This came up during a discussion on #129679, which has been split out as a preparatory commit. An example of the AMDGPU codegen is: define <2 x float> @_Z10native_expDv2_f(<2 x float> %val) { %mul = fmul afn <2 x float> %val, splat (float 0x3FF7154760000000) %0 = extractelement <2 x float> %mul, i64 0 %1 = tail call float @llvm.amdgcn.exp2.f32(float %0) %vecinit.i = insertelement <2 x float> poison, float %1, i64 0 %2 = extractelement <2 x float> %mul, i64 1 %3 = tail call float @llvm.amdgcn.exp2.f32(float %2) %vecinit2.i = insertelement <2 x float> %vecinit.i, float %3, i64 1 ret <2 x float> %vecinit2.i } define <2 x float> @_Z11native_exp2Dv2_f(<2 x float> %x) { %0 = extractelement <2 x float> %x, i64 0 %1 = tail call float @llvm.amdgcn.exp2.f32(float %0) %vecinit = insertelement <2 x float> poison, float %1, i64 0 %2 = extractelement <2 x float> %x, i64 1 %3 = tail call float @llvm.amdgcn.exp2.f32(float %2) %vecinit2 = insertelement <2 x float> %vecinit, float %3, i64 1 ret <2 x float> %vecinit2 }
