    PPC asm for AV_RL*() · 9f5ff83f
    Måns Rullgård authored
    PPC is normally big endian but has special little endian load/store
    instructions.  Using these avoids a separate byteswap.  This makes the
    vorbis decoder about 5% faster.  Not much else uses little-endian
    read/write extensively.
    
    GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
    a packed struct), so we override it with a plain pointer cast.
