Andreas Kling	3c74dc9f4d	LibJS: Segregate GC-allocated objects by type ... This patch adds two macros to declare per-type allocators: - JS_DECLARE_ALLOCATOR(TypeName) - JS_DEFINE_ALLOCATOR(TypeName) When used, they add a type-specific CellAllocator that the Heap will delegate allocation requests to. The result of this is that GC objects of the same type always end up within the same HeapBlock, drastically reducing the ability to perform type confusion attacks. It also improves HeapBlock utilization, since each block now has cells sized exactly to the type used within that block. (Previously we only had a handful of block sizes available, and most GC allocations ended up with a large amount of slack in their tails.) There is a small performance hit from this, but I'm sure we can make up for it elsewhere. Note that the old size-based allocators still exist, and we fall back to them for any type that doesn't have its own CellAllocator.	2023-11-19 12:10:31 +01:00

Brian Gianforcaro	e2d154c74d	LibJS: Use default instead of an empty constructor/destructor ... Default implementations allow for more optimizations. See: https://pvs-studio.com/en/docs/warnings/v832/	2021-09-16 17:17:13 +02:00
Ali Mohammad Pur	5a0cdb15b0	AK+Everywhere: Reduce the number of template parameters of IntrusiveList ... This makes the user-facing type only take the node member pointer, and lets the compiler figure out the other needed types from that.	2021-09-10 18:05:46 +03:00

Andreas Kling	9b699bad94	LibJS: Rename Allocator => CellAllocator ... Now that we have a BlockAllocator as well, it seems appropriate to name the allocator-that-allocates-cells something more specific to match.	2021-05-27 19:56:12 +02:00
