When TurboFan doesn't know anything about the receiver, it will generally insert a call via CallFunctionTemplate builtin, which does all the necessary checks. For this we don't need to be able to deoptimize, so there's no need to have the speculation bit available. This restores the performance in the case of calling API methods and accessors via `Function#call()`, i.e. like in this example: ```js const hasAttribute = Element.prototype.hasAttribute; // ... hasAttribute.call(element, "bar"); ``` Bug: v8:8820 Change-Id: Ic30719d7db75141023efc11d76180b001f871d28 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1615248 Auto-Submit: Benedikt Meurer <bmeurer@chromium.org> Commit-Queue: Georg Neis <neis@chromium.org> Reviewed-by: Georg Neis <neis@chromium.org> Cr-Commit-Position: refs/heads/master@{#61604} |
