The current way we handle cl_khr_fp64 and cl_khr_int64 leads to much
code duplication. One alternative would be to define two macros
__IFDBL(x)
__IFLNG(x)
that expand to their arguments if double and long are supported,
respectively, and expand to nothing otherwise.
#ifdef cl_khr_fp64
# define __IFDBL(x) x
#else
# define __IFDBL(x)
#endif
We would surround every line in _kernel.h that uses double or long
with the respective macro. This would look like
#define _CL_DECLARE_FUNC_V_V(NAME) \
float _cl_overloadable NAME(float ); \
float2 _cl_overloadable NAME(float2 ); \
__IFDBL(double _cl_overloadable NAME(double );) \
__IFDBL(double2 _cl_overloadable NAME(double2 );)
Does this sound like a good idea?
