6.1.27 Z: Omit Trivial Symbols From Symbol File

Some local symbols are compiler generated and not of interest in debugging. The -Z option will suppress from the symbol file all local symbols that have the form of a single alphabetic character, followed by a digit string. The set of letters that can start a trivial symbol is currently “klfLSu“. The -Z option will strip any local symbols starting with one of these letters, and followed by a digit string.
