This issue is introduced by https://github.com/dmlc/tvm/pull/2605
It is useful to print relay ir after passes for debug. Adding print(ir_pass.pass_debug_print(func, show_meta_data=False))
after ir_pass.fuse_ops
in relay.build_module, sub-functions are printted in reverse order which are diffucult to read.
Also, the place that subfunctions are shown seems strange. Previously subfunctions are printed before the first time they are called. The current way is to print several subfunctions and then call each of them, is this intended?
