From 4b25b519ae46b283988a1847e56a19b01269b3a4 Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Mon, 18 May 2009 19:24:07 +0200 Subject: bitbake: [parser] Cary a Statement Node through the parsing When parsing we will collect a number of statements that can be evaluated...The plan is to be evaluate things twice (old+new) and then compare the result, it should be the same.
