Yes, it's turned off by default in rs6000 here:
static const struct default_options rs6000_option_optimization_table[] =
{
...
/* -frename-registers leads to non-optimal codegen and performance
on rs6000, turn it off by default. */
{ OPT_LEVELS_ALL, OPT_frename_registers, NULL, 0 },
...
}
I'm going to handle it.
