--- Comment #1 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nathan Sidwell <nat...@gcc.gnu.org>: https://gcc.gnu.org/g:dd6f588a7b8878d677af51ff4d1c1e3f9f6f40db commit r11-7989-gdd6f588a7b8878d677af51ff4d1c1e3f9f6f40db Author: Nathan Sidwell <nat...@acm.org> Date: Mon Apr 5 07:51:28 2021 -0700 c++: Unneeded export query [PR 99380] This problem got introduced fixing a module numbering problem. When preprocessing a header unit, we don't need to send an EXPORT query unless we're also determining dependencies, or the mapper asked us to. Sadly the testsuite isn't set up to test this kind of subtlety. I manually did that with stdin/stdout. PR c++/99380 gcc/cp/ * module.cc (name_pending_imports): Drop 'atend' parm. Don't query export when not needed. (preprocess_module, preprocessed_module): Adjust.
