В RELNOTES к FreeBSD 5.2.1 написано:
GCC has been updated from 3.2.2 to a 3.3.3 pre-release snapshot from 6
November 2003.
Note: Previous versions of GCC generated incorrect code when
-march=pentium4 optimization was enabled. This problem is believed to
have been fixed with this upgrade, and the earlier workaround for the
case of CPUTYPE=p4 has been removed.
т.е. если я правильно понял "все версии gcc до 3.3.3pre, в т.ч. 3.2.2
создают неправильный код при -march=pentium4"
Вопрос: это только в FreeBSD неправильный код генерит gcc <3.3.3?
3.2.3 нормальная версия?
