* ia64-tdep.c (ia64_gdbarch_init): Set up the gdbarch long double
        format to be the i387 extended float format which is used for
        long doubles stored in memory.

80 bits. An OS may choose to use this format (e.g. Linux) or choose to use
a different format for storing long doubles (e.g. HPUX). In the latter case,
the setting of the format may be moved/overridden in an OS-specific tdep file. */
