From b9a5ce3cae2f6d04c521204004a36be46656ec7b Mon Sep 17 00:00:00 2001 From: Takashi Ohmasa Date: Fri, 19 Oct 2007 13:59:15 +0100 Subject: [PATCH] [ARM] 4630/1: Fix the vector stride of the double vector instruction. The vector stride of the double-precision vector instructions must be changed to 1-2 from even 2-4, because the double registers numbering has been changed to 0-15 from even 0-30 by 1356c1948da967bc1d4c663762bfe21dfcec4b2f commit.
