Billy Laws ef823ce82b OpcodeDispatcher: Allow x86 code to read CNTVCT on ARM64EC 
Required by newer insider preview versions, I noticed many crashes with
this exception number and QueryPeformanceCounter in the backtrace,
testing with XTA found it to not be passed through and instead write
the host CNTVCT (unscaled) into RAX. No other registers seem to be
affected.

Ryan Houdek 0ec724cf1f HostFeatures: Moves MIDR querying to the frontend 
The MIDR querying is inherently OS specific and needs a bit of special
casing. Instead let the frontend inform FEXCore how many CPU cores there
are and their MIDRs instead.

This lets us keep the Linux specific code in the frontend.

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.
