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