           Summary: tanf spurious underflows
           Product: glibc
           Version: 2.21
            Status: NEW
          Severity: normal

         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

The flt-32 implementation of tanf produces spurious underflow exceptions.  For
example, on x86_64, tanf (0x1p-27f) produces such an exception.
