From 26f42329caf1dcd4a410de61045208024156169f Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Fri, 17 Jan 2020 09:58:57 -0500 Subject: [PATCH] gdb: remove uses of iterate_over_inferiors in top.c Replace with range-based for loops. gdb/ChangeLog: * top.c (struct qt_args): Remove. (kill_or_detach): Change return type to void, replace `void *` parameter with a proper one. (print_inferior_quit_action): Likewise. (quit_confirm): Use range-based for loop to iterate over inferiors.
