[PATCH][AArch64] Improve spill code - swap order in shl pattern

2015-04-27 Thread Wilco Dijkstra
Various instructions are supported as integer operations as well as SIMD on AArch64. When register pressure is high, lra-constraints inserts spill code without taking the allocation class into account, and basically chooses the first available pattern that matches. Since this instruction has the
