These had completely forgotten to load segment prefixes on the element
loadstore operations. This had caused a crash on the Linux version of
"Halls of Tormet" (steamid 2218750).
This game has TLS vector data which it was loading with a movhps and hit
this path.
fixes incorrect signs on FPREM. in turn should fix end-to-end failures logging
into Steam.
Thank you to Sergio Lopez for tracking down the JavaScript fail, and Ryan for
finding the bug.

This is an interesting vdso implementation because it only exists in
x86-64 with kernel v6.11. For Arm64 the implementation is likely to land
in a couple kernel versions from now.
Some differences with vdso_getrandom versus the regular getrandom
syscall
- Has two additional arguments, opaque_state and opaque_len
- Expects the userspace to mmap/munmap this opaque state structure
- Lets userspace query information about this structure upfront
- If the opaque data structure isn't provided then it falls back to
regular SYS_getrandom
With the "glibc" implementation, we can tell the interface to allocate a
single page that gets unused (otherwise glibc ends up not using the
interface), and fallback to the regular SYS_getrandom.
In the case of the vdso interface, currently the arguments just get
passed through.
Keeping this as a WIP until the ARM64 kernel patches land and I can
actually test the things. Running the "glibc" path works today with the
selftest, but the vdso path is currently completely untested.
Between this version and our previous version v1.3.278 this adds a few
extensions.
- VK_EXT_device_generated_commands
- VK_EXT_depth_clamp_control
- VK_AMD_anti_lag
- VK_KHR_pipeline_binary
These extensions are almost immediately getting picked up by mesa and
the D3D layers, so we want to support them as soon as possible.
Once again updated as described in #2076. This is starting to take more
time as more features and extensions get added to Vulkan. We probably
want to update the `DefinitionExtract.py` script at some point to
contain all the tertiary data in some json so everything gets generated
automatically. Not doing that today but something to think about.
Fixes#4083
From prep commit 511103ee5dcc9474b0b7468c05f61ce10fea4393.
Now that the frontend is setup, we can remove the temporary TLS
variables and use the ThreadObject directly.
Moves from FEXCore to FEX::HLE. Also moves the ThunkFunctions that get
exposed to a namespace to make it more obvious that these are
thunkhandlers rather than just static functions.
With the new systemd support, we had forgotten to wrap this check in an
arm64 check. I had done an install and broke my x86 machine.
Add the check back so we stop breaking x86 machines...again. Took me
only about three hours to find the issue this time.
Global rootfs doesn't support a named rootfs (only local supports that).
So when it is a global rootfs option just give the full path to the
config path.
Just needs some special handling to ensure the full path is retained for
global paths.
A reimplementation of #4067 that doesn't hardcode paths and routes the
global data path through FEXCore.
Using select initially was a mistake, it has issues with FD limits and
is less efficient due to fd_set. It's recommended to switch select using
over to polling, so do it.
