[PATCH][AArch64] Improve Cortex-A53 scheduling of int/fp transfers

2017-01-10 Thread Wilco Dijkstra
My previous change to the Cortex-A53 scheduler resulted in a 13% regression on a proprietary benchmark. This turned out to be due to non-optimal scheduling of int to float conversions. This patch separates int to FP transfers from int to float conversions based on experiments to determine the b
