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)
https://github.com/libdfp/libdfp
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.
weren't there any licensing issues originally? And later no one
volunteered to maintain it it seems :-(
