--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:3a2fa2e819d4714cecf5048eda2b7e52ba9e3cdd commit r11-8490-g3a2fa2e819d4714cecf5048eda2b7e52ba9e3cdd Author: Jakub Jelinek <ja...@redhat.com> Date: Thu May 20 09:09:07 2021 +0200 libcpp: Fix up -fdirectives-only handling of // comments on last line not terminated with newline [PR100646] As can be seen on the testcases, before the -fdirectives-only preprocessing rewrite the preprocessor would assume // comments are terminated by the end of file even when newline wasn't there, but now we error out. The following patch restores the previous behavior. 2021-05-20 Jakub Jelinek <ja...@redhat.com> PR preprocessor/100646 * lex.c (cpp_directive_only_process): Treat end of file as termination for !is_block comments. * gcc.dg/cpp/pr100646-1.c: New test. * gcc.dg/cpp/pr100646-2.c: New test.
