Comment at: llvm/lib/CodeGen/MLRegallocEvictAdvisor.cpp:468-469
+ if (Log->currentContext() != MF.getName()) {
+ MF.getFunction().getContext().emitError(
+ "The training log context shouldn't have had changed.");
+ }
----------------
I think I am hitting this for cases where `RegAllocGreedy` bails out early in the `if (!hasVirtRegAlloc()) return false;` check and never initializes the advisor.
Replacing with `Log->switchCurrentContext()` for my experiments...
