Re: MACRO_INSTS double definition on Nehalems

> Andi, is http://www.intel.com/content/dam/www/public/us/en/documents/manuals/64-ia-32-architectures-software-developer-system-programming-manual-325384.pdf the official document that should be reference for this? Tables 19-1 and Table 19-17 look to be the table to refer to for Nehalem.

I would use https://download.01.org/perfmon/NHM-EP/

Sounds reasonable to me.
