[committed] libstdc++: Disable PCH for tests that rely on include order
Checks
Commit Message
Now that no_pch works, I can use it to fix this test that was failing
with PCH enabled and run with -std=gnu++23.
Tested x86_64-linux. Pushed to trunk.
-- >8 --
These tests expect to be able to #undef a feature test macro and then
include <version> to get it redefined. But if <version> has already been
included by the <bits/stdc++.h> PCH then including it again does nothing
and the macro remains undefined.
libstdc++-v3/ChangeLog:
* testsuite/24_iterators/move_iterator/p2520r0.cc: Add no_pch.
* testsuite/std/format/functions/format.cc: Likewise.
* testsuite/std/format/functions/format_c++23.cc: Likewise.
