swscale/ppc/swscale_altivec.c: POWER LE support in yuv2planeX_8() delete macro GET_VF() it was wrong GCC tool had 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 separate commits Signed-off-by: Michael Niedermayer <michae...@gmx.at> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=603c839398f89d3ef15c47530470fbb0051632c0 --- libswscale/ppc/swscale_altivec.c | 11 ++--------- 1 file changed, 2 insertions(+), 9 deletions(-) diff --git a/libswscale/ppc/swscale_altivec.c b/libswscale/ppc/swscale_altivec.c index 3034c72..af9fc88 100644 --- a/libswscale/ppc/swscale_altivec.c +++ b/libswscale/ppc/swscale_altivec.c @@ -40,19 +40,11 @@ ls = vec_perm(a, l2, c);\ a = l2;\ } -#define GET_VF(a, b, c,d) {\ - a = vec_mergeh(c, d);\ - b = vec_mergel(c, d);\ - } #else #define GET_LS(a,b,c,s) {\ ls = a;\ a = vec_vsx_ld(((b) << 1) + 16, s);\ } -#define GET_VF(a, b, c, d) {\ - a = vec_mergel(d, c);\ - b = vec_mergeh(d, c);\ - } #endif #define yuv2planeX_8(d1, d2, l1, src, x, perm, filter) do {\ @@ -61,7 +53,8 @@ vector signed int i1 = vec_mule(filter, ls);\ vector signed int i2 = vec_mulo(filter, ls);\ vector signed int vf1, vf2;\ - GET_VF(vf1, vf2, i1, i2);\ + vf1 = vec_mergeh(i1, i2);\ + vf2 = vec_mergel(i1, i2);\ d1 = vec_add(d1, vf1);\ d2 = vec_add(d2, vf2);\ } while (0) _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
