.... Although this may be generally better than loading each field on its own, this can lead to poor code generation when the operations extracting the fields are more expensive than a load or when “fancy” loads are available. More generally, this may happen for smaller size too. ** Example ** 1. %chunk64 = load i64 2. %field1trunced = trunc i64 %chunk64 to i32 // <— build field1 from chunk 3. %field1float = bitcast i32 field1trunced to float // <— build field1 from chunk 4. %field2shifted = lshr i64 %chunk64, 32 // <— build field2 from chunk 5. %field2trunced...
