      constexpr construction for Vec classes · 94749655
      Shreeraj Jadhav authored
      Vec class objects can now be constructed during compile-time
      as constant expressions by calling Vec( T, ... ) constructors
      or through brace-initialization.
      Constant expression using fill constructor and nested vectors
      of sizes greater than 4 are not supported yet.
      Changes made to WrappedOperators.h for resolving overload
      ambiguities in Vec construction and typecasting.
      Appropriate test cases were added to UnitTestTypes.cxx.
      Addresses issue #199.

      Enable Vec construction with intializer_list of single value · 15789443
      Kenneth Moreland authored
      Previously, the initilaizer_list of Vec had to be the exact
      same number of values as the size of the Vec. Now, we also
      accept a single value that is duplicated for all values in
      the Vec. That allows you to more easily construct lists
      of lists with repeated values.

      Add support for initializer lists in Vec · ae8d994d
      Kenneth Moreland authored
      Add constructors to the `vtkm::Vec` classes that accept
      `std::initializer_list`. The main advantage of this addition is that it
      makes it much easier to initialize `Vec`s of arbitrary length.

      VTK-m Vec<> constructors are now more conservative. · adcabb03
      Robert Maynard authored
      When you have a Vec<Vec<float,3>> it was possible to incorrectly correct
      it with the contents of a Vec<double,3>. An example of this is:
      using Vec3d = vtkm::Vec<double, 3>;
      using Vec3f = vtkm::Vec<float, 3>;
      using Vec3x3f = vtkm::Vec<Vec3f, 3>;
      Vec3d x(0.0, 1.0, 2.0);
      Vec3x3f b(x); // becomes [[0,0,0],[1,1,1],[2,2,2]]
      Vec3x3f c(x, x, x); // becomes [[0,1,2],[0,1,2],[0,1,2]]
      Vec3x3f d(Vec3f(0.0f,1.0f,2.0f)) //becomes [[0,0,0],[1,1,1],[2,2,2]]
      So the solution we have chosen is to disallow the construction of objects such
      as b. This still allows the free implicit cast to go from double to float.
      So while `Vec3x3 b = x is supported by vtk-m, it produces very incorrect results.

      Ensure that Pair and Vec are trivial classes. · 4cd79193
      Allison Vacanti authored
      For std::copy to optimize a copy to memcpy, the valuetype must be both
      trivially constructable and trivially copyable.
      The new copy benchmarks highlighted an issue that std::copy'ing pairs
      and vecs were not optimized to memcpy. For a 256 MiB buffer on my
      laptop w/ GCC, the serial copy speeds were:
      UInt8:                 10.10 GiB/s
      Vec<UInt8, 2>           3.12 GiB/s
      Pair<UInt32, Float32>   6.92 GiB/s
      After this patch, the optimization occurs and a bitwise copy occurs:
      UInt8:                 10.12 GiB/s
      Vec<UInt8, 2>           9.66 GiB/s
      Pair<UInt32, Float32>   9.88 GiB/s
      Check were also added to the Vec and Pair unit tests to ensure that
      this classes continue to be trivial.
      The ArrayHandleSwizzle test was refactored a bit to eliminate a new
      'possibly uninitialized memory' warning introduced with the default
      Vec ctors.

      Fix warnings about assignment operators not being generated · f23ff9fa
      Kenneth Moreland authored
      For some reason when VTK-m was being compiled as an accelerator in VTK,
      Visual Studio 2013 gave a bunch of warnings about not being able to generate
      assignment operators for many classes. This happened for classes with a
      const ivar that could not be automatically set. (Automatic copy constructors
      are fine on this count.) I'm not sure why these warnings did not happen
      when just compiling VTK-m, nor am I sure why they were generated at all as
      no code actually used the copy constructors.
      This commit fixes the problems by adding a private declaration for assignment
      operators that cannot be automatically created. No implementation is
      provided, nor should any be needed.

      Types and Matrix don't emit Wunused-value warnings from __builtin_expect · 270ece24
      Robert Maynard authored
      When using Types or Matrix with the nvcc compiler with Wunused-value
      enabled you would get the following warning:
      (__builtin_expect(!(rowIndex < (this,NUM_ROWS)), 0)) ?
      __assert_rtn(__func__, "vtkm/Matrix.h", 86, "rowIndex < this->NUM_ROWS") :
      This is solved by changing this->NUM_ROWS to just NUM_ROWS.

      Add VTKM_EXEC_CONT to make_VecC · eb7ea792
      Kenneth Moreland authored
      I forgot to add the VTKM_EXEC_CONT modifier to the make_VecC methods,
      and that causes them to fail on CUDA devices.
      I wish the compiler would have said something. I was calling one of them
      from a VTKM_EXEC method.

      Add VecC and VecCConst structs · f53cd748
      Kenneth Moreland authored
      These structs behave much like Vec except that they work on a short C
      array given to them rather than having the statically sized short array
      defined within.
      I expect to use this in the short term to help implement cell face
      classes, but there are probably many other uses.

      Add POSIX assert wrapper · 2ddad8bc
      Kenneth Moreland authored
      Add in the vtkm namespace an assert macro (technically VTKM_ASSERT) that
      basically replicates the functionality of the POSIX assert macro. This
      form of assert is set to replace the separate control/exection asserts.
      It has been decided that an assert that throws an exception instead of
      terminating the program is not all that great of a feature and it causes
      some limitations on how it is used. The next commit will remove the
      other forms of VTK-m assert.
