From 8419ee5331d5b3253d2bfe1a039f12a167292dfc Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sun, 20 May 2018 20:48:44 -0600 Subject: [PATCH] Move the subfile stack to buildsym_compunit This moves the global subfile_stack to be a member of buildsym_compunit. It also change this to be a std::vector, which simplifies the code. gdb/ChangeLog 2018-07-16 Tom Tromey * buildsym.h (push_subfile, pop_subfile): Update declarations. * buildsym.c (struct buildsym_compunit) : New member.
