[Bug math/16348] New: x86 / x86_64 expl spurious underflows


https://sourceware.org/bugzilla/show_bug.cgi?id=16348

            Bug ID: 16348
           Summary: x86 / x86_64 expl spurious underflows
           Product: glibc
           Version: 2.19
            Status: NEW
          Severity: normal
          Priority: P2
         Component: math
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org

The x86 / x86_64 expl implementations produce spurious underflow exceptions for
arguments very close to 0 (in which case the result is very close to 1).  E.g.,
expl (0x1p-16384L) produces such exceptions for both x86_64 and x86.
