// This file defines a verifier which is useful for enforcing the relocation
// properties required by a relocating GC. Specifically, it looks for uses of
// the unrelocated value of pointer SSA values after a possible safepoint. It
// attempts to report no false negatives, but may end up reporting false
// positives in rare cases (see the note at the top of the corresponding cpp
// file.)
