Lioncache aaca8772bd Utils/File: Properly handle move assignment/construction 
Ensures that whenever a file handle is transferred anywhere, that the
moved from instance won't end up closing the file handle when the
destructor runs.

Pierre-Loup A. Griffais 673a387808 DiskCache: hash guest code according to its real extents 
Does less hashing, improves hit rate when there's data adjacent to code,
and/or when the SMC check makes us rebuild code that hasn't actually been
changed.

Ryan Houdek 66cad978c3 FEXCore: Removes syscall optimization 
The JIT was doing a bunch of additional work where it was saving and
restoring registers and then juggling the arguments back in to a stack
frame. All of this is nonsensical without the optimization where we
could call syscalls inline without a stack frame.

Instead remove this optimization entirely and behave like a "generic"
syscall path always. The Linux syscall handler now pulls the arguments
out of the CPU context directly and stores the result back in to RAX
directly as well.

This has knock-on effects where technically syscalls are
going to be slightly faster because no stack frame setup for the
arguments, but additionally we are going to be able to have syscalls be
proper serialization points where we can interrupt the syscall and
long-jump out without problems.

Bumps the DiskCache version again because it causes codegen to change.

Ryan Houdek 2f663db52c Scripts/fit_native: Classify Oryon-1/3 
If the compiler is new enough than classify Oryon-1. Clang doesn't
support Oryon-3 so just claim its Oryon-1 in that case.

InstCountCI: Enforce DiskCache version matching
 2026-08-30 17:41:35 -04:00
Ryan Houdek b695c5ae11 InstCountCI: Update

Ryan Houdek f5935b4006 InstCountCI: Enforce DiskCache version matching 
Two added failure modes here. If the disk cache version has changed then
the json files must be updated to the new version to ensure correct
tracking.

Additional failure mode is that codegen actually changed but the disk
cache version hasn't. This is the expected common failure mode and we
need to do additional work before updating json results. This just means
incrementing the disk cache version before updating the instcountci
results. Have a fairly lengthy error message to showcase how much of an
impact this might have.

Ryan Houdek 83ead40b78 UnixLib: Removes old non-unixlib handling 
Everything that we care about supports the unixlib path now. Also turns
out we were doing `svc #0` on Windows when unixlib didn't exist which is
kind of funny.

Remove the legacy hacky path as it is no longer necessary.

DiskCache: Apply relocations from disk blob
 2026-08-28 17:58:41 -04:00
Ben Niu 9742a560f5 Resolve symlinks continuously until we find the actual binary name. 
When a guest executable is invoked through two or more levels of symlink,
FEX expands $ORIGIN in its DT_RPATH/DT_RUNPATH to the directory of the
intermediate symlink rather than the directory of the fully-resolved binary.
Libraries referenced relative to $ORIGIN then fail to load.

This PR fixes the issue by continuously chasing the symlinks until we find
the actual executable name.
