for the c code, no.

lkcl at fizzy:~/src/libresoc/openpower-isa$ !fi
find . -name "Makefile"

media/Makefile does not contain any reference to apply_window_standalone.c
or to imdct36_standalone.c

lkcl at fizzy:~/src/libresoc/openpower-isa/media$ ls data/audio/mp3/mp3_0_data/
a.out                      buf3000  buf8000       samples1000  samples6000
apply_window_standalone.c  buf4000  buf9000       samples2000  samples7000
buf0                       buf5000  main.c        samples3000  samples8000
buf1000                    buf6000  out_samples0  samples4000  samples9000
buf2000                    buf7000  samples0      samples5000  win0

no Makefile.
lkcl at fizzy:~/src/libresoc/openpower-isa/media$ ls data/audio/mp3/mp3_1_data/
beforeout1   beforeout5  buf20                 in14  main.c  out3   win19
beforeout2   buf14       imdct36_standalone.c  in3   out18   win12  win8

ah!  found main.c in there.  excellent ok.

i can work with that.

what i propose is, to copy imdct36_standalone.c and main.c into

and commit them

then adjust them to work relative to the media/Makefile directory

then, make a *second* copy which is "a little bit more vector-like"

sound good?
