+// 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.
