            Bug ID: 98285
           Summary: xtensa doesn't use addx/subx instructions
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jcmvbkbc at gcc dot gnu.org
  Target Milestone: ---

Prior to version 6.1.0 gcc for xtensa used addx and subx instructions to
implement multiplication by small integer constants. After the commit
963ba1b26665 ("combine.c (make_compound_operation): Remove checks for
PLUS/MINUS rtx type.") it no longer does that.
