Comment on attachment 349143 [details] Patch r=me. I think you should remove Signature::firstValidIndex since it is no longer used.

Comment on attachment 349143 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=349143&action=review Nice change. The only thing that's weird to me is that we're still calling it an index. We should revise the name since the old name indicated an implementation style. But we're no longer using it as an index. Maybe we could call it something like UniqueSignature. > Source/JavaScriptCore/ChangeLog:20 > + This change significantly optimizes JS to wasm calls (1e7 times) from 600ms to 320ms. Our wasm entry is so slow :(
