assembly instruction set for my processor

Question

Dear all, this is a simple question, I think. How do I find the instruction set for my processor? proc/cpu gives me (a vanilla cpu):

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 23
model name      : Intel(R) Core(TM)2 Duo CPU     T6600  @ 2.20GHz
stepping        : 10
cpu MHz         : 1200.000
cache size      : 2048 KB

where do I find documentation about the instruction set for this? I'd like to get info to unlock gcc's .s files to know how it's translating my code. Please accept my apologies if the question is not clear, I'll be happy to clarify. Thanks.

You want the "Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 2A: Instruction Set Reference, A-M" and the "Intel® 64 and IA-32 Architectures Software Developer's Manual Volume 2B: Instruction Set Reference, N-Z".
