Andreas Kling	a0864dbb26	LibJS: Make mapped arguments objects way less allocation-happy ... By following the spec to the letter, our mapped arguments objects ended up with many extra GC allocations: - 1 extra Object for the internal [[ParameterMap]]. - 2 extra NativeFunctions for each mapped parameter accessor. - 1 extra Accessor to hold the aforementioned NativeFunctions. This patch removes all those allocations and lets ArgumentsObject model the desired behavior in custom C++ instead of using script primitives. 1.06x speedup on Speedometer's TodoMVC-jQuery.	2025-05-11 14:00:40 +02:00
Andreas Kling	183c847c80	LibJS: Cache PutById to setters in the prototype chain ... This is *extremely* common on the web, but barely shows up at all in JavaScript benchmarks. A typical example is setting Element.innerHTML on a HTMLDivElement. HTMLDivElement doesn't have innerHTML, so it has to travel up the prototype chain until it finds it. Before this change, we didn't cache this at all, so we had to travel the prototype chain every time a setter like this was used. We now use the same mechanism we already had for GetBydId and cache PutById setter accesses in the prototype chain as well. 1.74x speedup on MicroBench/setter-in-prototype-chain.js	2025-05-05 15:21:43 +02:00
Shannon Booth	f87041bf3a	LibGC+Everywhere: Factor out a LibGC from LibJS ... Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root	2024-11-15 14:49:20 +01:00
