dest>
signals whether there is a response to the message request. It can be either a null register,
a direct-addressed GRF register or a register-indirect GRF register. Otherwise,
hardware behavior is undefined. If <
dest>
is null,
there is no response to the request. Meanwhile,
the Response Length field in <
desc>
must be 0. Certain types of message requests,
such as memory write (store) through the Data Port,
do not want response data from the function unit. If so,
the posted destination operand can be null. If <
dest>
is a GRF register,
the register number is forwarded to the shared function. In this case,
the target function unit must send one or more response message phases back to the requesting thread. The number of response message phases must match the Response Length field in <
desc>
,
which of course cannot be zero. For some cases,
it could be an empty return message. An empty return message is defined as a single phase message with all channel enables turned off. The subregister number,
horizontal stride,
destination mask and type fields of <
dest>
are always valid and are used in part to generate on the WrEn. This is true even if <
dest>
is a null register (this is an exception for null as for most cases these fields are ignored by hardware). The 16-bit channel enables of the message sideband are formed based on the WrEn. Interpretation of the channel enable sideband signals is subject to the target external function. In general for a 'send' instruction with return messages,
they are used as the destination dword write mask for the GRF registers starting at <
dest>
. For a message that has multiple return phases,
the same set of channel enable signals applies to all the return phases. The destination dependency control,
{NoDDClr},
can be used in this instruction. This allows software to control the destination dependencies for multiple 'read'-type messages similar to that for multiple instructions using EU execution pipeline. As send does not check register dependencies for the post destination,
{NoDDChk} should not be used for this instruction.

The Illegal Opcode Exception Enable flag in cr0.1 is normally set so the normal processing of an illegal opcode is to transfer control to the System Routine.
The Illegal Opcode Exception Enable flag in cr0.1 is normally set so the normal processing of an illegal opcode is to transfer control to the System Routine. Instruction dispatch treats any unused 8-bit opcode (including bit 7 of the instruction,
reserved for future opcode expansion) as if it is the illegal opcode. The illegal opcode is zero because that byte value is more likely than most to be read via a wayward instruction pointer. The illegal instruction is an instruction only in the same way that a NULL pointer in software is a pointer. Both are special values indicating invalid instances.
The goto and join instructions enable unstructured program control flow. These instructions must be used with additional care where dangling channels can result without proper compiler checks,
meaning that it is expected that programs will navigate through these paths to reactivate the channels. Hardware does not provide native checks or reconvergence.
The join instruction makes the inactive channels active at the join IP if those channels are predicated. Any deactivated channels due to a goto instruction match the join IP are activated (qualified with predicates at join). If no IP is matched at this join,
the program goes to the next IP with the active channels which followed the program path up to the join instruction. If no active channels are present after executing the join instruction,
the program jumps to the offset specified by JIP instead of next IP. The join instruction is used in conjunction with a goto instruction. The join activates channels that are deactivated by the goto instruction. See the goto instruction for the deactivation rules. The goto and join instructions enable unstructured program control flow. These instructions must be used with additional care where dangling channels can result without proper compiler checks,
meaning that it is expected that programs will navigate through these paths to reactivate the channels. Hardware does not provide native checks or reconvergence. The following table describes the 32-bit JIP. In GEN binary,
JIP is at location src1 and must be of type D (signed DWord integer). JIP must be an immediate operand and is a signed 32-bit number. This value is added to IP pre-increment. If SPF is ON,
none of the PcIP are updated.
The mach should have channel enable from the destHI of IMUL,
the mov should have the channel enable from the destLO of IMUL. As mach is used to generate part of the 64-bit DWord integer results,
saturation modifier should not be used. In fact,
saturation modifier should not be used for any of these four instructions. Source and destination operands must be DWord integers. Source and destination must be of the same type,
signed integer or unsigned integer. If dst is UD,
src0 and src1 may be UD and/or D. However,
if any of src0 and src1 is D,
source modifier (abs) must be present to convert it to match with dst. If dst is D,
src0 and src1 must also be D. They cannot be UD as it may cause unexpected overflow because the computed results are limited to 64 bits.
The maclshould have channel enable from the destLO of IMUL. As maclis used to generate part of the 64-bit DWord integer results,
saturation modifier should not be used. In fact,
saturation modifier should not be used for any of these three instructions. Source and destination operands must be DWord integers. Source and destination must be of the same type,
signed integer or unsigned integer. If dst is UD,
src0 and src1 may be UD and/or D. However,
if any of src0 and src1 is D,

src0 and src1 must also be D. They cannot be UD as it may cause unexpected overflow because the computed results are limited to 64 bits.
The mul and mach instructions must have all channels enabled. The first mov should have channel enable from the destHI of IMUL,
the second mov should have the channel enable from the destLO of IMUL. As mach is used to generate part of the 64-bit DWord integer results,
saturation modifier should not be used. In fact,
