So far my searches on the web and within kernel (headers)/glibc were fruitless (aux vectors, cpu_user_features), few people people (Hollis Blanchard, Richard Henderson) suggested PPC_FEATURE_ARCH_2_06, but PowerISA_V2.06B_V2_PUBLIC.pdf says - "3.3.11 Fixed-Point Select [Category: Phased-In (sV2.06)]" about isel, the sV2.06 (s part) means something i suppose, furthermore Hollis mentioned that some pre 2.06 cores came with isel. Thanks. -- mailto:av1474@comtv.ru
