--- Comment #6 from Kostya Serebryany <kcc at gcc dot gnu.org> --- I am not at war with anyone and if I am, I give up and surrender. But whoever wants the sanitizers to work on SPARC [s]he will have to work with us upstream. We can not fix build failures on SPARC upstream because we don't have access to SPARC machines and there is no public buildbot with SPARC. If no one needs sanitizers on SPARC and all you care about is that GCC builds on SPARC, just disable the sanitizers for SPARC. This is my last response here. For constructive discussion please start sending patches upstream.
