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.
Serializes code blocks to disk - only blocks coming from known regions, for now
Disabled by default, key and versioning still needs work, but works for testing
This fixes compilation with libc++ 23, which has removed a number
of unnecessary transitive includes in its headers.
Include <cstdlib> in StringConv.h for std::strtoll and std::strtoull.
Include <cstdlib> for the declarations of malloc/free/realloc/calloc
in Alloc.cpp. (Without this, the functions we define end up with
C++ name mangling.)
Include <stdarg.h> in IO.cpp for va_start/va_end.
This just means the end of the file is being used as the base offset.
Also note that according to the documentation for SetFilePositionEx,
that setting the position beyond the current file size is not considered
an error as far as the API is concerned.
The lazy code loading refactor replaced LoadData with the new
LoadCache/EnableLoadedSection API but left the Windows path as TODOs.
Implement the wiring: LoadAOTImages now calls LoadCache +
RegisterMappedCodeBuffer for each mapped cache file, and HandleImageMap
calls EnableLoadedSection (with nullptr thread since lazy mapping is not
yet implemented on Windows).
This was accidentally setting `CurrentSize` instead of just returning
the newly allocated size to the frontend. This was causing the frontend
to then fail to detect the reallocation actually occured and no longer
get stats for new threads.
Also happened to not use `NewSize` but instead `CurrentSize * 2` which
didn't matter as it matched the growth pattern, but was technically
incorrect.
Fixes SHM stats since the introduction of the unixlib, ezpz.
Centralizes all the nasty behaviour that will end up breaking when WINE
eventually turns on userspace syscall dispatch. Pushes all of the logic
in to the UnixLib. Support both paths until everyone is migrated to
supporting the UnixLib, then we can delete the bit of code duplication
between the PE side and UnixLib side.
Helpful that everything that gets punched through the UnixLib is
optional, so worst case some optional bits can break for a while.
This was handled in both the Module.cpp files and also the common
TSOHandlerConfig on accident. Wouldn't have caused an issue but it was
definitely a bit weird.
Including fallback to non-unixlib path because we need to support both.
Showcases how these are going to be implemented without throwing the
entire world at it right away. Next PR will be implementing the
remaining four necessary unixlib handlers that we will require:
- Kernel unaligned atomic control
- shm_stats thing
- madvise operation
- prctl vma naming
Currently does nothing other than load it (as the library also doesn't
do anything yet). Ensured it was working by temporarily creating a test
entrypoint and doing `Call` on to it.
Next step after this is to reimplement some of the nasty hacks FEX is
doing inside the unixlib code itself.
Because these compile options change codegen, we need to make sure these
are runtime selected rather than compile-time selected. Will reduce
code-cache variance.
We were accidentally allocating some things without this flag and it was
causing us to dump memory in to the lower 32-bits on arm64ec.
This was causing the game
[Below](https://store.steampowered.com/app/250680/BELOW/) to run out of
memory to allocate for its LUA JIT and causes it to crash.
To not have this environment variable accidently be enabled on arm64
native Wine games, we need to set it from inside of FEX.
Requires the FEX dlls to set them directly rather than launch scripts.
