Lioncache 3e741df77b SyscallHandler: Avoid self-referencing global 
We don't need to indirect through the handler global inside of the class
itself for instance member functions.

Ryan Houdek 31d4b4a201 Merge pull request #4960 from Sonicadvance1/enable_avx_32bit 
HostFeatures: Enable AVX for 32-bit by default
 2025-10-10 10:31:55 -07:00
Lioncache e83e9cb6b3 JSONPool: Make allocator funcs internally linked 
Makes it a little more explicit that these aren't used outside of this
TU.
 2025-10-10 00:11:17 -04:00
Lioncache 987fc925ee FileManagement: Use emplace instead of insert for set 
These are cases where the string can be directly constructed internally
instead of being copied/moved.
 2025-10-09 22:02:06 -04:00
Lioncache b6cbb23781 FileManagement: Make use of std::string_view in LoadThunkDatabase() 
Same behavior, but avoids allocating except for the case where its
necessary.
 2025-10-09 22:02:03 -04:00
Ryan Houdek 832d1e8d2c HostFeatures: Enable AVX for 32-bit by default 
With the gather overflow fixes in place, I've been having this running
for a while. Now that we just kicked out a release, enable AVX even on
32-bit.

We'll need to eventually create a list of games that explode with AVX
enabled, but that same list would match what happens on real x86 hosts,
so there can be some collaboration there.

Jacek Caban 5fd3852fd3 ARM64EC: Emulate unaligned atomic access in non-JIT EC code 2025-10-10 00:13:56 +02:00
Lioncache 55c43229ca Config: Remove unnecessary check in GetConfigDirectory() 
This is already checked for in the outer if.
 2025-10-09 14:57:00 -04:00
Lioncache dbc4daaaa4 Config: std::move string into EnvMap 
Same behavior, but without a reallocation.
 2025-10-09 14:57:00 -04:00
Lioncache acdbbec78d Config: Prevent duplicate lookup in EnvLoader::Load() 
We can check the iterator itself instead of doing the lookup again.

Lioncache 17d110575c BPFEmitter: Remove unused SeccopEmulator include 2025-10-09 00:57:49 -04:00
Lioncache a967976420 BPFEmitter: Simplify iterator declarations 
Makes the jump labels a little quicker to read.
 2025-10-09 00:57:49 -04:00
Lioncache 7e1e1ccccc BPFEmitter: Move private API into implementation 
Keeps some internals fully private (and also avoids dumping
some defines into other headers).
 2025-10-09 00:57:49 -04:00
Lioncache 8513c02ec1 ELFParser: Avoid unnecessary copies 
Gets rid of a few 56 byte copies.
 2025-10-08 21:20:46 -04:00
Ryan Houdek 673e826e46 FEX: Remove InlineSyscall and related flags 
FEXCore no longer optimizes syscalls to be inline.

NFC, just avoids passing around a bunch of data structures for no
reason.

Ryan Houdek 3b88947cbe Merge pull request #4950 from lioncash/syscall 
SyscallHandler: Shrink definition struct from 24 to 16 bytes
 2025-10-08 14:03:57 -07:00
Lioncache 10c3b2fb5d SyscallHandler: Shrink definition struct from 24 to 16 bytes 
Just a minor space saving, given how many syscall definitions we'll
have.
 2025-10-08 16:40:20 -04:00
Lioncache 74ae89865c SHMStats: Add missing virtual destructor 
This should be present for universally consistent behavior, regardless
of how the class is used.
 2025-10-08 16:17:42 -04:00
Lioncache a2445904e7 ThreadManager: Make StatAlloc instance private 
This doesn't need to be public.
 2025-10-08 16:13:23 -04:00
Lioncache d94b9fae94 SourceCodeResolver: Pass string_view by value for GenerateMap() 
Generally this should be passed as a value type unless there's a good
reason not to.
 2025-10-07 01:27:15 -04:00
Lioncache 05fcaaa758 Syscalls: Remove unimplemented prototypes 2025-10-07 01:27:11 -04:00
Ryan Houdek 2cab87fbd0 ThreadManager: Fix mmap usage to not take guest space 
SHM stats and CallRet stack was accidentally using system mmap which
means it would take VA space from the guest. Ensure it uses the
Allocator helpers so that doesn't happen.

