• 4df87bb7b   lib: add weak clz/ctz functions ... Browse Code »

  Some architectures need __c[lt]z[sd]i2() for __builtin_c[lt]z[ll] and
  that causes a build failure. They can be implemented using the
  fls()/__ffs() and overridden by linking arch-specific versions may not
  be implemented yet.

  This is required by "lib: add lz4 compressor module".
