Summary of the bug:
FFmpeg fails to build ffmpeg when optimizations and mmx are disabled.
How to reproduce:
{{{
$ configure --disable-optimizations --disable-mmx
[...]
$ make ffmpeg
[...]
LD ffmpeg_g
libavcodec/libavcodec.a(vorbisdsp_init.o): In function
`vorbis_inverse_coupling_sse':
/home/stefano/src/ffmpeg/libavcodec/x86/vorbisdsp_init.c:61: undefined
reference to `ff_pdw_80000000'
collect2: ld returned 1 exit status
make: *** [ffmpeg_g] Error 1
}}}
Regression since:
{{{
commit fef906c77c09940a2fdad155b2adc05080e17eda
Author: Ronald S. Bultje <rsbultje at gmail.com>
Date: Sat Jan 19 22:21:10 2013 -0800
Move vorbis_inverse_coupling from dsputil to vorbisdspcontext.
Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.
}}}
or the corresponding merge commit.
It builds fine with --disable-optimizations --enable-mmx (but, does it
even make sense?).
