Howard Hinnant 73ab1864ef Marshall Clow reminded me that fallback_malloc.cpp was broken out for testing purposes. We've agreed to simply rename fallback_malloc.cpp to fallback_malloc.ipp. Thanks Marshall.

Howard Hinnant b24c9441d1 One more small optimization: Where possible, for loops that do a search and then try to break out of the loop early, eliminate the attempt to break out of the loop after the last search. And with that, I'm declaring __dynamic_cast done. Though if anyone sees any problems, has suggestions for improvements, or wants to contribute some test cases, that is certainly welcome feedback.

Howard Hinnant 44a2895a03 Comment smithing. Changed some casts from C-style to C++. And added timings to all of the tests.

Howard Hinnant 77fb8ab9f2 I think this is getting close on __dynamic_cast. There's been quite a bit of code rearrangement, renaming, and better commenting. This exercise has exposed and fixed a few more bugs. I've also added several more tests (there's definitely a need for more tests here).

Howard Hinnant 50f7eeec9d 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.

Howard Hinnant b7d59ec6e1 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.

Howard Hinnant af07bfdb67 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.

Nick Lewycky 6fde150697 Add more tests for cxa_guard methods. This includes our first two tests using
actual threads!

There's no build file for libcxxabi, so I'll tell you that I built it with this:
$ g++-4.6 -pthread -std=gnu++0x test_guard.cpp ../src/cxa_guard.o -o test_guard
