cuda - How to disable a specific nvcc compiler warnings

Question

I want to disable a specific compiler warning with nvcc, specifically

warning: NULL reference is not allowed

The code I am working on uses NULL references are part of SFINAE, so they can't be avoided.

An ideal solution would be a #pragma in just the source file where we want to disable the warnings, but a compiler flag would also be fine, if one exists to turn off only the warning in question.

Answer 1

It is actually possible to disable specific warnings on the device with NVCC. It took me ages to figure out how to do it.

You need to use the -Xcudafe flag combined with a token listed on this page. For example, to disable the "controlling expression is constant" warning, pass the following to NVCC:

-Xcudafe "--diag_suppress=boolean_controlling_expr_is_constant"

For other warnings, see the above link.
