-/* 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 integer modes should be considered for the next mode, and %F means
-   that only float modes should be considered.
-
-   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.  */
-
-/* The reason we use \% is to avoid sequences of the form %-capletter-%
-   which SCCS treats as magic.  This gets warnings which you should ignore.  */
