Hi, Robin. Would you mind give me preprocessed file to reproduce the issue ?
I suspect it triggers latent bug in VSETVL PASS.
So it looks like vsetvl has made a transformation that makes DCE go into
a loop. At least that's my first impression after attaching to a hung
build. The good news is I was able to trigger it without LTO. I'll
send the relevant info separately so as not to spam everyone with the
testcase :-)
