The helper class to build type name based on DIE properties.

It builds synthetic name based on explicit attributes: DW_AT_name, DW_AT_linkage_name or based on implicit attributes(DW_AT_decl*). Names for specific DIEs(like subprograms, template classes...) include additional attributes: subprogram parameters, template parameters, array ranges. Examples of built name:

class A { } : {8}A

namspace llvm { class A { } } : {1}llvm{8}A

template structure B { } : {F}B<{0}int>

void foo ( int p1, float p3 ) : {a}void foo({0}int, {0}int)

int *ptr; : {c}ptr {0}int

int var; : {d}var

These names is used to refer DIEs describing types.

Error SyntheticTypeNameBuilder::addDIETypeName ( UnitEntryPairTy InputUnitEntryPair, std::optional< std::pair< size_t, size_t > > ChildIndex, bool AssignNameToTypeDescriptor ) protected

Analyze InputUnitEntryPair for the type name and possibly assign built type name to the DIE's type info.

NOTE: while analyzing types we may create different kind of names for the same type depending on whether the type is part of another type. f.e. DW_TAG_formal_parameter would receive "{02}01" name when examined alone. Or "{0}int" name when it is a part of a function name: {a}void foo({0}int). The AssignNameToTypeDescriptor tells whether the type name is part of another type name and then should not be assigned to DIE type descriptor.
