On Windows, typeids are different between DLLs and EXEs, so comparing
...
type_info* will work for typeids from the same compiled file but fail
for typeids from a DLL and an executable. Among other things, exceptions
are not caught by handlers since can_catch() returns false.
Defining _LIBCXX_DYNAMIC_FALLBACK does not help since can_catch() calls
is_equal() with use_strcmp=false so the string names are not compared.
This patch compares typeids first (cheap) and only they are different
calls strcmp.

libcxxabi contains the runtime support for C++. But, as some folks have
...
realized, it is not complete. It relies on some _Unwind_* functions to be
supplied by the OS. That means it cannot be ported to platforms that don’t
already have an unwinder.
Years ago Apple wrote its own unwinder for MacOSX and iOS. To make libcxxabi
complete, Apple has decided the source code for its unwinder can be contributed
to the open source LLVM libcxxabi project, with a dual licensed under LLVM
and MIT license.
So, I’ve spent some time cleaning up the sources to make them conform with
LLVM style and to conditionalize the sources in a way that should make it
easier to port to other platforms. The sources are in a separate "Unwind"
directory under "src" in libcxxabi.
Background:
Most architectures now use "zero cost" exceptions for C++. The zero cost means
there are no extra instructions executed if no exceptions are thrown. But if
an exception is thrown, the runtime must consult side tables and figure out how
to restore registers and "unwind" from the current stack frame to the catch
clause. That ability to modify the stack frames and cause the thread to resume
in a catch clause with all registers restored properly is the main purpose
of the unwinder.
This unwinder has two levels of API. The high level APIs are the _Unwind_*
functions which the cxa_* exception functions in libcxxabi require. The low
level APIs are the unw_* functions which are an interface defined by the the
old HP libunwind project (which shares no code with this unwinder).

I'd no sooner made the last commit when Matthew Dempsky sent me another test case that led me to yet another closely related test case that the current design could not handle. I've now changed the way forward references are handled completely. It wasn't that much code to change. The demangler, when confronted with a forward reference to a template parameter, now parses things twice. During the second parse, all forward references are remembered from the first parse. Test suite updated with new case.

After a private conversation with Arthur O'Dwyer, and a good night's sleep, I believe this fix is a better fix than what I committed in r184656 yesterday. I've basically moved the checking for '`' from the start of the demangling process to the end of it. In the process I discovered that one of the test cases no longer demangled to the expected string. After further investigation I believe this case to not be a valid mangled string, and so I moved the test case to the 'invalid cases'. The reason I believe it is invalid is that it should use T_ instead of T0_ to index the template parameter.

Two changes: 1) I still didn't have the ABI correct to match the gcc-4.2 std::string under the exception classes. I think the changes to stdexcept.cpp have got that down now. 2) On Apple platforms I'm seeing visibility bugs in applications with respect to type_info's being hidden. This is causing dynamic_cast to malfunction because there are multiple type_info's running around for one type within an application, making dynamic_cast believe that one type is actually multiple types. As a stop gap measure I'm trying to detect this error, print out an error message, but continue with the most likely desired result. This is all under __APPLE__. This behavior can be expanded to other platforms if desired.

I've added Apple-only behavior that looks for libstdc++ in the same process and if found, checks the string stored in <stdexcept> exception objects to see if it is the gcc empty string singleton before manipulating the reference count. This is done so that if such an exception is created with a zero-length string in libstdc++, libc++abi won't try to delete the memory. This is part of a ongoing process to make libc++ exceptions ABI-compatible with libstdc++-4.2 exceptions, to the point that each library can catch exceptions thrown by the other. If other parties would also like this behavior, the #if __APPLE__ can be broadened.

Andrew Morrow: Mainline clang seems to have recently become more strict about the
...
consistent application of visibility attributes, which causes some new
breakage in libcxxabi:
In file included from src/libcxxabi/src/cxa_default_handlers.cpp:19:
src/libcxxabi/src/private_typeinfo.h:123:23: error: visibility does
not match previous declaration
class __attribute__ ((__visibility__(default))) __class_type_info
^
src/libcxxabi/src/private_typeinfo.h:19:13: note: previous attribute is here
#pragma GCC visibility push(hidden)
^
1 error generated.
The forward declaration of __class_type_info is picking up hidden
visibility from the #pragma, which conflicts with the default
visibility applied when the class is later fully declared. I'm
assuming that the full declaration has it right (and that the
diagnostic is correct), so the attached patch applies the default
visibility attribute to the forward declaration.

I've moved __cxa_terminate_handler, __cxa_unexpected_handler and __cxa_new_handler from the public header cxxabi.h into the private header cxa_handlers.hpp. During this move I've also moved them from namespace __cxxabiapple into the global namespace. They are, and have always been extern C and so the namespace (or lack of it) does not affect their ABI. In general external clients should not reference these symbols. They are atomic variables and will be changing into C++11 atomic variables in the future. However for those few clients who really need access to them, their name, mangling, size, alignment and layout will remain stable. You just may need your own declaration of them. Include guards have been added to the private header cxa_exception.hpp. The private header cxa_default_handlers.hpp has been removed and the default handlers are now file-static. Include guards have been added to the private header cxa_handlers.hpp.

I had originally made the handler function pointers a static internal detail, not accessible to the outside world. I did this because they must be accessed in a thread-safe manner, and the library provides thread-safe getters and setters for these. However I am at least temporarily making them public and giving them the Apple-extension names. In the future these may disappear again, and I think that would probably be a good idea.

