--- Comment #8 from Paul E. Murphy <murphyp at linux dot vnet.ibm.com> --- The new libm/libc ABI for ieee128 long double on ppc64le is now committed to glibc which will be available for the 2.32 release (commit 051be01f6b41a1466b07ae4bd7f5894a8ec5fe67). TS-18661 does not specify any changes to the printf/scanf family of functions as related to _FloatN types. It won't always be a drop in replacement.
