From: Andrew Pinski <pinskia@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r14-364] Improve error message for excess elements in array initializer from {"a"} Date: Sun, 30 Apr 2023 21:49:31 +0000 (GMT) [thread overview] Message-ID: <20230430214931.204C33857712@sourceware.org> (raw) https://gcc.gnu.org/g:d56af02fb1fd6eb50beb8a1689cf646bc567dbfc commit r14-364-gd56af02fb1fd6eb50beb8a1689cf646bc567dbfc Author: Andrew Pinski <apinski@marvell.com> Date: Wed Nov 30 04:02:07 2022 +0000 Improve error message for excess elements in array initializer from {"a"} So char arrays are not the only type that be initialized from {"a"}. We can have wchar_t (L"") and char16_t (u"") types too. So let's print out the type of the array instead of just saying char. Note in the testsuite I used regex . to match '[' and ']' as I could not figure out how many '\' I needed. OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions. gcc/c/ChangeLog: * c-typeck.cc (process_init_element): Print out array type for excessive elements. gcc/testsuite/ChangeLog: * gcc.dg/init-bad-1.c: Update error message. * gcc.dg/init-bad-2.c: Likewise. * gcc.dg/init-bad-3.c: Likewise. * gcc.dg/init-excess-3.c: Likewise. * gcc.dg/pr61096-1.c: Likewise.
