[PATCH] D142168: [mlgo] Stream the training data

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added inline comments.


================
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...
