Previously reported as some old CPU without AVX and SSE4 and other
things.
Start advertising as something more modern that actually shipped with
AVX2 and other features. Should help some modern libraries that do bad
family and model checks rather that CPUID features checks.
Also removes the silly `(ES)` tag from CPU-Z.
Also moves generation in to a constexpr function that can actually range
check these 4-bit and 8-bit values.
Only doing the single table for review purposes. Once reviewed I will
hammer out the remaining tables.
Similar to #3320, most of the OpcodeDispatcher tables can be consteval
and made to be a compile time constant. This just requires shuffling the
code slightly. The idea is to get almost all of the table setup out of
the `InstallOpcodeHandlers` function and instead only install the
handlers that change based on 32-bit or 64-bit, just like the x86 tables
we also did.
No functional change here.
- CoreRunningMode enum and variable wasn't used anymore.
- Code was moved to the frontend
- CustomCPUFactory wasn't used anymore
- All special signal handling and various features were moved to
TestHarnessRunner
- We also don't want to support actual custom CPU cores.
- TestHarnessRunner just runs as a host runner if compiled on an
x86-64 device if vixl sim isn't enabled now.
- Removes the Core config option entirely.
- Moves VDSOPointers struct to the frontend
- Every use of this lives in the Linux frontend instead now
This is one of the most expensive headers in FEX, averaging 1.2 seconds
of compile time per include.
We include this header 31 times around the project. Remove
the five instances where it is unused to help this issue. Next step
would be to make the header lighter if possible.
When the shift amount is >= 16-bytes then we need to zero the register.
We had a bug where we were assigning `Result.High` to itself, which
effectively made the top 128-bits of the ymm register not modify itself.
Adds a unit test to ensure that doesn't happen again.
more efficient to pool the output of constant folding and such. but we need to
avoid that becoming accidentally quadratic, so rework that too

it's only really load bearing for pf/af, which is handled as a global flag opt
now. this mitigates some of the compile time hit from globalizing flag opts.

another global CFG-based optimization -- if we know that the raw PF is already
1-bit we can skip parity evaluation, saving work with floating point compares.
