Detailed Description

"Partial" demangler.

This supports demangling a string into an AST (typically an intermediate stage in itaniumDemangle) and querying certain properties or partially printing the demangled name.

Member Function Documentation

◆ finishDemangle()

char * ItaniumPartialDemangler::finishDemangle ( char Buf,
size_t *  N 
) const

Just print the entire mangled name into Buf.

Buf and N behave like the second and third parameters to __cxa_demangle.

Definition at line 538 of file ItaniumDemangle.cpp.

References assert(), N, and printNode().

◆ getFunctionBaseName()

char * ItaniumPartialDemangler::getFunctionBaseName ( char Buf,
size_t *  N 
) const

Get the base name of a function.

This doesn't include trailing template arguments, ie for "a::b<int>" this function returns "b".

Definition at line 424 of file ItaniumDemangle.cpp.

References llvm::sampleprof::Base, getName(), isFunction(), N, Name, and printNode().

◆ getFunctionDeclContextName()

char * ItaniumPartialDemangler::getFunctionDeclContextName ( char Buf,
size_t *  N 
) const

Get the context name for a function.

For "a::b::c", this function returns "a::b".

Definition at line 453 of file ItaniumDemangle.cpp.

References llvm::sampleprof::Base, LocalName::Encoding, getName(), isFunction(), N, ModuleEntity::Name, Name, and Node::print().

◆ getFunctionName()

char * ItaniumPartialDemangler::getFunctionName ( char Buf,
size_t *  N 
) const

Get the entire name of this function.

Definition at line 497 of file ItaniumDemangle.cpp.

References getName(), isFunction(), N, Name, and printNode().

◆ getFunctionParameters()

char * ItaniumPartialDemangler::getFunctionParameters ( char Buf,
size_t *  N 
) const

Get the parameters for this function.

Definition at line 504 of file ItaniumDemangle.cpp.

References isFunction(), N, and NodeArray::printWithComma().

◆ getFunctionReturnType()

char * ItaniumPartialDemangler::getFunctionReturnType ( char Buf,
size_t *  N 
) const

Definition at line 521 of file ItaniumDemangle.cpp.

References isFunction(), and N.

◆ hasFunctionQualifiers()

bool ItaniumPartialDemangler::hasFunctionQualifiers ( ) const

If this function has any cv or reference qualifiers.

These imply that the function is a non-static member function.

Definition at line 543 of file ItaniumDemangle.cpp.

References assert(), FrefQualNone, FunctionEncoding::getCVQuals(), isFunction(), and QualNone.

◆ isCtorOrDtor()

bool ItaniumPartialDemangler::isCtorOrDtor ( ) const

If this symbol describes a constructor or destructor.

Definition at line 551 of file ItaniumDemangle.cpp.

References llvm::sampleprof::Base, getName(), N, and Name.

◆ isData()

bool ItaniumPartialDemangler::isData ( ) const

If this symbol describes a variable.

Definition at line 595 of file ItaniumDemangle.cpp.

References isFunction(), and isSpecialName().

◆ isFunction()

bool ItaniumPartialDemangler::isFunction ( ) const

◆ isSpecialName()

bool ItaniumPartialDemangler::isSpecialName ( ) const

If this symbol is a <special-name>.

These are generally implicitly generated by the implementation, such as vtables and typeinfo names.

Definition at line 589 of file ItaniumDemangle.cpp.

References assert().

Referenced by isData().

◆ operator=()

ItaniumPartialDemangler & ItaniumPartialDemangler::operator= ( ItaniumPartialDemangler &&  Other)

Definition at line 399 of file ItaniumDemangle.cpp.

References llvm::Other, and std::swap().

◆ partialDemangle()

bool ItaniumPartialDemangler::partialDemangle ( const char MangledName)

Demangle into an AST.

Subsequent calls to the rest of the member functions implicitly operate on the AST this produces.

Returns
true on error, false otherwise
