Confirm this is the latent bug in VSETVL PASS which is already existed for a

Hi,
I believe the issue is that you're using rv64gc, not rv64gcv.
I haven't tried building with multilib, so my commands are:

Trunk optimized stuff return 0, but fails to optimize out functions which
becomes unused after indirect inlining.
With -fno-early-inlining we end up with:
