   7 // In libavcodec/fft_template.c, fft initialization happens via if statements
   8 // checked on preprocessor defines. On many platforms, these statements are
   9 // culled during compilation. However, in situations where optimization is
  10 // disabled on windows visual studio (PGO, using --disable-optimization in
  11 // mozconfig, etc), these branches are still compiled, meaning we end up with
  12 // linker errors due calls to undefined functions. The dummy functions in this
  13 // file provide bodies so that the library will link in that case, even though
  14 // these will never be called.
