He doesn't establish whether the code in question is highly cpu-bound or not when run on his system. For a lot of memory- and i/o-bound code, there's little practical difference between gcc with optimisations turned off and gcc with -frice-my-shorts except that the former compiles an order of magnitude faster. The more interesting question, then, is whether users run any non-trivial cpu-bound programs. We know the applied science types do, but they tend to be the ones who're doing clever things with icc anyway. What about normal users? --=20 Ciaran McCreesh --Sig_/b6UWnM_bmPxAh5xbFsoqy4K Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkiAqfsACgkQ96zL6DUtXhHKiACbBOt3xVZnxBmWvlzpm+ZpSjTP FkcAoOHEgW0U5IhdcZtTxf4/SyqE4pyc =IhES -----END PGP SIGNATURE----- --Sig_/b6UWnM_bmPxAh5xbFsoqy4K-- -- gentoo-dev@lists.gentoo.org mailing list
