The initial buildbot run found a few missing bits in the initial XFAIL list
for the no-exceptions libc++ variant. These discrepancies are as follows:
[1] Following two tests need XFAILs on the no-exceptions library variant.
My local runs had these two disabled for other reasons (unsupported):
- localization/locales/locale/locale.cons/char_pointer.pass.cpp
- numerics/complex.number/complex.ops/complex_divide_complex.pass.cpp
[2] These three does not need XFAILs, they were failing on my local runs for
other reasons:
- depr/depr.c.headers/uchar_h.pass.cpp
- input.output/iostreams.base/ios/basic.ios.members/copyfmt.pass.cpp
- .../category.collate/locale.collate.byname/transform.pass.cpp
(these are failing on my box for the default build as well)
The current patch fixes both the cases above. Additionally, I've run the
following scan to make sure I've covered all the cases:
> grep ' catch \| try \| throw ' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
uniq > 1.txt
> grep 'libcpp-no-exceptions' -R . | perl -pe 's|(.*?):.*|\1|' | sort | \
uniq > 2.txt
> diff 1.txt 2.txt
This showed up a few extra interesting cases:
[3] These two tests do not use try/catch/throw statements, but they fail at
runtime. Need to be investigated, I've left the XFAILs in.
- std/thread/futures/futures.shared_future/dtor.pass.cpp
- std/thread/futures/futures.unique_future/dtor.pass.cpp
[4] These tests use a macro named TEST_HAS_NO_EXCEPTIONS to conditionally
exclude try/catch/throw statements when running without exceptions. I'm not
entirely sure why this was needed (AFAIK, we didn't have a no-exceptions
library build before). The macro's defintion is quite similar to that of
_LIBCPP_NO_EXCEPTIONS. I will investigate if this can be reused for my test
fixes or if it should be replaced with _LIBCPP_NO_EXCEPTIONS.

Fixes a small omission in libcxx that prevents libcxx being built when
-DLIBCXX_ENABLE_EXCEPTIONS=0 is specified.
This patch adds XFAILS to all those tests that are currently failing
on the new -fno-exceptions library variant. Follow-up patches will
update the tests (progressively) to cope with the new library variant.

On a system with LC_COLLATE=C, this takes precedence over a non-C LANG
the test tries to impose and the test fails.

The time_put test doesn't seem to work on Linux and CloudABI. For Linux
we already have an XFAIL. Closer inspection seems to reveal that this
test does not pass for a couple of reasons.
First of all, the tm_yday field is set to an invalid value. The
strftime() function doesn't behave consistently across platforms in case
the values in the tm structure are incoherent. Fix up this field to have
the value 121, which corresponds with tm_mday, tm_mon and tm_year. This
of course affects the output of time_put for some modifiers, so update
the tests accordingly.
Second, some of the tests actually use modifiers that are only present
on BSD derived systems. They are not part of the C standard/POSIX.
Simply remove them.
Finally, some of the tests actually use invalid modifiers, causing a
malformed format string to be passed to strftime(). Remove these tests
as well.

Summary:
MSAN and ASAN also replace new/delete which leads to a link error in these tests. Currently they are unsupported but I think it would be useful if these tests could run with sanitizers.
This patch creates a support header that consolidates the new/delete replacement functionality and checking.
When we are using sanitizers new and delete are no longer replaced and the checks always return true.
