/* ELF interface header file for the C++ demangler. */

/*
   The C++ demangler is shared by the ELF library and the C++
   translator.  Because the translator is used on many different
   operating systems, not all of which use ELF, we have set up this
   library so that it may be compiled to work with or without libelf.
   The default is *not* to compile for ELF.  Define the macro "ELF" 
   in the makefile to compile for ELF.
*/

/*
   These macros tack an _elf_..._demangle_ATTLC onto all global names
   which should be hidden outside of the demangler module.  The only
   visible names at this time are the functions "demangle" and 
   "demangle_withlen", which are mapped to "elf_demangle" and 
   "elf_demangle_withlen" for the ELF library.  Note that we use
   "_elf_..._demangle_ATTLC" to hide names even for the translator.  
   We could have used just "_..._demangle_ATTLC" but since the names 
   are hidden why should we bother.