Gives 32-bit guests 8-ish megabyte of VA space back.

Lioncache 137aa59254 PrctlUtils: Move to include folder 
We can group more prctl value handling in here.

Billy Laws 70cffce5eb Windows: Avoid redeclaring strtoll as unimplemented 
Included as part of the musl code we pull in. Fixes ARM64EC/WOW64 FEX.

LC 18d0dec416 Merge pull request #4911 from Sonicadvance1/evmd_linux 
Linux: Implement support for extended volatile metadata
 2025-09-30 20:01:26 -04:00
Ryan Houdek b08e5f9821 Linux: Implement support for extended volatile metadata 
Allows applications running entirely under Linux to use the same
extended volatile metadata as Windows.

For example `FEX_EXTENDEDVOLATILEMETADATA=iw4sp.exe\;0xe9da0-0xe9ec7`
this configuration works for both wow64 and Linux to disable the TSO
emulation on the memcpy routine in that game that consumes around 80% of
CPU time in TSO emulation.

Works with Linux native games as well of course.
 2025-09-29 14:36:51 -07:00
Ryan Houdek 1758648f56 Common: Move ApplyFEXExtendedVolatileMetadata to Common 
It is going to be used by Linux.

Also adds support for file offset handling, which is required on Linux
but not on win32.
 2025-09-29 14:36:50 -07:00
Ryan Houdek 418ce0aed9 Wow64: Ensure extended volatile metadata is removed 
Was missing this, matches the arm64ec side.

Billy Laws 73962402df TestHarnessRunner: Don't attempt to build on MinGW 2025-09-24 20:28:33 +01:00
Paulo Matos e7a47a647c Fix quiet and signalling nan propagation 
This adds a new mode X87StrictReducedPrecision.
The strict reduced precision is like the reduced precision but adds extra checks,
like the currently implemented nan and snan propagations.

Fix for __builtin_issignaling() test of SPEC2017 classify test.

Ryan Houdek dd4f508b77 FEX: Fixes SIGILL reporting 
Two bug fixes here.
- We weren't reporting a correctl ErrorRegister. Needs to contain
  PF_INSTR at least.
- We weren't setting siginfo->si_addr in the case of `FaultToTopAndGeneratedException`

Fixes Mafia 2 (Classic)

Ryan Houdek de6d907e27 SignalDelegator: Correctly save and restore x87 state. 
We need to read the current x87 TOP location and rotate the values when
saving and restoring the context state on Linux. Wasn't visible in the
ASM tests since we read the FEX's CPU state directly there.

Ryan Houdek 85e67f92c5 FEX: Rebrand FEXInterpreter as FEX 
Still creates a copy of FEXInterpreter from FEX for downstream projects
to have some time to get off the old name. Creating a symlink is kind of
a pain in cmake so just doing an install copy is easy.

Ryan Houdek 7273041314 FEXInterpreter: Remove FEXLoader 
Doesn't /quite/ remove the ArgumentLoader because it is intertwined with
LinuxEmulation in an annoying way that will take another step to remove.

ArgLoader is going to get removed. So delete this menial usage of it.

Ryan Houdek c966f44189 FEXRootFSFetcher: Removes argloader usage 
Another case that ArgLoader was misused.
 2025-09-11 12:20:28 -07:00
Ryan Houdek 193ef8b232 FEXServer: Remove usage of ArgLoader 
This is entirely unused as FEXServer only ever reads the environment and
other configs.

There was /technically/ a weird conflict with FEXServer arguments but
that was an accident if it ever happened.

NFC

FEXInterpreter is the supported path, rename things to reflect that.
