@Trupti603 At the moment, libc does not support long double as double-double, and together with https://github.com/llvm/llvm-project/pull/190351, we will make sure that the shared libc codes can be built on ppc64le.

I do plan to add proper support all long double options for all targets, starting this year with fp80 and fp128 ([GSoC 2026](https://discourse.llvm.org/t/gsoc-2026-libc-enable-float80-and-float128-math-support-on-unsupported-targets-for-llvm-libc/89647)) and double-double next year.
