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

922 | LOCAL FUNCTION | |
923 | ||
924 | demangle_signature -- demangle the signature part of a mangled name | |
925 | ||
926 | SYNOPSIS | |
927 | ||
928 | static int | |
929 | demangle_signature (struct work_stuff *work, const char **mangled, | |
930 | string *declp); | |
931 | ||
932 | DESCRIPTION | |
933 | ||
934 | Consume and demangle the signature portion of the mangled name. | |
935 | ||
936 | DECLP is the string where demangled output is being built. At | |
937 | entry it contains the demangled root name from the mangled name | |
938 | prefix. I.E. either a demangled operator name or the root function | |
939 | name. In some special cases, it may contain nothing. | |
940 | ||
941 | *MANGLED points to the current unconsumed location in the mangled | |
942 | name. As tokens are consumed and demangling is performed, the | |
943 | pointer is updated to continuously point at the next token to | |
944 | be consumed. | |
945 | ||
946 | Demangling GNU style mangled names is nasty because there is no | |
947 | explicit token that marks the start of the outermost function | |
948 | argument list. */ | |

2025 | ||
2026 | DECLP points to the buffer into which demangling is being done. | |
2027 | ||
2028 | *MANGLED points to the current token to be demangled. On input, | |
2029 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2030 | On exit, it points to the next token after the mangled class on | |
2031 | success, or the first unconsumed token on failure. | |
2032 | ||
2033 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2034 | we are demangling a constructor or destructor. In this case | |
2035 | we prepend "class::class" or "class::~class" to DECLP. | |
2036 | ||
2037 | Otherwise, we prepend "class::" to the current DECLP. | |
2038 | ||
2039 | Reset the constructor/destructor flags once they have been | |
2040 | "consumed". This allows demangle_class to be called later during | |
2041 | the same demangling, to do normal class demangling. | |
2042 | ||
2043 | Returns 1 if demangling is successful, 0 otherwise. | |

2104 | DESCRIPTION | |
2105 | ||
2106 | Consume and demangle the prefix of the mangled name. | |
2107 | ||
2108 | DECLP points to the string buffer into which demangled output is | |

2110 | the root function name, the demangled operator name, or in some | |
2111 | special cases either nothing or the completely demangled result. | |
2112 | ||
2113 | MANGLED points to the current pointer into the mangled name. As each | |
2114 | token of the mangled name is consumed, it is updated. Upon entry | |
2115 | the current mangled name pointer points to the first character of | |
2116 | the mangled name. Upon exit, it should point to the first character | |
2117 | of the signature if demangling was successful, or to the first | |
2118 | unconsumed character if demangling of the prefix was unsuccessful. | |

2863 | get_count -- convert an ascii count to integer, consuming tokens | |
2864 | ||
2865 | SYNOPSIS | |
2866 | ||
2867 | static int | |
2868 | get_count (const char **type, int *count) | |
2869 | ||
2870 | DESCRIPTION | |
2871 | ||
9d229989 JB |
2872 | Assume that *type points at a count in a mangled name; set |
2873 | *count to its value, and set *type to the next character after | |
2874 | the count. There are some weird rules in effect here. | |
2875 | ||
2876 | If *type does not point at a string of digits, return zero. | |
2877 | ||
2878 | If *type points at a string of digits followed by an | |
2879 | underscore, set *count to their value as an integer, advance | |
2880 | *type to point *after the underscore, and return 1. | |
2881 | ||
2882 | If *type points at a string of digits not followed by an | |
2883 | underscore, consume only the first digit. Set *count to its | |
2884 | value as an integer, leave *type pointing after that digit, | |
2885 | and return 1. | |
2886 | ||
2887 | The excuse for this odd behavior: in the ARM and HP demangling | |
2888 | styles, a type can be followed by a repeat count of the form | |
2889 | `Nxy', where: | |
2890 | ||
2891 | `x' is a single digit specifying how many additional copies | |
2892 | of the type to append to the argument list, and | |
2893 | ||
2894 | `y' is one or more digits, specifying the zero-based index of | |
2895 | the first repeated argument in the list. Yes, as you're | |
2896 | unmangling the name you can figure this out yourself, but | |
2897 | it's there anyway. | |
2898 | ||
2899 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
2900 | pointer to an integer (`Pi'), and then the next five arguments | |
2901 | are the same (`N5'), and the first repeat is the function's | |
2902 | second argument (`1'). | |

4412 | |
4413 | Note that, since HP's compiler generates object code straight from | |
4414 | C++ source, without going through an assembler, its mangled | |
4415 | identifiers can use all sorts of characters that no assembler would | |
4416 | tolerate, so the alphabet this function creates is a little odd. | |
4417 | Here are some sample mangled identifiers offered by HP: | |
4418 | ||
4419 | typeid*__XT24AddressIndExpClassMember_ | |
4420 | [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv | |
4421 | __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv | |
4422 | ||
4423 | This still seems really weird to me, since nowhere else in this | |
4424 | file is there anything to recognize curly brackets, parens, etc. | |
4425 | I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me | |
4426 | this is right, but I still strongly suspect that there's a | |
4427 | misunderstanding here. | |
4428 | ||
4429 | If we decide it's better for c++filt to use HP's assembler syntax | |
4430 | to scrape identifiers out of its input, here's the definition of | |
4431 | the symbol name syntax from the HP assembler manual: | |
4432 | ||
4433 | Symbols are composed of uppercase and lowercase letters, decimal | |
4434 | digits, dollar symbol, period (.), ampersand (&), pound sign(#) and | |
4435 | underscore (_). A symbol can begin with a letter, digit underscore or | |
4436 | dollar sign. If a symbol begins with a digit, it must contain a | |
4437 | non-digit character. | |
