Hi, This simple patch computes and preserves loop nest vector for whole distribution life time. The loop nest will be used multiple times in on-demand data dependence computation. Bootstrap and test on x86_64 and AArch64. Is it OK? Thanks, bin 2017-06-07 Bin Cheng <bin.cheng@arm.com> * tree-loop-distribution.c (loop_nest): New global var. (build_rdg): Use loop directly, rather than loop nest. (pg_add_dependence_edges): Remove loop nest parameter. Use global variable directly. (distribute_loop): Compute global variable loop nest. Update use.
