403 | static int | |
404 | demangle_signature (string *declp, const char **mangled, | |

406 | ||
407 | DESCRIPTION | |
408 | ||
409 | Consume and demangle the signature portion of the mangled name. | |
410 | ||
411 | DECLP is the string where demangled output is being built. At | |
412 | entry it contains the demangled root name from the mangled name | |
413 | prefix. I.E. either a demangled operator name or the root function | |
414 | name. In some special cases, it may contain nothing. | |
415 | ||
416 | *MANGLED points to the current unconsumed location in the mangled | |
417 | name. As tokens are consumed and demangling is performed, the | |
418 | pointer is updated to continuously point at the next token to | |
419 | be consumed. | |
420 | ||
421 | Demangling GNU style mangled names is nasty because there is no | |
422 | explicit token that marks the start of the outermost function | |
423 | argument list. | |

805 | DECLP points to the buffer into which demangling is being done. | |
806 | ||
807 | *MANGLED points to the current token to be demangled. On input, | |
808 | it points to a mangled class (I.E. "3foo", "13verylongclass", etc.) | |
809 | On exit, it points to the next token after the mangled class on | |
810 | success, or the first unconsumed token on failure. | |
811 | ||
812 | If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then | |
813 | we are demangling a constructor or destructor. In this case | |
814 | we prepend "class::class" or "class::~class" to DECLP. | |
815 | ||
816 | Otherwise, we prepend "class::" to the current DECLP. | |
817 | ||
818 | Reset the constructor/destructor flags once they have been | |
819 | "consumed". This allows demangle_class to be called later during | |
820 | the same demangling, to do normal class demangling. | |
