            Bug ID: 112919
           Summary: LoongArch: Alignments in tune parameters are not
                    precise and they regress performance
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xry111 at gcc dot gnu.org
  Target Milestone: ---

In r14-1839 we added -falign-function=3D32 -falign-label=3D16 for LA464.  B=
ut these
values is not precise now because in r14-4674 we removed
ASM_OUTPUT_ALIGN_WITH_NOP and altered the semantics of -falign-* switches. =
 And
we also have LA664 now which may benefit from a different value.=
