/* 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
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
+ 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
+ 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.
+ 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 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.
+
+ $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
+ 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-%
