Input/output tracking is intended to speed up incremental builds by
skipping a target when it doesn't need to be built. However, this seems
to be unreliable for UnitTests' AfterBuild target. Let's remove it.
It's still the case that UnitTests' AfterBuild target will be skipped if
UnitTests doesn't need to be rebuilt. (Note that UnitTests always needs
to be rebuilt if SCMRevGen changed.)
I haven't seen these problems with DolphinQt's rather similar
input/output tracking. This may be because DolphinQt's one also has the
exe file as an input/output.
`std::bit_cast` participates in overload resolution only if `sizeof(To) == sizeof(From)` and both `To` and `From` are *TriviallyCopyable* types, so the static assertions here can be removed. `[[nodiscard]]` was added as well.
Like the previous commit, but for UnitTests. This time all operating
systems were affected.
I also made UnitTests.vcxproj use the same way of copying as
DolphinQt.vcxproj, just for consistency.
For a long time now, we've had a problem where game INIs persist in
the copied Sys folder if they've been deleted from the original Sys
folder. (I still have hundreds of game INIs locally that only set
EmulationStateId, and we removed those game INIs 6 years ago. On the
buildbot, we do occasionally clear out the build directories manually,
so I'd assume it's not quite as bad there.)
This commit fixes the problem by deleting the output Sys folder before
copying the original Sys folder to the output Sys folder. This should be
a bit slower, but in my testing, the difference seems small. At least if
you have an SSD, which I really hope people have nowadays!
Operating systems other than Windows have not been touched, because:
* Android: Already explicitly deletes the output Sys folder.
* macOS: Does some magic to put the Sys folder in the app bundle, which I
will simply assume isn't affected by this problem, without testing.
* Linux: Expects the person building to manually manage the Sys folder.
Update the checkmarked slot in the Select State Slot menu when the
Increase Selected State Slot or Decrease Selected State Slot hotkeys are
pressed.
The actual selected save slot was being changed correctly before this
commit; this just fixes the menu checkmark.
