-// stack_frame_cpu.h: CPU-specific StackFrame extensions.
-//
-// These types extend the StackFrame structure to carry CPU-specific register
-// state. They are defined in this header instead of stack_frame.h to
-// avoid the need to include minidump_format.h when only the generic
-// StackFrame type is needed.
