Hi,
This is a case when ivopts pass makes too many induction variables, exceeding
the number of available registers. If you want to debug it, see
ivopts_global_cost_for_size in tree-ssa-loop-ivopts.c and its callers;
perhaps, the issue is that it fails to account for IVs created in inner loops

Hi guys,
I have a test case (shell sort, see attached) compiled with different
ARM compilers:
GCC-4.6.3, GCC-3.4.6, and ARMCC.
Both ARMCC and GCC-3.4.6 generate quite optimal assembly while GCC-4.6.3
inserts extra load/store instructions compared to the other compilers.
Can the SSA representatio
