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

1364 | LOCAL FUNCTION | |
1365 | ||
1366 | demangle_signature -- demangle the signature part of a mangled name | |

1369 | ||
1370 | static int | |
1371 | demangle_signature (struct work_stuff *work, const char **mangled, | |
1372 | string *declp); | |
1373 | ||
1374 | DESCRIPTION | |
1375 | ||
1376 | Consume and demangle the signature portion of the mangled name. | |
1377 | ||
1378 | DECLP is the string where demangled output is being built. At | |
1379 | entry it contains the demangled root name from the mangled name | |
1380 | prefix. I.E. either a demangled operator name or the root function | |
1381 | name. In some special cases, it may contain nothing. | |
1382 | ||
1383 | *MANGLED points to the current unconsumed location in the mangled | |
1384 | name. As tokens are consumed and demangling is performed, the | |
1385 | pointer is updated to continuously point at the next token to | |
1386 | be consumed. | |
1387 | ||
1388 | Demangling GNU style mangled names is nasty because there is no | |
1389 | explicit token that marks the start of the outermost function | |
1390 | argument list. */ | |

2542 | ||
2543 | DESCRIPTION | |
2544 | ||
2545 | DECLP points to the buffer into which demangling is being done. | |
2546 | ||
2547 | *MANGLED points to the current token to be demangled. On input, | |
2548 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
2549 | On exit, it points to the next token after the mangled class on | |
2550 | success, or the first unconsumed token on failure. | |
2551 | ||
2552 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
2553 | we are demangling a constructor or destructor. In this case | |
2554 | we prepend "class::class" or "class::~class" to DECLP. | |
2555 | ||
2556 | Otherwise, we prepend "class::" to the current DECLP. | |
2557 | ||
2558 | Reset the constructor/destructor flags once they have been | |
2559 | "consumed". This allows demangle_class to be called later during | |
2560 | the same demangling, to do normal class demangling. | |
2561 | ||
2562 | Returns 1 if demangling is successful, 0 otherwise. | |

2688 | demangle_prefix -- consume the mangled name prefix and find signature | |
2689 | ||
2690 | SYNOPSIS | |
2691 | ||
2692 | static int | |
2693 | demangle_prefix (struct work_stuff *work, const char **mangled, | |
2694 | string *declp); | |
2695 | ||
2696 | DESCRIPTION | |
2697 | ||
2698 | Consume and demangle the prefix of the mangled name. | |
e8865c28 DB |
2699 | While processing the function name root, arrange to call |
2700 | demangle_signature if the root is ambiguous. | |
252b5132 RH |
2701 | |
2702 | DECLP points to the string buffer into which demangled output is | |
2703 | placed. On entry, the buffer is empty. On exit it contains | |
2704 | the root function name, the demangled operator name, or in some | |
2705 | special cases either nothing or the completely demangled result. | |
2706 | ||
2707 | MANGLED points to the current pointer into the mangled name. As each | |
2708 | token of the mangled name is consumed, it is updated. Upon entry | |
2709 | the current mangled name pointer points to the first character of | |
2710 | the mangled name. Upon exit, it should point to the first character | |
2711 | of the signature if demangling was successful, or to the first | |
2712 | unconsumed character if demangling of the prefix was unsuccessful. | |
2713 | ||
2714 | Returns 1 on success, 0 otherwise. | |

3239 | DESCRIPTION | |
3240 | ||
3241 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |
3242 | the mangled form of "Outer::Inner". The demangled output is | |
3243 | prepended or appended to the result string according to the | |
3244 | state of the append flag. | |
3245 | ||
3246 | If isfuncname is nonzero, then the qualified name we are building | |
3247 | is going to be used as a member function name, so if it is a | |
3248 | constructor or destructor function, append an appropriate | |
3249 | constructor or destructor name. I.E. for the above example, | |
3250 | the result for use as a constructor is "Outer::Inner::Inner" | |
3251 | and the result for use as a destructor is "Outer::Inner::~Inner". | |

3440 | get_count -- convert an ascii count to integer, consuming tokens | |
3441 | ||
3442 | SYNOPSIS | |
3443 | ||
3444 | static int | |
3445 | get_count (const char **type, int *count) | |
3446 | ||
3447 | DESCRIPTION | |
3448 | ||
3449 | Assume that *type points at a count in a mangled name; set | |
3450 | *count to its value, and set *type to the next character after | |
3451 | the count. There are some weird rules in effect here. | |
3452 | ||
3453 | If *type does not point at a string of digits, return zero. | |
3454 | ||
3455 | If *type points at a string of digits followed by an | |
3456 | underscore, set *count to their value as an integer, advance | |
3457 | *type to point *after the underscore, and return 1. | |
3458 | ||
3459 | If *type points at a string of digits not followed by an | |
3460 | underscore, consume only the first digit. Set *count to its | |
3461 | value as an integer, leave *type pointing after that digit, | |
3462 | and return 1. | |
3463 | ||
3464 | The excuse for this odd behavior: in the ARM and HP demangling | |
3465 | styles, a type can be followed by a repeat count of the form | |
3466 | `Nxy', where: | |
3467 | ||
3468 | `x' is a single digit specifying how many additional copies | |
3469 | of the type to append to the argument list, and | |
3470 | ||
3471 | `y' is one or more digits, specifying the zero-based index of | |
3472 | the first repeated argument in the list. Yes, as you're | |
3473 | unmangling the name you can figure this out yourself, but | |
3474 | it's there anyway. | |
3475 | ||
3476 | So, for example, in `bar__3fooFPiN51', the first argument is a | |
3477 | pointer to an integer (`Pi'), and then the next five arguments | |
3478 | are the same (`N5'), and the first repeat is the function's | |
3479 | second argument (`1'). | |

4375 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); | |

4383 | __3fooiRT0iT2iT2 | |
4384 | foo__FiR3fooiT1iT1 | |
4385 | ||
4386 | while lcc (and presumably other ARM style compilers as well) produces: | |

4389 | __ct__3fooFiR3fooT1T2T1T2 | |
4390 | ||
4391 | Note that g++ bases its type numbers starting at zero and counts all | |
4392 | previously seen types, while lucid/ARM bases its type numbers starting | |
4393 | at one and only considers types after it has seen the 'F' character | |
4394 | indicating the start of the function args. For lucid/ARM style, we | |
4395 | account for this difference by discarding any previously seen types when | |
