--- Comment #4 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:c33ec196aa713c62d73907dc8f9e57d7ab2e4e4b commit r12-1100-gc33ec196aa713c62d73907dc8f9e57d7ab2e4e4b Author: Matthias Kretz <kr...@kde.org> Date: Thu May 27 17:25:37 2021 +0200 c++: Output less irrelevant info for function template decl [PR100716] Ensure dump_template_decl for function templates never prints template parameters after the function name (it did with -fno-pretty-templates) and skip output of irrelevant & confusing "[with T = T]" in dump_substitution. gcc/cp/ChangeLog: PR c++/100716 * error.c (dump_template_bindings): Include code to print "[with" and ']', conditional on whether anything is printed at all. This is tied to whether a semicolon is needed to separate multiple template parameters. If the template argument repeats the template parameter (T = T), then skip the parameter. (dump_substitution): Moved code to print "[with" and ']' to dump_template_bindings. (dump_function_decl): Partial revert of PR50828, which masked TFF_TEMPLATE_NAME for all of dump_function_decl. Now TFF_TEMPLATE_NAME is masked for the scope of the function and only carries through to dump_function_name. (dump_function_name): Avoid calling dump_template_parms if TFF_TEMPLATE_NAME is set. gcc/testsuite/ChangeLog: PR c++/100716 * g++.dg/diagnostic/pr100716.C: New test. * g++.dg/diagnostic/pr100716-1.C: Same test with -fno-pretty-templates.
