In trying to give error diagnostics with template definitions of invalid
types, the user encounters some pretty confusing error messages at
first. There is no way to get the compiler to give exactly the
diagnostics we want in a nice readable error message, so we are putting
some verbose instructions as comments in the code. However, a user might
not know to look at the source code since the error happens deep in an
unfamiliar (and complicated) class. Thus, add (yet another) error at the
front that gives a (hopefully) clear indication to look at the source
code for help in understanding the errors.
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.
For some reason on my Visual Studio 2013 the definition of
VTKM_STATIC_ASSERT (without the message) did not report where the actual
error message happened. This change seems to get Visual Studio to report
the location of the failed assert with a reasonable message.
The current CUDA compiler is crashing when using _Pragma in code blocks,
which were being used with clang on apple. Turn these off when compiling
with CUDA.
This is to be used in place of BOOST_STATIC_ASSERT so that we can
control its implementation.
The implementation is designed to fix the issue where the latest XCode
clang compiler gives a warning about a unused typedefs when the boost
static assert is used within a function. (This warning also happens when
using the C++11 static_assert keyword.) You can suppress this warning
with _Pragma commands, but _Pragma commands inside a block is not
supported in GCC. The implementation of VTKM_STATIC_ASSERT handles all
current cases.
