Subject: [Bug optimization/15386] WMA decoder miscompiled with -O4 -mcpu=k6 - one pop, no sound

One of the things that would really help us is if you could split
up the one file that is miscompiled into a number of files each
of which has exactly one function, and try to figure out which
function is miscompiled. One of the reasons why we have trouble
doing anything with your report except for poking in the dark is
because it is very hard to figure out what exactly goes wrong in
applications that we don't know, and we usually need quite some help
from application developers to figure out where the bug is. So if
you could try to cut the problem down to one or a few functions, it
would be a tremendous help. The next step is to determine for which
arguments this function does the wrong thing, and to put together
a small testcase where this one function is called with just these
parameters for which the output is known.
Thanks
Wolfgang
