--- Comment #10 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
With the latest trunk (AT14 is similar), the generated code looks like this:
-O
lis %r9,0x8123
ori %r9,%r9,0x4567
rldimi %r9,%r9,32,0
std %r9,0(%r10)
Or
-O3
lis %r11,0x1234
lis %r31,0x2345
lis %r12,0x3456
ori %r11,%r11,0x5678
ori %r31,%r31,0x6781
ori %r12,%r12,0x7812
rldimi %r11,%r11,32,0
rldimi %r31,%r31,32,0
rldimi %r12,%r12,32,0
...
This code seems better than the previous one.
