Hi,
std.math.internal.gammafunction is the last module with failing
unittest on ARM, simply because it assumes that reals are
always in
x86 extended precision format which is obviously not true on
ARM.
I haven't got the required (maths) knowledge to fix this, so
it'd be
very appreciated if somebody could take a look.
It's actually possible to easily test this on x86 with gdc:
Just install
a recent gdc build and use the -mlong-double-64 command line
argument.
More details and bug report here:
https://issues.dlang.org/show_bug.cgi?id=13032
some trial and error suggests that gammaStirling needs it's
threshold changing from 1024.0L to 143.0L when using 64bit
reals to avoid overflow.
MAXGAMMA will also need changing. I don't think there's anything
else wrong with gamma and gammaStirling, I haven't looked at the
others yet.
