            Bug ID: 61979
           Summary: Why float variable loading twice into the FTU Stack
                    during condition checking ?
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org

Actually its not a bug. But i identified that float variables are loading twice
into the FTU STACK during the condition checking ,that's actually my doubt and
i check without loading it again i remove repeated code and getting the same
output . But why gcc complier loads the float variable again into the FTU Stack
? For checking the condition it first  checks the parity flags(whether NAN ,INF
)then it again loads the float variable into FTU stack and check for the zero
flag( whether non zero) set or not. But  we can directly check the zero flag
after checking parity flag  with out loading the variable into the FTU stack.
