conform: Add initial support for C23.

2025-04-10T18:39:05+00:00

Hi Joseph,

As we discussed, this patch just makes C23 include every check that is
performed by C11.

I tested the commit by adding the ISO23 Make and Python variables to be
the same as ISO11.  So the only difference was compiling with -DISO23
instead of -DISO11.  And changed the temporary directories to instead
use the format f'/tmp/glibc-{self.standard}-{self.header}'.  Then I used
a shell script to run 'cmp' on each file in the ISO11 and ISO23
directories for each header to make sure they were the same.

Make C23 checks include every test that is performed by C11.  Done by
running the following command:

find conform -name '*.h-data' | xargs sed -i \
  -e 's| !defined ISO11| !defined ISO11 \&\& !defined ISO23|g' \
  -e 's| defined ISO11| defined ISO11 \|\| defined ISO23|g' \
  -e 's|ifdef ISO11|if defined ISO11 \|\| defined ISO23|g' \
  -e 's|ifndef ISO11|if !defined ISO11 \&\& !defined ISO23|g'

conformtest: Fix XPG standard naming.

2017-04-27T20:29:35+00:00

The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and
-D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4".

That naming is misleading.  _XOPEN_SOURCE_EXTENDED actually means
XPG4.2, including UX-shaded interfaces.  _XOPEN_SOURCE actually means
XPG4, or XPG4.2 without UX-shaded interfaces.  (Prior XPG versions
also used _XOPEN_SOURCE, but without any versioning of the values of
the macro, so XPG4.2 without UX-shaded interfaces is the only sensible
set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without
_XOPEN_SOURCE_EXTENDED defined.)

This patch fixes the naming in the conform/ tests, so that what is now
called XPG4 is changed to XPG42, and what is now called XPG3 is
changed to XPG4.

Tested for x86_64 (and verified the complete set of expectations is
unchanged by the patch beyond the intended renaming).

Don't declare float / long double Bessel functions for XSI POSIX (bug 18977).

2015-09-16T22:04:40+00:00

The float and long double versions of Bessel function (j0f, y1l, etc.)
are not in POSIX; only the double versions are.  This patch
accordingly limits the declarations of those functions to __USE_MISC,
and fixes the conform/ test expectations which matched the previous
incorrect declarations.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by this patch).
