--- Comment #4 from Kostya Serebryany <kcc at gcc dot gnu.org> --- Why can't we use frame pointers on PPC? So far I have not seen any implementation of unwinder not based on FPs that was fast enough for ASan. ASan unwinds the stack on every malloc/free and thus it is very sensitive to the unwinder performance.
