- 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.
