That was not urban legend.  It happened.  You can find threads here a few
years back where folks were complaining about Crafty crashing on AMD processors.
We found that things like CMOV were missing at the time, yet AMD was claiming
compatibility.  Not a huge problem, but it _was_ a problem that caused me a
_lot_ of email and testing to discover what it was.  There have been a few other
such cases, CMOV wasn't the only thing.  3DNow was another thing that seems
pretty pointless, since Intel dominates sales, who is going to take the risk of
using non-Intel stuff?  Not many software developers will, and we end up with
_another_ incompatibility.

That happens everywhere.  Eg "windows" from Microsoft...

As I said, I'm not anti-AMD.  I'm simply an Intel fan from past product
experience.  I'm also an alpha fan.  And a Cray fan.  And in each of those
cases, those vendors were the _leaders_.
