-
-   Note that, since HP's compiler generates object code straight from
-   C++ source, without going through an assembler, its mangled
-   identifiers can use all sorts of characters that no assembler would
-   tolerate, so the alphabet this function creates is a little odd.
-   Here are some sample mangled identifiers offered by HP:
-
-       typeid*__XT24AddressIndExpClassMember_
-       [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv
-       __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv
-
-   This still seems really weird to me, since nowhere else in this
-   file is there anything to recognize curly brackets, parens, etc.
-   I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me
-   this is right, but I still strongly suspect that there's a
-   misunderstanding here.
-
-   If we decide it's better for c++filt to use HP's assembler syntax
-   to scrape identifiers out of its input, here's the definition of
-   the symbol name syntax from the HP assembler manual:
-
-       Symbols are composed of uppercase and lowercase letters, decimal
-       digits, dollar symbol, period (.), ampersand (&), pound sign(#) and
-       underscore (_). A symbol can begin with a letter, digit underscore or
-       dollar sign. If a symbol begins with a digit, it must contain a
-       non-digit character.
-
-   So have fun.  */
