From ea63396f6b08f88f1cde827e6cab94cd488f7fa7 Mon Sep 17 00:00:00 2001 From: Jeff Chapman II Date: Thu, 3 Nov 2022 15:47:19 -0400 Subject: libstdc++: add experimental Contracts support This patch adds the library support for the experimental C++ Contracts implementation. This now consists only of a default definition of the violation handler, which users can override through defining their own version. To avoid ABI stability problems with libstdc++.so this is added to a separate -lstdc++exp static library, which the driver knows to add when it sees -fcontracts.
