;; SSE logical operations.
+;; SSE defines logical operations on floating point values. This brings
+;; interesting challenge to RTL representation where logicals are only valid
+;; on integral types. We deal with this by representing the floating point
+;; logical as logical on arguments casted to TImode as this is what hardware
+;; really does. Unfortunately hardware requires the type information to be
+;; present and thus we must avoid subregs from being simplified and elliminated
+;; in later compilation phases.
+;;
+;; We have following variants from each instruction:
+;; sse_andsf3 - the operation taking V4SF vector operands
+;; and doing TImode cast on them
+;; *sse_andsf3_memory - the operation taking one memory operand casted to
+;; TImode, since backend insist on elliminating casts
+;; on memory operands
+;; sse_andti3_sf_1 - the operation taking SF scalar operands.
+;; We can not accept memory operand here as instruction reads
+;; whole scalar. This is generated only post reload by GCC
+;; scalar float operations that expands to logicals (fabs)
+;; sse_andti3_sf_2 - the operation taking SF scalar input and TImode
+;; memory operand. Eventually combine can be able
+;; to synthetize these using splitter.
+;; sse2_anddf3, *sse2_anddf3_memory
+;;
+;;
;; These are not called andti3 etc. because we really really don't want
;; the compiler to widen DImode ands to TImode ands and then try to move
;; into DImode subregs of SSE registers, and them together, and move out
;; of DImode subregs again!
