Using clang-3.8, I need the attached patch in order to compile beignet.
Otherwise I get lots of errors that look like:
/home/andrew/Downloads/beignet-intel_subgroups/utests/builtin_exp.cpp:18:48:
error:
non-constant-expression cannot be narrowed from type 'double' to
'float' in initializer list
[-Wc++11-narrowing]
const float input_data[] = {FLT_MAX, -FLT_MAX, FLT_MIN, -FLT_MIN, 80, -80,
3.14, -3.14, -0.5, 0.5, ...
