            Bug ID: 249863
           Summary: SSE2 is enabled by default on amd64, but is not
                    enabled by default on i386
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: misc
          Assignee: bugs at FreeBSD.org
          Reporter: yuri at freebsd.org

For example, the port misc/vxl r526931 fails on i386 because cmake can't find
SSE2 enabled in the base compiler:
http://beefy17.nyi.freebsd.org/data/head-i386-default/p549547_s365984/logs/errors/vxl-2.0.2.629.log
but it normally succeeds on amd64 because SSE2 is enabled in the base compiler.

The defaults for SSE2 being enabled should be the same on both i386 and amd64
because the SSE status doesn't depend on the mode being 32-bit or 540-bit.
