There exists some kind of push/pop but I'm not sure it is relevant is
your context nor that llvm/clang support them.
In one of my projects where I include a header file that produces
warnings (with #warning ...) and that adds the "deprecated" attribute
to some function, I use:
#pragma GCC diagnostic push
# pragma GCC diagnostic ignored "-Wcpp"
# define CL_USE_DEPRECATED_OPENCL_1_1_APIS
# include <CL/cl.h>
#pragma GCC diagnostic pop
#pragma GCC diagnostic ignored "-Wdeprecated-declarations"
Note that the "-Wdeprecated-declarations" is not in the push/pop
section because it needs to be active at the time that deprecated
functions are used, not at the time that deprecated functions are
declared with their attribute (ie in <CL/cl.h>)
