[PATCH] D63164: [HIP] Add option to force lambda nameing following ODR in HIP/CUDA.

[Artem Belevich via Phabricator via cfe-commits]

tra added a comment.

So, in short, what you're saying is that lambda type may leak into the mangled name of a `__global__` function and ne need to ensure that the mangled name is identical for both host and device, hence the need for consistent naming of lambdas.

If that's the case, shouldn't it be enabled for CUDA/HIP by default? While it's not frequently used ATM, it is something we do want to work correctly all the time. The failure to do so results in weird runtime failures that would be hard to debug for end-users.

@rsmith -- are there any downsides having this enabled all the time?
