This removes the _ZNSt12system_errorC* pattern from the GLIBCXX_3.4.11 version, because it doesn't seem to be used at the moment, but inlining changes being tested for PR ipa/58721 cause some new symbols to be added to the library and exported with version GLIBCXX_3.4.11, which obviously shouldn't be getting new symbols now. This happened for Solaris previously, and Rainer disabled the pattern for Solaris: http://gcc.gnu.org/ml/libstdc++/2012-10/msg00070.html This patch does the same for all targets. Tested x86_64-linux, committed to trunk. commit ee702751f19b333766011c6cd16156ce6c76bb69 Author: Jonathan Wakely <jwakely@redhat.com> Date: Fri Mar 14 17:26:26 2014 +0000 PR ipa/58721 * config/abi/pre/gnu.ver (GLIBCXX_3.4.11): Remove unused pattern for _ZNSt12system_errorC* symbols which are not exported on any target.
