--- Comment #2 from Christophe Leroy <christophe.leroy at csgroup dot eu> ---
Problem still present with GCC 11.2
Linux kernel has a huge amount of sequences like:
b4: 3d 20 fc ff lis r9,-769
b8: 61 29 ff ff ori r9,r9,65535
bc: 79 29 07 c6 rldicr r9,r9,32,31
c0: 65 29 ff ff oris r9,r9,65535
c4: 61 29 ff ff ori r9,r9,65535
c8: 7d 3d 03 a6 mtamr r9
Could instead be:
li r9, -769
rotldi r9, r9, 48
