Subject: [Bug rtl-optimization/101523] Huge number of combine attempts
Date: Wed, 06 Mar 2024 22:53:07 +0000	[thread overview]
Message-ID: <bug-101523-4-vhdwxvEsWd@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #17 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Why does this happen so extremely often for s390x customers?  It should from
first principles happen way more often for e.g. powerpc, but we never see such
big problems, let alone "all of the time"!

So what is really happening?  And, when did this start, anyway, because
apparently
at some point in time all was fine?
