From: Tom Tromey Date: Sun, 7 Apr 2019 22:31:01 +0000 (-0600) Subject: Use std::list for remote_notif_state::notif_queue X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=97dfbaddad2b5acf3dd9f2c3e0135b89bde1cbf8;p=binutils-gdb.git Use std::list for remote_notif_state::notif_queue This changes remote_notif_state::notif_queue to be a std::list and updates all the uses. gdb/ChangeLog 2019-04-19 Tom Tromey * remote.c (remote_target): Use delete. * remote-notif.h: Include , not "common/queue.h". (notif_client_p): Remove typedef. (remote_notif_state): Add constructor, destructor, initializer. : Now a std::list. (remote_notif_state_xfree): Don't declare. * remote-notif.c (remote_notif_process, handle_notification) (remote_notif_state_allocate): Update.
