So, let's ask Dave and Andreas for testing of this patch,

Tested on top of e2dbf201abdfa13fc4035a1a8888ecec91bef44c together with the build fix from David.



Andreas, could you baseline the files again, please?



We've made many corrections in the last months, so some ULPs should be
smaller as well - did you really start with an empty file? If not,
please redo and commit.

Yes it was a fresh start. The values appear to be similiar to e.g. sparc. Where did you expect different values?

On x86-64 we had some lower values but I don't remember which ones.

Do you have git access or shall I commit the change for you? This is for s390-64, isn't it?

The only change I did manually was removing the logb values as suggested by Joseph:

<  # logb

Sure, those were wrong,
