- migrate to the overhauled register cache.
-
- The problem is that some architectures specify different sized raw
- and cooked (nee virtual) register sizes. They shouldn't. Instead,
- all architectures should just implement a gdbarch_register_type().
- That can be used to compute all needed register attributes. While
- waiting for the conversion, provide compatibility macros that keep
- old code working. */
