1236 | DESCRIPTION | |||
1237 | ||||
1238 | Consume and demangle the signature portion of the mangled name. | |||
1239 | ||||
1240 | DECLP is the string where demangled output is being built. At | |||
1241 | entry it contains the demangled root name from the mangled name | |||
1242 | prefix. I.E. either a demangled operator name or the root function | |||
1243 | name. In some special cases, it may contain nothing. | |||
1244 | ||||
1245 | *MANGLED points to the current unconsumed location in the mangled | |||
1246 | name. As tokens are consumed and demangling is performed, the | |||
1247 | pointer is updated to continuously point at the next token to | |||
1248 | be consumed. | |||
1249 | ||||
1250 | Demangling GNU style mangled names is nasty because there is no | |||
1251 | explicit token that marks the start of the outermost function | |||
1252 | argument list. */ | |||

2405 | DESCRIPTION | |||
2406 | ||||
2407 | DECLP points to the buffer into which demangling is being done. | |||
2408 | ||||
2409 | *MANGLED points to the current token to be demangled. On input, | |||
2410 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |||
2411 | On exit, it points to the next token after the mangled class on | |||
2412 | success, or the first unconsumed token on failure. | |||
2413 | ||||
2414 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |||
2415 | we are demangling a constructor or destructor. In this case | |||
2416 | we prepend "class::class" or "class::~class" to DECLP. | |||
2417 | ||||
2418 | Otherwise, we prepend "class::" to the current DECLP. | |||
2419 | ||||
2420 | Reset the constructor/destructor flags once they have been | |||
2421 | "consumed". This allows demangle_class to be called later during | |||
2422 | the same demangling, to do normal class demangling. | |||
2423 | ||||
2424 | Returns 1 if demangling is successful, 0 otherwise. | |||

3094 | demangle_qualified -- demangle 'Q' qualified name strings | |||
3095 | ||||
3096 | SYNOPSIS | |||
3097 | ||||
3098 | static int | |||
3099 | demangle_qualified (struct work_stuff *, const char *mangled, | |||
3100 | string *result, int isfuncname, int append); | |||
3101 | ||||
3102 | DESCRIPTION | |||
3103 | ||||
3104 | Demangle a qualified name, such as "Q25Outer5Inner" which is | |||
3105 | the mangled form of "Outer::Inner". The demangled output is | |||
3106 | prepended or appended to the result string according to the | |||
3107 | state of the append flag. | |||
3108 | ||||
3109 | If isfuncname is nonzero, then the qualified name we are building | |||
3110 | is going to be used as a member function name, so if it is a | |||
3111 | constructor or destructor function, append an appropriate | |||
3112 | constructor or destructor name. I.E. for the above example, | |||
3113 | the result for use as a constructor is "Outer::Inner::Inner" | |||
3114 | and the result for use as a destructor is "Outer::Inner::~Inner". | |||
3115 | ||||
3116 | BUGS | |||
3117 | ||||
3118 | Numeric conversion is ASCII dependent (FIXME). | |||

3303 | get_count -- convert an ascii count to integer, consuming tokens | |||
3304 | ||||
3305 | SYNOPSIS | |||
3306 | ||||
3307 | static int | |||
3308 | get_count (const char **type, int *count) | |||
3309 | ||||
3310 | DESCRIPTION | |||
3311 | ||||
3312 | Assume that *type points at a count in a mangled name; set | |||
3313 | *count to its value, and set *type to the next character after | |||
3314 | the count. There are some weird rules in effect here. | |||
3315 | ||||
3316 | If *type does not point at a string of digits, return zero. | |||
3317 | ||||
3318 | If *type points at a string of digits followed by an | |||
3319 | underscore, set *count to their value as an integer, advance | |||
3320 | *type to point *after the underscore, and return 1. | |||
3321 | ||||
3322 | If *type points at a string of digits not followed by an | |||
3323 | underscore, consume only the first digit. Set *count to its | |||
3324 | value as an integer, leave *type pointing after that digit, | |||
3325 | and return 1. | |||
3326 | ||||
3327 | The excuse for this odd behavior: in the ARM and HP demangling | |||
3328 | styles, a type can be followed by a repeat count of the form | |||
3329 | `Nxy', where: | |||
3330 | ||||
3331 | `x' is a single digit specifying how many additional copies | |||
3332 | of the type to append to the argument list, and | |||
3333 | ||||
3334 | `y' is one or more digits, specifying the zero-based index of | |||
3335 | the first repeated argument in the list. Yes, as you're | |||
3336 | unmangling the name you can figure this out yourself, but | |||
3337 | it's there anyway. | |||
3338 | ||||
3339 | So, for example, in `bar__3fooFPiN51', the first argument is a | |||
3340 | pointer to an integer (`Pi'), and then the next five arguments | |||
3341 | are the same (`N5'), and the first repeat is the function's | |||
3342 | second argument (`1'). | |||
