--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:245e40af4fab5b7cf40fb310591a879355775971 commit r10-6335-g245e40af4fab5b7cf40fb310591a879355775971 Author: Jason Merrill <ja...@redhat.com> Date: Tue Jan 28 17:41:05 2020 -0500 c++: Fix attributes with lambda and trailing return type. My fix for 60503 fixed handling of C++11 attributes following the lambda-declarator. My patch for 89640 re-added support for GNU attributes, but attributes after the trailing return type were parsed as applying to the return type rather than to the function. This patch adjusts parsing of a trailing-return-type to ignore GNU attributes at the end of the declaration so that they will be applied to the declaration as a whole. I also considered parsing the attributes between the closing paren and the trailing-return-type, and tried a variety of approaches to implementing that, but I think it's better to stick with the documented rule that "An attribute specifier list may appear immediately before the comma, '=' or semicolon terminating the declaration of an identifier...." Anyone disagree? Meanwhile, C++ committee discussion about the lack of any way to apply attributes to a lambda op() seems to have concluded that they should go between the introducer and declarator, so I've implemented that as well.
