--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Working on a patch that moves HLE, MOVBE, CLZERO and MWAITX to isa_flags2 and VBMI2 and SHSTK to isa_flags. The rule of thumb is that if some isa mask option appears with |, then either all the ored options have to be isa_flags, or all isa_flags2, but no mixing.
