Another curious difference is that x86 uses an instruction decoder and contains massive tables to validate we can probe a particular instruction. Can we probe all possible PPC instructions? _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
