When I look at the gcc manual under the option -mtune for optimizing the generated code, it requests to know what type of processor you have. There are 3 listed under i7:
corei7 corei7-avx core-avx-i
The manual lists the instructions it expects to find incorporated into each architecture. But I cannot find on Intel where the instructions for the different processors are specified. The last time I did Intel, about 6 years ago, I recall this data being available. While I was with AMD Opterons things appear to have changed.
I am looking for what subset of the following extensions are supported in the i7-4940, or in general for any other Intel processor.
MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AES, PCLMUL, FSGSBASE, RDRND and F16C
Please let me know if this is the wrong list, with suggestions please.

I do not know if it is the same as i7-4940MX (the only one found on Intel site); according to http://ark.intel.com/products/78940/Intel-Core-i7-4940MX-Processor-Extreme-E... i7-4940 supports AVX 2.0. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
