cpu_dispatch is a nice feature
How can I use cpu_dispatch to differentiate architectures where shld instruction (1 cycle on SNB only) is faster than rotl (faster on all previous and following cpu types, like NHM and IVB)
How can I get the list of supported identifiers which seem to follow an exotic naming convention "core_2nd_gen_avx""core_i7_sse4_2" ...
Is it possible to use documented cpuid flags in cpu_dispatch clause (like sse4.2,aes,pclmul,rtm) , rather than undocumented names ?
