--- Comment #4 from Julian Seward <jseward@acm.org> ---
gcc-4.7.2 that is installed on gcc110.fsffrance.org generates this:
0000000010000610 <.foo>:
10000610: 81 23 00 00 lwz r9,0(r3)
10000614: 75 2a 07 00 andis. r10,r9,1792
10000618: 4c 82 00 20 bnelr
which is the same scheme as clang uses for x86_64. Hence no complaint.
I don't have access to a ppc box with clang installed, so I can't repro the
problem. Hmm.
