// This section defines intrinsic functions used to represent Alpha
|
|
||||||
// instructions.
|
|
||||||
//
|
|
||||||
alpha_ctlz, // CTLZ (count leading zero): counts the number of leading
|
|
||||||
// zeros in the given ulong value
|
|
||||||
|
|
||||||
alpha_cttz, // CTTZ (count trailing zero): counts the number of trailing
|
|
||||||
// zeros in the given ulong value
|
|
||||||
|
|
||||||
alpha_ctpop, // CTPOP (count population): counts the number of ones in
|
|
||||||
// the given ulong value
|
|
||||||
|
|
||||||
alpha_umulh, // UMULH (unsigned multiply quadword high): Takes two 64-bit
|
|
||||||
// (ulong) values, and returns the upper 64 bits of their
|
|
||||||
// 128 bit product as a ulong
|
|
||||||
|
|
||||||
alpha_vecop, // A generic vector operation. This function is used to
|
|
||||||
// represent various Alpha vector/multimedia instructions.
|
|
||||||
// It takes 4 parameters:
|
|
||||||
// - the first two are 2 ulong vectors
|
|
||||||
// - the third (uint) is the size (in bytes) of each
|
|
||||||
// vector element. Thus a value of 1 means that the two
|
|
||||||
// input vectors consist of 8 bytes
|
|
||||||
// - the fourth (uint) is the operation to be performed on
|
|
||||||
// the vectors. Its possible values are defined in the
|
|
||||||
// enumeration AlphaVecOps.
|
|
||||||
|
|
||||||
alpha_pup, // A pack/unpack operation. This function is used to
|
|
||||||
// represent Alpha pack/unpack operations.
|
|
||||||
// It takes 3 parameters:
|
|
||||||
// - the first is an ulong to pack/unpack
|
|
||||||
// - the second (uint) is the size of each component
|
|
||||||
// Valid values are 2 (word) or 4 (longword)
|
|
||||||
// - the third (uint) is the operation to be performed.
|
|
||||||
// Possible values defined in the enumeration
|
|
||||||
// AlphaPupOps
|
|
||||||
|
|
||||||
alpha_bytezap, // This intrinsic function takes two parameters: a ulong
|
|
||||||
// (64-bit) value and a ubyte value, and returns a ulong.
|
|
||||||
// Each bit in the ubyte corresponds to a byte in the
|
|
||||||
// ulong. If the bit is 0, the byte in the output equals
|
|
||||||
// the corresponding byte in the input, else the byte in
|
|
||||||
// the output is zero.
|
|
||||||
|
|
||||||
alpha_bytemanip,// This intrinsic function represents all Alpha byte
|
|
||||||
// manipulation instructions. It takes 3 parameters:
|
|
||||||
// - The first two are ulong inputs to operate on
|
|
||||||
// - The third (uint) is the operation to perform.
|
|
||||||
// Possible values defined in the enumeration
|
|
||||||
// AlphaByteManipOps
|
|
||||||
|
|
||||||
alpha_dfpbop, // This intrinsic function represents Alpha instructions
|
|
||||||
// that operate on two doubles and return a double. The
|
|
||||||
// first two parameters are the two double values to
|
|
||||||
// operate on, and the third is a uint that specifies the
|
|
||||||
// operation to perform. Its possible values are defined in
|
|
||||||
// the enumeration AlphaFloatingBinaryOps
|
|
||||||
|
|
||||||
alpha_dfpuop, // This intrinsic function represents operation on a single
|
|
||||||
// double precision floating point value. The first
|
|
||||||
// paramters is the value and the second is the operation.
|
|
||||||
// The possible values for the operations are defined in the
|
|
||||||
// enumeration AlphaFloatingUnaryOps
|
|
||||||
|
|
||||||
alpha_unordered,// This intrinsic function tests if two double precision
|
|
||||||
// floating point values are unordered. It has two
|
|
||||||
// parameters: the two values to be tested. It return a
|
|
||||||
// boolean true if the two are unordered, else false.
|
|
||||||
|
|
||||||
alpha_uqtodfp, // A generic function that converts a ulong to a double.
|
|
||||||
// How the conversion is performed is specified by the
|
|
||||||
// second parameter, the possible values for which are
|
|
||||||
// defined in the AlphaUqToDfpOps enumeration
|
|
||||||
|
|
||||||
alpha_uqtosfp, // A generic function that converts a ulong to a float.
|
|
||||||
// How the conversion is performed is specified by the
|

||||||
// second parameter, the possible values for which are
|
|
||||||

// second parameter, the possible values for which are
|
|
||||||
// defined in the AlphaDfpToSqOps enumeration
