Marshall Clow e604469e5c Patch by GM: apparently '__value' (two underscores) is a special name in Visual Studio, so rename the private method in <regex> with that name. GM's patch used '___value' (three underscores), but I changed that to '__regex_traits_value' because I've been burned in the past by identifiers that appear identical but are not.

Howard Hinnant 58af7e177c r192075 broke the buildbot at
http://lab.llvm.org:8013/builders/libcxx_clang-x86_64-darwin11-RA

lit.py: <string>:230: note: inferred use_system_lib as: False
lit.py: <string>:247: fatal: C++ ABI setting None unsupported for tests

cxx_abi is geting set to None, and the lit script errors out shortly after
that.  This patch changes the default of cxx_abi from None to 'libcxxabi'.
This is likely not the right way to fix this problem.  However it gets the
buildbot running again.  Improvements to this fix are welcome.

Peter Collingbourne 8b9c5d1ac7 Silence the unused function warning in exception.cpp.
Rather than try to protect the function behind a precise,
ever-changing #if expression, just inline it into every caller.

Peter Collingbourne 3b5d969293 Implement std::exception_ptr under libsupc++.
libsupc++ does not implement the dependent EH ABI and the
functionality it uses to implement std::exception_ptr (which it
declares as an alias of std::__exception_ptr::exception_ptr) is not
directly exported to clients. So we have little choice but to hijack
std::__exception_ptr::exception_ptr's (which fortunately has the
same layout as our std::exception_ptr) copy constructor, assignment
operator and destructor (which are part of its stable ABI), and its
rethrow_exception(std::__exception_ptr::exception_ptr) function.

Also, remove some out of date comments.

Peter Collingbourne 26dd09e57f Make it possible to link against libstdc++ as well as libsupc++ with CMake.
Linking against libstdc++, rather than libsupc++, is probably better
for people who need to link against clients of libstdc++.  Because
libsupc++ is provided only as a static library, its globals are not
shared between the static library and the copy linked into libstdc++.
This has been found to cause at least one test failure.

This also removes a number of symbols which were multiply defined
between libstdc++ and libc++, only when linking with libstdc++.

Peter Collingbourne 926aa5f4f2 Eliminate more symbols multiply defined between libsupc++ and libc++.
The remaining multiple definitions were flushed out by attempting to
link libsupc++ and libc++ into the same executable with --whole-archive,
e.g.

clang++ -I../llvm/projects/libcxx/include -nodefaultlibs -Wl,--whole-archive lib/libc++.a /usr/lib/gcc/x86_64-linux-gnu/4.6/libsupc++.a -Wl,--no-whole-archive -lgcc -lgcc_s -lc -lpthread -lrt

(The same technique was used to flush out multiple definitions in
libstdc++.)

Howard Hinnant 4e07b5b955 G M: Attached is a patch for libcxx's cmake file.
I've changed it so we don't set highest level warnings (all) for MSVC when building projects using cmake and instead leave the default. That's /W4 on my machine and seems to be ok.
 
With all warnings on for msvc, we see literally thousands of warnings. 99.99% aren't relevant and just obscure the ones that are.
I think the user can still override things if they want something different from the command line when using cmake.

Howard Hinnant a942f2ffd7 G M: The attached patch is for libcxx's new.cpp and __config files. The patch's intent is to make new.cpp compile using MS's cl.exe compiler without changing the meaning of anything for any other compiler.
The issue this patch seeks to address is that MS's compiler (cl.exe) doesn't support the __attribute__((__weak__)) or __atribute__((__visibility__("default")) syntax; so a solution must be found where cl.exe doesn't see this syntax.

This patch seeks to solve this problem by changing code patterned like this:
__attribute__((__weak__, __visibility__("default")))
void* operator new(size_t size, const std::nothrow_t&) _NOEXCEPT { /*snip*/; return p; }

to code like this:
_LIBCPP_WEAK
void* operator new(size_t size, const std::nothrow_t&) _NOEXCEPT { return p; }

Howard:  Thanks for all the comments regarding the default visibility
tag on the definition.  I agree it isn't needed, and that there are lots
of other places where it is missing.  That being said, I'm not wanting
to rock the boat on that issue right now.  So I've added it back to the
definition via _LIBCPP_FUNC_VIS.  A later pass dedicated just to this
issue can bring things in to a consistent state one way or the other. 
Note that we do not want to have the exact same attributes on the
declaration and defintion in this case.  The declaration should not be
marked weak, whereas the definition should (which is what G M's patch
did). I've fully tested on OS X to ensure that the resultant attribute
syntax actually works.

Howard Hinnant 79710108a4 G M: A small patch to fix a couple of warnings in stdexcept.cpp for cl.exe which does not support #pragma visibility.
llvm-svn: 191988
2013-10-04 22:12:59 +00:00
Howard Hinnant 3af48ef76e G M: Changes all references to "x inline" to "inline x" where x = _libcpp_always_inline or _libcpp_inline_visibility macros.
The patch touches these files:

locale
array
deque
new
string
utility
vector
__bit_reference
__split_buffer
locale_win32.h
 
There is no intended functionality change and it is expected that reversing the position of the inline keyword with regard to the other keywords does not change the meaning of anything, least not for apple/Linux etc.
 
It is intended to make libcxx more consistent with itself and to prevent the 1000 or so
"inline.cpp(3) : warning C4141: 'inline' : used more than once" warnings that MS's cl.exe compiler emits without this patch, i.e. if inline is not the first keyword before a function name etc.
 
Prefer "inline [other inline related keyword]" over "[other related keyword] inline".
After this patch, libcxx should be consistent to this pattern.
