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

1459 | static int | |
1460 | demangle_signature (struct work_stuff *work, const char **mangled, | |

1462 | ||
1463 | DESCRIPTION | |
1464 | ||
1465 | Consume and demangle the signature portion of the mangled name. | |
1466 | ||
1467 | DECLP is the string where demangled output is being built. At | |
1468 | entry it contains the demangled root name from the mangled name | |
1469 | prefix. I.E. either a demangled operator name or the root function | |
1470 | name. In some special cases, it may contain nothing. | |
1471 | ||
1472 | *MANGLED points to the current unconsumed location in the mangled | |
1473 | name. As tokens are consumed and demangling is performed, the | |
1474 | pointer is updated to continuously point at the next token to | |
1475 | be consumed. | |
1476 | ||
1477 | Demangling GNU style mangled names is nasty because there is no | |
1478 | explicit token that marks the start of the outermost function | |
1479 | argument list. */ | |

2633 | static int | |
2634 | demangle_class (struct work_stuff *work, const char **mangled, | |

2636 | ||
2637 | DESCRIPTION | |
2638 | ||
2639 | DECLP points to the buffer into which demangling is being done. | |
2640 | ||
2641 | *MANGLED points to the current token to be demangled. On input, | |
2642 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2643 | On exit, it points to the next token after the mangled class on | |
2644 | success, or the first unconsumed token on failure. | |
2645 | ||
2646 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2647 | we are demangling a constructor or destructor. In this case | |
2648 | we prepend "class::class" or "class::~class" to DECLP. | |
2649 | ||
2650 | Otherwise, we prepend "class::" to the current DECLP. | |
2651 | ||
2652 | Reset the constructor/destructor flags once they have been | |
2653 | "consumed". This allows demangle_class to be called later during | |
2654 | the same demangling, to do normal class demangling. | |
2655 | ||
2656 | Returns 1 if demangling is successful, 0 otherwise. | |

2790 | DESCRIPTION | |
2791 | ||
2792 | Consume and demangle the prefix of the mangled name. | |
e8865c28 DB |
2793 | While processing the function name root, arrange to call |
2794 | demangle_signature if the root is ambiguous. | |
252b5132 RH |
2795 | |
2796 | DECLP points to the string buffer into which demangled output is | |
2797 | placed. On entry, the buffer is empty. On exit it contains | |
2798 | the root function name, the demangled operator name, or in some | |
2799 | special cases either nothing or the completely demangled result. | |
2800 | ||
2801 | MANGLED points to the current pointer into the mangled name. As each | |
2802 | token of the mangled name is consumed, it is updated. Upon entry | |
2803 | the current mangled name pointer points to the first character of | |
2804 | the mangled name. Upon exit, it should point to the first character | |
2805 | of the signature if demangling was successful, or to the first | |
2806 | unconsumed character if demangling of the prefix was unsuccessful. | |
2807 | ||
2808 | Returns 1 on success, 0 otherwise. | |

3339 | ||
3340 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |
3341 | the mangled form of "Outer::Inner". The demangled output is | |
3342 | prepended or appended to the result string according to the | |
3343 | state of the append flag. | |
3344 | ||
3345 | If isfuncname is nonzero, then the qualified name we are building | |
3346 | is going to be used as a member function name, so if it is a | |
3347 | constructor or destructor function, append an appropriate | |
3348 | constructor or destructor name. I.E. for the above example, | |
3349 | the result for use as a constructor is "Outer::Inner::Inner" | |
3350 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3539 | get_count -- convert an ascii count to integer, consuming tokens | |
3540 | ||
3541 | SYNOPSIS | |
3542 | ||
3543 | static int | |
3544 | get_count (const char **type, int *count) | |
3545 | ||
3546 | DESCRIPTION | |
3547 | ||
3548 | Assume that *type points at a count in a mangled name; set | |
3549 | *count to its value, and set *type to the next character after | |
3550 | the count. There are some weird rules in effect here. | |
3551 | ||
3552 | If *type does not point at a string of digits, return zero. | |
3553 | ||
3554 | If *type points at a string of digits followed by an | |
3555 | underscore, set *count to their value as an integer, advance | |
3556 | *type to point *after the underscore, and return 1. | |
3557 | ||
3558 | If *type points at a string of digits not followed by an | |
3559 | underscore, consume only the first digit. Set *count to its | |
3560 | value as an integer, leave *type pointing after that digit, | |
3561 | and return 1. | |
3562 | ||
3563 | The excuse for this odd behavior: in the ARM and HP demangling | |
3564 | styles, a type can be followed by a repeat count of the form | |
3565 | `Nxy', where: | |
3566 | ||
3567 | `x' is a single digit specifying how many additional copies | |
3568 | of the type to append to the argument list, and | |
3569 | ||
3570 | `y' is one or more digits, specifying the zero-based index of | |
3571 | the first repeated argument in the list. Yes, as you're | |
3572 | unmangling the name you can figure this out yourself, but | |
3573 | it's there anyway. | |
3574 | ||
3575 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3576 | pointer to an integer (`Pi'), and then the next five arguments | |
3577 | are the same (`N5'), and the first repeat is the function's | |
3578 | second argument (`1'). | |

4539 | class foo { | |

4541 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); | |

4545 | void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; } | |
4546 | ||
4547 | g++ produces the names: | |
4548 | ||
4549 | __3fooiRT0iT2iT2 | |
4550 | foo__FiR3fooiT1iT1 | |
4551 | ||
4552 | while lcc (and presumably other ARM style compilers as well) produces: | |
4553 | ||
4554 | foo__FiR3fooT1T2T1T2 | |
4555 | __ct__3fooFiR3fooT1T2T1T2 | |
4556 | ||
4557 | Note that g++ bases its type numbers starting at zero and counts all | |
4558 | previously seen types, while lucid/ARM bases its type numbers starting | |
4559 | at one and only considers types after it has seen the 'F' character | |
4560 | indicating the start of the function args. For lucid/ARM style, we | |
4561 | account for this difference by discarding any previously seen types when | |
4562 | we see the 'F' character, and subtracting one from the type number | |
4563 | reference. | |
