Cedric Nugteren 4a5516aa78 Added extra error codes to reflect the more detailed error reporting of OpenCL functions 2016-10-22 15:46:29 +02:00
Ivan Shapovalov 56f300607b Routine: get rid of ::SetUp() 
Since we now use C++ exceptions inside the implementation (and exceptions
can be thrown from constructors), there is no need for a separate
Routine::SetUp() function.

For this, we also change the way how the kernel source string is constructed.
The kernel-specific source code is now passed to the Routine ctor via
an initializer_list of C strings to avoid unnecessary data copying
while also working around C1091 of MSVC 2013.

Ivan Shapovalov b98af44fcf treewide: use C++ exceptions properly 
Since the codebase is designed around proper C++ idioms such as RAII, it
makes sense to only use C++ exceptions internally instead of mixing
exceptions and error codes. The exceptions are now caught at top level
to preserve compatibility with the existing error code-based API.

Note that we deliberately do not catch C++ runtime errors (such as
`std::bad_alloc`) nor logic errors (aka failed assertions) because no
actual handling can ever happen for such errors.

However, in the C interface we do catch _all_ exceptions (...) and
convert them into a wild-card error code.
