I suppose that depends on the exact nature of the 'check'.
As far as I was aware it was more a case of 'I don't recognise this
processor, so I'll do it the slow but safe way'.
However from what AMD are claiming, it seems to be more of a
'Its an AMD processor so I'll be deliberately slow and buggy'
Having said that, I have tried compiling PG with the intel compiler
in the past, and haven't noticed any real difference. But in a database
there isn't much scope for vectorization and pipelining
compared with numerical code, which is where the Intel compiler
makes the greatest difference.
