LibWeb: Add ProcessingInstruction node Not particuarly useful right now, but is used in ensure_pre_insertion_validity. I'm not totally sure on the constructor arguments.

LibWeb: Make sure ProcessingInstruction objects have the right prototype
2022-12-13 09:24:27 -03:00
#include <LibWeb/Bindings/Intrinsics.h>
LibWeb: Remove Bindings/Forward.h from LibWeb/Forward.h This was resulting in a whole lot of rebuilding whenever a new IDL interface was added. Instead, just directly include the prototype in every C++ file which needs it. While we only really need a forward declaration in each cpp file; including the full prototype header (which itself only includes LibJS/Object.h, which is already transitively brought in by PlatformObject) - it seems like a small price to pay compared to what feels like a full rebuild of LibWeb whenever a new IDL file is added. Given all of these includes are only needed for the ::initialize method, there is probably a smart way of avoiding this problem altogether. I've considered both using some macro trickery or generating these functions somehow instead.

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

GC_DEFINE_ALLOCATOR(ProcessingInstruction);
LibWeb: Put most LibWeb GC objects in type-specific heap blocks With this change, we now have ~1200 CellAllocators across both LibJS and LibWeb in a normal WebContent instance. This gives us a minimum heap size of 4.7 MiB in the scenario where we only have one cell allocated per type. Of course, in practice there will be many more of each type, so the effective overhead is quite a bit smaller than that in practice. I left a few types unconverted to this mechanism because I got tired of doing this. :^)

LibWeb: Avoid FlyString lookups when setting IDL interface prototypes This commit introduces a WEB_SET_PROTOTYPE_FOR_INTERFACE macro that caches the interface name in a local static FlyString. This means that we only pay for FlyString-from-literal lookup once per browser lifetime instead of every time the interface is instantiated.

WEB_SET_PROTOTYPE_FOR_INTERFACE(ProcessingInstruction);
LibWeb: Only set prototype once for object with IDL interface Before this change, we were going through the chain of base classes for each IDL interface object and having them set the prototype to their prototype. Instead of doing that, reorder things so that we set the right prototype immediately in Foo::initialize(), and then don't bother in all the base class overrides. This knocks off a ~1% profile item on Speedometer 3.
