From a7f67bdf2c9f24509b8e81e0f35573b611987c80 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Wed, 12 Jul 2006 15:35:54 +1000 Subject: [POWERPC] Constify & voidify get_property() Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. powerpc core changes.
