X-Git-Tag: releases/gcc-10.5.0~33 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f0f8cb2a9f6ec5fdfebb0ee15064133d36a91d64;p=thirdparty%2Fgcc.git libstdc++: include/bits/regex_error.h: Avoid warning with -fno-exceptions. 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. 2020-09-11 Torbjörn SVENSSON Christophe Lyon libstdc++-v3/ * include/bits/regex_error.h: Avoid warning with -fno-exceptions.
