Subject: [PATCH 1/4] FRV: Fix VLIW packing constraint violation in entry.S
Date: Mon, 15 Oct 2012 12:43:43 +0100 [thread overview]
Message-ID: <20121015114343.1042.81528.stgit@warthog.procyon.org.uk> (raw)
Fix VLIW packing constraint violation in entry.S:
arch/frv/kernel/entry.S: Assembler messages:
arch/frv/kernel/entry.S:871: Error: VLIW packing constraint violation
When packing CALLL with OR, CALLL must go in the first slot. The instructions
are executed simultaneously, so it doesn't matter which way round they're
packed from that point of view.
