The change in commit v3.9.0-rc4~3^2 (VS: Improve workaround for CUDA
-Xcompiler placement bug, 2017-06-21) accidentally appended to the
`AdditionalOptions` as if it were a `;`-separated list, but it is
actually a command-line string. Append with a space instead.
While at it, fix the same problem for the `AdditionalOptions` added to
`CudaLink` by commit v3.9.0-rc3~1^2 (CUDA: When linking device code
suppress CUDA 8.0+ deprecation warnings, 2017-06-09).
Fixes: #17008
In commit v3.9.0-rc1~431^2~6 (VS: Place CUDA host compiler options in
proper project file fields, 2017-03-07) we worked around a bug in the
CUDA VS integration by dropping `AdditionalCompilerOptions`. However,
this silently drops `-Xcompiler=` options given by the user that don't
map to one of CudaCompile's dedicated settings. Improve the workaround
to instead put the remaining `AdditionalCompilerOptions` into the
`AdditionalOptions` field behind `-Xcompiler=` ourselves.
Fix the VS generator to honor `COMPILE_OPTIONS` for CUDA. The exclusion
added by commit v3.9.0-rc1~431^2~7 (VS: Do not pass CUDA compile options
to C compiler, 2017-03-07) was correct but we need additional logic to
pass the CUDA compile options to the CUDA compiler. Also we should
still pass the CXX or C options to MSVC (ClCompile) when those languages
are enabled even if the link language is CUDA.
If a static library has the property CUDA_RESOLVE_DEVICE_SYMBOLS enabled
it will now perform the device link step. The normal behavior is
to delay calling device link until the static library is consumed by
a shared library or an executable.
CUDA 8.0 MSBuild rules do not pass `-x cu` to nvcc and so cannot support
a custom file extension. Fix our test for this to use a `.cu` extension
instead.
Add `.clang-format` configuration files for Cuda test directories that
use `Standard: Cpp11`. Otherwise clang-format splits the triple angle
brackets used for CUDA kernels.
