common: pass-through hash for integer and pointer keys; RangeSet::Intersects

2026-10-30T00:49:47+00:00

Common::unordered_map/set defaulted to std::hash, a byte-wise FNV-1a on MSVC for integers and pointers, which boost's flat containers then mix again: the GPU thread's page maps (shader and query cache invalidation, per inline upload) spent ~1% in it. Integer and pointer keys now go through as they are and boost mixes them. BufferCache::IsRegionGpuModified visited every GPU-written range inside the query just to answer yes or no; without per-fence downloads those ranges stay fragmented and it was ~4% of title 1's GPU thread (inline uploads). RangeSet::Intersects answers with one lookup. Inline uploads: 10.5% -> 7.5% of the GPU thread.

[common] Switch to boost::unordered_flat containers (#4326)

2026-08-31T00:58:09+00:00

Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.
