04461e6012 Since C++ typeinfo objects are currently not guaranteed to be merged at
runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary.  (This is similar to what GNU libstdc++ does
in its default configuration.)  The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.

26b8b75c54 Don't use _Unwind_Backtrace() on ARM as it's currently missing from our libgcc_s. andrew@ has patches to add it, so this can be reverted and sync'd with upstream later. 2013-08-31 08:56:33 +00:00

02e4f2a3a4 Remove __attribute__((__aligned__)) that generates incorrect alignment on compilers that know about SSE. Code left over from old header that thought that 64 bits was the maximum alignment that anything would ever need... 2013-08-07 11:30:04 +00:00

d9e22925e0 Merge libcxxrt c812a07cd2f95c1403baf0bbe0366e7618d1d6d3:
* Don't call the _fast version of the TLS accessor in terminate() or
  unexpected().
  1) TLS may not have been set up yet.
  2) When we're in one of these functions, Really Bad Stuff has
     happened and potentially saving a few cycles really isn't
     important.
* Merge in fixes from FreeBSD trunk to make atomics work with recent
  clang.

d5861eaae8 Import new fix from libcxxrt. This fixes the case where you attempt to rethrow
an exception when you haven't caught one.  This is largely a cosmetic fix, as
(unless you have a very unusual terminate handler installed) it will print a
nice error and then abort, rather than just aborting.

f7cb16572f Merge new version of libcxxrt. This brings in three fixes:
- Don't treat pointers to members as pointers in catch blocks (they're usually
  fat pointers).

- Correctly catch foreign exceptions in catchalls.

- Ensure that a happens-before relationship is established when setting
  terminate handlers in one thread and calling them in another.

c725650d64 Import new version of libcxxrt. Now works correctly with libobjc2 to implement
the unified exception model for Objective-C++.

7a98470824 Import libc++ / libcxxrt into base. Not build by default yet (use
MK_LIBCPLUSPLUS=yes to enable).  This is a work-in-progress.  It works for
me, but is not guaranteed to work for anyone else and may eat your dog.

To build C++ using libc++, add -stdlib=libc++ to your CXX and LD flags.

Bug reports welcome, bug fixes even more welcome...
