I'm not at all clear on whether any of the people working on AArch64 ILP32
glibc have run the glibc testsuite and investigated the results in detail
(the patch submissions have failed to include glibc testsuite results and
have included bugs that would have been detected by the glibc testsuite).
But, if you've found bugs in a new glibc port that were not detected by
the existing testsuite, then tests for those bugs should be contributed to
glibc (even if no existing port has those bugs, improving the test
coverage is still a good idea).
