The problem here is that we have an indirect jump to a label.
JUMP_LABEL (insn) will be NULL but we will have a reg note REG_LABEL

Ahh, thanks for getting to the bottom of this one.  Is this bug on the
4.0 branch?


Yes this bug is on 4.0 branch too.  It has been a bug in GCC for a long
time too.  I don't understand how we nobody else noticed this bug
for a long time since:
2001-01-07  Alexandre Oliva  <aoliva@redhat.com>

Since this is a latent bug since then, it is a regression from 2.95.3.

Thanks,
Andrew Pinski
