Subject: [PATCH] libstdc++-v3/include/bits/regex_error.h: Avoid warning with -fno-exceptions.
Date: Fri, 11 Sep 2020 12:23:05 +0000	[thread overview]
Message-ID: <1599826987-5240-1-git-send-email-christophe.lyon@linaro.org> (raw)

When building with -fno-exceptions, __GLIBCXX_THROW_OR_ABORT expands to
abort(), causing warnings:
unused parameter '__ecode'
unused parameter '__what'

This patch adds __attribute__((unused)) to avoid them.
