示例1: emitDwarfDIE
void AsmPrinter::emitDwarfDIE(const DIE &Die) const {
// Emit the code (index) for the abbreviation.
if (isVerbose())
OutStreamer->AddComment("Abbrev [" + Twine(Die.getAbbrevNumber()) + "] 0x" +
Twine::utohexstr(Die.getOffset()) + ":0x" +
Twine::utohexstr(Die.getSize()) + " " +
dwarf::TagString(Die.getTag()));
EmitULEB128(Die.getAbbrevNumber());
// Emit the DIE attribute values.
for (const auto &V : Die.values()) {
dwarf::Attribute Attr = V.getAttribute();
assert(V.getForm() && "Too many attributes for DIE (check abbreviation)");
if (isVerbose()) {
OutStreamer->AddComment(dwarf::AttributeString(Attr));
if (Attr == dwarf::DW_AT_accessibility)
OutStreamer->AddComment(
dwarf::AccessibilityString(V.getDIEInteger().getValue()));
}
// Emit an attribute using the defined form.
V.EmitValue(this);
}
// Emit the DIE children if any.
if (Die.hasChildren()) {
for (auto &Child : Die.children())
emitDwarfDIE(Child);
OutStreamer->AddComment("End Of Children Mark");
EmitInt8(0);
}
}示例2: computeSizeAndOffset
// Compute the size and offset of a DIE. The offset is relative to start of the
// CU. It returns the offset after laying out the DIE.
unsigned DwarfFile::computeSizeAndOffset(DIE &Die, unsigned Offset) {
// Record the abbreviation.
assignAbbrevNumber(Die.getAbbrev());
// Get the abbreviation for this DIE.
const DIEAbbrev &Abbrev = Die.getAbbrev();
// Set DIE offset
Die.setOffset(Offset);
// Start the size with the size of abbreviation code.
Offset += getULEB128Size(Die.getAbbrevNumber());
const SmallVectorImpl<DIEValue *> &Values = Die.getValues();
const SmallVectorImpl<DIEAbbrevData> &AbbrevData = Abbrev.getData();
// Size the DIE attribute values.
for (unsigned i = 0, N = Values.size(); i < N; ++i)
// Size attribute value.
Offset += Values[i]->SizeOf(Asm, AbbrevData[i].getForm());
// Get the children.
const auto &Children = Die.getChildren();
// Size the DIE children if any.
if (!Children.empty()) {
assert(Abbrev.hasChildren() && "Children flag not set");
for (auto &Child : Children)
Offset = computeSizeAndOffset(*Child, Offset);
// End of children marker.
Offset += sizeof(int8_t);
}
Die.setSize(Offset - Die.getOffset());
return Offset;
