Subject: [PATCH] c++: Don't quote nothrow in diagnostic
Date: Fri, 23 Sep 2022 14:40:26 -0400 [thread overview]
Message-ID: <20220923184026.379494-1-polacek@redhat.com> (raw)
In <https://gcc.gnu.org/pipermail/gcc-patches/2022-September/602057.html>
Jason noticed that we quote "nothrow" in diagnostics even though it's
not a keyword in C++. Just removing the quotes didn't work because
then -Wformat-diag complains, so this patch replaces it with "no-throw".
Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk?
gcc/cp/ChangeLog:
* constraint.cc (diagnose_trait_expr): Say "no-throw" (without quotes)
rather than "nothrow" in quotes.
gcc/testsuite/ChangeLog:
* g++.dg/cpp2a/concepts-traits3.C: Adjust expected diagnostics.
