--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> --- The default -mcpu= for a compiler targeting powerpc64le-linux is normally power8 (you can change this with the --with-cpu= configure option though). -mcpu=powerpc64le is also (currently) equal to -mcpu=power8. But the numbers for Power8 (in power8_cost) are wrong it seems: it has a 64kB L1-D cache, and a 512kB L2 cache (it looks like we have simply copied the Power7 numbers here; 32 and 256 is correct for Power7).
