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

1416 | static int | |
1417 | demangle_signature (struct work_stuff *work, const char **mangled, | |
1418 | string *declp); | |
1419 | ||
1420 | DESCRIPTION | |
1421 | ||
1422 | Consume and demangle the signature portion of the mangled name. | |
1423 | ||
1424 | DECLP is the string where demangled output is being built. At | |
1425 | entry it contains the demangled root name from the mangled name | |
1426 | prefix. I.E. either a demangled operator name or the root function | |
1427 | name. In some special cases, it may contain nothing. | |
1428 | ||
1429 | *MANGLED points to the current unconsumed location in the mangled | |
1430 | name. As tokens are consumed and demangling is performed, the | |
1431 | pointer is updated to continuously point at the next token to | |
1432 | be consumed. | |
1433 | ||
1434 | Demangling GNU style mangled names is nasty because there is no | |
1435 | explicit token that marks the start of the outermost function | |
1436 | argument list. */ | |

2590 | ||
2591 | DESCRIPTION | |
2592 | ||
2593 | DECLP points to the buffer into which demangling is being done. | |
2594 | ||
2595 | *MANGLED points to the current token to be demangled. On input, | |
2596 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2597 | On exit, it points to the next token after the mangled class on | |
2598 | success, or the first unconsumed token on failure. | |
2599 | ||
2600 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2601 | we are demangling a constructor or destructor. In this case | |
2602 | we prepend "class::class" or "class::~class" to DECLP. | |
2603 | ||
2604 | Otherwise, we prepend "class::" to the current DECLP. | |
2605 | ||
2606 | Reset the constructor/destructor flags once they have been | |
2607 | "consumed". This allows demangle_class to be called later during | |
2608 | the same demangling, to do normal class demangling. | |
2609 | ||
2610 | Returns 1 if demangling is successful, 0 otherwise. | |

2744 | DESCRIPTION | |
2745 | ||
2746 | Consume and demangle the prefix of the mangled name. | |
e8865c28 DB |
2747 | While processing the function name root, arrange to call |
2748 | demangle_signature if the root is ambiguous. | |
252b5132 RH |
2749 | |
2750 | DECLP points to the string buffer into which demangled output is | |
2751 | placed. On entry, the buffer is empty. On exit it contains | |
2752 | the root function name, the demangled operator name, or in some | |
2753 | special cases either nothing or the completely demangled result. | |
2754 | ||
2755 | MANGLED points to the current pointer into the mangled name. As each | |
2756 | token of the mangled name is consumed, it is updated. Upon entry | |
2757 | the current mangled name pointer points to the first character of | |
2758 | the mangled name. Upon exit, it should point to the first character | |
2759 | of the signature if demangling was successful, or to the first | |
2760 | unconsumed character if demangling of the prefix was unsuccessful. | |
2761 | ||
2762 | Returns 1 on success, 0 otherwise. | |

3293 | ||
3294 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |

3296 | prepended or appended to the result string according to the | |
3297 | state of the append flag. | |
3298 | ||
3299 | If isfuncname is nonzero, then the qualified name we are building | |
3300 | is going to be used as a member function name, so if it is a | |
3301 | constructor or destructor function, append an appropriate | |
3302 | constructor or destructor name. I.E. for the above example, | |
3303 | the result for use as a constructor is "Outer::Inner::Inner" | |
3304 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3495 | SYNOPSIS | |
3496 | ||
3497 | static int | |
3498 | get_count (const char **type, int *count) | |
3499 | ||
3500 | DESCRIPTION | |
3501 | ||
3502 | Assume that *type points at a count in a mangled name; set | |
3503 | *count to its value, and set *type to the next character after | |
3504 | the count. There are some weird rules in effect here. | |
3505 | ||
3506 | If *type does not point at a string of digits, return zero. | |
3507 | ||
3508 | If *type points at a string of digits followed by an | |
3509 | underscore, set *count to their value as an integer, advance | |
3510 | *type to point *after the underscore, and return 1. | |
3511 | ||
3512 | If *type points at a string of digits not followed by an | |
3513 | underscore, consume only the first digit. Set *count to its | |
3514 | value as an integer, leave *type pointing after that digit, | |
3515 | and return 1. | |
3516 | ||
3517 | The excuse for this odd behavior: in the ARM and HP demangling | |
3518 | styles, a type can be followed by a repeat count of the form | |
3519 | `Nxy', where: | |
3520 | ||
3521 | `x' is a single digit specifying how many additional copies | |
3522 | of the type to append to the argument list, and | |
3523 | ||
3524 | `y' is one or more digits, specifying the zero-based index of | |
3525 | the first repeated argument in the list. Yes, as you're | |
3526 | unmangling the name you can figure this out yourself, but | |
3527 | it's there anyway. | |
3528 | ||
3529 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3530 | pointer to an integer (`Pi'), and then the next five arguments | |
3531 | are the same (`N5'), and the first repeat is the function's | |
3532 | second argument (`1'). | |

4493 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); | |

4497 | void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; } | |
4498 | ||
4499 | g++ produces the names: | |

4501 | __3fooiRT0iT2iT2 | |
4502 | foo__FiR3fooiT1iT1 | |
4503 | ||
4504 | while lcc (and presumably other ARM style compilers as well) produces: | |

4507 | __ct__3fooFiR3fooT1T2T1T2 | |
4508 | ||
4509 | Note that g++ bases its type numbers starting at zero and counts all | |
4510 | previously seen types, while lucid/ARM bases its type numbers starting | |
4511 | at one and only considers types after it has seen the 'F' character | |
4512 | indicating the start of the function args. For lucid/ARM style, we | |
4513 | account for this difference by discarding any previously seen types when | |
