81 | /* In order to allow a single demangler executable to demangle strings | |
82 | using various common values of CPLUS_MARKER, as well as any specific | |
83 | one set at compile time, we maintain a string containing all the | |
84 | commonly used ones, and check to see if the marker we are looking for | |
85 | is in that string. CPLUS_MARKER is usually '$' on systems where the | |
86 | assembler can deal with that. Where the assembler can't, it's usually | |
87 | '.' (but on many systems '.' is used for other things). We put the | |
88 | current defined CPLUS_MARKER first (which defaults to '$'), followed | |
89 | by the next most common value, followed by an explicit '$' in case | |
90 | the value of CPLUS_MARKER is not '$'. | |
91 | ||
92 | We could avoid this if we could just get g++ to tell us what the actual | |
93 | cplus marker character is as part of the debug information, perhaps by | |

956 | LOCAL FUNCTION | |

958 | demangle_signature -- demangle the signature part of a mangled name | |

961 | ||
962 | static int | |
963 | demangle_signature (struct work_stuff *work, const char **mangled, | |
964 | string *declp); | |
965 | ||
966 | DESCRIPTION | |
967 | ||
968 | Consume and demangle the signature portion of the mangled name. | |
969 | ||
970 | DECLP is the string where demangled output is being built. At | |
971 | entry it contains the demangled root name from the mangled name | |
972 | prefix. I.E. either a demangled operator name or the root function | |
973 | name. In some special cases, it may contain nothing. | |
974 | ||
975 | *MANGLED points to the current unconsumed location in the mangled | |
976 | name. As tokens are consumed and demangling is performed, the | |
977 | pointer is updated to continuously point at the next token to | |
978 | be consumed. | |
979 | ||
980 | Demangling GNU style mangled names is nasty because there is no | |
981 | explicit token that marks the start of the outermost function | |
982 | argument list. */ | |

2090 | ||
2091 | DECLP points to the buffer into which demangling is being done. | |
2092 | ||
2093 | *MANGLED points to the current token to be demangled. On input, | |
2094 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2095 | On exit, it points to the next token after the mangled class on | |
2096 | success, or the first unconsumed token on failure. | |
2097 | ||
2098 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2099 | we are demangling a constructor or destructor. In this case | |
2100 | we prepend "class::class" or "class::~class" to DECLP. | |
2101 | ||
2102 | Otherwise, we prepend "class::" to the current DECLP. | |
2103 | ||
2104 | Reset the constructor/destructor flags once they have been | |
2105 | "consumed". This allows demangle_class to be called later during | |
2106 | the same demangling, to do normal class demangling. | |

2169 | DESCRIPTION | |
2170 | ||
2171 | Consume and demangle the prefix of the mangled name. | |
2172 | ||
2173 | DECLP points to the string buffer into which demangled output is | |

2175 | the root function name, the demangled operator name, or in some | |
2176 | special cases either nothing or the completely demangled result. | |
2177 | ||
2178 | MANGLED points to the current pointer into the mangled name. As each | |
2179 | token of the mangled name is consumed, it is updated. Upon entry | |
2180 | the current mangled name pointer points to the first character of | |
2181 | the mangled name. Upon exit, it should point to the first character | |
2182 | of the signature if demangling was successful, or to the first | |

2712 | string *result, int isfuncname, int append); | |
2713 | ||
2714 | DESCRIPTION | |
2715 | ||
2716 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |
2717 | the mangled form of "Outer::Inner". The demangled output is | |
2718 | prepended or appended to the result string according to the | |
2719 | state of the append flag. | |
2720 | ||
2721 | If isfuncname is nonzero, then the qualified name we are building | |
2722 | is going to be used as a member function name, so if it is a | |
2723 | constructor or destructor function, append an appropriate | |
2724 | constructor or destructor name. I.E. for the above example, | |
2725 | the result for use as a constructor is "Outer::Inner::Inner" | |
2726 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

2920 | SYNOPSIS | |
2921 | ||
2922 | static int | |
2923 | get_count (const char **type, int *count) | |
2924 | ||
2925 | DESCRIPTION | |
2926 | ||
9d229989 JB |
2927 | Assume that *type points at a count in a mangled name; set |
2928 | *count to its value, and set *type to the next character after | |
2929 | the count. There are some weird rules in effect here. | |
2930 | ||
2931 | If *type does not point at a string of digits, return zero. | |
2932 | ||
2933 | If *type points at a string of digits followed by an | |
2934 | underscore, set *count to their value as an integer, advance | |
2935 | *type to point *after the underscore, and return 1. | |
2936 | ||
2937 | If *type points at a string of digits not followed by an | |
2938 | underscore, consume only the first digit. Set *count to its | |
2939 | value as an integer, leave *type pointing after that digit, | |
2940 | and return 1. | |
2941 | ||
2942 | The excuse for this odd behavior: in the ARM and HP demangling | |
2943 | styles, a type can be followed by a repeat count of the form | |
2944 | `Nxy', where: | |
2945 | ||
2946 | `x' is a single digit specifying how many additional copies | |
2947 | of the type to append to the argument list, and | |
2948 | ||
2949 | `y' is one or more digits, specifying the zero-based index of | |
2950 | the first repeated argument in the list. Yes, as you're | |
2951 | unmangling the name you can figure this out yourself, but | |
2952 | it's there anyway. | |
2953 | ||
2954 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
2955 | pointer to an integer (`Pi'), and then the next five arguments | |
2956 | are the same (`N5'), and the first repeat is the function's | |
2957 | second argument (`1'). | |

4482 | /* Return the string of non-alnum characters that may occur |
4483 | as a valid symbol name component in an HP object file. | |
3eca405b JB |
4484 | |
4485 | Note that, since HP's compiler generates object code straight from | |
4486 | C++ source, without going through an assembler, its mangled | |
4487 | identifiers can use all sorts of characters that no assembler would | |
4488 | tolerate, so the alphabet this function creates is a little odd. | |
4489 | Here are some sample mangled identifiers offered by HP: | |
4490 | ||
4491 | typeid*__XT24AddressIndExpClassMember_ | |
4492 | [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv | |
4493 | __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv | |
4494 | ||
4495 | This still seems really weird to me, since nowhere else in this | |
4496 | file is there anything to recognize curly brackets, parens, etc. | |
4497 | I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me | |
4498 | this is right, but I still strongly suspect that there's a | |
4499 | misunderstanding here. | |
4500 | ||
4501 | If we decide it's better for c++filt to use HP's assembler syntax | |
4502 | to scrape identifiers out of its input, here's the definition of | |
4503 | the symbol name syntax from the HP assembler manual: | |
4504 | ||
4505 | Symbols are composed of uppercase and lowercase letters, decimal | |
4506 | digits, dollar symbol, period (.), ampersand (&), pound sign(#) and | |
4507 | underscore (_). A symbol can begin with a letter, digit underscore or | |
4508 | dollar sign. If a symbol begins with a digit, it must contain a | |
4509 | non-digit character. | |
4510 | ||
4511 | So have fun. */ | |
