--- Comment #1 from Michel Dänzer <michel at daenzer.net> ---
This happens since Mesa commit d72a26ec ("radeonsi: don't emit AMDGPU
intrinsics for EX2, ROUND, TRUNC") because the LLVM function
LibCallSimplifier::optimizeExp2() replaces the llvm.exp2.f32 call (which could
be handled by the AMDGPU backend AFAICT) with an ldexpf one.
