=====
|
|
|
|
This operand is a mask which controls indexing mode for operands of subsequent instructions.
|
|
Bits 0, 1 and 2 control indexing of *src0*, *src1* and *src2*, while bit 3 controls indexing of *dst*.
|
|
Value 1 enables indexing and value 0 disables it.
|
|

Bit Meaning
|
|
===== ========================================
|
|
0 Enables or disables *src0* indexing.
|
|
1 Enables or disables *src1* indexing.
|
|
2 Enables or disables *src2* indexing.
|
|
3 Enables or disables *dst* indexing.
|
|
===== ========================================
|
|
|
|
This operand may be specified as one of the following:
|
|
|
|
* An :ref:`integer_number<amdgpu_synid_integer_number>` or an :ref:`absolute_expression<amdgpu_synid_absolute_expression>`. The value must be in the range 0..15.
|
|
* A *gpr_idx* value described below.

Gpr_idx Value Syntax Description
|
|
==================================== ===========================================
|
|
gpr_idx(*<operands>*) Enable indexing for specified *operands*
|
|
and disable it for the rest.
|
|
*Operands* is a comma-separated list of
|
|
values which may include:
|
|
|
|
* "SRC0" - enable *src0* indexing.
|
|
|
|
* "SRC1" - enable *src1* indexing.
|
|
|
|
* "SRC2" - enable *src2* indexing.
|
|
|
|
* "DST" - enable *dst* indexing.
|
|
|
|
Each of these values may be specified only
|
|
once.
|
|
|
|
*Operands* list may be empty; this syntax
|
|
disables indexing for all operands.
