-// Each intrinsic is a subclass of the Inst class. An intrinsic can either
-// generate a __builtin_* call or it can expand to a set of generic operations.
-//
-// The operations are subclasses of Operation providing a list of DAGs, the
-// last of which is the return value. The available DAG nodes are documented
-// below.
-//
-//===----------------------------------------------------------------------===//
-
-// The base Operation class. All operations must subclass this.
-class Operation<list<dag> ops=[]> {
- list<dag> Ops = ops;
- bit Unavailable = 0;
-}
-// An operation that only contains a single DAG.
-class Op<dag op> : Operation<[op]>;
-// A shorter version of Operation - takes a list of DAGs. The last of these will
-// be the return value.
-class LOp<list<dag> ops> : Operation<ops>;
-
-// These defs and classes are used internally to implement the SetTheory
-// expansion and should be ignored.

-//===----------------------------------------------------------------------===//
-// Available operations
-//===----------------------------------------------------------------------===//
-
-// DAG arguments can either be operations (documented below) or variables.
-// Variables are prefixed with '$'. There are variables for each input argument,
-// with the name $pN, where N starts at zero. So the zero'th argument will be
-// $p0, the first $p1 etc.
-
-// op - Binary or unary operator, depending on the number of arguments. The
-// operator itself is just treated as a raw string and is not checked.
-// example: (op "+", $p0, $p1) -> "__p0 + __p1".
-// (op "-", $p0) -> "-__p0"
-def op;
-// call - Invoke another intrinsic. The input types are type checked and
-// disambiguated. If there is no intrinsic defined that takes
-// the given types (or if there is a type ambiguity) an error is
-// generated at tblgen time. The name of the intrinsic is the raw
-// name as given to the Inst class (not mangled).
-// example: (call "vget_high", $p0) -> "vgetq_high_s16(__p0)"
-// (assuming $p0 has type int16x8_t).
-def call;
-// cast - Perform a cast to a different type. This gets emitted as a static
-// C-style cast. For a pure reinterpret cast (T x = *(T*)&y), use
-// "bitcast".
-//
-// The syntax is (cast MOD* VAL). The last argument is the value to
-// cast, preceded by a sequence of type modifiers. The target type
-// starts off as the type of VAL, and is modified by MOD in sequence.
-// The available modifiers are:
-// - $X - Take the type of parameter/variable X. For example:
-// (cast $p0, $p1) would cast $p1 to the type of $p0.
-// - "R" - The type of the return type.
-// - A typedef string - A NEON or stdint.h type that is then parsed.
-// for example: (cast "uint32x4_t", $p0).
-// - "U" - Make the type unsigned.
-// - "S" - Make the type signed.
-// - "H" - Halve the number of lanes in the type.
-// - "D" - Double the number of lanes in the type.
-// - "8" - Convert type to an equivalent vector of 8-bit signed
-// integers.
-// example: (cast "R", "U", $p0) -> "(uint32x4_t)__p0" (assuming the return
-// value is of type "int32x4_t".
-// (cast $p0, "D", "8", $p1) -> "(int8x16_t)__p1" (assuming __p0
-// has type float64x1_t or any other vector type of 64 bits).
-// (cast "int32_t", $p2) -> "(int32_t)__p2"
-def cast;
-// bitcast - Same as "cast", except a reinterpret-cast is produced:
-// (bitcast "T", $p0) -> "*(T*)&__p0".
-// The VAL argument is saved to a temporary so it can be used
-// as an l-value.
-def bitcast;
-// dup - Take a scalar argument and create a vector by duplicating it into
-// all lanes. The type of the vector is the base type of the intrinsic.
-// example: (dup $p1) -> "(uint32x2_t) {__p1, __p1}" (assuming the base type
-// is uint32x2_t).
-def dup;
-// splat - Take a vector and a lane index, and return a vector of the same type
-// containing repeated instances of the source vector at the lane index.
-// example: (splat $p0, $p1) ->
-// "__builtin_shufflevector(__p0, __p0, __p1, __p1, __p1, __p1)"
