From 4f13c1c00be32131845ae50aef788d4f2c652dff Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 21 Dec 2019 11:14:56 -0700 Subject: [PATCH] Make "file" clear TUI source window I noticed that a plain "file" will leave the current source file in the TUI source window. Instead, I think, it should clear the source window. This patch implements this. gdb/ChangeLog 2020-01-19 Tom Tromey * tui/tui-winsource.c (tui_update_source_windows_with_line): Handle case where symtab is null. gdb/testsuite/ChangeLog 2020-01-19 Tom Tromey * gdb.tui/main.exp: Add check for plain "file".
