## Semantics




      A direct method for generating a GEN native split send message

## Description



    A raw message send that will be translated into a GEN split send instruction

- **Modifiers(ub):** 
 
  - Bit[0]: Determines whether sends or sendsc should be used
 
    - 0b0:  raw_sends 
    - 0b1:  raw_sendsc 
  - Bit[1]: Determines whether EOT is set or not

- **Exec_size(ub):** Execution size
 
  - Bit[2..0]: size of the region for source and destination operands
 
    - 0b000:  1 element (scalar) 
    - 0b001:  2 elements 
    - 0b010:  4 elements 
    - 0b011:  8 elements 
    - 0b100:  16 elements 
    - 0b101:  32 elements 
  - Bit[7..4]: execution mask (explicit control over the enabled channels)
 
    - 0b0000:  M1 
    - 0b0001:  M2 
    - 0b0010:  M3 
    - 0b0011:  M4 
    - 0b0100:  M5 
    - 0b0101:  M6 
    - 0b0110:  M7 
    - 0b0111:  M8 
    - 0b1000:  M1_NM 
    - 0b1001:  M2_NM 
    - 0b1010:  M3_NM 
    - 0b1011:  M4_NM 
    - 0b1100:  M5_NM 
    - 0b1101:  M6_NM 
    - 0b1110:  M7_NM 
    - 0b1111:  M8_NM
- **Pred(uw):** Predication control

- **SFID(ub):** Shared function Id targeted by this send message. Valid values are  [0-15]

- **NumSrc0(ub):** Number of GRF registers for the send message payload 0

- **NumSrc1(ub):** Number of GRF registers for the send message payload 1

- **NumDst(ub):** Number of GRF registers for the send message response

- **ExMsgDesc(scalar):** Extended message descriptor for the send. Must have type UD

- **Desc(scalar):** Message descriptor for the send. Must have type UD

- **Src0(raw_operand):** The general variable storing the send  message payload 0

- **Src1(raw_operand):** The general variable storing the send message payload 1

- **Dst(raw_operand):** The raw operand of a general variable storing send message response
