From 14577312211e25024ffd90bbded44b021877fc59 Mon Sep 17 00:00:00 2001 From: Andy Polyakov Date: Mon, 22 Feb 2016 17:39:00 +0100 Subject: [PATCH] poly1305/asm/poly1305-armv4.pl: replace ambiguous instruction. Different assembler versions disagree on how to interpret #-1 as argument to vmov.i64, as 0xffffffffffffffff or 0x00000000ffffffff. So replace it with something they can't disagree on.
