CUDA: NVCC gives controlling expression is constant warning on assert

Question

I get the warning controlling expression is constant on assert statement like this:

assert(... && \"error message\");

Answer 1

If it is LLVM based, then you can use something like this:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wmultichar"

char b = 'df'; // no warning.

#pragma clang diagnostic pop

From Controlling Diagnostics via Pragmas.
