From e6de7069def0fabe3388d3bd078a3e575d4105bf Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sun, 20 Mar 2011 19:34:05 +0000 Subject: [PATCH] BUILD: add -MMD to iasl cpp call Right now there are no dependency rules for compiling dsdt.asl. If ACPI code includes asl files, the dsdt isn't recompiled if any of those file is changed. Add the flags to the preprocessor call to have it generate the neccessary dependency rule.
