Re: md_atof is undocumented


Hi Harshad,

Oh alright.  I will check in the following patch to add the
documentation. :-)

+ @item md_atof (@var{type},@var{litP},@var{sizeP})
+ @cindex md_atof
+ This function is called to convert an ASCII string into a floating point value
+ in format used by the CPU.  It takes three arguments.  The first is @var{type}
+ which is a byte describing the type of floating point number to be created.
+ Possible values are @var{'f'} or @var{'s'} for single precision, @var{'d'} or
+ @var{'r'} for double precision and @var{'x'} or @var{'p'} for extended
+ precision.  Either lower or upper case versions of these letters can be used.
+ 
+ The second parameter is @var{litP} which is a pointer to a byte array where the
+ converted value should be stored.  The third argument is @var{sizeP}, which is
+ a pointer to a integer that should be filled in with the number of
+ @var{LITTLENUM}s emitted into the byte array.  (@var{LITTLENUM} is defined in
+ gas/bignum.h).  The function should return NULL upon success or an error string
+ upon failure.
