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

1155 | DESCRIPTION | |
1156 | ||
1157 | Consume and demangle the signature portion of the mangled name. | |
1158 | ||
1159 | DECLP is the string where demangled output is being built. At | |
1160 | entry it contains the demangled root name from the mangled name | |
1161 | prefix. I.E. either a demangled operator name or the root function | |
1162 | name. In some special cases, it may contain nothing. | |
1163 | ||
1164 | *MANGLED points to the current unconsumed location in the mangled | |
1165 | name. As tokens are consumed and demangling is performed, the | |
1166 | pointer is updated to continuously point at the next token to | |
1167 | be consumed. | |
1168 | ||
1169 | Demangling GNU style mangled names is nasty because there is no | |
1170 | explicit token that marks the start of the outermost function | |
1171 | argument list. */ | |

2313 | DESCRIPTION | |
2314 | ||
2315 | DECLP points to the buffer into which demangling is being done. | |
2316 | ||
2317 | *MANGLED points to the current token to be demangled. On input, | |
2318 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2319 | On exit, it points to the next token after the mangled class on | |
2320 | success, or the first unconsumed token on failure. | |
2321 | ||
2322 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2323 | we are demangling a constructor or destructor. In this case | |
2324 | we prepend "class::class" or "class::~class" to DECLP. | |
2325 | ||
2326 | Otherwise, we prepend "class::" to the current DECLP. | |
2327 | ||
2328 | Reset the constructor/destructor flags once they have been | |
2329 | "consumed". This allows demangle_class to be called later during | |
2330 | the same demangling, to do normal class demangling. | |
2331 | ||
2332 | Returns 1 if demangling is successful, 0 otherwise. | |

3008 | ||
3009 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |
3010 | the mangled form of "Outer::Inner". The demangled output is | |
3011 | prepended or appended to the result string according to the | |
3012 | state of the append flag. | |
3013 | ||
3014 | If isfuncname is nonzero, then the qualified name we are building | |
3015 | is going to be used as a member function name, so if it is a | |
3016 | constructor or destructor function, append an appropriate | |
3017 | constructor or destructor name. I.E. for the above example, | |
3018 | the result for use as a constructor is "Outer::Inner::Inner" | |
3019 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3212 | ||
3213 | SYNOPSIS | |
3214 | ||
3215 | static int | |
3216 | get_count (const char **type, int *count) | |
3217 | ||
3218 | DESCRIPTION | |
3219 | ||
9d229989 JB |
3220 | Assume that *type points at a count in a mangled name; set |
3221 | *count to its value, and set *type to the next character after | |
3222 | the count. There are some weird rules in effect here. | |
3223 | ||
3224 | If *type does not point at a string of digits, return zero. | |
3225 | ||
3226 | If *type points at a string of digits followed by an | |
3227 | underscore, set *count to their value as an integer, advance | |
3228 | *type to point *after the underscore, and return 1. | |
3229 | ||
3230 | If *type points at a string of digits not followed by an | |
3231 | underscore, consume only the first digit. Set *count to its | |
3232 | value as an integer, leave *type pointing after that digit, | |
3233 | and return 1. | |
3234 | ||
3235 | The excuse for this odd behavior: in the ARM and HP demangling | |
3236 | styles, a type can be followed by a repeat count of the form | |
3237 | `Nxy', where: | |
3238 | ||
3239 | `x' is a single digit specifying how many additional copies | |
3240 | of the type to append to the argument list, and | |
3241 | ||
3242 | `y' is one or more digits, specifying the zero-based index of | |
3243 | the first repeated argument in the list. Yes, as you're | |
3244 | unmangling the name you can figure this out yourself, but | |
3245 | it's there anyway. | |
3246 | ||
3247 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3248 | pointer to an integer (`Pi'), and then the next five arguments | |
3249 | are the same (`N5'), and the first repeat is the function's | |
3250 | second argument (`1'). | |

4192 | foo__FiR3fooiT1iT1 | |

3eca405b JB |
4814 | |
4815 | Note that, since HP's compiler generates object code straight from | |
4816 | C++ source, without going through an assembler, its mangled | |
4817 | identifiers can use all sorts of characters that no assembler would | |
4818 | tolerate, so the alphabet this function creates is a little odd. | |
4819 | Here are some sample mangled identifiers offered by HP: | |
4820 | ||
4821 | typeid*__XT24AddressIndExpClassMember_ | |
4822 | [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv | |
4823 | __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv | |
4824 | ||
4825 | This still seems really weird to me, since nowhere else in this | |
4826 | file is there anything to recognize curly brackets, parens, etc. | |
4827 | I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me | |
4828 | this is right, but I still strongly suspect that there's a | |
4829 | misunderstanding here. | |
4830 | ||
4831 | If we decide it's better for c++filt to use HP's assembler syntax | |
4832 | to scrape identifiers out of its input, here's the definition of | |
4833 | the symbol name syntax from the HP assembler manual: | |
4834 | ||
4835 | Symbols are composed of uppercase and lowercase letters, decimal | |
4836 | digits, dollar symbol, period (.), ampersand (&), pound sign(#) and | |
4837 | underscore (_). A symbol can begin with a letter, digit underscore or | |
4838 | dollar sign. If a symbol begins with a digit, it must contain a | |
4839 | non-digit character. | |
