This is a fancy array that takes an array of offsets and converts it to
an array of the number of components for each packed entry.
This replaces the use of `ArrayHandleDecorator` in `CellSetExplicit`.
The two implementation should do the same thing, but the new
`ArrayHandleOffsetsToNumComponents` should be less complex for
compilers.
Reduces the amount of code that has to be generated. Also improves the
number of arrays supported and has better support for deprecated
versions of `GetRange`.
CUDA architecture has a limited amount of memory available for
constants. The CUDA compiler uses this space to hold constants for some
optimizations. However, for large kernels, the number of constants
needed might be larger than the constant space available. For these
conditions, you have to disable this form of optimization with the `-
Xptxas --disable-optimizer-constants` flags.
Currently, the only file that seems to have this issue is the test for
the Lagrangian filter. Someone should take a closer look to see if this
filter in particular is making unnecessarily large worklet/kernel. (In
particular, why does the Lagrangian filter have a larger kernel than the
streamline and stream surface filters?)
If this occurance happens more often, we might need to add some ways to
configure it in the build.
There was some compile errors with CUDA and the CellLocatorGeneral.
Apparently it added enough to the CUDA kernel to cause issues with
constant memory.
`CellLocatorChooser` allows you to select a cell locator at compile
time. Unlike `CellLocatorGeneral`, you have to deduce what cell set
types you might have, but you don't have to have a large switch
statement in the middle of your worklet.
There appears to be a bug in GCC where if you mixed C++ attributes like
`[[deprecated]]` with GNU attributes like `__attribute__(())`, you will
get a compile error. This can be a problem when using attributes to both
set the export (i.e. visibility) of an item and deprecating the same
item.
This problem has been encountered before. Commit
34b0bba84207a89e8fddfe62e7a1ff30b1b53a18 fixed the problem by using
`[[gnu::visibility()]]` instead of `__attribute__()` in the export
macros. This works fine for export macros defined by VTK-m headers such
as `VTKM_ALWAYS_EXPORT`. Unfortunately, we have little control over the
export macros that CMake automatically creates. Rather than rewrite the
CMake export code, we go the other way and use `__attribute__()` for all
exports _and_ the depreciated attribute.
Deprecated the `CellLocator` class and made all methods of the
other `CellLocator` classes non-virtual. General locators can
still use the `CellLocatorGeneral` class, but this class now
only works with a predefined set of locators. (The functionality
to provide a function to select a locator has been removed.)

With recent changes to `Arrayhandle`, the type for the associated array
portal is now the same across all devices. This means that almost all
exec objects no longer need to be specialized on the device types. Thus,
clean up the whole array exec objects to no longer need to be templated
on device.
The original `ArrayHandle` design had the `PrepareFor*` methods
templated on the device adapter tag. This is no longer necessary (at
least for any existing `ArrayHandle`), so support calling `PrepareFor*`
with a `DeviceAdapterId` that is resolved at runtime.
With recent changes to `ArrayHandle`, the type for the associated array
portal is now the same across all devices. This means that almost all
exec objects no longer need to be specialized on the device types. Thus,
clean up the locator exec objects to no longer need to be templated on
device.

One of the MSVC builds was giving template resolution problems for one
of the methods declared non-inline for no discernable reason. It sounds
like a compiler bug. Rather than try to work around the issue, just
move the declaration inline.
In fact, all the methods are really small (only 1 or 2 lines). Just
delete the .hxx file and simplify things.
The `GetMaxNumberOfNeighbours` of the `MeshStructure*` classes was
declared `constexpr`. This was causing some compiler errors.
I think the problem is actually a bug with GCC (https://gcc.gnu.org/
bugzilla/show_bug.cgi?id=66297). Whether it is a compiler bug or not,
there does not seem to be a large value to declaring this method
`constexpr`, so I just removed the keyword.
Somewhere during this edit I removed a header file that didn't strictly
need to be there. This caused me to have to add
```cpp
```
in several places in the code.
The newer version of `ArrayHandle` no longer supports different types of
portals for different devices. Thus, the `ReadPortalType` and
`WritePortalType` are sufficient for all types of portals across all
devices.
This significantly simplifies supporting execution objects on devices,
and thus this change also includes many changes to various execution
objects to remove their dependence on the device adapter tag.
Some (but not all) versions of visual studio seem to have a bug that
causes a syntax error when using the deprecated attribute in a templated
constructor.
The actual code for AtomicArrayExecutionObject does not need to be
specialized by the device. The functionality is implemented by calling
the vtkm::Atomic* methods, which are properly implemented on each
device.
Unfortunately, there is no way to specify when copying `RecombineVec`s
whether we wish to allow precision loss in conversions. Because
sometimes we need them, disable the warnings.
It used to be the case where you needed to call `ResetTypes` on a
`VariantArrayHandle` before using `ArrayCopy` to limit the types it gets
compiled for. However, there is now a general form for
`UnknownArrayHandle`, so `ResetTypes` no longer does anything useful in
this case. Remove the use of that.
Rather than copy every type to every other type, only copy for the same
base type or copy to/from FloatDefault. This should reduce the amount of
code generated by a lot.
This reduces the size of the .o for ArrayCopy.cxx on my mac from
21MB to 7.7MB.
Add an overload of `ArrayCopy` that takes `UnknownArrayHandle`s and
copies them for (almost) any `ArrayHandle` type.
The code uses `CastAndCallWithExtractedArray` to reduce the total number
of copy conditions to about 100, which are all precompiled into the
library. On a debug build on my mac, this creates a .o file of 21MB.
That's not great, but not terrible. Hopefully, this can be used to
consolidate copy implementations elsewhere.
