--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- So current things that are known to be used a lot (wrongly): * `dg-run` should be replaced with `dg-do run` (this has showed up more than you think and even in new code; I just happened to have this typo too). * `*.c` files under the `g++.*` testsuite (not the c-c++-common ones where it is acceptable). This is definitely happening: find g++.dg -name "*.c" g++.dg/abi/empty12a.c ... many are not actually being run in first place. * white space after `compile`, `run`, etc. in dg-do. Sam can add what else he has found.
