--- Comment #16 from Ard Biesheuvel <ardb at kernel dot org> --- OK, so in summary, the fallthrough for CM_SMALL_PIC/CM_MEDIUM_PIC should be removed, and instead, a 'call mcount@PLT' should be emitted. I suppose this should check for -fno-plt as well, and revert to 'call *mcount@GOTPCREL(%rip)' in that case?
