  32 /* Many parts of GCC use arrays that are indexed by machine mode and
  33    contain the insn codes for pattern in the MD file that perform a given
  34    operation on operands of that mode.
  35
  36    These patterns are present in the MD file with names that contain
  37    the mode(s) used and the name of the operation.  This program
  38    writes a function `init_all_optabs' that initializes the optabs with
  39    all the insn codes of the relevant patterns present in the MD file.
  40
  41    This array contains a list of optabs that need to be initialized.  Within
  42    each string, the name of the pattern to be matched against is delimited
  43    with $( and $).  In the string, $a and $b are used to match a short mode
  44    name (the part of the mode name not including `mode' and converted to
  45    lower-case).  When writing out the initializer, the entire string is
  46    used.  $A and $B are replaced with the full name of the mode; $a and $b
  47    are replaced with the short form of the name, as above.
  48
  49    If $N is present in the pattern, it means the two modes must be in
  50    the same mode class, and $b must be greater than $a (e.g, QImode
  51    and HImode).
  52
  53    $I means that only full integer modes should be considered for the
  54    next mode, and $F means that only float modes should be considered.
  55    $P means that both full and partial integer modes should be considered.
  56    $Q means that only fixed-point modes should be considered.
  57
  58    $V means to emit 'v' if the first mode is a MODE_FLOAT mode.
  59
  60    For some optabs, we store the operation by RTL codes.  These are only
  61    used for comparisons.  In that case, $c and $C are the lower-case and
  62    upper-case forms of the comparison, respectively.  */
