There was an error in `operator-=` for `IteratorFromArrayPortal` that went
by unnoticed. The operator is fixed and regression tests for the operators
has been added.
The ArrayPortalWrapper is used for both execution and control portals.
When it was wrapped around a control portal that does not work on CUDA
devices, we were getting ugly warnings even though the intention was
only to use it in the control environment.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
This is a fancy array handle that can group entries in another array by
arbitrary amounts. This allows us to implement input and output arrays
with a different sized Vec for each instance. This is necessary for
generating new topologies with cells of different types.
Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and
EXEC_CONT.) Remove the inline from these macros so that they can be
applied to everything, including implementations in a library.
Because inline is not declared in these modifies, you have to add the
keyword to functions and methods where the implementation is not inlined
in the class.
I don't know why, but under some circumstances when compiling with CUDA
and Visual Studio, the compiler was giving syntax errors when the
IteratorFromArrayPortal was using the typename keyword to reference a
type in its superclass. Get around the problem by looking directly in
the superclass.
These asserts are consolidated into the unified Assert.h. Also made some
minor edits to add asserts where appropriate and a little bit of
reconfiguring as found.
My version of the PGI compiler was having problems with using
IteratorFromArrayPortal with STL algorithms. I traced the problem to
iterator_facade checking to see if the reference type we gave it was
a real reference (e.g. T&). It is not, iterator_facade downgraded the
iterator trait to a simple input iterator tag even though I declared
it with a random access traversal. I don't know what the reference type
has to do with random access, but in any case the value object is
designed to behave like a reference in that when you assign to it
the value gets propagated to the array. To tell boost this is the case,
I made a specialization of boost::is_reference that declares the
value type as a reference.
I'm not sure why it failed for me but not elsewhere. It might be that
this version of the PGI compiler is using "old-style" iterator traits
whereas other were using newer style that matches better the boost
iterator traits that iterator_facade is actually using.
On one of my compile platforms, GCC was giving conversion warnings from
any boost include that was not wrapped in pragmas to disable conversion
warnings. To make things easier and more robust, I created a pair of
macros, VTKM_BOOST_PRE_INCLUDE and VTKM_BOOST_POST_INCLUDE, that should
be wrapped around any #include of a boost header file.
Previously, IteratorFromArrayPortal was declaring its difference_type
to be vtkm::Id. Although this is allowed, there is code that assumes
that iterators have a difference_type that is ptrdiff_t or something
similar. This change makes the difference_type the default for the
boost iterator facade, which should be the type other code that\
neglects to check expects.
In preparation for supporting base types with more widths, add typedefs
for the base types with explicit widths (number of bits).
Also added a IdComponent type that should be used for indices for
components into tuples and vectors. There now should be no reason to use
"int" inside of VTK-m code (especially for indexing). This change cleans
up many of the int types that were used throughout.
We made this change a while ago to help with completion in IDEs.
(Completion was matching a bunch of wrapper macros that were almost
never used anywhere.) Most of the changes are in comments, but there are
a few bad macro definitions.
