62 | using various common values of CPLUS_MARKER, as well as any specific |

63 | one set at compile time, we maintain a string containing all the |

64 | commonly used ones, and check to see if the marker we are looking for |

65 | is in that string. CPLUS_MARKER is usually '$' on systems where the |
---|
66 | assembler can deal with that. Where the assembler can't, it's usually |

67 | '.' (but on many systems '.' is used for other things). We put the |

68 | current defined CPLUS_MARKER first (which defaults to '$'), followed |

69 | by the next most common value, followed by an explicit '$' in case |
---|
70 | the value of CPLUS_MARKER is not '$'. |
---|
71 | |
---|
72 | We could avoid this if we could just get g++ to tell us what the actual |
---|
73 | cplus marker character is as part of the debug information, perhaps by |

656 | SYNOPSIS |

657 | |

---|
662 | DESCRIPTION |
---|
663 | |
---|
664 | Consume and demangle the signature portion of the mangled name. |
---|
665 | |
---|
666 | DECLP is the string where demangled output is being built. At |
---|
667 | entry it contains the demangled root name from the mangled name |
---|
668 | prefix. I.E. either a demangled operator name or the root function |
---|
669 | name. In some special cases, it may contain nothing. |
---|
670 | |
---|
671 | *MANGLED points to the current unconsumed location in the mangled |
---|
672 | name. As tokens are consumed and demangling is performed, the |
---|
673 | pointer is updated to continuously point at the next token to |
---|
674 | be consumed. |
---|
675 | |
---|
676 | Demangling GNU style mangled names is nasty because there is no |
---|
677 | explicit token that marks the start of the outermost function |
---|
678 | argument list. */ |

---|
1367 | DESCRIPTION |
---|
1368 | |
---|
1369 | DECLP points to the buffer into which demangling is being done. |
---|
1370 | |
---|
1371 | *MANGLED points to the current token to be demangled. On input, |
---|
1372 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) |
---|
1373 | On exit, it points to the next token after the mangled class on |
---|
1374 | success, or the first unconsumed token on failure. |
---|
1375 | |
---|
1376 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then |
---|
1377 | we are demangling a constructor or destructor. In this case |
---|
1378 | we prepend "class::class" or "class::~class" to DECLP. |
---|
1379 | |
---|
1380 | Otherwise, we prepend "class::" to the current DECLP. |
---|
1381 | |
---|
1382 | Reset the constructor/destructor flags once they have been |
---|
1383 | "consumed". This allows demangle_class to be called later during |
---|
1384 | the same demangling, to do normal class demangling. |
---|
1385 | |
---|
1386 | Returns 1 if demangling is successful, 0 otherwise. |

1436 | |

1437 | Consume and demangle the prefix of the mangled name. |

1438 | |

1439 | DECLP points to the string buffer into which demangled output is |

1442 | special cases either nothing or the completely demangled result. |
---|
1443 | |
---|
1444 | MANGLED points to the current pointer into the mangled name. As each |
---|
1445 | token of the mangled name is consumed, it is updated. Upon entry |
---|
1446 | the current mangled name pointer points to the first character of |
---|
1447 | the mangled name. Upon exit, it should point to the first character |
---|
1448 | of the signature if demangling was successful, or to the first |

---|
1887 | DESCRIPTION |
---|
1888 | |
---|
1889 | Demangle a qualified name, such as "Q25Outer5Inner" which is |
---|
1890 | the mangled form of "Outer::Inner". The demangled output is |
---|
1891 | prepended or appended to the result string according to the |
---|
1892 | state of the append flag. |
---|
1893 | |
---|
1894 | If isfuncname is nonzero, then the qualified name we are building |
---|
1895 | is going to be used as a member function name, so if it is a |
---|
1896 | constructor or destructor function, append an appropriate |
---|
1897 | constructor or destructor name. I.E. for the above example, |
---|
1898 | the result for use as a constructor is "Outer::Inner::Inner" |
---|
1899 | and the result for use as a destructor is "Outer::Inner::~Inner". |

---|
2611 | |
---|
2612 | Note that g++ differs significantly from ARM and lucid style mangling |
---|
2613 | with regards to references to previously seen types. For example, given |
---|
2614 | the source fragment: |
---|
2615 | |
---|
2616 | class foo { |
---|
2617 | public: |
---|
2618 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); |
---|
2619 | }; |
---|
2620 | |
---|
2621 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; } |
---|
2622 | void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; } |
---|
2623 | |
---|
2624 | g++ produces the names: |
---|
2625 | |
---|
2626 | __3fooiRT0iT2iT2 |
---|
2627 | foo__FiR3fooiT1iT1 |
---|
2628 | |
---|
2629 | while lcc (and presumably other ARM style compilers as well) produces: |
---|
2630 | |
---|
2631 | foo__FiR3fooT1T2T1T2 |
---|
2632 | __ct__3fooFiR3fooT1T2T1T2 |
---|
2633 | |
---|
2634 | Note that g++ bases it's type numbers starting at zero and counts all |
---|
2635 | previously seen types, while lucid/ARM bases it's type numbers starting |
---|
2636 | at one and only considers types after it has seen the 'F' character |
---|
2637 | indicating the start of the function args. For lucid/ARM style, we |
---|
2638 | account for this difference by discarding any previously seen types when |
---|
2639 | we see the 'F' character, and subtracting one from the type number |
---|
2640 | reference. |