Removing a TODO: can_catch is fundamentally different than search_above_dst. can_catch is looking for an unamiguous public base class of a specific type, but at any address. search_above_dst is looking for an unambiguous public base class of a specific type, *and* at a specific address. Additionally can_catch is run for all types. search_above_dst is only run on class types. So these are only superficially similar. Not similar enough for resuse, at least without making the code unreadable.

Add a descriptive name for a constant. Also I'm at least temporarily waging war on throw specs, both old and new style. Except where we have already publicly exposed the throw spec, I'm getting rid of them. They may come back later. But they seem somewhat prone to cyclic dependencies here. The throw spec implies compiler generated code that this library has to jump to during stack unwinding. I'd like to minimize the possiblity that the code used to properly make that jump is itself creating such jumps.

By changing all of the throw() specs to noexcept I've been able to compile and link all of the source files into a dylib.

A lot of the code in cxa_exception.cpp depends on __cxa_get_globals_fast() returning null if __cxa_get_globals() hasn't been called yet. However it doesn't reliably do that, at least on OS X if __cxa_get_globals_fast() is called prior to pthread_key_create() running. Our choice is to either limit our use of __cxa_get_globals_fast() more than we have, or to have __cxa_get_globals_fast() initialize with pthread_key_create() if necessary. I chose the latter, and replaced pthread_once with a C++11 local static (which should do the same thing).

I kept getting confused among the __cxa_exception*, the _Unwind_Exception* and the void* to the thrown object.

Add __shim_type_info which fits below std::type_info and above all of the other type_info-derived classes. This is where all of the virtual functions that serve as details of the inner-workings of type_info will live (safely hidden from public view). All type_info objects will be safely down-castable to __shim_type_info, so as to access implementation detail virtual functions. Also temporarily add some print/display statements to each type_info-derived class. This is in support of the continuing development on the personality function.

A bug fix involving the updating of path_dst_ptr_to_static_ptr. Some minor code rearrangement optimizations (putting most likely 'if' first in an if-else series. And some major optimizations which involve stopping the search prior to an exhaustive walk over the entire tree. Some of these stops are because an ambiguity is detected earlier. And some of the short circuiting is due to the information from the bits __diamond_shaped_mask and __non_diamond_repeat_mask. The stress test checked in last night is now about 28% faster for the B<Width/2, Depth> -O3 case. I'm still playing with some more optimization possibilities but I'm not sure they will play out.

Enclosed is a stress test for dynamic_cast. It stresses both libc++abi, and clang itself. It creates a ridiculously large class hierarchy using variadic templates. You can specify both the width and depth of the class hierarchy. And you can specify whether the cast is to the actual run time type, or to an intermediate layer in the class. About 1/3 of the time I compile this, it crashes the compiler. There seems to be an uninitialized area of memory, and I'm probably blowing past an assumption on class hierarchy size within clang (and understandably so). I can get it work most of the time with a class hierarchy width of 20 and a depth of 7. I'm making timings with both -O3 and -Os, using both cast to root and cast to intermediate, on both libc++abi, and gcc's dynamic_cast. I've put the results in a comment/table at the bottom of the test.

Put debug print statments under a flag so that I can get a first glimpse at performance. So far I haven't noticed any performance difference between this new __dynamic_cast and gcc's implementation. But I've barely started looking. Also adding a couple of tests which come straight out of the standard.

Fixed a couple of bugs, updated many comments, and am including a comprehensive test for when there are only 3 types in place. I need to do something similar for 4 and maybe more types, but I'm not sure how comprehensive I can make the test at 4 and above types.

Initial implementaiton of __dynamic_cast. There is still lots of debugging code in here that needs to be stripped out. And many, many unit tests need to be written. And comments and probably code cleanliness needs to be improved. But I *think* the basic algorithm is sound. There also may still be some oportunities for algorithm optimization, I'm not positive.

This is a transitory commit for __dynamic_cast. It contains debugging statements that are not intended to be in the finished product. However some of the dubbing statements themselves contain important documentation such as how to navigate a __class_type_info hierarchy, documenting object offset and inheritance access. The intention is that this debugging code will migrate into both actual code and comments. And capturing it here so that there is no chance this stuff will be lost.

First brush with testing __gxx_personality_v0 reveals there is still a long way to go. But my understanding of what it is supposed to do continues to improve. I am currently contemplating whether I need to implement typeinfo before completing __gxx_personality_v0 in order to get matching catch handlers correct.

Correct comment regarding members of __cxa_dependent_exception. Actually it is useful to disguise a __cxa_dependent_exception as a __cxa_exception by filling in most (not all) of these members at __cxa_dependent_exception construction time. That way most routines don't have to care which kind of exception they have.

__gxx_personality_v0 update. This is completely untested code. But my brain is scrambled and I wanted to get it checked in. Code review from anyone who knows anything at all about personality functions would be much appreciated. What is in here is borrowed heavily from llvm/examples/ExceptionDemo/ExceptionDemo.cpp. There are some calls to abort() that should probably be changed to return an error code instead. There may be encodings under readEncodedPointer that need to be implemented. And my handling of type_info is almost a complete guess.

Substituted std::get_terminate() for direct access to the handler function pointer (which is now a static in cxa_handlers.cpp). This has the advantage of going through the atomic API and so is less likely to cause a data race. Ditto for unexpected.

terminate, unexpected and new handlers. If terminating while an exception is unwinding, an attempt is made to print out the what() string if the exception is derived from std::exception. __terminate(handler) and __unexpected(handler) helpers are present in anticipation of other parts of libc++abi needing to call these interfaces with custom handlers.
