A compiler component for the generation of an optimal instruction sequence, the sequence including a compile-time unresolved reference to be resolved at runtime. The compiler generating a snippet list with entries corresponding to snippets defined for instructions includi ng unresolved compile-time references. A runtime helper routine being defined for resolving references at runtime. For each instruction with an unresolved reference, generating a snippet including dat a for identifying the reference and for permitting resolution of the reference at runtime by the runtime helper routine. The snippet also including a copy of the instruction containing the unresolved reference. The location in the compiled code for the unresolved instruction being written with a cal l instruction to the snippet. The runtime helper being invoked by the snippet at runtime to resol ve the references and to copy the unresolved code copy to the compiled code, with the references resolved.
