Hi all,
This is a much-delayed respin of the patch in response to Richards
feedback at:
http://gcc.gnu.org/ml/gcc-patches/2014-05/msg00068.html
We now let recursion do its magic and just add the cost of the
arithmetic operation on top.
Tested on arm-none-eabi
Ok for trunk?

* config/arm/arm.c (arm_new_rtx_costs, case PLUS, MINUS):
Add cost of alu.arith in simple SImode case.
