--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
The analysis sounds a bit confused. What is the transform that DOM cannot do
after the transform that FRE does? There's some older bug about out-of-SSA
coalescing issues with loops and liveness of induction variables but it's
not clear if this is related (the assembly doesn't show the loop exit block).
Can you name the loop in the source that is problematic?
See PR86270 and PR70359
