            Bug ID: 93390
           Summary: AARCH64: FP move costs needs improvements for
                    ThunderX2
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dpochepk at gmail dot com
  Target Milestone: ---
            Target: aarch64-thunderx2t99

Current cpu_regmove_cost for thunderx2t99 seems to be not optimal. Preliminary
experiments and benchmarks (SPEC) shows that a little bit lower values for
FP-related entries get better results. I'd like to proceed on this one.
