P4 optimisation (CPUTYPE=p4) is not stable.


I've testet building a gcc34 system on a Pentium 4 and on an Athlon PC now. My /etc/make.conf looks like this on both PCs (no CPUTYPE flag):
# cat /etc/make.conf
CCVER= gcc34
CFLAGS= -O2 -pipe

I've refetched the complete DragonFly_Stable sources today, and simply did "make buildworld && make buildkernel && make installworld && make installkernel". Building, as always, went without problems, but, the man-Problem (i.e. "man man") and the "make buildworld problem" (when trying to build the system again after the upgrade), as described in my previous mail, persist on both PCs.

When I restore and install my old gcc2.9 /usr/obj-tree, and then build the system (with exactly the same sources) without defining CCVER= gcc34 in /etc/make.conf, I don't have any problems.

So gcc29 works and gcc34 doesn't work with DragonFly_Stable on my PCs. But why? Any more hints where to look?
