From 21f8ce2a4b94034284eb74b9c3b4c9cc638511d6 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Fri, 17 Jan 2014 22:26:11 +0000 Subject: tune-corei7: Add support for cpu-type corei7 corei7 offers a significant advancement since the previous core2 cpu-type described in the tune-core2 file. From the GCC(1): Intel Core i7 CPU with 64-bit extensions, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1 and SSE4.2 instruction set support. This offers optimizations for Nehalem and Silvermont (e.g. Bay Trail) CPUs (and beyond).
