Replying to [comment:8 dukeleto]:
> I've never seen the --floatval flag before. Does anyone run the test
suite with it on? Does it work? I would prefer a configure-time check for
powl, before using it.
As I said above, it used to mostly work. As I recall, there were a few
PBC issues and some broken tests, but they were mostly bad tests.
While you are correct that a Configure probe would be useful (see TT #1048
for some thoughts on that) I think my patch should be applied in the
meantime. With my patch above, parrot won't normally try to use powl
unless the user explicitly asks for {{{ --floatval='long double'}}}. I
don't think a user without a working powl function is likely to ask for
long doubles.
I'm actually puzzled how the old version could have blocked RTEMS, unless
they were somehow effectively using {{{--floatval='float'}}}. I don't
know if that has ever worked.
