[PATCH, ARM] Make branch cost a tunable parameter

2011-06-01 Thread Julian Brown
This patch allows the BRANCH_COST macro to be altered for a given target using the ARM backend's tuning infrastructure. It's not easy to reduce the cost to e.g. a single integer or a set of integers (cores may have different branch costing characteristics for ARM vs. Thumb-2 mode for instance, as i
