From e0a42ebc0831e3ae18e965cc202b5d6649cc38f2 Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Sat, 22 Jan 2011 12:39:16 +0100 Subject: microblaze: Improve subkc Move code from the helper into the translator. The remaining helper parts can reuse helper_addkc, making it possible to remove helper_subkc entirely. Signed-off-by: Edgar E.
