Here's the situation. I have a system that's been running for many years |
2 |
with an Athlon 5050e processor. The system is built with |
3 |
|
4 |
CFLAGS="-march=k8-sse3 -O2 -pipe -msse3" |
5 |
CPU_FLAGS_X86="3dnow 3dnowext mmx mmxext sse sse2 sse3" |
6 |
|
7 |
I have the possibility of upgrading the system to a first-generation Intel |
8 |
Core i5 which should give a nice speed boost, but of course the Intel chip |
9 |
doesn't understand 3dnow or 3dnowext, so I'll have to do a system rebuild |
10 |
before I switch out the motherboard/processor. It seems pretty obvious that |
11 |
I have to take "3dnow 3dnowext" out of CPU_FLAGS_X86, but what CFLAGS would |
12 |
be recommended for a system that will still run with the AMD processor but |
13 |
won't fall over when I switch to the Intel processor? Once I have the Intel |
14 |
in place I can rebuild with options more suited for that chip, but I want |
15 |
to make sure I don't end up in a catch-22 situation. |
