--- Comment #1 from Michael Meissner <meissner at gcc dot gnu.org> 2012-05-02 19:16:26 UTC ---
If you compile the following with -mcpu=power6 -m64:
long long
b64 (long long *p)
{
return __builtin_bswap64 (*p);
}
Using the -mno-avoid-indexed-addresses works around the problem. Setting
cpu=power5 works because -mcpu=power5 does not set -mavoid-indexed-addresses by
default. Setting -mcpu=power7 works because the power7 has a 64-bit load and
reverse bytes instruction.
