--- Comment #12 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Florian Weimer <f...@gcc.gnu.org>: https://gcc.gnu.org/g:ff9efa3fc48baa1dee7ed376c25ecfcfbc28d35c commit r14-6038-gff9efa3fc48baa1dee7ed376c25ecfcfbc28d35c Author: Florian Weimer <fwei...@redhat.com> Date: Fri Dec 1 08:10:13 2023 +0100 c: Add new -Wdeclaration-missing-parameter-type permerror This used to be a warning, enabled by default, without its own option. A subsequent change could improve diagnostics and provide spelling hints for declarations like âvoid function (int32t);â. gcc/c-family/ * c.opt (Wdeclaration-missing-parameter-type): New. gcc/c/ChangeLog: PR other/44209 * c-decl.cc (grokparms): Issue permerror for OPT_Wdeclaration_missing_parameter_type instead of a pedwarn. gcc/ChangeLog: * doc/invoke.texi (Warning Options): Document -Wdeclaration-missing-parameter-type. gcc/testsuite/ChangeLog: * gcc.dg/permerror-default.c (missing_parameter_type): Expect error. * gcc.dg/permerror-fpermissive.c (missing_parameter_type): Expect -Wdeclaration-missing-parameter-type warning. * gcc.dg/permerror-gnu89-nopermissive.c (missing_parameter_type): Expect -Wdeclaration-missing-parameter-type error. * gcc.dg/permerror-gnu89-pedantic.c (missing_parameter_type): Likewise. * gcc.dg/permerror-gnu89.c (missing_parameter_type): Expect -Wdeclaration-missing-parameter-type warning. * gcc.dg/permerror-noerror.c: Add -Wno-error=declaration-missing-parameter-type to build flags. (missing_parameter_type): Expect -Wdeclaration-missing-parameter-type warning. * gcc.dg/permerror-nowarning.c: Build with -Wno-declaration-missing-parameter-type. Remove previously expected warning. * gcc.dg/permerror-fpermissive-nowarning.c: Likewise. * gcc.dg/permerror-pedantic.c (missing_parameter_type): Expect -Wdeclaration-missing-parameter-type error. * gcc.dg/permerror-system.c (missing_parameter_type): Likewise.
