Hi v8-dev, I was debugging something that was causing me to place extra GCs and saw that it was causing a ton of spurious turbofan recompilation of functions and deopts referencing weak objects. After digging a bit it looks like v8 only keeps a weak reference to optimized code in https://github.com/v8/v8/blame/main/src/objects/feedback-vector.cc#L368
It looks like it's done this from the beginning per https://github.com/v8/v8/commit/11a211ff1b81e8d83d1aa4898743c2efb89603bd#diff-cbddb8a6da7810e9fc3647c9cf4f511410c43d11da9f62873bc33dece03a31f5R305 I'm writing a CLI using node and I'm willing to trade memory for speed. Is this a contribution that makes sense behind an experimental flag? -- -- v8-dev mailing list [email protected] http://groups.google.com/group/v8-dev --- You received this message because you are subscribed to the Google Groups "v8-dev" group.
