Hi,
On this page:
http://gcc.gnu.org/gcc-3.4/changes.html
one sees these lines in the IA-32/AMD-64 section:
---------------------------- 8< ----------------------------
* Tuning for K8 (AMD Opteron/Athlon64) core is available
via -march=k8 and -mcpu=k8.
[...]
* -mcpu has been renamed to -mtune.
---------------------------- 8< ----------------------------
IMHO, the order of these sentences should be reversed
and the "-mcpu" in the first line changed to "-mtune"
like so:
