class | lldb_private::Module |
A plug-in interface definition class for object file parsers.
Object files belong to Module objects and know how to extract information from executable, shared library, and object (.o) files used by operating system runtime. The symbol table and section list for an object file.
Object files can be represented by the entire file, or by part of a file. An example of a partial file ObjectFile is one that contains information for one of multiple architectures in the same file.
Once an architecture is selected the object file information can be extracted from this abstract class.

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.

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.

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 base address of this object file.
This also sometimes referred to as the "preferred load address" or the "image base address". Addresses within object files are often expressed relative to this base. If this address corresponds to a specific section (usually the first byte of the first section) then the returned address will have this section set. Otherwise, the address will just have the offset member filled in, indicating that this represents a file address.

uint32_t ObjectFile::GetCacheHash | ( | ) |
Get a hash that can be used for caching object file releated information.
Data for object files can be cached between runs of debug sessions and a module can end up using a main file and a symbol file, both of which can be object files. So we need a unique hash that identifies an object file when storing cached data.

When the ObjectFile is a core file, lldb needs to locate the "binary" in the core file.
lldb can iterate over the pages looking for a valid binary, but some core files may have metadata describing where the main binary is exactly which removes ambiguity when there are multiple binaries present in the captured memory pages.
[out] | value | The address or offset (slide) where the binary is loaded in memory. LLDB_INVALID_ADDRESS for unspecified. If an offset is given, this offset should be added to the binary's file address to get the load address. |
[out] | value_is_offset | Specifies if value is a load address, or an offset to calculate the load address. |
[out] | uuid | If the uuid of the binary is specified, this will be set. If no UUID is available, will be cleared. |
[out] | type | Return the type of the binary, which will dictate which DynamicLoader plugin should be used. |

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. |

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.

This method returns the address of such a structure if the information can be resolved via entries in the object file.

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. We can ask the ObjectFile if it is such a file and should be avoided for things like settings breakpoints and doing function lookups for expressions.

We need a llvm::once_flag that we can use to avoid locking the module lock and deadlocking LLDB.
See comments in ObjectFile::GetSymtab() for the full details. We also need to be able to clear the symbol table, so we need to use a std::unique_ptr to a llvm::once_flag so if we clear the symbol table, we can have a new once flag to use when it is created again.
