[cfe-dev] New Windows libc++ test results

Hi,
I have an update to the test results for libc++. Clang can now correctly
handle exceptions if the GCC it uses the libgcc from is compiled for dw2
exceptions, which only works on 32-bit Windows.
So all the false negatives should be filtered out currently, leaving the
real issues. I have attached a patch to the results.windows.html web page
detailing the changes.
Current tally is:
6.7% test failures, 9.7% sections with failures.
IIRC, last time this was around 13% test failures. Note I haven't changed
anything since that run ;-)
Please apply when you find the time!
Thanks!
Ruben

All failures in the libc++ test suite will be documented here.
-Last run was with Clang (pre-3.0) and GCC 4.6.2 (prerelease) and
- mingw-w64 on x86_64-w64-mingw32.
+Last run was with Clang (pre-3.1) and GCC 4.6.3 (with dw2 exception handling) and
+ mingw-w64 v2.0.3 on i686-w64-mingw32.
-The commands to build and test were (-nodefaultlibs does not work, lots of MinGW related stuff gets left resulting in linker failures):
-TRIPLE=x86_64-w64-mingw32 ./buildit
-TRIPLE=x86_64-w64-mingw32 HEADER_INCLUDE="-I/home/Ruben/libc++/include" LIBS="-L/home/ruben/libc++/lib -lc++ -lsupc++ -lmsvcr100 -Wl,--allow-multiple-definition" PATH=/home/Ruben/libc++/lib:$PATH ./testit > test.log 2>&1
+The following line was added to ./lib/buildit to make a static libc++ library because a DLL requires "declspec(dllexport)" or a .def file:
+ar rcs libc++.a *.o
+I also deleted libc++.dll and libc++.dll.a to make sure libc++ was linked statically to prevent unrelated issues from contaminating the test results.

-Note: Exception catching seems broken in Clang, so any test catching
- exceptions is currently broken. Result will be compared to GCC's result.
- Failing tests only on GCC will be ignored: Clang is the standard in this
- part of the world, and GCC fails on many C++11 constructs in libc++.
Note: Some locale tests may "Need investigating", but I think most problems are
- caused by wrong/unportable locale naming in the tests.
-Note: Thread test results are very different from the last run: failures now
- pass and passes now fail. These results are not to be trusted.
+ caused by wrong/unportable locale naming in the tests.
+Note: Some tests failed to link because "test.exe" was still running when ld.exe
+ tried to link the next test. I left these failures out of the list; they
+ account for about 10-30 failures, and are counted in the total scores below.
+ I reran some of these failures manually and they passed.
+Note: Some tests fail at runtime but pass when run manually. Usage of std::cout
+ segfaults so further investigation is difficult. These also contribute to
+ the failures total, but are left out of the failure list, as the cause is
+ probably not located in that part of libc++, not locatable due to the lack
+ of usable debug info generated by Clang at this time.
