[PATCH 4/4] AArch64: Add regmove_costs for Cortex-A57 and A53

2014-09-04 Thread Wilco Dijkstra
This patch adds regmove_costs for Cortex-A57 and A53, and sets the cost of GP2FP/FP2GP higher than memory cost to block the register allocator allocating integer values in FP registers. Overall these patches give 2-3% speedup on SPEC. This passes all regression tests (with this fix https://gcc.
