From 89055eaa122ceb99ae20bfe10d028da2ca7fee83 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Mon, 23 Jul 2018 19:51:58 -0600 Subject: [PATCH] Remove a VEC from aarch64-tdep.c This removes a VEC from aarch64-tdep.c, replacing it with a std::vector. gdb/ChangeLog 2019-05-04 Tom Tromey * aarch64-tdep.c (stack_item_t): Remove typedef and DEF_VEC.
