Continuing the consolidation on Python for various miscellaneous build and test scripts, this patch moves conformtest from Perl to Python. The substance of the tests run is intended to be the same as before, except that the previous test for tags did not actually achieve the intended purpose of verifying whether a tag was already declared, so is changed to one that would actually fail for a tag that wasn't declared, and a typo in the old test for variables being available ($xyzzy instead of xyzzy) would have made that test not use the correct type (but it would have passed anyway with warnings). No attempt is made to keep the details of what the test output looks like; instead, tests are given names which are made to follow PASS: / FAIL: / XFAIL: / SKIP: / MISSING: as appropriate. In the new version, there is more consistent parsing of test lines (into a series of words, either surrounded by {} or separated by spaces) that applies for all kinds of test lines, rather than the old approach of different regular expressions for every kind of test. A few of the conform/data/ files are adjusted so their syntax works with the new script (which now requires spaces in certain cases where the old script tolerated them being missing, and does not allow stray semicolons at the end of "function" lines). Similarly, common logic is used around what happens with a second subtest if a first one fails (e.g., a test for a symbol's type if the test for availability fails), rather than such logic being replicated separately for each kind of test. Common parsing also applies for test lines both when they are lines for the header under test and when they are lines for another header specified with allow-header, again unlike the old script. Tested for x86_64, and with build-many-glibcs.py. Committed. 2018-11-09 Joseph Myers <joseph@codesourcery.com> * conform/conformtest.py: New file. * conform/conformtest.pl: Remove. * conform/GlibcConform.pm: Likewise. * conform/glibcconform.py (KEYWORDS_C90): New constant.
