Extended Names

The enxref Compiler Option

When the enxref compiler option is specified, the compiler creates two extended name cross-references. Both of these cross-references are in two-column format. The first cross-reference is sorted according to extended name, or C identifier. The second cross-reference is sorted according to external symbol, or Link ID. Both cross-references include only the extended names of objects that were defined in the compilation; a __rent external variable is considered to be defined even if its only usage in the compilation is as a reference. Both of these cross-references are of limited value because the COOL utility can assign different external symbols to extended names during object code processing. The cross-references produced by COOL are more meaningful.
