Types

type AstBlock

type AstBlock struct {
	Index   int
	HasRefs bool
	Body    []ast.Stmt
	Phi     []ast.Stmt

}

type AstFunc

}

type ConverterConfig

type ConverterConfig struct {
	// ImportNameResolver function to get the actual import name.

	NamePrefix string

	// SsaValueRemap is used to replace ssa.Value with the specified ssa.Expr.
	// Note: Replacing ssa.Expr does not guarantee the correctness of the generated code.
	// When using it, strictly adhere to the value types.
	SsaValueRemap map[ssa.Value]ast.Expr

	// MarkerInstrCallback is called every time a MarkerInstr instruction is encountered.
	// Callback result is inserted into ast as is
