Does anyone have a worked example in C of using attribute ifunc to dispatch over the various x86 SSE/AVX flags, as well as arm neon? Must one call cpuid manually, or are flags already available to check? I haven't found any via goog (and the C++ example I found was incompatible with the gcc-4.6 syntax for ifunc), and glibc's support for it is too opaque for grep.
