Ryan Houdek e82d2c70c3 Merge pull request #4095 from alyssarosenzweig/opt/jit-time 
speed up the JIT
 2024-10-04 09:00:03 -07:00
Ryan Houdek 7dda75646d OpcodeDispatcher: Fixes segment prefixing on vector element loadstores 
These had completely forgotten to load segment prefixes on the element
loadstore operations. This had caused a crash on the Linux version of
"Halls of Tormet" (steamid 2218750).

This game has TLS vector data which it was loading with a movhps and hit
this path.

Alyssa Rosenzweig 44484a7b05 ConstProp: drop non-loadbearing opts 
every pattern costs us JIT time, but not every pattern is doing anything.
especially with the flag rework of 2023-2024, a lot of patterns just don't make
sense anymore. constant folding in particular isn't too useful now.

only instcountci change is AAD which i'm contractually forbidden from caring
about.

Alyssa Rosenzweig 36d0a67070 ConstProp: don't pool with a hash table 
hash tables have high overhead! but individual blocks are small, so the
quadratic search is _much_ faster in practice. knocks 8% off node.

Ryan Houdek 00a3793814 Config: Be a bit smarter in ReloadMetaLayer

bunch of string copies when they can just be pointers instead.

Ryan Houdek 58bcf691d6 Linux: Optimize CreateNewThread stack usage 
We were creating a copy of the FEXCore::Core::CPUState object when we
didn't need to. We can pass the host thread's CPUState frame through to
the creation handlers since it's read-only (so modify it to be const).

We then just move the RAX and RSP setting to /after/ the CreateThread
handling instead of before.
This reduces stack usage from ~1392 bytes to ~80 bytes.

Ryan Houdek e7605c94dd SignalDelegator: Let the frontend inform AVX support 
Since the frontend has changed to informing the backend if AVX is
supported, there is no reason to feed that configuration back in to
SignalDelegator from the backend.

Instead inform the SignalDelegator directly in the frontend instead of
this now weird round-about path.

Ryan Houdek ab5a10374b FEXCore: Remove BlockSamplingData 
This was a legacy interface that has long lost its implementation and
has long lost its use. This interface was similar to an older
Dolphin-Emu interface that was useful in that project, but isn't really
useful in a world with hundreds of threads and processes running at the
same time.
