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.

This patch fixes the conformtest handling of headers listed in
allow-header to process xfail[cond]- in the expectations for those
headers.
Tested with build-many-glibcs.py.
* conform/conformtest.pl: Handle xfail[cond]- in header mentioned
with allow-header.

This patch makes conformtest skip execution tests when
cross-compiling, as an interim step towards running most of these
tests (presently disabled) in that case. It omits the (obvious)
Makefile change to actually enable the conformtest tests when
cross-compiling, as there are still enough failures seen with
build-many-glibcs.py that I'd like to get the results cleaner before
enabling these tests.
Tested for x86_64, and with the tests actually enabled for
cross-compilation with build-many-glibcs.py.

(runtest): Skip test execution when cross-compiling.

conformtest has an internal XFAIL mechanism to allow failures of
individual expectations to be ignored, so that known hard-to-fix
failures (e.g. those affecting ABIs or requiring kernel changes) do
not cause the overall tests to FAIL and so hide other failures from
the same (header, standard) pair.
Various such bugs are system-specific, so this patch adds a mechanism
to allow system-specific XFAILs. A system-independent XFAIL is
achieved by putting "xfail-" at the start of the relevant expectation
in the *-data files. A system-specific XFAIL instead uses
"xfail[cond]-", where "cond" is a condition listed in
conformtest-xfail-conds in a sysdeps makefile (so one for x32 might
set conformtest-xfail-conds = x86_64-x32-linux, for example, and then
an expectation for tv_nsec's type could use
xfail[x86_64-x32-linux]-). The actual names are arbitrary, just
needing to match between the makefiles and the expectations, and if
necessary you can use "xfail[cond1|cond2]-" for a test that is
expected to fail under multiple conditions. As with
system-independent XFAILs, I think system-specific ones should have a
bug filed in Bugzilla and a comment referencing that bug.
Tested for x86_64, including with test expectations and makefiles
changed to use the new facility.

The conformtest header tests test some things through compilation
tests and others through execution tests. This patch makes more of
the tests into compilation tests, using _Static_assert (note: for
float.h tests on floating-point values this is depending on a GNU
extension, that those assertions are allowed in the absence of
-pedantic although they aren't strictly integer constant expressions).
The remaining execution tests are for values of things listed as
"symbol" (in fact no such things have a value expectation listed) and
for values of macros defined as string constants (three such values
listed in total).
This is intended as preparation for enabling the vast bulk of the
tests to run for cross compilation. (Even the few remaining execution
tests ought in principle to run for cross compilation when a test
wrapper is defined, but that's more complicated. The existing
execution tests for native builds in fact are linked and run with an
existing installed libc that's required to exist to link against,
rather than with the newly built libc; only the new headers are used.)
Tested for x86_64.
* conform/conformtest.pl: Use compilation instead of execution
tests for testing values of constants and usability in #if.

Various conformtest tests fail because of known issues, filed in
Bugzilla, that are hard to fix (requiring new features, kernel
cooperation or involving changing types in ways that may involve care
around padding when interfacing to the kernel). Such an issue has the
effect of making the whole test for the (standard, header) pair fail,
so hiding any other issues with that header for that standard
(possibly regressions or architecture-specific issues).
This patch adds a mechanism for individual conformtest test
expectations to start with xfail-, meaning that a failure of that
particular assertion does not cause the whole test to fail at the
makefile level and so failure at the makefile level can be used to
detect other issues that are likely to be easier to fix. This is
similar to the whitelisted symbols in the linknamespace tests, or the
marking of particular libm tests as allowing spurious or missing
exceptions, for example. The bugs filed in Bugzilla should still be
fixed, and the xfail- markers removed at that point, but xfail-
renders the tests more useful until that happens.
Note that there is no way to add such a marker for the assertion that
a header uses only symbols in the namespace of symbols it's meant to
use. I don't think there's any need for a way to xfail those
namespace tests other than xfailing the whole (standard, header) pair
at the makefile level, since they are generally straightforward to fix
(add appropriate conditionals on the problem definitions).
The xfails in this patch do not necessarily cover all cases of
hard-to-fix header bugs filed in Bugzilla that currently show up in
conformtest failures; there may be more yet to add for existing open
bugs.

One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.
This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests). The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option. The following comment from
linknamespace.pl explains the caveats around this approach:
Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards). (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

This patch adds the -std=c99 option when preprocessing the data files
from the conform testcases. It fixes an issue where the compiler may
split the 'macro bool' defition from stdbool.h-data in two lines and
thus breaking the conform script.

Continuing the series of patches to clean up conformtest expectations
for "POSIX" (1995/6) based on review of the expectations against the
standard, this patch cleans up those for semaphore.h, signal.h and
tar.h (including various corrections for other standards for the
expectations affected by this patch). Tested x86_64.
(Some of the failures for signal.h shown up by this patch correcting
expectations for that header are among the reasons for posix/annexc
being expected to fail. The goal is for conformtest eventually to
replace posix/annexc and stdlib/isomac once it has all relevant
functionality, and for the loop over standards and headers in
conformtest to convert to separate makefile targets for each
combination, so they can be run in parallel and so that xfails can be
more specific than the present xfailing of the whole of conformtest.)
