40 | * \brief Legalizes a QNN expr. Contains specifically two types of Legalizations. First, |
41 | * converts/Lowers an expression containing QNN ops to an expression containing only core Relay ops. |
42 | * Each QNN op is lowered to a sequence of exisiting Relay ops. This is a target-independent pass. |
43 | * One can register the lowering/transformation function for this op using FTVMQnnCanonicalize |
44 | * attr_name for FTVMLegalize op attribute. Second, as opposed to Relay Legalize, this one legalizes |
45 | * only QNN ops. One can register a transformation/legalization function for an op by using the |
46 | * FTVMQnnLegalize attr_name for FTVMLegalize op attribute. The isolation of QNN and Relay Legalize |
47 | * gives us separation of concerns, leading to a better software practice. The legalization can be |
48 | * configured to happen per target. |
