1 Hello
2
3 Portage 2.0.48 came with the following warning.
4
5 # CRITICAL WARNINGS:
6 ****************************************************** #
7 # ATHLON-4 will generate invalid SSE instructions; use 'athlon'
8 instead. #
9 # PENTIUM4 will generate invalid SSE2 instructions; use 'pentium3'
10 instead. #

12 *************************************************************************
13 However, now that gcc 3.2.3 is on ~x86 I would just like to seek the
14 affirmation of the devs that the new gcc does resolve these bugs before
15 I move from -march=pentium3 to pentium4. Is it now safe to use p4 by
16 recommendation?
17
18 Out of curiousity how about athlon-4?

20 Many thanks
