// Instruction definitions
//===----------------------------------------------------------------------===//
// Each record of the class RVVBuiltin defines a collection of builtins (i.e.
// "def vadd : RVVBuiltin" will be used to define things like "vadd_vv_i32m1",
// "vadd_vv_i32m2", etc).
//
// The elements of this collection are defined by an instantiation process the
// range of which is specified by the cross product of the LMUL attribute and
// every element in the attribute TypeRange. By default builtins have LMUL = [1,
// 2, 4, 8, 1/2, 1/4, 1/8] so the process is repeated 7 times. In tablegen we
// use the Log2LMUL [0, 1, 2, 3, -1, -2, -3] to represent the LMUL.
//
// LMUL represents the fact that the types of values used by that builtin are
// values generated by instructions that are executed under that LMUL. However,
// this does not mean the builtin is necessarily lowered into an instruction
// that executes under the specified LMUL. An example where this happens are
// loads and stores of masks. A mask like `vbool8_t` can be generated, for
// instance, by comparing two `__rvv_int8m1_t` (this is LMUL=1) or comparing two
// `__rvv_int16m2_t` (this is LMUL=2). The actual load or store, however, will
// be performed under LMUL=1 because mask registers are not grouped.
//
// TypeRange is a non-empty sequence of basic types:
//
//   c: int8_t (i8)
//   s: int16_t (i16)
//   i: int32_t (i32)
//   l: int64_t (i64)
//   x: float16_t (half)
//   f: float32_t (float)
//   d: float64_t (double)
//
// This way, given an LMUL, a record with a TypeRange "sil" will cause the
// definition of 3 builtins. Each type "t" in the TypeRange (in this example
// they are int16_t, int32_t, int64_t) is used as a parameter that drives the
// definition of that particular builtin (for the given LMUL).
//
// During the instantiation, types can be transformed or modified using type
// transformers. Given a type "t" the following primitive type transformers can
// be applied to it to yield another type.
//
//   e: type of "t" as is (identity)
//   v: computes a vector type whose element type is "t" for the current LMUL
//   w: computes a vector type identical to what 'v' computes except for the
//      element type which is twice as wide as the element type of 'v'
//   q: computes a vector type identical to what 'v' computes except for the
//      element type which is four times as wide as the element type of 'v'
//   o: computes a vector type identical to what 'v' computes except for the
//      element type which is eight times as wide as the element type of 'v'
//   m: computes a vector type identical to what 'v' computes except for the
//      element type which is bool
//   0: void type, ignores "t"
//   z: size_t, ignores "t"
//   t: ptrdiff_t, ignores "t"
//   u: unsigned long, ignores "t"
//   l: long, ignores "t"
//
// So for instance if t is "i", i.e. int, then "e" will yield int again. "v"
// will yield an RVV vector type (assume LMUL=1), so __rvv_int32m1_t.
// Accordingly "w" would yield __rvv_int64m2_t.
//
// A type transformer can be prefixed by other non-primitive type transformers.
//
//   P: constructs a pointer to the current type
//   C: adds const to the type
//   K: requires the integer type to be a constant expression
//   U: given an integer type or vector type, computes its unsigned variant
//   I: given a vector type, compute the vector type with integer type
//      elements of the same width
//   F: given a vector type, compute the vector type with floating-point type
//      elements of the same width
//   S: given a vector type, computes its equivalent one for LMUL=1. This is a
//      no-op if the vector was already LMUL=1
//   (Log2EEW:Value): Log2EEW value could be 3/4/5/6 (8/16/32/64), given a
//      vector type (SEW and LMUL) and EEW (8/16/32/64), computes its
//      equivalent integer vector type with EEW and corresponding ELMUL (elmul =
//      (eew/sew) * lmul). For example, vector type is __rvv_float16m4
//      (SEW=16, LMUL=4) and Log2EEW is 3 (EEW=8), and then equivalent vector
//      type is __rvv_uint8m2_t (elmul=(8/16)*4 = 2). Ignore to define a new
//      builtins if its equivalent type has illegal lmul.
//   (FixedSEW:Value): Given a vector type (SEW and LMUL), and computes another
//      vector type which only changed SEW as given value. Ignore to define a new
//      builtin if its equivalent type has illegal lmul or the SEW does not changed.
//   (SFixedLog2LMUL:Value): Smaller Fixed Log2LMUL. Given a vector type (SEW
//      and LMUL), and computes another vector type which only changed LMUL as
//      given value. The new LMUL should be smaller than the old one. Ignore to
//      define a new builtin if its equivalent type has illegal lmul.
//   (LFixedLog2LMUL:Value): Larger Fixed Log2LMUL. Given a vector type (SEW
//      and LMUL), and computes another vector type which only changed LMUL as
//      given value. The new LMUL should be larger than the old one. Ignore to
//      define a new builtin if its equivalent type has illegal lmul.
//
// Following with the example above, if t is "i", then "Ue" will yield unsigned
// int and "Fv" will yield __rvv_float32m1_t (again assuming LMUL=1), Fw would
// yield __rvv_float64m2_t, etc.
//
// Each builtin is then defined by applying each type in TypeRange against the
// sequence of type transformers described in Suffix and Prototype.
//
// The name of the builtin is defined by the Name attribute (which defaults to
// the name of the class) appended (separated with an underscore) the Suffix
// attribute. For instance with Name="foo", Suffix = "v" and TypeRange = "il",
// the builtin generated will be __builtin_rvv_foo_i32m1 and
// __builtin_rvv_foo_i64m1 (under LMUL=1). If Suffix contains more than one
// type transformer (say "vv") each of the types is separated with an
// underscore as in "__builtin_rvv_foo_i32m1_i32m1".
//
// The C/C++ prototype of the builtin is defined by the Prototype attribute.
// Prototype is a non-empty sequence of type transformers, the first of which
// is the return type of the builtin and the rest are the parameters of the
// builtin, in order. For instance if Prototype is "wvv" and TypeRange is "si"
// a first builtin will have type
// __rvv_int32m2_t (__rvv_int16m1_t, __rvv_int16m1_t) and the second builtin
// will have type __rvv_int64m2_t (__rvv_int32m1_t, __rvv_int32m1_t) (again
// under LMUL=1).
