As for the other instructions, some of them do seem wasteful, I agree.

(Though I realised after writing this that TEST can't operate solely on a memory location, so if GCC has its heart set on using DEC and TEST, it actually has to generate what it did... using SUB instead would be more efficient I think.)

Kind regards,

Alastair.
