r243067 - in /branches/ARM/sve-branch/gcc: tree...


Author: rsandifo
Date: Wed Nov 30 19:08:40 2016
New Revision: 243067

URL: https://gcc.gnu.org/viewcvs?rev=243067&root=gcc&view=rev
Log:
Reuse results of vect_create_addr_base_for_vector_ref

[Branch only patch -- not intended for trunk in its current state]

At one point we'd seen GCC insert excessive numbers of duplicate
address bases that it wasn't able to clean up later.  This may
be useful for consecutive accesses but I think was mostly important
for gathers and scatters.
