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

1307 | DESCRIPTION | |
1308 | ||
1309 | Consume and demangle the signature portion of the mangled name. | |
1310 | ||
1311 | DECLP is the string where demangled output is being built. At | |
1312 | entry it contains the demangled root name from the mangled name | |
1313 | prefix. I.E. either a demangled operator name or the root function | |
1314 | name. In some special cases, it may contain nothing. | |
1315 | ||
1316 | *MANGLED points to the current unconsumed location in the mangled | |
1317 | name. As tokens are consumed and demangling is performed, the | |
1318 | pointer is updated to continuously point at the next token to | |
1319 | be consumed. | |
1320 | ||
1321 | Demangling GNU style mangled names is nasty because there is no | |
1322 | explicit token that marks the start of the outermost function | |
1323 | argument list. */ | |

2465 | DESCRIPTION | |
2466 | ||
2467 | DECLP points to the buffer into which demangling is being done. | |
2468 | ||
2469 | *MANGLED points to the current token to be demangled. On input, | |
2470 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2471 | On exit, it points to the next token after the mangled class on | |
2472 | success, or the first unconsumed token on failure. | |
2473 | ||
2474 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2475 | we are demangling a constructor or destructor. In this case | |
2476 | we prepend "class::class" or "class::~class" to DECLP. | |
2477 | ||
2478 | Otherwise, we prepend "class::" to the current DECLP. | |
2479 | ||
2480 | Reset the constructor/destructor flags once they have been | |
2481 | "consumed". This allows demangle_class to be called later during | |
2482 | the same demangling, to do normal class demangling. | |
2483 | ||
2484 | Returns 1 if demangling is successful, 0 otherwise. | |

3179 | ||
3180 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |

3182 | prepended or appended to the result string according to the | |

3184 | ||
3185 | If isfuncname is nonzero, then the qualified name we are building | |
3186 | is going to be used as a member function name, so if it is a | |

3189 | the result for use as a constructor is "Outer::Inner::Inner" | |
3190 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3388 | ||
3389 | DESCRIPTION | |
3390 | ||
9d229989 JB |
3391 | Assume that *type points at a count in a mangled name; set |
3392 | *count to its value, and set *type to the next character after | |
3393 | the count. There are some weird rules in effect here. | |
3394 | ||
3395 | If *type does not point at a string of digits, return zero. | |
3396 | ||
3397 | If *type points at a string of digits followed by an | |
3398 | underscore, set *count to their value as an integer, advance | |
3399 | *type to point *after the underscore, and return 1. | |
3400 | ||
3401 | If *type points at a string of digits not followed by an | |
3402 | underscore, consume only the first digit. Set *count to its | |
3403 | value as an integer, leave *type pointing after that digit, | |
3404 | and return 1. | |
3405 | ||
3406 | The excuse for this odd behavior: in the ARM and HP demangling | |
3407 | styles, a type can be followed by a repeat count of the form | |
3408 | `Nxy', where: | |
3409 | ||
3410 | `x' is a single digit specifying how many additional copies | |
3411 | of the type to append to the argument list, and | |
3412 | ||
3413 | `y' is one or more digits, specifying the zero-based index of | |
3414 | the first repeated argument in the list. Yes, as you're | |
3415 | unmangling the name you can figure this out yourself, but | |
3416 | it's there anyway. | |
3417 | ||
3418 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3419 | pointer to an integer (`Pi'), and then the next five arguments | |
3420 | are the same (`N5'), and the first repeat is the function's | |
3421 | second argument (`1'). | |

3eca405b JB |
4985 | |
4986 | Note that, since HP's compiler generates object code straight from | |
4987 | C++ source, without going through an assembler, its mangled | |
4988 | identifiers can use all sorts of characters that no assembler would | |
4989 | tolerate, so the alphabet this function creates is a little odd. | |
4990 | Here are some sample mangled identifiers offered by HP: | |
4991 | ||
4992 | typeid*__XT24AddressIndExpClassMember_ | |
4993 | [Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv | |
4994 | __ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv | |
4995 | ||
4996 | This still seems really weird to me, since nowhere else in this | |
4997 | file is there anything to recognize curly brackets, parens, etc. | |
4998 | I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me | |
4999 | this is right, but I still strongly suspect that there's a | |
5000 | misunderstanding here. | |
5001 | ||
5002 | If we decide it's better for c++filt to use HP's assembler syntax | |
5003 | to scrape identifiers out of its input, here's the definition of | |
5004 | the symbol name syntax from the HP assembler manual: | |
5005 | ||
5006 | Symbols are composed of uppercase and lowercase letters, decimal | |
5007 | digits, dollar symbol, period (.), ampersand (&), pound sign(#) and | |
5008 | underscore (_). A symbol can begin with a letter, digit underscore or | |
5009 | dollar sign. If a symbol begins with a digit, it must contain a | |
5010 | non-digit character. | |
