            Bug ID: 117973
           Summary: [15 Regression] Dead Code Elimination Regression since
                    r15-5646-gd1cf0d7a0f27fd for
                    non-LOGICAL_OP_NON_SHORT_CIRCUIT targets
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: missed-optimization, patch
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hp at gcc dot gnu.org
        Depends on: 111456
  Target Milestone: ---

+++ This bug was initially created as a clone of Bug #111456 +++
The test-case gcc.dg/tree-ssa/pr111456-1.c started to fail for
non-LOGICAL_OP_NON_SHORT_CIRCUIT targets with commit r15-5646-gd1cf0d7a0f27fd,
as described in PR117954.  Before that commit, there was no difference
regarding between LOGICAL_OP_NON_SHORT_CIRCUITness.  On request by the author
of that patch, this PR tracks fallout for non-LOGICAL_OP_NON_SHORT_CIRCUIT
targets, while the test-case gcc.dg/tree-ssa/pr111456-1.c is adjusted to cover
only LOGICAL_OP_NON_SHORT_CIRCUIT targets, discriminating by use of
--param=logical-op-non-short-circuit.
