Yeah, this looks like a bug in newlib. sqrtl is always defined there, it manipulates long doubles' internal representation, but unlike double and float, its ieeefp.h doesn't distinguish between big and little endian. That should be easy to fix by defining another version of struct ieee_ext on big endian systems. -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer More tolerance and less prejudice are key for inclusion and diversity Excluding neuro-others for not behaving ""normal"" is *not* inclusive
