示例1: constructArrayTypeDIE
/// constructArrayTypeDIE - Construct array type DIE from DICompositeType.
void CompileUnit::constructArrayTypeDIE(DIE &Buffer,
DICompositeType *CTy) {
Buffer.setTag(dwarf::DW_TAG_array_type);
if (CTy->getTag() == dwarf::DW_TAG_vector_type)
addUInt(&Buffer, dwarf::DW_AT_GNU_vector, dwarf::DW_FORM_flag, 1);
// Emit derived type.
addType(&Buffer, CTy->getTypeDerivedFrom());
DIArray Elements = CTy->getTypeArray();
// Get an anonymous type for index type.
DIE *IdxTy = getIndexTyDie();
if (!IdxTy) {
// Construct an anonymous type for index type.
IdxTy = new DIE(dwarf::DW_TAG_base_type);
addUInt(IdxTy, dwarf::DW_AT_byte_size, 0, sizeof(int32_t));
addUInt(IdxTy, dwarf::DW_AT_encoding, dwarf::DW_FORM_data1,
dwarf::DW_ATE_signed);
addDie(IdxTy);
setIndexTyDie(IdxTy);
}
// Add subranges to array type.
for (unsigned i = 0, N = Elements.getNumElements(); i < N; ++i) {
DIDescriptor Element = Elements.getElement(i);
if (Element.getTag() == dwarf::DW_TAG_subrange_type)

}
}
示例2: constructTypeDIE
/// constructTypeDIE - Construct derived type die from DIDerivedType.
void CompileUnit::constructTypeDIE(DIE &Buffer, DIDerivedType DTy) {
// Get core information.
StringRef Name = DTy.getName();
uint64_t Size = DTy.getSizeInBits() >> 3;
unsigned Tag = DTy.getTag();
// FIXME - Workaround for templates.
if (Tag == dwarf::DW_TAG_inheritance) Tag = dwarf::DW_TAG_reference_type;
Buffer.setTag(Tag);
// Map to main type, void will not have a type.
DIType FromTy = DTy.getTypeDerivedFrom();
addType(&Buffer, FromTy);
// Add name if not anonymous or intermediate type.
if (!Name.empty())
addString(&Buffer, dwarf::DW_AT_name, dwarf::DW_FORM_string, Name);
// Add size if non-zero (derived types might be zero-sized.)
if (Size)
addUInt(&Buffer, dwarf::DW_AT_byte_size, 0, Size);
// Add source line info if available and TyDesc is not a forward declaration.
if (!DTy.isForwardDecl())
