14 I have Gentoo installed on a couple of machines without sse. They both
15 have Pentium 2 processors. Although I won't be running valgrind on those
16 machines (desktops for my grand parents) there could be someone else who
17 does.

19 I started thinking that one possible solution would be to have some kind
20 of a subprofile system for different kind of processors. Of course it is
21 a bit of an overkill for just one package but there could be other uses
22 like setting the default CFLAGS and turning on the right use flags for
23 those processors. With these profiles >=valgrind-3.0.0 could be by
24 default in package.mask and unmasked only on the profiles that can use it.
