--- Comment #1 from Michel Dänzer michel@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.
