-/* A C expression that returns the DBX register number for the compiler
- register number REGNO. In simple cases, the value of this expression may be
- REGNO itself. But sometimes there are some registers that the compiler
- knows about and DBX does not, or vice versa. In such cases, some register
- may need to have one number in the compiler and another for DBX.
-
- If two registers have consecutive numbers inside GNU CC, and they can be
- used as a pair to hold a multiword value, then they *must* have consecutive
- numbers after renumbering with `DBX_REGISTER_NUMBER'. Otherwise, debuggers
- will be unable to access such a pair, because they expect register pairs to
- be consecutive in their own numbering scheme.
-
- If you find yourself defining `DBX_REGISTER_NUMBER' in way that does not
- preserve register pairs, then what you must do instead is redefine the
- actual register numbering scheme.
-
- This declaration is required. */
