Core: Don't create page table mappings before R/C bits are set

2026-02-04T20:35:22+00:00

This gets rid of the hack of setting the R and C bits pessimistically,
reversing the performance regression in Rogue Squadron 3.

Common/MemArena: Add function for getting page size

2026-02-01T11:39:32+00:00

Modernize `std::lower_bound`/`upper_bound` with ranges and projections

Common/MemArenaWin: Rewrite LazyMemoryRegion to manually map memory blocks into the large memory region as needed.

2023-12-09T20:11:31+00:00

Internal details: The large region is split into individual same-sized blocks of memory. On creation, we allocate a single block of memory that will always remain zero, and map that into the entire memory region. Then, the first time any of these blocks is written to, we swap the mapped zero block out with a newly allocated block of memory. On clear, we swap back to the zero block and deallocate the data blocks. That way we only actually allocate one zero block as well as a handful of real data blocks where the JitCache actually writes to.

Common/MemArenaWin: Move the advanced Windows memory function address initialization into its own struct and function so it can be reused.

Common/MemArena: A zero-byte allocation is invalid.

2023-09-07T12:41:24+00:00

Common/MemArena: Add LazyMemoryRegion to represent a zero-initialized memory region whose pages are only allocated on first access.

2023-09-02T02:02:10+00:00

Common/MemArena: Pass shared memory base file name to GrabSHMSegment().

2023-05-19T16:53:08+00:00

Common/MemArenaWin: Handle file mappings >= 4GB.
