--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> ---
I don't care about the terminology.  We have 3 insns in play.  A, B and C.

We try to combine A -> B which succeeded before resulting in A, B' and C and
which in turn allowed a subsequent A -> C combination resulting in a final B',
C' sequence, eliminating A.  After the combiner patch in question no
combinations are done.

So, let's move past the argument on terminology and discuss the technical
issue.  This is something that worked in gcc-14 without the combiner patch. 
This is important for code generation.

How do you propose we address the regression?
