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). */ | |

1474 | demangle_signature (struct work_stuff *work, const char **mangled, | |

1476 | ||
1477 | DESCRIPTION | |
1478 | ||
1479 | Consume and demangle the signature portion of the mangled name. | |
1480 | ||
1481 | DECLP is the string where demangled output is being built. At | |
1482 | entry it contains the demangled root name from the mangled name | |
1483 | prefix. I.E. either a demangled operator name or the root function | |
1484 | name. In some special cases, it may contain nothing. | |
1485 | ||
1486 | *MANGLED points to the current unconsumed location in the mangled | |
1487 | name. As tokens are consumed and demangling is performed, the | |
1488 | pointer is updated to continuously point at the next token to | |
1489 | be consumed. | |
1490 | ||
1491 | Demangling GNU style mangled names is nasty because there is no | |
1492 | explicit token that marks the start of the outermost function | |
1493 | argument list. */ | |

2650 | ||
2651 | DESCRIPTION | |
2652 | ||
2653 | DECLP points to the buffer into which demangling is being done. | |
2654 | ||
2655 | *MANGLED points to the current token to be demangled. On input, | |
2656 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2657 | On exit, it points to the next token after the mangled class on | |
2658 | success, or the first unconsumed token on failure. | |
2659 | ||
2660 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2661 | we are demangling a constructor or destructor. In this case | |
2662 | we prepend "class::class" or "class::~class" to DECLP. | |
2663 | ||
2664 | Otherwise, we prepend "class::" to the current DECLP. | |
2665 | ||
2666 | Reset the constructor/destructor flags once they have been | |
2667 | "consumed". This allows demangle_class to be called later during | |
2668 | the same demangling, to do normal class demangling. | |
2669 | ||
2670 | Returns 1 if demangling is successful, 0 otherwise. | |

2804 | DESCRIPTION | |
2805 | ||
2806 | Consume and demangle the prefix of the mangled name. | |
e8865c28 DB |
2807 | While processing the function name root, arrange to call |
2808 | demangle_signature if the root is ambiguous. | |
252b5132 RH |
2809 | |
2810 | DECLP points to the string buffer into which demangled output is | |
2811 | placed. On entry, the buffer is empty. On exit it contains | |
2812 | the root function name, the demangled operator name, or in some | |
2813 | special cases either nothing or the completely demangled result. | |
2814 | ||
2815 | MANGLED points to the current pointer into the mangled name. As each | |
2816 | token of the mangled name is consumed, it is updated. Upon entry | |
2817 | the current mangled name pointer points to the first character of | |
2818 | the mangled name. Upon exit, it should point to the first character | |
2819 | of the signature if demangling was successful, or to the first | |
2820 | unconsumed character if demangling of the prefix was unsuccessful. | |
2821 | ||
2822 | Returns 1 on success, 0 otherwise. | |

3356 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |

3358 | prepended or appended to the result string according to the | |

3360 | ||
3361 | If isfuncname is nonzero, then the qualified name we are building | |

3555 | get_count -- convert an ascii count to integer, consuming tokens | |
3556 | ||
3557 | SYNOPSIS | |
3558 | ||
3559 | static int | |
3560 | get_count (const char **type, int *count) | |
3561 | ||
3562 | DESCRIPTION | |
3563 | ||
3564 | Assume that *type points at a count in a mangled name; set | |
3565 | *count to its value, and set *type to the next character after | |
3566 | the count. There are some weird rules in effect here. | |
3567 | ||
3568 | If *type does not point at a string of digits, return zero. | |
3569 | ||
3570 | If *type points at a string of digits followed by an | |
3571 | underscore, set *count to their value as an integer, advance | |
3572 | *type to point *after the underscore, and return 1. | |
3573 | ||
3574 | If *type points at a string of digits not followed by an | |
3575 | underscore, consume only the first digit. Set *count to its | |
3576 | value as an integer, leave *type pointing after that digit, | |
3577 | and return 1. | |
3578 | ||
3579 | The excuse for this odd behavior: in the ARM and HP demangling | |
3580 | styles, a type can be followed by a repeat count of the form | |
3581 | `Nxy', where: | |
3582 | ||
3583 | `x' is a single digit specifying how many additional copies | |
3584 | of the type to append to the argument list, and | |
3585 | ||
3586 | `y' is one or more digits, specifying the zero-based index of | |
3587 | the first repeated argument in the list. Yes, as you're | |
3588 | unmangling the name you can figure this out yourself, but | |
3589 | it's there anyway. | |
3590 | ||
3591 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3592 | pointer to an integer (`Pi'), and then the next five arguments | |
3593 | are the same (`N5'), and the first repeat is the function's | |
3594 | second argument (`1'). | |
