References: <4C18F225.2040509@codesourcery.com> <4C227243.9080104@codesourcery.com>

The attached patch tunes code hoisting parameter gcse-unrestricted-cost for ARM. It is provides a small (~0.3%), but measurable size reduction to use a bit lesser cost cutoff for ARM PIC.

Tuning was done on SPEC2K benchmarks.

OK to check in?

Thank you,
