[FFmpeg-devel] Patch[1/2] to fix bug for PPC LE in file libswscale/ppc/swscale_altivec.c

[rongyan]

Hi,
GCC tool has a bug of PPC intrinsic interpret, which has been fixed in GCC 4.9.1. This bug lead to errors in two of our previous patches. We found this when we update our GCC tools to 4.9.1 and by reading the related info on GCC website. We fix our previous error in two seperate patches:
 1. The first patch is to fix libswscale/ppc/swscale_altivec.c by remove the macro GET_VF().
 2. The second patch is to roll back the commit af5fec9538d88540af5bb2dd0e4b91162ce6fa13 on Apr. 3rd for file libavcodec/ppc/fdctdsp.c, wherer the macros VEC_FMERGEH() and VEC_FMERGEL() are removed.
 This is the first patch.
  
 The fate test result on both BE and LE is as follows:

 
  
 Thanks for your review.
