That's not logically correct, because this is an issue about exponent range, not precision; it's fine to test this input value when converting from TImode to float, for example, because it's 2**127 which is exactly representable in float. I'll do another revision of the patch that addresses this and has other testsuite improvements (but no changes to the actual compiler changes, which still need review for language-independent changes outside the rs6000 back end). -- Joseph S.
