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.

Newer compiler and libraries got angry that these were missing.

LC 37c809471b ElfContainer: Amend entry iteration in GetDynamicLibs()
These were using i in the termination condition, which is for section
headers, not entries.

Tony Wasserka c67ffb82a8 Core: Support reporting blocks that are uncacheable due to unhandled ELF relocations 2026-03-18 11:59:44 +01:00
Tony Wasserka 1ea24f3d6c LinuxSyscalls: Enable delayed code cache load for ELF files
Specifically this is needed if any ELF relocations cover read-only code
sections, which is indicated in the ELF headers via DT_TEXTREL/DF_TEXTREL.

crueter 588fec3b89 [cmake] reduce usage of trivial variables
Trivial variables like SRCS, NAME, etc. actually do more harm than good.
They *will* make your IDE mad, and are also less readable. Remember:
verbosity is not a bad thing! Usually

Also: did a few tiny cleanups that I missed from my `endpara` PR.

crueter 43173df446 [cmake] prefer end parenthesis on same line, no space after some calls
- Some CMake LSPs have aneurysms when you put the end parenthesis on a
  different line. Annoying? Yes, but this is all we can really do about
  it for now.
- `set`, `option`, and `message` should not have spaces before their
  opening parenthesis.

crueter f2a1243892 [cmake] use MINGW builtin rather than custom detection
CMake has had the `MINGW` builtin to describe MinGW targets since at
least version 3.2, so it can safely be used. This variable is also set
for the MSYS2 environments, so CLANGARM64 also correctly sets `MINGW`.

Note that this depends on https://github.com/FEX-Emu/jemalloc/pull/11.

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.

This also requires us to scan both data directories and config
