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.
|
|
|
35
|
|
|
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.
|
|
|
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 $Q means that only fixed-point modes should be considered.
|
|
|
55
|
|
|
56 $V means to emit 'v' if the first mode is a MODE_FLOAT mode.
|
|
|
57
|
|
|
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. */
