From 5da01df5b5601cae695cee588547fb9ef0967081 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sun, 22 Jul 2018 10:28:23 -0600 Subject: [PATCH] Remove a VEC from ppc-linux-nat.c This replaces a VEC in ppc-linux-nat.c with a std::vector. gdb/ChangeLog 2019-05-04 Simon Marchi Tom Tromey * ppc-linux-nat.c (thread_points_p): Remove typedef and DEF_VEC. (ppc_threads): Now a std::vector. Now static.
