Subject: [PATCH] Vector mode addresses
Authentication-results: sourceware.org; auth=none

As a followup of the thread:
http://gcc.gnu.org/ml/gcc/2014-01/msg00206.html

consider the attached patch for submission. It fixes an ICE in case you try to use vector mode addresses and do not have it as mode dependent target hook.
As discussed in the thread adding VECTOR_MODE_P to the target hook is a way to avoid ICE but as Richard S. mentioned it's more general to patch GCC up.

Bootstrapped and tested on x86_64-unknown-linux-gnu.

	* simplify-rtx.c (simplify_subreg): Do not adjust address if memory 
       address has vector mode.


OK to submit?
