Subject: [Bug tree-optimization/108705] [13 Regression] Unexpected CPU time usage with LTO in ranger propagation
Date: Wed, 08 Feb 2023 04:39:55 +0000	[thread overview]
Message-ID: <bug-108705-4-CCKF5RqZUb@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #1 from Rimvydas (RJ) <rimvydas.jas at gmail dot com> ---
Using assumed shape arrays "p(:),s(:)" in bar() requires longer chain of calls
to foo() and all time spent moves to "tree VRP", but produced assembly is more
cluttered than with assumed size array declarations.  Original code trips on
both variants in different ltrans partitions during LTO link.
