libdfp currently isn't Fedora. glibc doesn't use _Decimal, so I don't
see how these things are related.
Would you please elaborate?
I though we here talking about a distro and supporting the platform.
GLIBC is too narrow a topic.
POWER supports IEEE754R Decimal Floating Point in Hardware, Since Power6
(2007).
_Decimal is included in C14 and C17 standards.
libdfp is NOT new (also circa 2007) And is included in RHEL6 RHEL7 and
other enterprise distros (Supplement or extras)

We cant use the messed up BID code and format from X86. Which is
software emulation only.
So the question is: why doesn't Fedora build and ship libdfp.
