However, I get the following errors: /home/marxin/Programming/gcc/gcc/wide-int-bitmask.h:26: undefined type `constexpr' /home/marxin/Programming/gcc/gcc/wide-int-bitmask.h:26: undefined type `constexpr' /home/marxin/Programming/gcc/gcc/wide-int-bitmask.h:26: undefined type `constexpr' Just for the record, right now, there are 26 free bits available in ix86_isa_flags2.
