnostic.
First match from the worklist: func_800F8F9C (36 bytes, worklist rank 3), a
duplicate-group representative with a frame and a call. It matched on the first
attempt and is registered twice (0x800F8F9C, 0x80109314) against one source, so
two functions were matched for one body. Its callee needed no registry row.
Ghidra's independent body agrees with the derived extent.
