...ly unwind through the code. The only ways to prevent exceptions from being propagated are to explicitly catch them, or to use something like a C++ exception specifier so that the personality function will explicitly block exception propagation. In this example, given that doThing is not marked as noexcept, we will emit unwind tables that explicitly allow unwinding through f; however, when the unwinder tries to unwind into the next stack frame it will find that there is no unwind record. Depending on how lazy we are in defining the PC ranges in the unwind table, this will either cause stack corrupti...

...speaking, the less the compiler can prove about a program, the less aggressive it can be with optimizations. If it doesn't know what the control flow will exactly look like, it can't do certain transformations. Exceptions add a conditional goto from every single function call (without good noexcept hygiene, which practically no program has), to the exception handler or cleanup landing pad (whether the exception handler is written in the code explicitly or not, something has to run the destructors of objects that are going out of scope.) Worse, inlining doesn't really save you, because any...

Hi All, I recently committed <filesystem> to trunk. I wanted to bring attention to some quirks it currently has. First, it's been put in a separate library, libc++fs, for now. Users are responsible for linking the library when they use filesystem. Second, it should still not be considered ABI stable. Vendors should be aware of this before shipping it. Hopefully all the standard and
