For now, a simple directory structure with filename based mapping is
used:
LOCALAPPDATA/cache/<main image id>/{<dll 1 image id>, <dll 2 image id>}
All cache blobs are loaded once at the start for simplicity, this will
also be useful in the future as metadata validation for settings etc can
be done just once.
I may have gotten carried away.
- I missed some stuff for end parenthesis because I accidentally
searched within project files instead of the entire directory (so some
thunk/test/windows stuff was missed), cleaned those up.
- `INTERFACE`, `PUBLIC`, `PRIVATE`, `RUNTIME`, `LIBRARY` should be on
the same line as the target name. (I should really invest in making a
style guide...)
- Some short statements were unnecessarily split across multiple
lines--cleaned those up
- Made a common `LinkerGC` module that applies gc-sections etc. to a
target in Release mode
- Usually for functions you want to have something on the first line,
e.g. `FILES`/`DIRECTORY` for install, or the target/a positional
argument, etc etc. Not always though, notably for some custom_command
calls
TODO:
- What's with the `list(APPEND LIBS...)` stuff? It's used really
inconsistently, sometimes not at all, sometimes it looks like there're
duplicates? A more thorough cleanup is in order there.

- Do compiler/architecture checks EARLY, don't waste time doing random
configuration stuff if the user can't even compile in the first place
- MSVC is unsupported, I assume? So add a check to disallow. There's
literally no MSVC or MSC_VER checks anywhere, so...
- Rather than using the MSVC architecture definitions, use our own
`ARCHITECTURE_arm64` et al. Hijacking existing "standard" definitions
is a very bad idea. Also makes it more readable in CMake
- Change the x86 host check to `x86|amd64`. Some systems still refer to
themselves as x86 despite being 64-bit for... reasons, and I saw one a
very long time ago that referred to it as amd64. This should
basically never come up, nor is it really relevant given that FEX is
for arm64... but it kinda annoyed me so whatever.
TODOs:
- Should we check `CMAKE_SIZEOF_VOID_P (equal) 64`? I don't think anyone
is even trying to compile this thing on armv7 or older, but might as
well? maybe?
- What's the status of *BSD, Solaris, macOS? Technically macOS does
support Wine, not sure about the others.

and use it to commonise volatile metadata code (adding WOW64 image
voltmd support in the process). This will be extended to track mapped
images for code caching.
Default to enabled because this is the config we expect by default.
In the future will get some benchmarking in various games like
Assassin's Creed, and Call of Duty.
When the JIT CodeBuffer overflows, we will now catch accesses to the
guard page and longjump while restarting the JIT with a larger buffer
request.
Fixes#4877
This reverts commit e1a45a2720, reversing
changes made to bd7edd8651.
The change rendered pressure-vessel non-functional on muvm-based setups
like Fedora Asahi Remix.
rpmalloc is currently very aggressively configured which causes
significant reductions in resident memory over jemalloc.
In Bayonetta's title screen it went from 963MB down to 834MB resident.
This mode has been broken for a long time because it's mostly untested.
Barriers, and backpatching while slow have proven that they work.
Maintain the one TSO path, at least until all ARM hardware gains support for
x86-TSO memory model mode.
Only wired up for wow64 and arm64ec. Gives more granular control over
TSO enabling and disabling. Matches arm64ec volatile metadata except
with one more additional feature that whole modules can be disabled at a
time.
Once we know the mapped size of files in Linux then we'll be able to do
the same thing there, but there's not a full mechanism wired up for that
yet.
While most applications will just create ALL_ACCESS handles which
support the additional operations FEX needs over the regular windows syscall
(usually just QUERY_INFORMATION to lookup the thread object), it is
valid for them to pass in the minimal set required for each operation
and windows/wine will reject any other operations (e.g. querying the TEB
base on a handle with only the SUSPEND right). Windows permits
duplicating handles to extend their permissions given the process itself
has such permissions, so do that as necessary for the operations FEX
needs.
In the terminate case, if we don't return early then we will delete the
FEX thread object but the actual terminate call that follows will
fail, leaving the thread in a bad state.
Allocate the stack with uncommited guard pages on either side, if
any faulting accesses to these occur then the call-ret SP value is
reset to the default and execution resumed.
