- // 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
- // defined in the AlphaUqToSfpOps enumeration
-
- alpha_dfptosq, // A generic function that converts double to a long.
- // How the conversion is performed is specified by the
- // second parameter, the possible values for which are
- // defined in the AlphaDfpToSqOps enumeration
-
- alpha_sfptosq, // A generic function that converts a float to a long.
- // How the conversion is performed is specified by the
- // second parameter, the possible values for which are
- // defined in the AlphaSfpToSq enumeration
