--- Comment #10 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Adrian Wielgosik from comment #9) > TOTAL : 0.97 0.01 0.99 > 119627 kB By passing in the length of the first sequence instead of using sizeof... the std::make_integer_sequence result comes down to: TOTAL : 0.23 0.01 0.25 15114 kB Which is very reasonable, and within an order of magnitude of Daniel's, which I think is good enough (especially if we're going to get a compiler intrinsic eventually anyway). But rather than making that change I think the right thing to do is to fix the front-end so that sizeof... doesn't make such a big difference and we don't have to jump through hoops to avoid it. I'll file a PR for that tomorrow.
