avcodec/ppc/fdctdsp: POWER LE support in ff_fdct_altivec() delete macros VEC_FMERGEH() VEC_FMERGEL(), they where 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=8a03d428f1759a7d3af505ab747662747360ea60 --- libavcodec/ppc/fdctdsp.c | 86 +++++++++++++++++++++------------------------- 1 file changed, 39 insertions(+), 47 deletions(-) diff --git a/libavcodec/ppc/fdctdsp.c b/libavcodec/ppc/fdctdsp.c index 80f1366..40f4c6c 100644 --- a/libavcodec/ppc/fdctdsp.c +++ b/libavcodec/ppc/fdctdsp.c @@ -78,14 +78,6 @@ static const vector float fdctconsts[3] = { #define LD_WA vec_splat(cnsts2, 2) #define LD_WB vec_splat(cnsts2, 3) -#if HAVE_BIGENDIAN -#define VEC_FMERGEH(a, b) vec_mergeh(a, b) -#define VEC_FMERGEL(a, b) vec_mergel(a, b) -#else -#define VEC_FMERGEH(a, b) vec_mergel(b, a) -#define VEC_FMERGEL(a, b) vec_mergeh(b, a) -#endif - #define FDCTROW(b0, b1, b2, b3, b4, b5, b6, b7) /* {{{ */ \ x0 = vec_add(b0, b7); /* x0 = b0 + b7; */ \ x7 = vec_sub(b0, b7); /* x7 = b0 - b7; */ \ @@ -393,45 +385,45 @@ void ff_fdct_altivec(int16_t *block) /* }}} */ /* 8x8 matrix transpose (vector float[8][2]) {{{ */ - x0 = VEC_FMERGEL(b00, b20); - x1 = VEC_FMERGEH(b00, b20); - x2 = VEC_FMERGEL(b10, b30); - x3 = VEC_FMERGEH(b10, b30); - - b00 = VEC_FMERGEH(x1, x3); - b10 = VEC_FMERGEL(x1, x3); - b20 = VEC_FMERGEH(x0, x2); - b30 = VEC_FMERGEL(x0, x2); - - x4 = VEC_FMERGEL(b41, b61); - x5 = VEC_FMERGEH(b41, b61); - x6 = VEC_FMERGEL(b51, b71); - x7 = VEC_FMERGEH(b51, b71); - - b41 = VEC_FMERGEH(x5, x7); - b51 = VEC_FMERGEL(x5, x7); - b61 = VEC_FMERGEH(x4, x6); - b71 = VEC_FMERGEL(x4, x6); - - x0 = VEC_FMERGEL(b01, b21); - x1 = VEC_FMERGEH(b01, b21); - x2 = VEC_FMERGEL(b11, b31); - x3 = VEC_FMERGEH(b11, b31); - - x4 = VEC_FMERGEL(b40, b60); - x5 = VEC_FMERGEH(b40, b60); - x6 = VEC_FMERGEL(b50, b70); - x7 = VEC_FMERGEH(b50, b70); - - b40 = VEC_FMERGEH(x1, x3); - b50 = VEC_FMERGEL(x1, x3); - b60 = VEC_FMERGEH(x0, x2); - b70 = VEC_FMERGEL(x0, x2); - - b01 = VEC_FMERGEH(x5, x7); - b11 = VEC_FMERGEL(x5, x7); - b21 = VEC_FMERGEH(x4, x6); - b31 = VEC_FMERGEL(x4, x6); + x0 = vec_mergel(b00, b20); + x1 = vec_mergeh(b00, b20); + x2 = vec_mergel(b10, b30); + x3 = vec_mergeh(b10, b30); + + b00 = vec_mergeh(x1, x3); + b10 = vec_mergel(x1, x3); + b20 = vec_mergeh(x0, x2); + b30 = vec_mergel(x0, x2); + + x4 = vec_mergel(b41, b61); + x5 = vec_mergeh(b41, b61); + x6 = vec_mergel(b51, b71); + x7 = vec_mergeh(b51, b71); + + b41 = vec_mergeh(x5, x7); + b51 = vec_mergel(x5, x7); + b61 = vec_mergeh(x4, x6); + b71 = vec_mergel(x4, x6); + + x0 = vec_mergel(b01, b21); + x1 = vec_mergeh(b01, b21); + x2 = vec_mergel(b11, b31); + x3 = vec_mergeh(b11, b31); + + x4 = vec_mergel(b40, b60); + x5 = vec_mergeh(b40, b60); + x6 = vec_mergel(b50, b70); + x7 = vec_mergeh(b50, b70); + + b40 = vec_mergeh(x1, x3); + b50 = vec_mergel(x1, x3); + b60 = vec_mergeh(x0, x2); + b70 = vec_mergel(x0, x2); + + b01 = vec_mergeh(x5, x7); + b11 = vec_mergel(x5, x7); + b21 = vec_mergeh(x4, x6); + b31 = vec_mergel(x4, x6); /* }}} */ FDCTCOL(b00, b10, b20, b30, b40, b50, b60, b70); _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
