Ryan Houdek 0a32ba9b29 instcountCI: Fixes for shifts 2024-09-08 18:03:20 -07:00
Ryan Houdek f51832ca6b FEXCore: Fixes a bug with VPSRLDQ/VPSLLDQ with >= 16-byte shifts 
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.

Alyssa Rosenzweig 67c751d3e5 JIT: always use 64-bit moves for SRA 
I see no reason not to. Simpler code and it's slightly faster on Firestorm.

Billy Laws 621af9e7e8 ARM64EC: Switch to exception-based native syscall dispatch 
The previous approach assumed that ntdll wouldn't have been patched
before FEX was loaded, but that isn't necessarily the case thanks to
CEF. This takes the same approach used by xtajit which wine recently gained
support for wine. The overhead to this isn't ideal but most syscalls
aren't directly done through x86 code anyway and in the future FEX could
forward unpatched thunks to their ARM variants at JIT time.

Billy Laws f7b911ca43 OpcodeDispatcher: Do not forbid INT 2E syscalls on 64-bit Windows 
This works fine on real Windows and is relied on by wine as SystemCall
is set to 1 in KUSER_SHARED_DATA, which causes the ntdll thunks to use
it over `syscall`
