Ryan Houdek 689b461d7b Merge pull request #3984 from Sonicadvance1/atomic_tso_subchecks 
FEXCore: Splits up atomic enablement checks
 2024-08-20 15:16:54 -07:00
Ryan Houdek 9c8438f264 FEXCore: Splits up atomic enablement checks 
PR #3980 is adding a feature to merge loadstores in to paired
loadstores, but it was using the incorrect atomic check to determine if
it can safely merge them or not. It was using the GPR atomic check
instead of the vector atomic check. While this would improve performance
on Apple Silicon with its hardware TSO implementation, it would have had
zero impact on Cortex and Oryon.

Instead split out the three config options to live as a boolean check in
the ContextImpl similar to how we disable "AtomicTSOEmulation". Removing
the various configs in the JIT and CPUID so that it queries from the
same context. This makes it clearer that if you are wanting the current
active configuration for memcpy, vector, or general atomic TSO
emulation, you should query one of those three getters.

This also fixes a weird edge case bug in the arm64 JIT where you could
have TSO emulation disable, but still have vector TSO enabled partially.
Just because half a config wasn't checked in {Load,Store}MemTSO for
vectors. If the global "TSOEnabled" option is disabled then TSO should
always be disabled.

Alyssa will be able to pull this in to #3980 once merged and get the
performance uplift on Cortex and Oryon, since our default configuration
is to have vector and memcpy TSO emulation disabled.

Ryan Houdek 2eb7a9ff28 OpcodeDispatcher: Remove old bad assumption in INC/DEC 
Somewhere there was an assumption made that INC and DEC supported the
repeat prefix. This isn't actually the case, while the prefix can be
encoded, it is a nop and should only expect to be used for padding.

Adds a unittest to ensure that behaviour is as expected.
