Detailed Description

ABIRewriteContext is the abstract interface that each dialect implements to perform ABI-specific rewrites on its operations.

The pass orchestrator calls these methods after ABI classification to rewrite function definitions and call sites.

getDialectNamespace()

virtual StringRef mlir::abi::ABIRewriteContext::getDialectNamespace ( ) const

pure virtual

Return the dialect namespace this context handles (e.g. "cir").

rewriteCallSite()

virtual LogicalResult mlir::abi::ABIRewriteContext::rewriteCallSite ( Operation * callOp, const FunctionClassification & fc, OpBuilder & rewriter )

pure virtual

Rewrite a call operation to match the callee's ABI-lowered signature.

This coerces arguments, handles indirect returns (sret), and adapts the call result back to the original high-level type.

Parameters

callOp	The call operation to rewrite.
fc	The ABI classification for the callee.
rewriter	The pattern rewriter to use for modifications.

Returns

success() if the call was rewritten.

rewriteFunctionDefinition()

virtual LogicalResult mlir::abi::ABIRewriteContext::rewriteFunctionDefinition ( FunctionOpInterface funcOp, const FunctionClassification & fc, OpBuilder & rewriter )

pure virtual

Rewrite a function definition to use ABI-lowered types.

This creates a new function with the lowered signature, rewrites the function body to adapt between the ABI types and the original high-level types, and replaces the original function.

Parameters

funcOp	The function to rewrite (via FunctionOpInterface).
fc	The ABI classification for this function.
rewriter	The pattern rewriter to use for modifications.

Returns

success() if the function was rewritten.
