Counting FP multiplies on Core 2

From: Paul Mackerras

The Intel manual tells me that event num 12H, umask 00H on Core 2
counts multiply operations executed, but says "Use IA32_PMC1 only".
Is there a way in the raw event code to specify a particular PMC, or
does the code just know that that event can only be counted on PMC1?

Paul.
