Message-Id: <1467127337-11135-3-git-send-email-kieran@bingham.xyz> Date: Tue, 28 Jun 2016 16:22:13 +0100 From: Kieran Bingham <kieran@...uared.org.uk> To: akpm@...ux-foundation.org, corbet@....net, jan.kiszka@...mens.com, kieran@...uared.org.uk Cc: osandov@...com, n.borisov.lkml@...il.com, linux-doc@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/6] scripts/gdb: rebuild constants.py on dependancy change The autogenerated constants.py file was only being built on the initial call, and if the constants.py.in file changed. As we are utilising the CPP hooks, we can successfully use the call if_changed_dep rules to determine when to rebuild the file based on it's inclusions.
