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 | |
94 | ensuring that it is the character that terminates the gcc<n>_compiled | |

1151 | demangle_signature (struct work_stuff *work, const char **mangled, | |

1153 | ||
1154 | DESCRIPTION | |
1155 | ||
1156 | Consume and demangle the signature portion of the mangled name. | |
1157 | ||
1158 | DECLP is the string where demangled output is being built. At | |
1159 | entry it contains the demangled root name from the mangled name | |
1160 | prefix. I.E. either a demangled operator name or the root function | |
1161 | name. In some special cases, it may contain nothing. | |
1162 | ||
1163 | *MANGLED points to the current unconsumed location in the mangled | |
1164 | name. As tokens are consumed and demangling is performed, the | |
1165 | pointer is updated to continuously point at the next token to | |
1166 | be consumed. | |
1167 | ||
1168 | Demangling GNU style mangled names is nasty because there is no | |
1169 | explicit token that marks the start of the outermost function | |
1170 | argument list. */ | |

2313 | ||
2314 | DESCRIPTION | |
2315 | ||
2316 | DECLP points to the buffer into which demangling is being done. | |
2317 | ||
2318 | *MANGLED points to the current token to be demangled. On input, | |
2319 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2320 | On exit, it points to the next token after the mangled class on | |
2321 | success, or the first unconsumed token on failure. | |
2322 | ||
2323 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2324 | we are demangling a constructor or destructor. In this case | |
2325 | we prepend "class::class" or "class::~class" to DECLP. | |
2326 | ||
2327 | Otherwise, we prepend "class::" to the current DECLP. | |
2328 | ||
2329 | Reset the constructor/destructor flags once they have been | |
2330 | "consumed". This allows demangle_class to be called later during | |
2331 | the same demangling, to do normal class demangling. | |
2332 | ||
2333 | Returns 1 if demangling is successful, 0 otherwise. | |

2464 | LOCAL FUNCTION | |
2465 | ||
2466 | demangle_prefix -- consume the mangled name prefix and find signature | |
2467 | ||
2468 | SYNOPSIS | |
2469 | ||
2470 | static int | |
2471 | demangle_prefix (struct work_stuff *work, const char **mangled, | |
2472 | string *declp); | |
2473 | ||
2474 | DESCRIPTION | |
2475 | ||
2476 | Consume and demangle the prefix of the mangled name. | |
e8865c28 DB |
2477 | While processing the function name root, arrange to call |
2478 | demangle_signature if the root is ambiguous. | |
252b5132 RH |
2479 | |
2480 | DECLP points to the string buffer into which demangled output is | |
2481 | placed. On entry, the buffer is empty. On exit it contains | |
2482 | the root function name, the demangled operator name, or in some | |
2483 | special cases either nothing or the completely demangled result. | |
2484 | ||
2485 | MANGLED points to the current pointer into the mangled name. As each | |
2486 | token of the mangled name is consumed, it is updated. Upon entry | |
2487 | the current mangled name pointer points to the first character of | |
2488 | the mangled name. Upon exit, it should point to the first character | |
2489 | of the signature if demangling was successful, or to the first | |
2490 | unconsumed character if demangling of the prefix was unsuccessful. | |
2491 | ||
2492 | Returns 1 on success, 0 otherwise. | |

3027 | DESCRIPTION | |
3028 | ||
3029 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |
3030 | the mangled form of "Outer::Inner". The demangled output is | |
3031 | prepended or appended to the result string according to the | |
3032 | state of the append flag. | |
3033 | ||
3034 | If isfuncname is nonzero, then the qualified name we are building | |
3035 | is going to be used as a member function name, so if it is a | |
3036 | constructor or destructor function, append an appropriate | |
3037 | constructor or destructor name. I.E. for the above example, | |
3038 | the result for use as a constructor is "Outer::Inner::Inner" | |
3039 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3233 | SYNOPSIS | |
3234 | ||
3235 | static int | |
3236 | get_count (const char **type, int *count) | |
3237 | ||
3238 | DESCRIPTION | |
3239 | ||
3240 | Assume that *type points at a count in a mangled name; set | |
3241 | *count to its value, and set *type to the next character after | |
3242 | the count. There are some weird rules in effect here. | |
3243 | ||
3244 | If *type does not point at a string of digits, return zero. | |
3245 | ||
3246 | If *type points at a string of digits followed by an | |
3247 | underscore, set *count to their value as an integer, advance | |
3248 | *type to point *after the underscore, and return 1. | |
3249 | ||
3250 | If *type points at a string of digits not followed by an | |
3251 | underscore, consume only the first digit. Set *count to its | |
3252 | value as an integer, leave *type pointing after that digit, | |
3253 | and return 1. | |
3254 | ||
3255 | The excuse for this odd behavior: in the ARM and HP demangling | |
3256 | styles, a type can be followed by a repeat count of the form | |
3257 | `Nxy', where: | |
3258 | ||
3259 | `x' is a single digit specifying how many additional copies | |
3260 | of the type to append to the argument list, and | |
3261 | ||
3262 | `y' is one or more digits, specifying the zero-based index of | |
3263 | the first repeated argument in the list. Yes, as you're | |
3264 | unmangling the name you can figure this out yourself, but | |
3265 | it's there anyway. | |
3266 | ||
3267 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3268 | pointer to an integer (`Pi'), and then the next five arguments | |
3269 | are the same (`N5'), and the first repeat is the function's | |
3270 | second argument (`1'). | |

4203 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); | |

4207 | void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; } | |
4208 | ||
4209 | g++ produces the names: | |

4211 | __3fooiRT0iT2iT2 | |
4212 | foo__FiR3fooiT1iT1 | |
4213 | ||
4214 | while lcc (and presumably other ARM style compilers as well) produces: | |

4217 | __ct__3fooFiR3fooT1T2T1T2 | |
4218 | ||
4219 | Note that g++ bases its type numbers starting at zero and counts all | |
4220 | previously seen types, while lucid/ARM bases its type numbers starting | |
4221 | at one and only considers types after it has seen the 'F' character | |
4222 | indicating the start of the function args. For lucid/ARM style, we | |
4223 | account for this difference by discarding any previously seen types when | |

4834 | |
4835 | Note that, since HP's compiler generates object code straight from | |
4836 | C++ source, without going through an assembler, its mangled | |
4837 | identifiers can use all sorts of characters that no assembler would | |
4838 | tolerate, so the alphabet this function creates is a little odd. | |
4839 | Here are some sample mangled identifiers offered by HP: | |
4840 | ||
4841 | typeid*__XT24AddressIndExpClassMember_ | |
4842 | [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv | |
4843 | __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv | |
4844 | ||
4845 | This still seems really weird to me, since nowhere else in this | |
4846 | file is there anything to recognize curly brackets, parens, etc. | |
4847 | I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me | |
4848 | this is right, but I still strongly suspect that there's a | |
4849 | misunderstanding here. | |
4850 | ||
4851 | If we decide it's better for c++filt to use HP's assembler syntax | |
4852 | to scrape identifiers out of its input, here's the definition of | |
4853 | the symbol name syntax from the HP assembler manual: | |
4854 | ||
4855 | Symbols are composed of uppercase and lowercase letters, decimal | |
4856 | digits, dollar symbol, period (.), ampersand (&), pound sign(#) and | |
4857 | underscore (_). A symbol can begin with a letter, digit underscore or | |
4858 | dollar sign. If a symbol begins with a digit, it must contain a | |
4859 | non-digit character. | |
