Yes fine.

Can you add this:

/* NOTE: cagney/2001-10-28: With the way things currently work, it isn't 
a good idea to leave the end bits undefined.  This is because GDB writes 
out the entire sizeof(<float>) bits of the floating point type even 
though the value might only be stored in, and the target processor may 
only refer to, the first N<LENGTH bits.  If the end of the buffer wasn't 
initialized, GDB would write undefined data to the target.  An errant 
program, refering to that undefined data, would would become 
non-deterministic.  */
