The Darwin toolchain constructor was assuming that all Darwin triples would
have an OS string starting with "darwin".  Triples starting with "macosx"
would misinterpret the version number, and "ios" triples would completely
miss the version number (or worse) because the OS name is not 6 characters
long.  We lose some sanity checking of triple strings here, since the
Triple.getOSVersion function doesn't do all the checking that the previous
code did, but this still seems like a step in the right direction.

This class is used to represent SubRegIndex instances instead of the raw
Record pointers that were used before.

No functional change intended.

Excellent suggestion from Ben Kramer.

Back the optimization down from -O3 to -Os.  I'm getting an unexplained crasher on -O3.  I've looked for a libc++abi bug and can't find one.  I'm suspecting clang optimizer bug.  But I don't have a good test case at the moment.  Deferring investigation on this for now as I will soon be developing more and smaller tests.

llvm-svn: 149414

Drop the stress a notch on dynamic_cast_stress.cpp.  Otherwise it occasionally causes clang to crash.  Put a noexcept(false) on a throwing destructor in test_vector1.cpp.  The test now passes for both C++03 and C++11 modes.  Add testit script.  All tests are now PASSING :-)

now that this handles the release / retain calls.

Adds a regression test for that bug (which is a compile-time
regression) and for the last two changes to the IntrusiveRefCntPtr,
especially tests for the memory leak due to copy construction of the
ref-counted object and ensuring that the traits are used for release /
retain calls.

Have the default unexpected/terminate handler output *demangled* names for the type of exception instead of the mangled name.

(Since this is syntax only, might be a good candidate for turning into a
compiler warning.)

Revert r149359.  This was a hack to a problem with an easy workaround, and it doesn't feel like general solution.

A separate unreachable message will make it easier to debug if either of the
unreachables is reached.

Patch by Niels Grewe!

llvm-svn: 149401

Found and fixed a bug in __cxa_call_unexpected.  If the unexpected_handler rethrows the same exception then needed information gets overwritten in the original exception header.  Therefore save it locally before executing the unexpected_handler.

__has_builtin

in an empty file, as we were overwriting the EOF token.  Overwriting an arbitrary token
never seems like a good idea in the error case.  This fixes a bug reported on the GCC
list :)

This commit provides a new default summary for Objective-C boolean variables, which shows YES or NO instead of the character value. A new category named objc is added to contain this summary provider. Any future Objective-C related formatters would probably fit here

llvm-svn: 149388

This fixes the case where Clang would output:
 error: format specifies type 'wchar_t *' (aka 'wchar_t *')

ArgTypeResult::getRepresentativeTypeName needs to take into account
that wchar_t can be a built-in type (as opposed to in C, where it is a
typedef).

Such a dead code elimination can remove redundant stores to arrays. It can also
eliminate calculations where the results are stored to memory but where they are
overwritten before ever being read. It may also fix bugs like:

This commit just adds a sceleton without any functionality.

If anybody is interested to learn about polyhedral optimizations this would be
a good task. Well definined, self contained and pretty simple. Ping me if you
want to start and you need some pointers to get going.
