Hello,
With target arm-none-eabi, the libstdc++ tests
28_regex/traits/char/isctype.cc and 28_regex/traits/wchar/isctype.cc
fail at

This is because libstdc++ puts '\n' in the 'space' character class,
rather than 'blank' when building on newlib. This problem was known
when suport for the blank character class was added to libstdc++ (see
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01902.html) so this
failure is not unexpected.
Changes to newlib that would have allowed the problem to be fixed were
made (https://sourceware.org/ml/newlib/2009/msg00342.html) but then
reverted (https://sourceware.org/ml/newlib/2009/msg00438.html).
This patch modifies the test to add a special case for the behaviour
with newlib.
Tested by running check-target-libstdc++-v3 -
libstdc++-dg/conformance.exp, with the modified tests, for
arm-none-eabi and aarch64-none-linux-gnu. No new failures and the
modified tests now pass on arm-none-eabi.
Ok for trunk?
I guess the patch is Ok for trunk, but please also add in the comment a
link to this message of yours, that is
https://gcc.gnu.org/ml/gcc-patches/2015-02/msg00059.html.
Thanks,
Paolo.
PS: please remember to always CC libstdc++-v3 patches to
libstd...@gcc.gnu.org.
