re PR rtl-optimization/26847 (Missed optimization in simplify_plus_minus)
2006-09-05 Paolo Bonzini <bonzini@gnu.org>
PR rtl-optimization/26847
* simplify-rtx.c (struct simplify_plus_minus_op_data): Remove ix.
(simplify_plus_minus_op_data_cmp): For REGs, break ties on the regno.
(simplify_plus_minus): Count n_constants while filling ops. Replace
qsort with insertion sort. Before going through the array to simplify
pairs, sort it. Delay early exit until after the first sort, exiting
only if no swaps occurred. Simplify pairs in reversed order, without
special-casing the first iteration. Pack ops after simplifying pairs.
