From ba2336b3b1ca5cfe1e67dbe37a084c9644a65ac7 Mon Sep 17 00:00:00 2001
From: Chris Liddell <chris.liddell@artifex.com>

Subject: [PATCH] Remove .forcedef, and harden .force* ops more
Remove .forcedef and replace all uses with a direct call to .forceput instead.
Ensure every procedure (named and trasient) that calls .forceput is
executeonly.
Signed-off-by: Baruch Siach <baruch@tkos.co.il>
