--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> --- Created attachment 41057 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41057&action=edit tentative patch This script tries to rewrite all tests, but that's not entirely supported yet. Known error causes: - PR80219 relative line numbers only working if gcc_{error,warning}_prefix defined - PR80220 relative line numbers don't work when put between braces
