The actual code that is wrong is the following:
0x00010670 : ldw 10(r20),r19
0x00010674 : uaddcm r0,r23,r21
0x00010678 : uaddcm r0,r24,r22
0x0001067c : depw,z r19,30,31,r19
0x00010680 : subi 1f,r22,r21
0x000106

Comparing 4.2 to 4.3, the significant difference in main appears to be:
4.2)
ldw 140(%r20),%r19 ;, tmp115