-// (assuming __p0 has four elements).
-def splat;
-// save_temp - Create a temporary (local) variable. The variable takes a name
-// based on the zero'th parameter and can be referenced using
-// using that name in subsequent DAGs in the same
-// operation. The scope of a temp is the operation. If a variable
-// with the given name already exists, an error will be given at
-// tblgen time.
-// example: [(save_temp $var, (call "foo", $p0)),
-// (op "+", $var, $p1)] ->
-// "int32x2_t __var = foo(__p0); return __var + __p1;"
-def save_temp;
-// name_replace - Return the name of the current intrinsic with the first
-// argument replaced by the second argument. Raises an error if
-// the first argument does not exist in the intrinsic name.
-// example: (call (name_replace "_high_", "_"), $p0) (to call the non-high
-// version of this intrinsic).
-def name_replace;
-// literal - Create a literal piece of code. The code is treated as a raw
-// string, and must be given a type. The type is a stdint.h or
-// NEON intrinsic type as given to (cast).
-// example: (literal "int32_t", "0")
-def literal;
-// shuffle - Create a vector shuffle. The syntax is (shuffle ARG0, ARG1, MASK).
-// The MASK argument is a set of elements. The elements are generated
-// from the two special defs "mask0" and "mask1". "mask0" expands to
-// the lane indices in sequence for ARG0, and "mask1" expands to
-// the lane indices in sequence for ARG1. They can be used as-is, e.g.
-//
-// (shuffle $p0, $p1, mask0) -> $p0
-// (shuffle $p0, $p1, mask1) -> $p1
-//
-// or, more usefully, they can be manipulated using the SetTheory
-// operators plus some extra operators defined in the NEON emitter.
-// The operators are described below.
-// example: (shuffle $p0, $p1, (add (highhalf mask0), (highhalf mask1))) ->
-// A concatenation of the high halves of the input vectors.
-def shuffle;
-
-// add, interleave, decimate: These set operators are vanilla SetTheory
-// operators and take their normal definition.
-def add;
-def interleave;
-def decimate;
-// rotl - Rotate set left by a number of elements.
-// example: (rotl mask0, 3) -> [3, 4, 5, 6, 0, 1, 2]
-def rotl;
-// rotl - Rotate set right by a number of elements.
-// example: (rotr mask0, 3) -> [4, 5, 6, 0, 1, 2, 3]
-def rotr;
-// highhalf - Take only the high half of the input.
-// example: (highhalf mask0) -> [4, 5, 6, 7] (assuming mask0 had 8 elements)
-def highhalf;
-// highhalf - Take only the low half of the input.
-// example: (lowhalf mask0) -> [0, 1, 2, 3] (assuming mask0 had 8 elements)
-def lowhalf;
-// rev - Perform a variable-width reversal of the elements. The zero'th argument
-// is a width in bits to reverse. The lanes this maps to is determined
-// based on the element width of the underlying type.
-// example: (rev 32, mask0) -> [3, 2, 1, 0, 7, 6, 5, 4] (if 8-bit elements)
-// example: (rev 32, mask0) -> [1, 0, 3, 2] (if 16-bit elements)

-// Every intrinsic subclasses "Inst". An intrinsic has a name, a prototype and
-// a sequence of typespecs.
-//
-// The name is the base name of the intrinsic, for example "vget_lane". This is
-// then mangled by the tblgen backend to add type information ("vget_lane_s16").
-//
-// A typespec is a sequence of uppercase characters (modifiers) followed by one
-// lowercase character. A typespec encodes a particular "base type" of the
-// intrinsic.
-//
-// An example typespec is "Qs" - quad-size short - uint16x8_t. The available
-// typespec codes are given below.
-//
-// The string given to an Inst class is a sequence of typespecs. The intrinsic
-// is instantiated for every typespec in the sequence. For example "sdQsQd".
-//
-// The prototype is a string that defines the return type of the intrinsic
-// and the type of each argument. The return type and every argument gets a
-// "modifier" that can change in some way the "base type" of the intrinsic.
-//
-// The modifier 'd' means "default" and does not modify the base type in any
-// way. The available modifiers are given below.

