Bug 211198 – REGRESSION (r260802-r260858): stress/rest-parameter-many-arguments.js.ftl-no-cjit-small-pool and stress/tailCallForwardArguments.js.ftl-no-cjit-small-pool timing out on JSC debug bot

• Status: NEW
• Component: JavaScriptCore

[Ryan Haddad]

The following two tests are timing out on JSC debug bot:

stress/rest-parameter-many-arguments.js.ftl-no-cjit-small-pool
stress/tailCallForwardArguments.js.ftl-no-cjit-small-pool

Because of https://bugs.webkit.org/show_bug.cgi?id=210063, we don't have a lot of test result granularity to sift through.

Here is the regression range:

This range was starting with the last successful run with no failures, but I don't think I can trust that result (it doesn't look like it ran all the tests?)

Here are the JSC changes between the last run with a verifiable result that didn't exhibit the timeouts and the first one that did:
