[BUG][CuTe DSL] crd2idx call may cause a floating point exception crash

[alexwl]

Describe the bug When calling cute.crd2idx with arguments in the wrong order (layout, coord) instead of the correct (coord, layout), the program crashes with Floating point exception (core dumped) rather than raising a proper Python exception.

Steps/Code to reproduce bug

import cutlass.cute as cute
@cute.jit
def crash():
    layout = cute.make_layout((2, 2))
    coord = (0, 1) 
    idx = cute.crd2idx(layout, coord)
crash()

Environment details : CuTe DSL version: nvidia-cutlass-dsl 4.0.0.dev1

Thanks for reporting this. It's unfortunate it did not report more meaningful error message instead :-( Will try to address this soon.

Thanks for reporting. Just checked API, cute.crd2idx(layout, coord) should be cute.crd2idx(coord, layout).

We will improve the error report mechanism to provide better error message.
