The original CL introduced a test that does not work when it is executed concurrently on multiple isolates. This CL skips this test configuration. Original change's description: > [wasm] Lazy compilation after deserialization > > The serialization format contains one boolean flag per function which > specifies whether the function code exists in the serialized module or > not. With this CL, this boolean flag is extended to a three-value flag > which indicates whether the function exists, and if not, whether the > function was executed before serialization. This information can then be > used upon deserialization to compile only those functions that were > executed before serialization. > > Design doc: https://docs.google.com/document/d/1U3uqq4njqLqFhr1G2sU_bmpQxY-3bvfG55udSb-DvA4/edit?usp=sharing > > Bug: v8:12281 Change-Id: I36ce90b37736172aa01c47ab04e154ec8ea2d8aa Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3380590 Reviewed-by: Clemens Backes <clemensb@chromium.org> Commit-Queue: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/main@{#78564}
