--- Comment #3 from Matthias Kretz (Vir) <kretz at kde dot org> --- Created attachment 50877 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50877&action=edit proposed patch 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. --- gcc/cp/error.c | 59 +++++++++++++++----- gcc/testsuite/g++.dg/diagnostic/pr100716-1.C | 54 ++++++++++++++++++ gcc/testsuite/g++.dg/diagnostic/pr100716.C | 54 ++++++++++++++++++ 3 files changed, 152 insertions(+), 15 deletions(-) create mode 100644 gcc/testsuite/g++.dg/diagnostic/pr100716-1.C create mode 100644 gcc/testsuite/g++.dg/diagnostic/pr100716.C
