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 | |

908 | LOCAL FUNCTION | |
909 | ||
910 | demangle_signature -- demangle the signature part of a mangled name | |
911 | ||
912 | SYNOPSIS | |
913 | ||
914 | static int | |
915 | demangle_signature (struct work_stuff *work, const char **mangled, | |
916 | string *declp); | |
917 | ||
918 | DESCRIPTION | |
919 | ||
920 | Consume and demangle the signature portion of the mangled name. | |
921 | ||
922 | DECLP is the string where demangled output is being built. At | |
923 | entry it contains the demangled root name from the mangled name | |
924 | prefix. I.E. either a demangled operator name or the root function | |
925 | name. In some special cases, it may contain nothing. | |
926 | ||
927 | *MANGLED points to the current unconsumed location in the mangled | |
928 | name. As tokens are consumed and demangling is performed, the | |
929 | pointer is updated to continuously point at the next token to | |
930 | be consumed. | |
931 | ||
932 | Demangling GNU style mangled names is nasty because there is no | |
933 | explicit token that marks the start of the outermost function | |
934 | argument list. */ | |

1980 | DESCRIPTION | |
1981 | ||
1982 | DECLP points to the buffer into which demangling is being done. | |
1983 | ||
1984 | *MANGLED points to the current token to be demangled. On input, | |
1985 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
1986 | On exit, it points to the next token after the mangled class on | |
1987 | success, or the first unconsumed token on failure. | |
1988 | ||
1989 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
1990 | we are demangling a constructor or destructor. In this case | |
1991 | we prepend "class::class" or "class::~class" to DECLP. | |
1992 | ||
1993 | Otherwise, we prepend "class::" to the current DECLP. | |
1994 | ||
1995 | Reset the constructor/destructor flags once they have been | |
1996 | "consumed". This allows demangle_class to be called later during | |
1997 | the same demangling, to do normal class demangling. | |
1998 | ||
1999 | Returns 1 if demangling is successful, 0 otherwise. | |

2060 | DESCRIPTION | |
2061 | ||
2062 | Consume and demangle the prefix of the mangled name. | |

2064 | DECLP points to the string buffer into which demangled output is | |
2065 | placed. On entry, the buffer is empty. On exit it contains | |
2066 | the root function name, the demangled operator name, or in some | |
2067 | special cases either nothing or the completely demangled result. | |
2068 | ||
2069 | MANGLED points to the current pointer into the mangled name. As each | |
2070 | token of the mangled name is consumed, it is updated. Upon entry | |
2071 | the current mangled name pointer points to the first character of | |
2072 | the mangled name. Upon exit, it should point to the first character | |
2073 | of the signature if demangling was successful, or to the first | |
2074 | unconsumed character if demangling of the prefix was unsuccessful. | |

3711 | foo::foo (int, foo &ia, int, foo &ib, int, foo &ic); | |

3716 | ||

3719 | __3fooiRT0iT2iT2 | |
3720 | foo__FiR3fooiT1iT1 | |
3721 | ||
3722 | while lcc (and presumably other ARM style compilers as well) produces: | |

3725 | __ct__3fooFiR3fooT1T2T1T2 | |

3728 | previously seen types, while lucid/ARM bases its type numbers starting | |

3729 | at one and only considers types after it has seen the 'F' character |
3730 | indicating the start of the function args. For lucid/ARM style, we | |
