DiskCache: optional memory buffer for faster lookups
 2026-09-18 13:27:25 -07:00
Pierre-Loup A. Griffais 7a82b07bfd DiskCache: optional memory buffer for faster lookups 
May reserve a tiny area for small blocks in general, but will also be useful
for LuaJIT in anon-diskless mode.

Leave the smaller public header that is required to get the current
DiskCache version variable still.

I forgot that we actually need this to match arm64 behaviour on x86.
Implement the pseudocodefor the instruction.

FEXCore: Moves crc32 helper to a shared location

Ryan Houdek 1167d0354a unittests/ASM: Manually encode some smsw tests 
Nasm 3.01 fails to encode these as we are expecting for our unittests,
resulting in incorrect results. Manually encode to test everything we
care about.

Davide Cunial 7403789d8b Update functional.h 
Update move_only_function to use std::invoke instead of regular C++ call syntax which is invalid for pointer-to-member-function call.

Pierre-Loup A. Griffais ae84606da2 InstcountCI: Update 2026-09-14 22:31:16 -07:00
Pierre-Loup A. Griffais 3f8f886f65 Frontend: patch cmp imm8 for cache 
Usually imm8 seem more likely to be a function of the code around them, but
this one seems used by Mono for varying data over execution of same code.
Maybe an ID of some kind.

Pierre-Loup A. Griffais 56a4f11ddb Frontend: avoid cache patching for certain cases with data unlikely to change 
The MOV heuristic shaves off a ton of patch sites (storage and overhead on
Lookup) where the data doesn't seem to change in practice.

Pierre-Loup A. Griffais 1695d742b1 DiskCache: on Store, make unaccounted-for DataMasks non-fatal 
By going through relocations before computing/hashing extents, we can simply
undo datamasks that haven't been claimed by the backend instead of failing
the whole Store. They fall back to being part of the normal hashed extents.

Pierre-Loup A. Griffais 5efc3212d2 JIT: Let DiskCache patch ValidateCode guest CRC
