Comment (by ballapete):

 To me it looks as if just an implementation of some `memalign` function is
 missing:

 {{{
    58   /*
    59    * Allocate align-byte aligned memory. The return value can be
 released
    60    * by calling the dav1d_free_aligned() function.
    61    */
    62   static inline void *dav1d_alloc_aligned(size_t sz, size_t align) {
    63       assert(!(align & (align - 1)));
    64   #ifdef HAVE_POSIX_MEMALIGN
    65       void *ptr;
    66       if (posix_memalign(&ptr, align, sz)) return NULL;
    67       return ptr;
    68   #elif defined(HAVE_ALIGNED_MALLOC)
    69       return _aligned_malloc(sz, align);
    70   #elif defined(HAVE_MEMALIGN)
    71       return memalign(align, sz);
    72   #else
    73   #error Missing aligned alloc implementation
    74   #endif
    75   }
 }}}
