/* Many parts of GCC use arrays that are indexed by machine mode and
   contain the insn codes for pattern in the MD file that perform a given
   operation on operands of that mode.

   These patterns are present in the MD file with names that contain
   the mode(s) used and the name of the operation.  This program
   writes a function `init_all_optabs' that initializes the optabs with
   all the insn codes of the relevant patterns present in the MD file.

   This array contains a list of optabs that need to be initialized.  Within
   each string, the name of the pattern to be matched against is delimited
   with $( and $).  In the string, $a and $b are used to match a short mode
   name (the part of the mode name not including `mode' and converted to
   lower-case).  When writing out the initializer, the entire string is
   used.  $A and $B are replaced with the full name of the mode; $a and $b
   are replaced with the short form of the name, as above.

   If $N is present in the pattern, it means the two modes must be consecutive
   widths in the same mode class (e.g, QImode and HImode).  $I means that
   only full integer modes should be considered for the next mode, and $F
   means that only float modes should be considered.
   $P means that both full and partial integer modes should be considered.

   $V means to emit 'v' if the first mode is a MODE_FLOAT mode.

   For some optabs, we store the operation by RTL codes.  These are only
   used for comparisons.  In that case, $c and $C are the lower-case and
   upper-case forms of the comparison, respectively.  */
