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.

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.

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.

Ryan Houdek 418ce0aed9 Wow64: Ensure extended volatile metadata is removed 
Was missing this, matches the arm64ec side.

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.

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