template Vector(T)
Create a vector type.

Parameters:
T = one of double[2], float[4], void[16], byte[16], ubyte[16], short[8], ushort[8], int[4], uint[4], long[2], ulong[2]. For 256 bit vectors, one of double[4], float[8], void[32], byte[32], ubyte[32], short[16], ushort[16], int[8], uint[8], long[4], ulong[4]

alias void16 = __vector(void[16]);

alias double2 = __vector(double[2]);

alias float4 = __vector(float[4]);

alias byte16 = __vector(byte[16]);

alias ubyte16 = __vector(ubyte[16]);

alias short8 = __vector(short[8]);

alias ushort8 = __vector(ushort[8]);

alias int4 = __vector(int[4]);

alias uint4 = __vector(uint[4]);

alias long2 = __vector(long[2]);

alias ulong2 = __vector(ulong[2]);

alias void32 = __vector(void[32]);

alias double4 = __vector(double[4]);

alias float8 = __vector(float[8]);

alias byte32 = __vector(byte[32]);

alias ubyte32 = __vector(ubyte[32]);

alias short16 = __vector(short[16]);

alias ushort16 = __vector(ushort[16]);

alias int8 = __vector(int[8]);

alias uint8 = __vector(uint[8]);

alias long4 = __vector(long[4]);

alias ulong4 = __vector(ulong[4]);

enum XMM: int;
XMM opcodes that conform to the following:

opcode xmm1,xmm2/mem

and do not have side effects (i.e. do not write to memory).

pure nothrow @safe void16 __simd(XMM opcode, void16 op1, void16 op2);
Generate two operand instruction with XMM 128 bit operands.

This is a compiler magic function - it doesn't behave like regular D functions.

Parameters:
opcode any of the XMM opcodes; it must be a compile time constant op1 first operand op2 second operand

Returns:
result of opcode

pure nothrow @safe void16 __simd(XMM opcode, void16 op1);
Unary SIMD instructions.

pure nothrow @safe void16 __simd(XMM opcode, double d);

pure nothrow @safe void16 __simd(XMM opcode, float f);

pure nothrow @safe void16 __simd(XMM opcode, void16 op1, void16 op2, ubyte imm8);
For instructions: CMPPD, CMPSS, CMPSD, CMPPS, PSHUFD, PSHUFHW, PSHUFLW, BLENDPD, BLENDPS, DPPD, DPPS, MPSADBW, PBLENDW, ROUNDPD, ROUNDPS, ROUNDSD, ROUNDSS

Parameters:
opcode any of the above XMM opcodes; it must be a compile time constant op1 first operand op2 second operand imm8 third operand; must be a compile time constant

Returns:
result of opcode

pure nothrow @safe void16 __simd_ib(XMM opcode, void16 op1, ubyte imm8);
For instructions with the imm8 version: PSLLD, PSLLQ, PSLLW, PSRAD, PSRAW, PSRLD, PSRLQ, PSRLW, PSRLDQ, PSLLDQ

Parameters:
opcode any of the XMM opcodes; it must be a compile time constant op1 first operand imm8 second operand; must be a compile time constant

Returns:
result of opcode

pure nothrow @safe void16 __simd_sto(XMM opcode, void16 op1, void16 op2);
For "store" operations of the form: op1 op= op2

Returns:
op2 These cannot be marked as pure, as semantic() doesn't check them.

pure nothrow @safe void16 __simd_sto(XMM opcode, double op1, void16 op2);

pure nothrow @safe void16 __simd_sto(XMM opcode, float op1, void16 op2);
