◆ addFunctionRange()

void CompileUnit::addFunctionRange ( uint64_t LowPC,
uint64_t HighPC,
int64_t PCOffset )

◆ addLabelLowPc()

int64_t PcOffset )

◆ addNameAccelerator()

◆ addNamespaceAccelerator()

◆ addObjCAccelerator()

Add various accelerator entries for Die with Name which is stored in the string table at Offset.

Name must be an Objective-C selector.

Definition at line 197 of file DWARFLinkerCompileUnit.cpp.

◆ addTypeAccelerator()

Add a type accelerator entry for Die with Name which is stored in the string table at Offset.

Definition at line 209 of file DWARFLinkerCompileUnit.cpp.

◆ computeNextUnitOffset()
