Ryan Houdek 474f2dc267 FEX: Name remaining allocations as "Misc" 
This captures the remaining FEX allocations that /aren't/ coming from
JEMalloc, allowing us to separate our mapped regions versus just
jemalloc allocations.

With some additional naming in jemalloc (which I'm not adding here) this
gets us interesting results:
```
        Misc resident:        54 MiB
    JEMalloc resident:        208 MiB
```

So 208MB of active jemalloc allocations in this particular case. These will be able to be tracked in heaptrack-like applications if careful.
This should let us target down whatever live allocations we're keeping
large amounts of data around if possible.

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.

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.

Lioncache 7e1e1ccccc BPFEmitter: Move private API into implementation 
Keeps some internals fully private (and also avoids dumping
some defines into other headers).

Lioncache 8513c02ec1 ELFParser: Avoid unnecessary copies 
Gets rid of a few 56 byte copies.

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.

Lioncache 10c3b2fb5d SyscallHandler: Shrink definition struct from 24 to 16 bytes 
Just a minor space saving, given how many syscall definitions we'll
have.

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.

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.

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.

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 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.
