From: Janosch Frank <[email protected]> The architecture specifies specification exceptions for all unavailable subcodes.
The presence of subcodes is indicated by checking some query subcode. For example 6 will indicate that 3-6 are available. So future systems might call new subcodes to check for new features. This should not trigger a hw error, instead we return the architectured specification exception.
