[LLVMdev] double* to <2 x double>*
Does anyone know how to instrument *double* to <2 x doulbe>**, e.g., 2.2 --> <2.2, 2.2>? For example, I want to change the following IR code %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = load double* %arrayidx1, align 4, !tbaa !0 to: %arrayidx1 = getelementptr inbounds [100 x double]* @main.B, i32 0, i32 %i.021 %1 = bitcast double* %arrayidx1