+// Each intrinsic is a subclass of the Inst class. An intrinsic can either

+//
+// The operations are subclasses of Operation providing a list of DAGs, the
+// last of which is the return value. The available DAG nodes are documented

+//
+//===----------------------------------------------------------------------===//
+
+// The base Operation class. All operations must subclass this.
+class Operation<list<dag> ops=[]> {

+// An operation that only contains a single DAG.

+//===----------------------------------------------------------------------===//
+// Available operations
+//===----------------------------------------------------------------------===//
+
+// DAG arguments can either be operations (documented below) or variables.
+// Variables are prefixed with '$'. There are variables for each input argument,
+// with the name $pN, where N starts at zero. So the zero'th argument will be
+// $p0, the first $p1 etc.
+
+// op - Binary or unary operator, depending on the number of arguments. The
+// operator itself is just treated as a raw string and is not checked.
+// example: (op "+", $p0, $p1) -> "__p0 + __p1".
+// (op "-", $p0) -> "-__p0"
+def op;
+// call - Invoke another intrinsic. The input types are type checked and
+// disambiguated. If there is no intrinsic defined that takes
+// the given types (or if there is a type ambiguity) an error is
+// generated at tblgen time. The name of the intrinsic is the raw
+// name as given to the Inst class (not mangled).
+// example: (call "vget_high", $p0) -> "vgetq_high_s16(__p0)"
+// (assuming $p0 has type int16x8_t).
+def call;
+// cast - Perform a cast to a different type. This gets emitted as a static
+// C-style cast. For a pure reinterpret cast (T x = *(T*)&y), use
+// "bitcast".
+//
+// The syntax is (cast MOD* VAL). The last argument is the value to
+// cast, preceded by a sequence of type modifiers. The target type
+// starts off as the type of VAL, and is modified by MOD in sequence.
+// The available modifiers are:
+// - $X - Take the type of parameter/variable X. For example:
+// (cast $p0, $p1) would cast $p1 to the type of $p0.
+// - "R" - The type of the return type.
+// - A typedef string - A NEON or stdint.h type that is then parsed.
+// for example: (cast "uint32x4_t", $p0).
+// - "U" - Make the type unsigned.
+// - "S" - Make the type signed.
+// - "H" - Halve the number of lanes in the type.
+// - "D" - Double the number of lanes in the type.
+// - "8" - Convert type to an equivalent vector of 8-bit signed
+// integers.
+// example: (cast "R", "U", $p0) -> "(uint32x4_t)__p0" (assuming the return
+// value is of type "int32x4_t".
+// (cast $p0, "D", "8", $p1) -> "(int8x16_t)__p1" (assuming __p0
+// has type float64x1_t or any other vector type of 64 bits).
+// (cast "int32_t", $p2) -> "(int32_t)__p2"
+def cast;
+// bitcast - Same as "cast", except a reinterpret-cast is produced:
+// (bitcast "T", $p0) -> "*(T*)&__p0".
+// The VAL argument is saved to a temporary so it can be used
+// as an l-value.
+def bitcast;
+// dup - Take a scalar argument and create a vector by duplicating it into
+// all lanes. The type of the vector is the base type of the intrinsic.
+// example: (dup $p1) -> "(uint32x2_t) {__p1, __p1}" (assuming the base type
+// is uint32x2_t).
+def dup;
+// splat - Take a vector and a lane index, and return a vector of the same type
+// containing repeated instances of the source vector at the lane index.
+// example: (splat $p0, $p1) ->
+// "__builtin_shufflevector(__p0, __p0, __p1, __p1, __p1, __p1)"
+// (assuming __p0 has four elements).
+def splat;
+// save_temp - Create a temporary (local) variable. The variable takes a name
+// based on the zero'th parameter and can be referenced using
+// using that name in subsequent DAGs in the same
