See the comment added by this commit. We were previously guarding against
overshooting in address calculations, but not against undershooting.
Perhaps someone assumed that the displacement of an x86 loadstore was
treated as unsigned?
Note: While the comment says we can undershoot by up to 2 GiB, in
practice Jit64 as it currently behaves won't actually undershoot by more
than 0x8000 if my analysis is correct. But address space is cheap, so
let's guard the full 2 GiB.
This generated a warning on GCC about the operation being potentially undefined (-Wsequence-point). I'm not sure if that was actually the case, but either way it is a mistake.
When using a fullscreen mode on some phones that remove the navigation bar, inset callbacks will not be fired. To account for this we set the workaround view at a height of 1px to prevent the view from filling the entire screen due to this activity using a Constraint layout.
Before, it was also compiled on ARM builds, but since it was unused it wasn't linked (and thus its dependency on the nonexistent x64Emitter didn't cause any link issues).
For some reason, when this is included, the linking step creates a temporary file in %TEMP% with a random name; the file is deleted afterwards and a new random name is used on a later build. Because this file doesn't exist on a later build, curl gets re-linked each time, and then all of the projects that depend on curl also get re-linked. This adds around 10 seconds to the build time even for small changes.
To make things worse, I don't think libcurl.rc does anything useful since we statically link curl; I believe the metadata contained in it only applies when building a dll. (It does seem to be included in curl.lib, but gets discarded when linking Dolphin.exe.)
See Build\x64\Release\curl\curl.tlog\Lib-link-cvtres.write.1.tlog for the log that shows this path (the file is also mentioned after setting Tools -> Options... -> Projects and Solutions -> Build and Run -> MSBuild project build output verbosity to diagnostic, but not in a useful way).
