/* 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
   operation on operands of that mode.

   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 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
   upper-case forms of the comparison, respectively.  */

af9e4a0c RK	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
1b3459d2	43	with $( and $). In the string, $a and $b are used to match a short mode
af9e4a0c RK	44	name (the part of the mode name not including `mode' and converted to
af9e4a0c RK	45	lower-case). When writing out the initializer, the entire string is
1b3459d2	46	used. $A and $B are replaced with the full name of the mode; $a and $b
af9e4a0c RK	47	are replaced with the short form of the name, as above.
af9e4a0c RK	48
1b3459d2 ZW	49	If $N is present in the pattern, it means the two modes must be consecutive
1b3459d2 ZW	50	widths in the same mode class (e.g, QImode and HImode). $I means that
91ce572a CC	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.
af9e4a0c RK	56
af9e4a0c RK	57	For some optabs, we store the operation by RTL codes. These are only
1b3459d2	58	used for comparisons. In that case, $c and $C are the lower-case and
af9e4a0c RK	59	upper-case forms of the comparison, respectively. */
