As Paul noted, he'd tested the operation of the new functions, but there has been no review of the detailed contents of the patch that achieve adding those functions to glibc. So the following still need review and discussion: > (a) the actual content of the patch, which no-one has commented on > (instead preferring to suggest other things to add to it); > > (b) the questions of what goes in such patches, where I argue that we > should not expect libm-test-ulps updates for more than one architecture, > or additional test inputs based on searches for worst-case inputs, to be > included in such a patch: that it should be sufficient to include > libm-test-ulps updates for a single architecture, and tests that seem > appropriate based on the mathematical properties of the function being > tested, and further additions there can reasonably be made in followup > patches. (Note that even if we moved to a single libm-test-ulps shared > between architectures and listing expected ulps based on floating-point > format rather than type, it still wouldn't be possible to update all ulps > on a single system: no architecture supports both ldbl-96 and > ldbl-128ibm.) -- Joseph S.
