Louis Dionne 71d88cebfb [libc++/libc++abi] Automatically detect whether exceptions are enabled ... Instead of detecting it automatically (in libc++) and relying on _LIBCXXABI_NO_EXCEPTIONS being set explicitly (in libc++abi), always detect whether exceptions are enabled automatically. This commit also removes support for specifying -D_LIBCPP_NO_EXCEPTIONS and -D_LIBCXXABI_NO_EXCEPTIONS explicitly -- those should just be inferred from using -fno-exceptions (or an equivalent flag). Allowing both -D_FOO_NO_EXCEPTIONS to be provided explicitly and trying to detect it automatically is just confusing, especially since we did specify it explicitly when building libc++abi. We should have only one way to detect whether exceptions are enabled, but it should be robust.		2020-07-03 14:58:09 -04:00
