[Qemu-devel] [PATCH 10/25] x86: split condition code and shift templates


From: Blue Swirl
Subject: [Qemu-devel] [PATCH 10/25] x86: split condition code and shift templates
Date: Sat, 9 Jun 2012 16:19:06 +0000

Move shift templates from helper_template.h to
shift_helper_template.h and the condition code helpers
to cc_helper_template.h.
