This test relies on non-concurrent optimizations to precisely test transitions between the different tiers. Disable flags that invalidate this test: --no-always-opt to test transiation from Ignition to Sparkplug --deopt-every-n-times=0 to test transition from Sparkplug to TF Bug: v8:11656 Change-Id: I85047015d3f7cfdf00bddad59c9742d5d8f5d223 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2827902 Auto-Submit: Patrick Thier <pthier@chromium.org> Reviewed-by: Michael Achenbach <machenbach@chromium.org> Commit-Queue: Michael Achenbach <machenbach@chromium.org> Cr-Commit-Position: refs/heads/master@{#73978}
