- global variables (e.g., current_regcache, current_frame,
- current_gdbarch or selected_frame) and instead refer to the FRAME
- or REGCACHE that has been passed into the containing function as
- parameters. Consequently, the change typically involves modifying
- the containing function so that it takes a FRAME or REGCACHE
- parameter. In the case of an architecture vector method, there
- should already be a non-deprecated variant that is parameterized
- with FRAME or REGCACHE. */
