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).
`DetermineVASize` does not return the size of VA, but the number of bits
it can use. Change the naming to make it more self explanatory.
In the mean time also move `HostVASize` global into `GetHostVABits`
since it is not and should not be used directly.
Commit abf9724 ("Allocator: Fix and optimize VA range detection")
removed assignment to the `HostVASize` global thus making each call to
`DetermineVASize` redo all the work with potential to produce incorrect
results. Set the global again to fix this.
While unlikely to be used in practice over other kind of
shuffling and blending, these should also have stress tests
to make sure they do the right thing.
Currently we split these into two 128-bit operations since VIXL doesn't
have support for the unified SVE operations yet.
Now we fully support VAES on SVE256.
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.
We really don't want to do this, but in the case that the AF_UNIX path
is longer than the 108-byte limit that sun_path provides we don't really
have a choice. The alternative choice would be to switch /entirely/ away
from AF_UNIX and instead use pipes. We need a bandage fix for now, so
throw the socket in to a temp folder if the path is too long.
CPUFeature detection is marginally different between Linux and Windows.
FOC was only using the Linux path which had two broken things happening
to it.
- Feature detection was incorrect and enabling/disabling features
differently from wow64/arm64ec .dll files
- HostType was being set as Linux even though it was generating code for
WINE
Ensure that when built for Win32 that it uses the correct feature
fetching.
One thing that is still incorrect is that 64-bit or 32-bit is determined
at compile time on win32, whereas the Linux side parses an ELF and
determines bitness at runtime. This doesn't fix that remaining problem
there.
