The switch itself then pages the provider in through the normal pool path. +The reverse direction is in the xrefs dialog. `xrefs_to` only ever sees the +current database, so an exported function looks unused from the inside even when +half the project calls it. `_foreign_importers` appends the project binaries that +IMPORT the symbol — read from the on-disk index, so a caller shows up whether or +not its worker is resident — and choosing one carries a `(binary, addr)` payload +through the same switch path as a search hit, hop included. From libc's +`strrchr`: `0000C318 import [echo] strrchr`. + +It only fires for a symbol this binary actually exports. A local name that +happens to collide with another binary's import is not a caller of ours. + When nothing in the project provides the symbol, `_follow_import` declines and the local navigation proceeds — landing on the stub is still the honest answer, and a single-binary session behaves exactly as before. |
