◆ AllowAssemblyEmulationUnwindPlans()

bool ObjectFileMachO::AllowAssemblyEmulationUnwindPlans ( )
overridevirtual

Returns if the function bounds for symbols in this symbol file are likely accurate.

The unwinder can emulate the instructions of functions to understand prologue/epilogue code sequences, where registers are spilled on the stack, etc. This feature relies on having the correct start addresses of all functions. If the ObjectFile has a way to tell that symbols have been stripped and there's no way to reconstruct start addresses (e.g. LC_FUNCTION_STARTS on Mach-O, or eh_frame unwind info), the ObjectFile should indicate that assembly emulation should not be used for this module.

It is uncommon for this to return false. An ObjectFile needs to be sure that symbol start addresses are unavailable before false is returned. If it is unclear, this should return true.

Returns
Returns true if assembly emulation should be used for this module. Only returns false if the ObjectFile is sure that symbol addresses are insufficient for accurate assembly emulation.

◆ CalculateStrata()

ObjectFile::Strata ObjectFileMachO::CalculateStrata ( )
overridevirtual

The object file should be able to calculate the strata of the object file.

Many object files for platforms might be for either user space debugging or for kernel debugging. If your object file subclass can figure this out, it will help with debugger plug-in selection when it comes time to debug.

Returns
The calculated object file strata for the current object file.

◆ CalculateType()

ObjectFile::Type ObjectFileMachO::CalculateType ( )
overridevirtual

The object file should be able to calculate its type by looking at its file header and possibly the sections or other data in the object file.

The file type is used in the debugger to help select the correct plug- ins for the job at hand, so this is important to get right. If any eTypeXXX definitions do not match up with the type of file you are loading, please feel free to add a new enumeration value.

Returns
The calculated file type for the current object file.

Otherwise, the address will just have the offset member filled in, indicating that this represents a file address.

Parameters
[out]tidsFilled in with a vector of tid_t's that matches the number of threads in the corefile (ObjectFile::GetNumThreadContexts). If a tid is not specified for one of the corefile threads, that entry in the vector will have LLDB_INVALID_THREAD_ID and the caller should assign a tid to the thread that does not conflict with the ones provided in this array. As additional metadata are added, this method may return a tids vector with no thread id's specified at all; the corefile may only specify one of the other metadata.
Returns
Returns true if thread metadata was found in this corefile.

Extract the dependent modules from an object file.

If an object file has information about which other images it depends on (such as shared libraries), this function will provide the list. Since many executables or shared libraries may depend on the same files, FileSpecList::AppendIfUnique(const FileSpec &) should be used to make sure any files that are added are not already in the list.

Parameters

Often times dyld has symbols that mirror symbols in libc and other shared libraries (like "malloc" and "free") and the user does not want to stop in these shared libraries by default.
