class CfiModule
Defined at line 41 of file ../../src/lib/unwinder/cfi_module.h
Represents the Call Frame Information (CFI) from the .eh_frame and/or the .debug_frame section
of one ELF module.
This class doesn't cache the memory so if repeated lookups are required, it's recommended to use
a cached Memory implementation. Create via |FromLoadedElfModule|.
Public Methods
fit::result<Error, std::unique_ptr<CfiModule>> FromLoadedElfModule (const LoadedElfModule & loaded_elf_module)Constructs, validates, and loads a new |CfiModule| from the given |loaded_elf_module|. Returns
any errors that occur in any of the above steps, and releases any allocated memory. The object
is guaranteed to be valid if this function returns fit::ok().

fit::result<Error, bool> Step (Memory * stack, const Registers & current, Registers & next)Unwind one frame. The returned result will contain whether or not the next frame is a signal
frame in the case of success, otherwise the Error field will be populated with additional
information.
