As expected, > the arm shows some tests failures due the missing kernel support: I'd expect tests on an older kernel to be UNSUPPORTED, not FAIL. More precisely: tests of times that can be represented in 32 bits, but using the 64-bit interfaces, should be PASS, and tests of times that can't be represented in 64 bits should be UNSUPPORTED as long as those are in a separate testcase from the tests of times that can be represented in 32 bits. If in the same testcase, FAIL seems the worst result, since it's not indicating any bug in glibc. -- Joseph S. Myers joseph@codesourcery.com
