[question] Why there is not a conversion pattern for `tt.func`

[CoTinker]

As the title says, triton-to-linalg convert tt.func use walk rather than conversion pattern.

triton-shared/lib/Conversion/TritonToLinalg/TritonToLinalgPass.cpp

Lines 187 to 215 in 2b728ad

	// Convert tt.func and tt.return into func's counterparts
	moduleOp.walk([&](triton::FuncOp func) {
	OpBuilder builder(func);
	auto name = func.getName();
	auto type = func.getFunctionType();
	SmallVector<DictionaryAttr> argAttrs, resAttrs;
	func.getAllArgAttrs(argAttrs);
	func.getAllResultAttrs(resAttrs);
	auto funcFunc = builder.create<func::FuncOp>(func.getLoc(), name, type);
	funcFunc.setAllArgAttrs(argAttrs);
	funcFunc.setAllResultAttrs(resAttrs);
	auto &funcFuncBody = funcFunc.getBody();
	auto &funcBody = func.getBody();
	IRMapping map;
	funcBody.cloneInto(&funcFuncBody, map);
	for (Block &block : funcFuncBody.getBlocks()) {
	auto term = block.getTerminator();
	builder.setInsertionPoint(term);
	builder.create<func::ReturnOp>(func.getLoc(), term->getOperands());
	term->erase();
	}
	func.erase();
	});

this should be a legacy issue 😂

Okay, I see. Thanks.
