    llvm-project/flang/include/flang/Optimizer/Support/Utils.h:131: not yet implemented: intrinsic: REAL(KIND=2) in SPACING

It seems it's not REAL(KIND=2), but the implementation for that type in the SPACING intrinsic.  Looking at flang/lib/Optimizer/Builder/Runtime/Numeric.cpp, it appears that SPACING, and several other intrinsics, are implemented for larger float types. 

Compiling kind_find ( https://github.com/srinathv/Coding-Examples/blob/master/codingTests/fortran90/kindfind.f90) with flang suggests that REAL(KIND=2) is at least nominally implemented.

Flang gives a sensible error message, but hoping to get this on someone's radar as much software depends on HDF5.

Thanks!
