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.
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.
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.
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 $Q means that only fixed-point modes should be considered.
56 $V means to emit 'v' if the first mode is a MODE_FLOAT mode.
58 For some optabs, we store the operation by RTL codes. These are only
59 used for comparisons. In that case, $c and $C are the lower-case and
60 upper-case forms of the comparison, respectively. */
