[MS Demangler] Fail gracefully on invalid pointer types. Once we detect a 'P', we know we a pointer type is upcoming, so we make some assumptions about the output that follows. If those assumptions didn't hold, we would assert. Instead, we should fail gracefully and propagate the error up. llvm-svn: 349169

llvm-undname: Fix more crashes and asserts on invalid inputs For functions whose callers don't check that enough input is present, add checks at the start of the function that enough input is there and set Error otherwise. For functions that return AST objects, return nullptr instead of incomplete AST objects with nullptr fields if an error occurred during the function. Introduce a new function demangleDeclarator() for the sequence demangleFullyQualifiedSymbolName(); demangleEncodedSymbol() and use it in the two places that had this sequence. Let this new function check that ConversionOperatorIdentifiers have a valid TargetType. Some of the bad inputs found by oss-fuzz, others by inspection.

llvm-undname: Fix another crash-on-invalid This fixes a regression from https://reviews.llvm.org/D60354. We used to SymbolNode *Symbol = demangleEncodedSymbol(MangledName, QN); if (Symbol) { Symbol->Name = QN; } but changed that to SymbolNode *Symbol = demangleEncodedSymbol(MangledName, QN); if (Error) return nullptr; Symbol->Name = QN; and one branch somewhere returned a nullptr without setting Error. Looking at the code changed in r340083 and r340710 that branch looks like a remnant from an earlier attempt to demangle RTTI descriptors that has since been rewritten -- so just remove this branch. It shouldn't change behavior for correctly mangled symbols. llvm-svn: 358112

llvm-undname: More coverage-related cleanups - The loop in demangleFunctionParameterList() only exits on Error, @, and Z. All 3 cases were handled, so the rest of the function is DEMANGLE_UNREACHABLE. - The loop in demangleTemplateParameterList() always returns on Error, so there's no need to check for that in the loop header and after the loop. - Add test cases for invalid function parameter manglings. - Add a (redundant) test case for a simple template parameter list mangling. - Add a test case pointing out that varargs functions aren't demangled correctly. llvm-svn: 362540

llvm-undname: Fix nullptr deref on invalid conversion operator names in template args A ConversionOperatorIdentifierNode has a TargetType which is read when printing it, but if the ConversionOperatorIdentifierNode appears in a template argument there's nothing that can provide the TargetType. Normally the COIN is a symbol (leaf) name and takes its TargetType from the symbol's type, but in a template argument context the COIN can only be either a non-leaf name piece or a type, and must hence be invalid. Similar to the COIN check in demangleDeclarator(). Found by oss-fuzz. llvm-svn: 358421

Since StructorIndentifierNodes are always leaf names, we can just reject them as well. Found by oss-fuzz. llvm-svn: 358491
