            Bug ID: 97083
           Summary: __builtin_lround and _builtin_llround not replaced
                    with fcvtas on aarch64
           Product: gcc
           Version: 10.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: linux at carewolf dot com
  Target Milestone: ---

On aarch64 calling __builtin_round and casting the result to int or long long
uses a single fcvtas instruction, but using __builtin_lround or
__builtin_llround instead will do function call.

Seems like they are missing the same optimization.
