From 10b29d8cfe60891851817e81b6e705da6c6d4534 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Fri, 9 Apr 2010 10:12:18 +0000 Subject: [PATCH] thin out romcc epilogue and have it call copy_and_run as all the others do. Make sure copy_and_run is called with the right calling convention. Fix up 2 license headers.
