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 consecutive 50 widths in the same mode class (e.g, QImode and HImode). $I means that 51 only full integer modes should be considered for the next mode, and $F 52 means that only float modes should be considered. 53 $P means that both full and partial integer modes should be considered. 54 55 $V means to emit 'v' if the first mode is a MODE_FLOAT mode. 56 57 For some optabs, we store the operation by RTL codes. These are only 58 used for comparisons. In that case, $c and $C are the lower-case and 59 upper-case forms of the comparison, respectively. */ 60 61static const char * const optabs[] = 62{ "sext_optab->handlers[$B][$A].insn_code =
