[PATCH] D54313: [compiler-rt][builtins][PowerPC] Add floattitf builtin compiler-rt method support for PowerPC

[Robert Enenkel via Phabricator via llvm-commits]

renenkel added a comment.

Masoud wrote a test program that exercises the conversions over the full range of exponents and compares the results to the gcc conversion.  My understanding is that the results matched except for the long double NaN (which is arbitrary), and some long doubles with interspersed 0's between the high and low double, for which it was possible to determine that the gcc result was wrong (Masoud, please confirm?)
