When the profile data comes from dynamic PGO, the spanning tree encoded in the schema produced by an earlier tier should exactly match the spanning tree for the current jit attempt, since the JIT and method IL are identical.

(This is not the case for static PGO; that schema may have come from a different JIT and/or different version of IL).

Note in release modes we won't assert; instead, we will silently throw the PGO data away.

Follow-on change to #85805 to catch more issues like #85799.

This replays cleanly with latest SPMI collections, so hopefully #85873 and #85860 have fixed the outstanding issues.

Will run some of the PGO stress legs here, once the basic CI is happy. Those are not completely clean.

When the profile data comes from dynamic PGO, the spanning tree encoded in the schema produced by an earlier tier should exactly match the spanning tree for the current jit attempt, since the JIT and method IL are identical.

(This is not the case for static PGO; that schema may have come from a different JIT and/or different version of IL).

Note in release modes we won't assert; instead, we will silently throw the PGO data away.

Follow-on change to #85805 to catch more issues like #85799.

This replays cleanly with latest SPMI collections, so hopefully #85873 and #85860 have fixed the outstanding issues.

Will run some of the PGO stress legs here, once the basic CI is happy. Those are not completely clean.
