hi, everyone.
i'm newbie on opencl development. when i try to create an opencl kernel program from source.
i got this error:
error: undefined reference to `__builtin_spirv_OpenCL_ctz_i128'
how can i fix it? it seems a spir-v built in function. but i'm sure i did NOT use it in my code.
thanks.
my platform info as follow (from clinfo):