+// operation. The scope of a temp is the operation. If a variable
+// with the given name already exists, an error will be given at
+// tblgen time.
+// example: [(save_temp $var, (call "foo", $p0)),
+// (op "+", $var, $p1)] ->
+// "int32x2_t __var = foo(__p0); return __var + __p1;"
+def save_temp;
+// name_replace - Return the name of the current intrinsic with the first
+// argument replaced by the second argument. Raises an error if
+// the first argument does not exist in the intrinsic name.
+// example: (call (name_replace "_high_", "_"), $p0) (to call the non-high
+// version of this intrinsic).
+def name_replace;
+// literal - Create a literal piece of code. The code is treated as a raw
+// string, and must be given a type. The type is a stdint.h or
+// NEON intrinsic type as given to (cast).
+// example: (literal "int32_t", "0")
+def literal;
+// shuffle - Create a vector shuffle. The syntax is (shuffle ARG0, ARG1, MASK).
+// The MASK argument is a set of elements. The elements are generated
+// from the two special defs "mask0" and "mask1". "mask0" expands to
+// the lane indices in sequence for ARG0, and "mask1" expands to
+// the lane indices in sequence for ARG1. They can be used as-is, e.g.
+//
+// (shuffle $p0, $p1, mask0) -> $p0
+// (shuffle $p0, $p1, mask1) -> $p1
+//
+// or, more usefully, they can be manipulated using the SetTheory
+// operators plus some extra operators defined in the NEON emitter.
+// The operators are described below.
+// example: (shuffle $p0, $p1, (add (highhalf mask0), (highhalf mask1))) ->
+// A concatenation of the high halves of the input vectors.
+def shuffle;
+
+// add, interleave, decimate: These set operators are vanilla SetTheory
+// operators and take their normal definition.
+def add;
+def interleave;
+def decimate;
+// rotl - Rotate set left by a number of elements.
+// example: (rotl mask0, 3) -> [3, 4, 5, 6, 0, 1, 2]
+def rotl;
+// rotl - Rotate set right by a number of elements.
+// example: (rotr mask0, 3) -> [4, 5, 6, 0, 1, 2, 3]
+def rotr;
+// highhalf - Take only the high half of the input.
+// example: (highhalf mask0) -> [4, 5, 6, 7] (assuming mask0 had 8 elements)
+def highhalf;
+// highhalf - Take only the low half of the input.
+// example: (lowhalf mask0) -> [0, 1, 2, 3] (assuming mask0 had 8 elements)
+def lowhalf;
+// rev - Perform a variable-width reversal of the elements. The zero'th argument
+// is a width in bits to reverse. The lanes this maps to is determined
+// based on the element width of the underlying type.
+// example: (rev 32, mask0) -> [3, 2, 1, 0, 7, 6, 5, 4] (if 8-bit elements)
+// example: (rev 32, mask0) -> [1, 0, 3, 2] (if 16-bit elements)

+// Every intrinsic subclasses "Inst". An intrinsic has a name, a prototype and
+// a sequence of typespecs.
+//
+// The name is the base name of the intrinsic, for example "vget_lane". This is
+// then mangled by the tblgen backend to add type information ("vget_lane_s16").
+//
+// A typespec is a sequence of uppercase characters (modifiers) followed by one
+// lowercase character. A typespec encodes a particular "base type" of the
+// intrinsic.
+//
+// An example typespec is "Qs" - quad-size short - uint16x8_t. The available
+// typespec codes are given below.
+//
+// The string given to an Inst class is a sequence of typespecs. The intrinsic
+// is instantiated for every typespec in the sequence. For example "sdQsQd".
+//
+// The prototype is a string that defines the return type of the intrinsic
+// and the type of each argument. The return type and every argument gets a
+// "modifier" that can change in some way the "base type" of the intrinsic.
+//
+// The modifier 'd' means "default" and does not modify the base type in any
+// way. The available modifiers are given below.
