--- Comment #3 from Kostya Serebryany <kcc at gcc dot gnu.org> --- I am very sorry that you are so upset, but the workflow will not change. All changes to sanitizer files (except for GCC-specific tests and make files) have to go to upstream first. If any change goes directly to GCC it will get overwritten by a following merge from upstream. (merge is the wrong name for process actually. The right name would be "copy").
