--- Comment #13 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-8 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:283c218a4846075c549f0215d6883e577b26e845 commit r8-10726-g283c218a4846075c549f0215d6883e577b26e845 Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Jan 13 11:03:58 2021 +0000 libstdc++: Fix clang analyzer suppression [PR 98605] The fix for PR libstdc++/82481 should only have applied for targets where _GLIBCXX_HAVE_TLS is defined. Because it was also done for non-TLS targets, it isn't possible to use clang's analyzers on non-TLS targets if the code uses <mutex>. This fixes it by using a NOLINT comment on the relevant line instead of testing #ifdef __clang_analyzer__ and compiling different code when analyzing. I'm not actually able to reproduce the analyzer warning with the tools from Clang 10.0.1 so I'm not going to try to make the suppression more specific with NOLINTNEXTLINE(clang-analyzer-code.StackAddressEscape). libstdc++-v3/ChangeLog: PR libstdc++/98605 * include/std/mutex (call_once): Use NOLINT to suppress clang analyzer warnings. (cherry picked from commit 8d3636923a309074eb19240ebaa30c1a0801eaaf)
