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 in the same mode class, and $b must be greater than $a (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. $Q means that only fixed-point 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. */ static const char * const optabs[] = { "set_convert_optab_handler (sext_optab, $B, $A,
