Detailed Description

CIR-specific implementation of mlir::abi::ABIRewriteContext.

The driver pass (CallConvLoweringPass) computes a FunctionClassification for each cir.func / cir.call and dispatches to this class to perform the actual IR rewriting using cir dialect operations.

Holds a reference to the module's DataLayout for coercion alignment queries. The DataLayout must outlive the rewrite context.

◆ rewriteFunctionAddress()

void CIRABIRewriteContext::rewriteFunctionAddress	(	cir::GetGlobalOp	addrOp,
		cir::FuncOp	funcOp,
		mlir::OpBuilder &	builder )

Retype addrOp, which holds the address of funcOp, to the signature funcOp was rewritten to, and cast it back so existing uses keep the type they were built for.

A no-op when the ABI left funcOp's type alone. Call after funcOp has been rewritten. Not an override, since taking a function's address has no counterpart in the generic contract.
