About X86 Instruction Set

Hi,I run the following code :

...
target = "llvm -mcpu=core-avx2"
with tvm.transform.PassContext(opt_level=3):
    lib = relay.build(mod, target=target, params=params)
    lib.export_library(args.output_file)
...
lib = tvm.runtime.load_module(args.output_file)
dev = tvm.device(str(target), 0)
module = graph_executor.GraphModule(lib["default"](dev))

I want to know if my machine supports avx512, tvm use avx2 or avx512 when I load avx2 module using above code and run model benchmark, thank you !
