src/kat/on_device/unaligned.cuh <- Dropped from the repository (but expected to make a comeback soon - with unit tests)
src/kat/on_device/grid_info.cuh <- These are all one-liners; it's like testing an int add(int x, int y) { return x+y; } function - what can you test about it?
src/kat/on_device/printing.cuh <- Dropped from the repository (for now)
src/kat/on_device/ptx/* <- Mostly covered by "builtins" unit tests, and not quite "user-facing".
Most code in the library is currently not covered by any unit tests. Let's add that coverage.
Skipping:
int add(int x, int y) { return x+y; }
function - what can you test about it?
