Browse Source 
* Remove tests we don't need right now.
!!!REVERT THIS COMMIT BEFORE MERGING!!!

* Add s390x testing to drone.

* Correct drone file.

* Correct drone file (again)

* Prevent complete cancellation in bessel_jy logic.

* Correct testing for 128-bit floats.

* Make some more tests 128-bit long double safe.

* Make more tests 128-bit float safe.

* Fix some more 128-bit testing issues.

* More 128-bit float fixes.

* Make more tests 128-bit float safe.

* Fix up remaining tests for 128-bit floats.

* Yet more 128-bit float test case fixes.

* Fix up more tests for 128-bit floats and non-intel platforms.

* Fix up more tests to be 128-bit long double safe.

* More test case adjustments.

* More 128-bit float error rate adjustments.

* Fixes for autodiff tests
