From a57aa11191617754c8d43b3eb6a2576e970a0668 Mon Sep 17 00:00:00 2001 From: Patrick Palka Date: Sat, 23 May 2020 15:25:40 -0400 Subject: [PATCH] libstdc++: Compile PR93978 testcase with -Wall Now that the frontend issue PR c++/94038 is thoroughly fixed, the testcase for PR93978 no longer fails to compile with -O -Wall, so add -Wall to the testcase's compile flags to help ensure we don't regress here. libstdc++-v3/ChangeLog: PR libstdc++/93978 * testsuite/std/ranges/adaptors/93978.cc: Add -Wall to dg-additional-options.
