Here's what I'm going to install: libstdc++: xfail rename tests on rtems From: Alexandre Oliva ::rename on RTEMS does not meet several POSIX requirements, despite compliance with C and C++ standards. ::std::filesystem::rename, in turn, has requirements borrowed from POSIX, so it would have to be a lot more than a simple wrapper around ::rename on RTEMS, and even then fall short. Until RTEMS reimplements ::rename for POSIX compliance, expect filesystem rename tests to fail on it. for libstdc++-v3/ChangeLog * testsuite/27_io/filesystem/operations/rename.cc: xfail on rtems. * testsuite/experimental/filesystem/operations/rename.cc: Likewise. --- .../27_io/filesystem/operations/rename.cc | 1 + .../experimental/filesystem/operations/rename.cc | 1 + 2 files changed, 2 insertions(+) diff --git a/libstdc++-v3/testsuite/27_io/filesystem/operations/rename.cc b/libstdc++-v3/testsuite/27_io/filesystem/operations/rename.cc index b74e1133a7618..983374f42e448 100644 --- a/libstdc++-v3/testsuite/27_io/filesystem/operations/rename.cc +++ b/libstdc++-v3/testsuite/27_io/filesystem/operations/rename.cc @@ -17,6 +17,7 @@ // { dg-do run { target c++17 } } // { dg-require-filesystem-ts "" } +// { dg-xfail-run-if "rename is not POSIX-compliant" { *-*-rtems* } } #include #include diff --git a/libstdc++-v3/testsuite/experimental/filesystem/operations/rename.cc b/libstdc++-v3/testsuite/experimental/filesystem/operations/rename.cc index 37e743b770fdf..762b943888f9e 100644 --- a/libstdc++-v3/testsuite/experimental/filesystem/operations/rename.cc +++ b/libstdc++-v3/testsuite/experimental/filesystem/operations/rename.cc @@ -18,6 +18,7 @@ // { dg-options "-DUSE_FILESYSTEM_TS -lstdc++fs" } // { dg-do run { target c++11 } } // { dg-require-filesystem-ts "" } +// { dg-xfail-run-if "rename is not POSIX-compliant" { *-*-rtems* } } #include #include -- Alexandre Oliva, happy hacker https://FSFLA.org/blogs/lxo/ Free Software Activist GNU Toolchain Engineer Disinformation flourishes because many people care deeply about injustice but very few check the facts.
