            Bug ID: 96044
           Summary: GCC hangs in tight loop resolving __builtin_jn using
                    MPFR
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: acoplan at gcc dot gnu.org
  Target Milestone: ---

On the following code:

void f(void)
{
  __builtin_jn(73333,73333);
}

GCC since 4.3 hangs in a tight loop inside MPFR code trying to constant fold
the call away.
