failed to legalize operation 'arith.sitofp'

[jinchen62]

What happened?

Following up issue of llvm/torch-mlir#3903.
Error log: https://gist.github.com/jinchen62/8059b38cc52770464b848da380815f2b

Compilation failed in iree-vm-conversion pass. The arith.sitofp comes from converting a dynamic input shape to float for calculating the resized shape by multiplying scales. Static shape would pass compilation, so I wonder if something in frontend should be changed or we could support it in iree compilation.

Steps to reproduce your issue

iree-compile --iree-hal-target-backends=llvm-cpu --iree-llvmcpu-target-cpu=host repro_linalg.mlir -o test.vmfb
