1. Introduction

This specifies the Arm.ExperimentalMLOperations extended instruction set. It provides a mechanism to encode experimental ML operations in SPIR-V modules.

Import this extended instruction set using an OpExtInstImport Arm.ExperimentalMLOperations.<ver> instruction, where <ver> indicates the version.

2. Version

This extended instruction set is versioned. The version is specified via the import string. It must be an integer between 1 and the version specified at the beginning of this instruction set. Differences between the version are specified below.

3. Binary Form

CALL

Call an experimental ML operation.

Opcode is a literal integer that specifies the operation being called.

Parameters provides zero or more <id> operands, as required by the operation being called.
