> The C++ ABI is not part of the Fuchsia system ABI, nor what we call the "Fuchsia compiler ABI". Different users of C++ are free to use whatever C++ ABI they like. Only the backend ABI independent of language-specific issues is necessary to interoperate with other code on Fuchsia.
Sure enough - but I'm still sort of confused by why the Fuschia Clang target/compiler needs more than one C++ ABI. What is it interoperating with? (GCC doesn't have a Fuschia target implemented, does it? So what's it mean to target the GCC C++ ABI? what is compiling the code that Fuschia is trying to interoperate with when Clang targets Fuschia with a non-default C++ ABI?)
