7d70451b49 Updated the comment about __cxa_uncaught_exceptions. 2019-01-08 04:47:51 +03:00
Andrey Semashev
bf932b4908 Removed the use of __cxa_uncaught_exceptions. 
Travis CI shows linking errors on Linux and OS X when __cxa_uncaught_exceptions
is used to implement uncaught_exceptions. There's probably some library missing,
which should be linked in implicitly by the compiler, or the library indeed
does not export the symbol. In any case, __cxa_get_globals-based implementation
should provide the same effect.

dea6b04157 Added workarounds for gcc < 4.7 on Linux and OpenBSD. 
Apparently, gcc < 4.7 on Linux also don't have __cxa_get_globals
declaration in cxxabi.h. Declare the function ourselves.

Also, on OpenBSD it seems there is no declaration either, and
on that platform the function implementation has no exception
specification, like on FreeBSD. Add a declaration of that platform.

Lastly, changed __cxa_get_globals and _getptd-based implementations
to avoid violating strict aliasing rules. This is still formally UB
to access structure fields like we do, but this is one less reason to
cause miscompilation or compiler warnings.

9f9da9dc9b Limit __cxa_uncaught_exceptions to only since libc++abi 1002 and later. 2019-01-07 13:34:52 +03:00

cdcc50a455 Added an implementation for uncaught_exceptions for libc++abi. 
This should fix compilation errors due to missing declaration of
__cxa_get_globals when compiled against libc++ on Linux.

6f3e6254e7 Only declare __cxa_get_globals on MinGW gcc < 4.7, where it's needed. 
This should work around differences between the function signatures on other
platforms, like FreeBSD, for example.

3cd1885209 Reorganized code and made __cxa_get_globals signature closer to the original. 
This should resolve gcc errors caused by mismatch of the return types of
aur declaration of __cxa_get_globals and the original in cxxabi.h.

Fixes https://github.com/boostorg/core/issues/45.

82957de970 Extracted uncaught_exceptions function from Boost.Log. 
The uncaught_exceptions function is functionally equivalent to
unhandled_exceptions_count in Boost.Log and implements functionality
similar to the same named C++17 standard function. Tests and docs are
also included.

One notable difference from std::uncaught_exceptions is that the return
type is unsigned rather than signed. This is deliberate as uncaught_exceptions
must never return a negative value and unsigned int better documents that.
Theoretically, as a counter, it may also overflow.

e1f070b7b4 Remove anti_op and change the error output 
The new output is no less useful, and not potentially misleading (for example in the case of BOOST_TEST_LT(1, nan) failing, it was not right to say that 1 >= nan).
