xsymHppa - extract the symbol table from an HP-PA SOM COFF object module
xsymHppa < objMod > symTbl
This tool reads an object module (HP-PA SOM format) from standard input and writes an object module to standard output. The output module contains only the symbol table, with no code, but is otherwise a normal, executable object module.
This tool is used to generate the VxWorks symbol table, vxWorks.sym.
