[FLANG] fails to trigger LoopInterchange pass

[buggfg]

I pulled the LLVM main branch today and found that explicitly enabling LoopInterchangePass does not trigger the pass:

flang-new -S -o xxx.ll -O3 -flto -march=rocketlake -mllvm -enable-loopinterchange=true xxx.f

And On 2023-08-25 flang-new successfully invoked LoopInterchangePass.

Am I missing something?

Have you tried -floop-interchange instead? This option was introduced in #140182.

Thanks! This option works.
