I dont have a HPPA system to test this

the following passed on qemu-hppa
../configure  --target-exec='qemu-hppa  -L qemu-hppa -L /usr/hppa-linux-gnu/' --samples=/home/michael/fatesamples/fate/fate-suite/ --enable-gpl --cross-prefix=/usr/hppa-linux-gnu//bin/ --cc='ccache hppa-linux-gnu-gcc' --arch=hppa --target-os=linux --enable-cross-compile
make -j32  fate-filter-aemphasis-50fm

on n8.0.1

the way to investigate this is to look at the output from the filter (teh audio not the crcs)
and if its all +- 1 then its some FPU rounding difference
and in that case the test is the problem and needs to be made more tolerant
otherwise if there are lareg differences
then theres a real bug somewhere, this can be searched systematcially
by adding lots of printf() and comparing until you find where the issue starts

but as it doesnt replicate with qemu thats something you or someone
who has access to a box where this replicates needs to look into

also i admit iam quite overloaded with work so i would prefer if
someone else looks into that quiet a bit over someone giving me
access to a HPPA ;)

thx
