[FFmpeg-devel] Report a bug for commit b67bcd784dde7ad2b1a167ce7ffef14f8a0c8074

[rongyan]

Hi,
  
 In the commit b67bcd784dde7ad2b1a167ce7ffef14f8a0c8074, the changes make gnu_as disabled, so HAVE_GNU_AS is disabled as a result, and the altivec code for ppc is not used. For example, in fft_altivec.c, the conditions "#if HAVE_GNU_AS && HAVE_ALTIVEC" is not ture, so altivec code will not be used.
