1 2.7 Include Local Symbols: '-L'
1 ===============================
1 
1 Symbols beginning with system-specific local label prefixes, typically
1 '.L' for ELF systems or 'L' for traditional a.out systems, are called
1 "local symbols".  ⇒Symbol Names.  Normally you do not see such
1 symbols when debugging, because they are intended for the use of
1 programs (like compilers) that compose assembler programs, not for your
1 notice.  Normally both 'as' and 'ld' discard such symbols, so you do not
1 normally debug with them.
1 
1    This option tells 'as' to retain those local symbols in the object
1 file.  Usually if you do this you also tell the linker 'ld' to preserve
1 those symbols.
