/**
|
|
* Replace the external call statements that are Store operations involving
|
|
* multiple output with the external call themselves.
|
|
*
|
|
* This pass is applicable in scenarios where the external call statements
|
|
* containing Store operations that have multiple output arguments. Replacing
|
|
* them can simplify the IR.
|
|
*
|
|
* When applied, this pass will traverse the statements within block and
|
|
identify
|
|
* the external call statements which are Store operations with multiple output.
|
|
* For each matching Store operation, this pass replaces the entire Store
|
|
expression
|
|
* with the external call expression itself.
|
|
|
|
* Examples:
|
|
* 1. Multi-Output External Call:
|
|
* Input IR:
|
|
* Store(target, Call(extern_func, args, write_args))
|
|
* Output IR:
|
|
* Call(extern_func, args, write_args)
|
|
*
|
|
* 2. Single-Output External Call (No Change):
|
|
* Input IR:
|
|
* Store(target, Call(extern_func, args, {}))
|
|
* Output IR:
|
|
* Store(target, Call(extern_func, args, {}))
