Comparing 4.2 to 4.3, the significant difference in main appears to be:

4.2)

        ldw 140(%r20),%r19      ;, tmp115
        extru %r19,31,3,%r29    ; tmp115,, tmp113
        zdep %r28,28,29,%r21    ;,,
        extru %r29,2,3,%r19     ; tmp113,, tmp117
        zdep %r29,28,29,%r22    ; tmp113,, tmp116
        or %r19,%r21,%r21       ; tmp117,,
        ldi 0,%r28      ;, tmp122

4.3)

        ldw 140(%r20),%r28      ;, tmp115
        zdep %r28,28,3,%r24     ; tmp115,,, tmp116
        ldi 0,%r28      ;, tmp122
