OS X : llvm.fmuladd.f32 could not be found


I’ve got some strange errors on all my kernels when I build them on a GeForce 9400 :

[CL_BUILD_ERROR] : OpenCL Build Error : Compiler build log:
kernel referenced an external function llvm.fmuladd.f32, that could not be found.

My platform is OS X and the “multiply-add” option is not enabled.
All these kernels work properly on all other graphic boards that I could test, and on CPUs.

Any idea ?
