(forgive my ignorance here) Two general questions: 1. Before doing the merge I test the patch like this: rm -rf */{*/,}libsanitizer && make -j 50 && make -C gcc check-g{cc,++} RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} asan.exp' What should I add to this line to also test x32? 2. Is there any chance to test x32 off the clang tree, so that we keep the upstream tree x32-clean all the time?
