The ability to write kernels is limited to LDC, though there
is no practical reason that, once compiled, you couldn't use
resulting generated files with GDC or DMD (as long as the
mangling matches, which it should). This is not a priority to
get working, since the assumption is if you're trying to use
the GPU to boost your computing power, then you like care
enough to use LDC, as opposed to DMD (GDC is still a bit
behind DMD so I don't consider it) to get good optimisations
in the first place.
Yes, but dmd is still good for development since LDC sometimes
has problems.
If you have problems please tell us!
Can we compile kernels in LDC and import them in to a D project
seamlessly? Basically keep an LDC project that deals with the
kernels while using dmd for the bulk of the program. I mean, is
it a simple import/export type of issue?
Yes, although I'll have to add an attribute shim layer for the
dcompute druntime symbols to be accessible for DMD. When you
compile LDC will produce .ptx and .spv files in the object file
directory which will be able to be used in any project. The only
thing that will be more fragile is lambda kernels as they are
mangled numerically (`__lambda1`, `__lambda1` and so on).
