run glibc tests on newlib? They likely have tests for this for
newlib's purposes.
It would be interesting to see results of glibc libm tests (current git
please, there have been major changes since the last release) for a range
of libm implementations and operating systems, but also probably a lot of
work to get them building with other C libraries; they make plenty of use
of glibc features, include some internal glibc headers for configuration
of some details of the architecture, and hardcode glibc choices of goals
for errno, exceptions and accuracy that other libm implementations may
differ on. An implementation/architecture-specific libm-test-ulps file
also needs to be generated before you can expect clean results even for an
implementation following glibc's goals.
