We were not doing so in all cases, which could lead to reordering a throw with a store.

Small diffs where we no longer hoist across a global store.

Issue Details

We were not doing so in all cases, which could lead to reordering a throw with a store.

We're expecting some small diffs where we no longer hoist across a global store.

Assuming CI failures are not related:

  1. Linux ARM - System.Text.Json.SourceGeneration.Roslyn3.11.Tests crashes due to an assertion on linux/arm64/debug #65817.
  2. OSX x64 - Profiler.Tests.GCBasicTests test failure #67106.
  3. Windows ARM64 - same failure mode as here (which was for a comment-only change).
