From e823b6d7e616b8338b5c2690f0e15e8b1b10b1c7 Mon Sep 17 00:00:00 2001 From: Louis Dionne Date: Thu, 29 Nov 2018 19:44:57 +0000 Subject: [libcxx] Remove bad_array_length Summary: std::bad_array_length was added by n3467, but this never made it into C++. This commit removes the definition of std::bad_array_length from the headers AND from the shared library. See the comments in the ABI changelog for details about the ABI implications of this change.

Since there are no plans to standardize this facility it is being removed. +- Starting with LLVM 8.0.0, std::bad_array_length has been removed from the + library. std::bad_array_length was a feature proposed for C++14 alongside + std::dynarray, but it never actually made it into the C++ Standard. There + are no plans to standardize this feature at this time. Formally speaking, + this removal constitutes an ABI break because the symbols were shipped in + the shared library. However, on macOS systems, the feature was not usable + because it was hidden behind availability annotations. We do not expect + any actual breakage to happen from this change. -- cgit v1.2.3
