can't use math function "floor" in a kernel

[ghost]

When using the function "floor" from math.h in a kernel, coriander compiles and link the CUDA code fines, but at run time, the linked binary produces the following error:

OpenCL platform: Intel Gen OCL Driver
OpenCL device: Intel(R) HD Graphics Kabylake ULT GT2
llvm.floor.f32 is called, but not defined
This is probalby a bug in Coriander. Please file an issue at https://github.com/hughperkins/coriander/issues/new
basicblockdumper.runGeneration got exception whilst processing:
